WEBVTT
00:04:37.730 --> 00:04:38.630
Lucy Morgans.
00:04:38.630 --> 00:04:40.230
Thank you, ma'am, you may begin?
00:04:41.760 --> 00:04:43.010
Thanks very much.
00:04:43.010 --> 00:04:44.840
Good morning, everyone.
00:04:44.840 --> 00:04:46.730
On behalf of Caroline Thomas Jacobs,
00:04:46.730 --> 00:04:48.980
Director of the Wildfire Safety Division,
00:04:48.980 --> 00:04:51.630
thank you for joining us today
for our technical workshops
00:04:51.630 --> 00:04:54.803
on the 2021 Wildfire Mitigation Plan updates.
00:04:55.640 --> 00:04:58.380
My name is Lucy Morgans and
I'm the acting program manager
00:04:58.380 --> 00:05:01.360
in the mitigation branch,
which has it's a team of experts
00:05:01.360 --> 00:05:04.560
and to taking a review of the utility 2021
00:05:04.560 --> 00:05:06.523
Wildfire Mitigation Plan Update.
00:05:07.590 --> 00:05:11.070
Our team, along with the team
from Cal Fire, is responsible
00:05:11.070 --> 00:05:14.290
for evaluating the 2021
Wildfire Mitigation Plan updates
00:05:14.290 --> 00:05:16.390
and support for final decision of approval
00:05:16.390 --> 00:05:19.283
or denial of each wildfire mitigation plan.
00:05:20.950 --> 00:05:22.820
The goal of today's workshop is
00:05:22.820 --> 00:05:26.190
to allow PacifiCorp, Bear
Valley Electrical Service,
00:05:26.190 --> 00:05:29.690
Liberty Utilities, Horizon
West, and Trans Bay Cable
00:05:29.690 --> 00:05:34.449
to present and explain their
2021 WMP Plan Update focusing
00:05:34.449 --> 00:05:37.710
on specific areas and allowing stakeholders
00:05:37.710 --> 00:05:40.673
in general public to ask
questions of the utility.
00:05:42.910 --> 00:05:46.090
As opposed to last year,
where we had each utility present
00:05:46.090 --> 00:05:49.700
their plans, this year in an effort
00:05:49.700 --> 00:05:51.830
to streamline our process and emancipation
00:05:51.830 --> 00:05:54.010
of the challenges of conducting a workshop
00:05:54.010 --> 00:05:55.270
in a remote environment, we thought
00:05:55.270 --> 00:05:58.130
to have the utilities
hone in their presentations
00:05:58.130 --> 00:06:00.100
on three key areas.
00:06:00.100 --> 00:06:02.030
These are risk assessment mapping
00:06:02.030 --> 00:06:04.100
and resource allocation methodology
00:06:05.330 --> 00:06:06.817
with design and system hardening,
00:06:06.817 --> 00:06:10.160
including inspections and mitigation choices,
00:06:10.160 --> 00:06:11.950
and lastly, vegetation management,
00:06:11.950 --> 00:06:15.093
includes an inspection, strategy, and pilot.
00:06:16.770 --> 00:06:18.900
So a quick notes about, say the review
00:06:18.900 --> 00:06:21.070
of the Wildfire Mitigation Plans pursuant
00:06:21.070 --> 00:06:23.180
to Assembly Bill 1054 happens
00:06:23.180 --> 00:06:26.030
outside the formal Commission proceeding.
00:06:26.030 --> 00:06:27.580
However, the Commission will take actions
00:06:27.580 --> 00:06:30.340
to ratify not the Wildfire
Safety Divisions actions
00:06:30.340 --> 00:06:32.440
on the Wildfire Mitigation Plans.
00:06:32.440 --> 00:06:35.050
Please be informed of all
communication practices involved
00:06:35.050 --> 00:06:38.700
in discussion with Commissioners
or other decision-makers.
00:06:38.700 --> 00:06:40.610
Before we discuss the agenda for today,
00:06:40.610 --> 00:06:43.883
I wanted to take a moment to
go over a brief safety message.
00:06:45.010 --> 00:06:47.603
So if we could just have slide one, please.
00:06:50.750 --> 00:06:52.410
Right.
00:06:52.410 --> 00:06:55.670
In these virtual times, we
are all in different locations.
00:06:55.670 --> 00:06:57.460
Please be aware of your surroundings
00:06:57.460 --> 00:07:00.740
and have two evacuation
routes out from your location.
00:07:00.740 --> 00:07:03.090
If you're alone and you
feel comfortable doing so,
00:07:03.090 --> 00:07:05.130
please make sure someone
is aware of your location
00:07:05.130 --> 00:07:07.090
in the events of an emergency.
00:07:07.090 --> 00:07:09.380
These workshops are all day and require us
00:07:09.380 --> 00:07:11.100
to sit in front of a computer.
00:07:11.100 --> 00:07:12.300
We have built in breaks,
00:07:12.300 --> 00:07:15.080
but please be sure to move
around throughout the day.
00:07:15.080 --> 00:07:17.400
We also recognize the
challenge of living the lives
00:07:17.400 --> 00:07:19.550
we are living, please, be
sure to do what is needed
00:07:19.550 --> 00:07:21.650
to take care of your mental health as well,
00:07:21.650 --> 00:07:24.160
including taking breaks as needed.
00:07:24.160 --> 00:07:27.220
Please practice public health
guidance regarding COVID-19
00:07:27.220 --> 00:07:29.160
if you were around the people.
00:07:29.160 --> 00:07:31.680
And finally, if you feel
something, say something,
00:07:31.680 --> 00:07:33.510
if you need immediate assistance
00:07:33.510 --> 00:07:35.440
in addition to someone knowing your location,
00:07:35.440 --> 00:07:37.840
you're welcome to say
so in the chat function.
00:07:37.840 --> 00:07:40.790
We will be monitoring the
chat function throughout the day.
00:07:42.340 --> 00:07:43.960
So moving on to slide two
00:07:45.980 --> 00:07:48.837
I'll take a moment to go
over the schedule for today.
00:07:48.837 --> 00:07:51.510
The general cadence of the workshop is
00:07:51.510 --> 00:07:54.110
to allow periods of time
for each utility to present
00:07:54.110 --> 00:07:57.710
on the design and to present
on the designated topic,
00:07:57.710 --> 00:07:59.760
then take a break, and then answering
00:07:59.760 --> 00:08:01.453
to a question and answer session.
00:08:02.680 --> 00:08:05.090
First step today is risk assessment, mapping,
00:08:05.090 --> 00:08:07.640
and resource allocation methodology.
00:08:07.640 --> 00:08:12.000
After a break, we will begin
our Q&A session on that topic.
00:08:12.000 --> 00:08:15.730
Next will be lunch, followed
by utility presentations
00:08:15.730 --> 00:08:17.293
on vegetation management.
00:08:18.570 --> 00:08:20.010
We will then take another break
00:08:20.010 --> 00:08:22.420
and then into our Q&A on that topic.
00:08:22.420 --> 00:08:25.220
We will end the day with a
brief wrap-up and next steps.
00:08:26.620 --> 00:08:28.383
Just moving on to the third slide.
00:08:31.440 --> 00:08:34.833
In framing our discussion
over the next two days,
00:08:35.720 --> 00:08:38.080
sorry, in framing our discussion today,
00:08:38.080 --> 00:08:39.950
the Wildfire Safety Division asks you
00:08:39.950 --> 00:08:44.260
to focus on each of the
four questions listed below.
00:08:44.260 --> 00:08:46.300
So firstly, what progress have you achieved
00:08:46.300 --> 00:08:48.340
over the past year and how does
00:08:48.340 --> 00:08:52.313
that progress impact anticipated
work in 2021 and 2022?
00:08:53.180 --> 00:08:54.860
How do you understand your best and
00:08:54.860 --> 00:08:58.230
how does risk factor into decision-making?
00:08:58.230 --> 00:08:59.770
Here we want to emphasize that each
00:08:59.770 --> 00:09:02.170
of the mitigation initiatives
should be prioritized
00:09:02.170 --> 00:09:04.719
based on their reduction of wildfire ignition
00:09:04.719 --> 00:09:06.950
and the energization event.
00:09:06.950 --> 00:09:09.490
It's imperative that the
utilities moved towards a model
00:09:09.490 --> 00:09:11.470
where mitigation activities are justified
00:09:11.470 --> 00:09:14.713
and risk reduction can
be modeled and quantified.
00:09:15.630 --> 00:09:18.340
Thirdly, what's your
priority mitigation activities
00:09:18.340 --> 00:09:19.410
in the next year
00:09:19.410 --> 00:09:21.980
and where are these
activities being targeted?
00:09:21.980 --> 00:09:23.870
Is this based on risk modeling?
00:09:23.870 --> 00:09:25.920
What is the anticipated reduction in risk
00:09:25.920 --> 00:09:27.633
as a result of these actions?
00:09:28.700 --> 00:09:31.007
And this last question, sentence around PSPS
00:09:31.007 --> 00:09:33.300
or the energization events.
00:09:33.300 --> 00:09:35.960
So how will initiatives
reduce the risk of ignition,
00:09:35.960 --> 00:09:40.400
wildfire spread, and impact
to the decision to use PSPS?
00:09:40.400 --> 00:09:42.240
This last question is embedded
00:09:42.240 --> 00:09:43.730
in the previous three questions
00:09:43.730 --> 00:09:47.552
and is not discussed as a separate item here.
00:09:47.552 --> 00:09:49.250
Before I hand it over to our moderator
00:09:49.250 --> 00:09:51.960
to the first portion of the workshop,
00:09:51.960 --> 00:09:54.517
I'll go over a few meeting logistics.
00:09:55.677 --> 00:09:57.427
So just switched to the next slide.
00:09:59.790 --> 00:10:00.780
Thanks.
00:10:00.780 --> 00:10:03.410
So most participants are in listen only mode.
00:10:03.410 --> 00:10:05.980
That means you cannot
speak, but you are still welcome
00:10:05.980 --> 00:10:09.200
to interact and ask questions
using the chat feature.
00:10:09.200 --> 00:10:11.113
Do you do not use the Q&A feature.
00:10:12.030 --> 00:10:14.070
The chat and the Q&A tools are
00:10:14.070 --> 00:10:17.610
in the lower right-hand
corner of the WebEx screen.
00:10:17.610 --> 00:10:19.330
Again, only use the chat feature
00:10:19.330 --> 00:10:21.240
to ask technical questions.
00:10:21.240 --> 00:10:24.210
It designated WebEx
host is a technical resource
00:10:24.210 --> 00:10:27.480
and is not a member of
the Wildfire Safety Division.
00:10:27.480 --> 00:10:29.210
Please only direct the chat message
00:10:29.210 --> 00:10:31.703
to the host to resolve the technical issue.
00:10:32.650 --> 00:10:34.140
If you wish to ask questions,
00:10:34.140 --> 00:10:38.050
please select all panelists
in the chat function.
00:10:38.050 --> 00:10:39.800
And one from the Wildfire Safety Division
00:10:39.800 --> 00:10:41.050
will be monitoring posts.
00:10:42.320 --> 00:10:44.220
Again, please don't use the Q&A feature.
00:10:44.220 --> 00:10:45.660
We will not be monitoring that.
00:10:45.660 --> 00:10:48.443
We will route questions
as appropriate to panelists.
00:10:50.390 --> 00:10:53.820
Finally, we have asked several
stakeholder organizations
00:10:53.820 --> 00:10:54.810
to serve as panelists.
00:10:54.810 --> 00:10:56.200
They will be given an opportunity
00:10:56.200 --> 00:10:58.493
to ask questions directly to the utility.
00:11:01.340 --> 00:11:03.190
You can just click to the next slide.
00:11:06.200 --> 00:11:09.400
As an example, in the Q&A
during the risk assessment
00:11:09.400 --> 00:11:11.533
and mapping section, stakeholders designates
00:11:11.533 --> 00:11:14.280
that panelists may use
the raise hand function
00:11:14.280 --> 00:11:16.150
in order to ask questions.
00:11:16.150 --> 00:11:19.150
The moderator will
coordinate those questions.
00:11:19.150 --> 00:11:21.480
Everyone else, please use the chat function
00:11:21.480 --> 00:11:23.030
as described earlier.
00:11:24.230 --> 00:11:26.150
Depending on the number
of questions received,
00:11:26.150 --> 00:11:27.930
we may not be able to cover all of them,
00:11:27.930 --> 00:11:31.480
but we'll do our best, right?
00:11:31.480 --> 00:11:34.920
And with that, I'll
hand it over to Alan Wu
00:11:34.920 --> 00:11:38.390
to moderate our third
portion of today's workshop.
00:11:38.390 --> 00:11:39.223
Alan.
00:11:42.860 --> 00:11:45.373
Hi, thank you for the introduction, Lucy.
00:11:46.760 --> 00:11:47.593
Hi, everyone.
00:11:47.593 --> 00:11:48.670
Good morning.
00:11:48.670 --> 00:11:51.540
My name is Alan Wu, and
I'm a wildfire safety analyst
00:11:51.540 --> 00:11:54.930
with the mitigation branch
of the Wildfire Safety Division.
00:11:54.930 --> 00:11:57.330
I'll be your moderator
for the upcoming session.
00:11:58.370 --> 00:12:02.140
Wildfires continue to be a
big threat to the environmental,
00:12:02.140 --> 00:12:04.110
social, and economical well-being
00:12:04.110 --> 00:12:07.570
for the State of
California and wildfire risks
00:12:07.570 --> 00:12:10.420
or wildfire risk models
will play an important part
00:12:10.420 --> 00:12:12.650
of the battle by being the thread
00:12:12.650 --> 00:12:15.193
that holds the WMP together.
00:12:16.250 --> 00:12:18.510
Risk models should show the utilities
00:12:18.510 --> 00:12:21.800
where their risks lie now,
where the risks will be
00:12:21.800 --> 00:12:25.700
in the future, and also
act as a guiding compass
00:12:25.700 --> 00:12:28.693
to pinpoint where resources
should be distributed.
00:12:30.470 --> 00:12:34.520
For the next 45 minutes, we
will focus on risk assessment,
00:12:34.520 --> 00:12:38.320
mapping, and resource allocation methodology.
00:12:38.320 --> 00:12:41.920
The three SMJU utility
companies will describe
00:12:41.920 --> 00:12:45.170
their risk modeling
efforts, but more specifically
00:12:45.170 --> 00:12:48.690
how the models have
progressed since the 2020 WMP
00:12:48.690 --> 00:12:51.750
and how the utility company
incorporates risk models
00:12:51.750 --> 00:12:53.860
with decision-making.
00:12:53.860 --> 00:12:55.380
We will present in the order
00:12:55.380 --> 00:12:58.850
of PacifiCorp Liberty and Bear Valley.
00:12:58.850 --> 00:13:01.147
Members of the panel,
please reserve all questions
00:13:01.147 --> 00:13:04.640
for the Q&A session and
members of the audience feel free
00:13:04.640 --> 00:13:07.660
to submit questions via chat
throughout the presentation
00:13:07.660 --> 00:13:10.340
and Coco Tumasyan, our chat moderator,
00:13:10.340 --> 00:13:13.100
will read them during the Q&A session.
00:13:13.100 --> 00:13:15.220
All right, PacifiCorp, we'll start with you.
00:13:15.220 --> 00:13:16.053
Thank you.
00:13:22.040 --> 00:13:22.873
Good morning.
00:13:22.873 --> 00:13:23.706
This is Heidi Caswell.
00:13:24.788 --> 00:13:28.003
I don't know if you're going
to bring up the slide deck.
00:13:31.420 --> 00:13:33.290
Can we bring up the slide deck?
00:13:33.290 --> 00:13:34.830
Yeah.
00:13:34.830 --> 00:13:35.963
What's the name of it?
00:13:36.875 --> 00:13:37.958
PacifiCorp.
00:13:44.620 --> 00:13:47.453
It's the one with risk
at the end of the title.
00:13:51.660 --> 00:13:52.880
Thank you.
00:13:52.880 --> 00:13:54.023
So good morning.
00:13:55.050 --> 00:13:56.683
My name is Heidi Caswell.
00:13:57.850 --> 00:14:00.080
I'm the Director of T&D Asset Performance
00:14:00.080 --> 00:14:02.760
and Wildfire Mitigation at PacifiCorp.
00:14:03.970 --> 00:14:05.180
And I'd like to discuss
00:14:07.870 --> 00:14:12.023
how we have moved forward
with our risk assessment process.
00:14:13.980 --> 00:14:16.070
I'll try to tie it to the specifics
00:14:16.070 --> 00:14:19.840
around the risk mapping activity
00:14:19.840 --> 00:14:24.840
as well as locational
identification of risks,
00:14:26.480 --> 00:14:29.380
as well as then tying it
to the specific initiative
00:14:31.490 --> 00:14:33.263
that reduce that risk.
00:14:35.479 --> 00:14:38.960
There's some kind of feedback
going on with my phone.
00:14:38.960 --> 00:14:40.933
So I don't-- That was me.
00:14:40.933 --> 00:14:41.860
I'm going on mute.
00:14:41.860 --> 00:14:42.693
I apologize.
00:14:47.160 --> 00:14:47.993
Thank you.
00:14:50.160 --> 00:14:51.243
So next slide.
00:14:54.190 --> 00:14:56.790
So PacifiCorp has made substantial progress
00:14:56.790 --> 00:14:59.420
in our risk assessment methodology
00:14:59.420 --> 00:15:03.713
as pointed out in our 2020 feedback,
00:15:05.020 --> 00:15:09.460
the feedback received from 2020 WMP.
00:15:09.460 --> 00:15:12.790
We were fairly focused on the use
00:15:12.790 --> 00:15:17.130
of the high fire threat
district and the various tiers
00:15:17.130 --> 00:15:21.330
and we're inspired to really advance
00:15:22.190 --> 00:15:27.190
how we looked at locational
risk, like many peer utilities,
00:15:27.870 --> 00:15:30.730
especially those that discuss their processes
00:15:30.730 --> 00:15:35.500
through the large three
investor owned utilities.
00:15:35.500 --> 00:15:38.770
We've been using a lot of
data science, machine learning,
00:15:38.770 --> 00:15:41.960
and other kind of more advanced techniques
00:15:41.960 --> 00:15:46.300
to try and model the risk
00:15:46.300 --> 00:15:49.110
with data sets that we have,
00:15:49.110 --> 00:15:52.740
incorporate datasets that
previously we haven't incorporated
00:15:54.085 --> 00:15:59.085
and then try to extend
that into kind of the what if
00:15:59.860 --> 00:16:02.310
to be able to then serve against
00:16:03.610 --> 00:16:06.770
as an input to selecting
mitigation initiatives
00:16:06.770 --> 00:16:08.583
and prioritizing around those.
00:16:09.440 --> 00:16:14.440
Again, previously, we were
applying the designation
00:16:15.130 --> 00:16:16.910
of the high fire threat district
00:16:18.020 --> 00:16:22.160
as a indicator of should this circuit
00:16:22.160 --> 00:16:26.170
or these customer served by
the circuit be part of elevated
00:16:27.180 --> 00:16:30.930
and more highly
prioritized activities or not.
00:16:30.930 --> 00:16:35.930
And with this update, we've
made some substantial strides
00:16:36.400 --> 00:16:39.193
to advance beyond that.
00:16:40.220 --> 00:16:43.340
We also previously looked at seasonal impact
00:16:43.340 --> 00:16:45.350
of ignition probability
00:16:45.350 --> 00:16:48.203
and had less focus on risk event drivers.
00:16:49.090 --> 00:16:53.830
In other words, we looked
at unplanned outages
00:16:53.830 --> 00:16:57.610
of very similar risks and
with this update have tried
00:16:57.610 --> 00:17:02.070
to really align more
specifically against specific types
00:17:02.070 --> 00:17:07.070
of risk events and
understand the why, the when,
00:17:08.930 --> 00:17:11.390
the how, the where kind of aspect
00:17:12.680 --> 00:17:15.593
to working against them.
00:17:17.232 --> 00:17:21.140
As one of the large elements incorporated
00:17:21.140 --> 00:17:24.600
into our risk assessment, we
look at the vegetation canopy
00:17:24.600 --> 00:17:29.230
as well at a zonal level and we quantify
00:17:29.230 --> 00:17:30.760
what we call utility risk,
00:17:30.760 --> 00:17:34.260
which is the result of
those unplanned outages,
00:17:34.260 --> 00:17:37.270
vegetation exposure, recorded history,
00:17:37.270 --> 00:17:42.270
and then a probabilistic
arc energy calculation.
00:17:42.690 --> 00:17:46.280
In the future, we anticipate
looking at elements
00:17:46.280 --> 00:17:50.070
such as equipment types,
some specific components
00:17:50.070 --> 00:17:54.720
that may be more prone to
that catastrophic failure mode,
00:17:54.720 --> 00:17:57.550
as well as aspects around asset health
00:17:57.550 --> 00:18:01.100
and getting better precision and granularity
00:18:01.100 --> 00:18:04.490
about some of the other
inputs like vegetation.
00:18:04.490 --> 00:18:05.793
Next slide.
00:18:08.430 --> 00:18:12.740
This graphic is trying to
illustrate for you the concept
00:18:12.740 --> 00:18:15.390
that's behind our risk assessment model,
00:18:15.390 --> 00:18:19.030
which we've called the
localized risk assessment model,
00:18:19.030 --> 00:18:21.007
LRAM, in our WMT.
00:18:22.756 --> 00:18:25.710
And you can see, I've tried to make sure
00:18:25.710 --> 00:18:29.930
that you can link the different
graphics back to the WMP
00:18:29.930 --> 00:18:32.410
so that there's good reference.
00:18:32.410 --> 00:18:36.320
Some of these are I-tests
and I apologize for that.
00:18:36.320 --> 00:18:38.730
This graphic is showing you
00:18:38.730 --> 00:18:43.300
that what we take is the
basic service territory maps,
00:18:43.300 --> 00:18:47.290
so terrain and land basis behind it.
00:18:47.290 --> 00:18:51.120
We overlay on top of
that, our circuit topology,
00:18:51.120 --> 00:18:53.700
we consider the historic fire
00:18:53.700 --> 00:18:56.120
weather risk fire spread risks.
00:18:56.120 --> 00:19:00.350
So that would be as expressed
in the past development
00:19:01.200 --> 00:19:06.200
of the HFTD, the
integrated utility threat index.
00:19:07.110 --> 00:19:11.610
We overlay our tree
canopy risk modeling results
00:19:11.610 --> 00:19:15.690
from arc energy calculations
done through our sign modeling,
00:19:15.690 --> 00:19:17.850
utility ignition fault risks,
00:19:17.850 --> 00:19:22.150
so those are the unplanned
outages, and utility fires
00:19:22.150 --> 00:19:25.320
and equipment that comes
from the fire database
00:19:25.320 --> 00:19:26.990
and then fire weather risk,
00:19:26.990 --> 00:19:31.150
which is a more contemporary view
00:19:33.000 --> 00:19:34.560
around fire weather.
00:19:34.560 --> 00:19:39.310
So the last four years at a
more tightly gritted value.
00:19:39.310 --> 00:19:43.680
So that forms for us both a
long-term view and a recent view
00:19:43.680 --> 00:19:48.590
with the topology and
with the characteristics
00:19:48.590 --> 00:19:52.870
and performance that have
recently been experienced
00:19:52.870 --> 00:19:55.820
within each of those circuits of segments.
00:19:55.820 --> 00:20:00.820
And a zone of protection,
that core that we're considering,
00:20:00.920 --> 00:20:04.940
the modelable core, is
from an isolation point
00:20:04.940 --> 00:20:07.310
like a fuse or breaker recloser,
00:20:07.310 --> 00:20:10.940
that kind of device to the next downstream.
00:20:10.940 --> 00:20:15.610
So all of the conductor and
the equipment elements that are
00:20:15.610 --> 00:20:20.180
within that protective zone
are considered when ZOP
00:20:20.180 --> 00:20:24.940
for modeling purposes and
that's how we are then quantifying
00:20:26.180 --> 00:20:28.960
and calculating various aspects
00:20:31.070 --> 00:20:32.363
along that segment.
00:20:33.390 --> 00:20:37.813
Within the state, we have, if
my memory serves right, 2,700
00:20:38.900 --> 00:20:43.610
or so zones of protection,
where we have 70 some circuits.
00:20:43.610 --> 00:20:48.430
So just to help you
understand the segmentation
00:20:48.430 --> 00:20:49.303
that's going on.
00:20:50.870 --> 00:20:55.210
The next graphic actually
depicts the model results
00:20:55.210 --> 00:20:58.710
as of our most recent model run and
00:21:01.410 --> 00:21:03.600
this is for illustrative purposes,
00:21:03.600 --> 00:21:05.363
it's really is a model output.
00:21:06.290 --> 00:21:08.120
If you look at this graphic,
00:21:08.120 --> 00:21:13.000
the combined fire risk
is expressed by the width
00:21:13.000 --> 00:21:16.210
and the intensity, the darkness of the blue.
00:21:16.210 --> 00:21:18.190
So if you see certain areas
00:21:18.190 --> 00:21:21.780
where there are very lightly revealed blue
00:21:21.780 --> 00:21:22.990
and not very thick,
00:21:22.990 --> 00:21:27.380
that would be the lower
combined fire risk area
00:21:28.720 --> 00:21:32.830
and the corollary to that
is the areas that are thicker
00:21:32.830 --> 00:21:36.320
and darker are the ones
that are the higher fire risk.
00:21:36.320 --> 00:21:39.140
And again, this is the combination
00:21:39.140 --> 00:21:42.240
of what we call the utility risk blended
00:21:42.240 --> 00:21:44.223
with the climate impact.
00:21:46.053 --> 00:21:49.780
So it has that consideration of vegetation,
00:21:49.780 --> 00:21:52.060
outage performance, arc energy,
00:21:52.060 --> 00:21:54.643
and then the climatology in the area.
00:21:56.370 --> 00:21:58.540
The next graphic
00:21:58.540 --> 00:22:00.710
or next slide if you wouldn't mind.
00:22:00.710 --> 00:22:02.970
I wanted to actually walk through the process
00:22:02.970 --> 00:22:06.930
that we went through so
that that map maybe starts
00:22:06.930 --> 00:22:09.090
to make a little bit more
sense of that model,
00:22:09.090 --> 00:22:11.010
output makes a little more sense.
00:22:11.010 --> 00:22:14.880
And it really is a five step process.
00:22:14.880 --> 00:22:17.910
We look at our outage data and analyze it,
00:22:17.910 --> 00:22:20.923
categorize it to look
at that risk event driver.
00:22:21.840 --> 00:22:24.970
We then look at risk
events by the probability
00:22:26.568 --> 00:22:31.568
and we also then look at fire records
00:22:32.660 --> 00:22:35.623
against the risk event drivers.
00:22:36.800 --> 00:22:39.760
Then the next step is
to look at the initiatives
00:22:39.760 --> 00:22:43.470
that target against
specific risk event drivers
00:22:43.470 --> 00:22:47.630
and then prioritize those
mitigation efforts using a variety
00:22:48.826 --> 00:22:53.610
of measures, including
customers impacted combined risk,
00:22:53.610 --> 00:22:55.930
utility risk, and so it's kind of
00:22:55.930 --> 00:23:00.930
like a multi-dimensional view
that happens at the very end.
00:23:02.460 --> 00:23:05.190
So this first graphic shows you
00:23:05.190 --> 00:23:09.520
how we map our outage cause code data
00:23:09.520 --> 00:23:13.380
and some of the data
mining that we have to do
00:23:13.380 --> 00:23:16.330
within those records in order to align them
00:23:16.330 --> 00:23:21.330
against the risk events and the drivers.
00:23:21.450 --> 00:23:23.680
So we've got contact from object,
00:23:23.680 --> 00:23:26.470
we've got equipment failure,
we've got some unknown,
00:23:26.470 --> 00:23:28.480
some human errors, all of those.
00:23:28.480 --> 00:23:33.380
And we basically repurpose
what would be traditional
00:23:35.294 --> 00:23:38.450
categorization of our outage causes
00:23:38.450 --> 00:23:43.450
in order to align against the risk events
00:23:43.540 --> 00:23:47.143
that are relative to fire risks.
00:23:48.783 --> 00:23:53.210
And the next slide, we then look at
00:23:53.210 --> 00:23:56.440
on the number two shows you
00:23:56.440 --> 00:23:59.113
where we analyze it by cause category.
00:24:00.070 --> 00:24:05.070
And you can see that 42% of
the risk events during the 2015
00:24:06.700 --> 00:24:11.300
through 2020 fire season
time period are the result
00:24:11.300 --> 00:24:14.780
of equipment failure, and 22%
00:24:16.690 --> 00:24:20.950
of the total is associated
with contact from object.
00:24:20.950 --> 00:24:23.300
It's important for me to note that sometimes
00:24:23.300 --> 00:24:26.420
in equipment failure, it's actually a contact
00:24:26.420 --> 00:24:28.660
from an object that
causes an equipment failure
00:24:28.660 --> 00:24:32.340
like a tree branch breaks something.
00:24:32.340 --> 00:24:35.210
And so we attempt to separate that,
00:24:35.210 --> 00:24:37.810
but recognize there can
be a little bit of fuzziness
00:24:38.650 --> 00:24:42.723
within that big blue wedge of the pie.
00:24:45.000 --> 00:24:49.000
In the pie chart that's
designated number three,
00:24:49.000 --> 00:24:53.700
we take the fire utility fire database
00:24:53.700 --> 00:24:58.700
and go backwards with that
and see that 47% of the fires,
00:25:00.380 --> 00:25:03.770
and it is a sparse dataset,
but 40% of the fires
00:25:03.770 --> 00:25:07.930
that we've record of are
associated with equipment failure
00:25:07.930 --> 00:25:11.760
while 41% of them are associated
with contact from objects.
00:25:11.760 --> 00:25:16.760
So those two continue to
kind of stand out as the areas
00:25:18.970 --> 00:25:23.970
to be responsive to and
while not part of our WMP,
00:25:24.620 --> 00:25:28.993
we were asked to actually
score the risk events.
00:25:31.430 --> 00:25:35.540
And so that's actually on
the right side we identify
00:25:35.540 --> 00:25:40.170
during fire season and
non-fire season the high,
00:25:40.170 --> 00:25:44.990
medium high, medium,
medium low, and low values
00:25:44.990 --> 00:25:48.210
for each of those risk event drivers
00:25:48.210 --> 00:25:51.083
versus the fire risk expectations.
00:25:55.300 --> 00:26:00.300
On the next slide, we try to align again,
00:26:01.150 --> 00:26:03.490
back against the risk event driver,
00:26:03.490 --> 00:26:07.240
the different mitigations that are part
00:26:07.240 --> 00:26:10.190
of our thought process
when we're looking at them.
00:26:10.190 --> 00:26:13.150
And this is actually in the WMT, it shows up
00:26:13.150 --> 00:26:16.310
as three separate tables
just to make it readable
00:26:16.310 --> 00:26:19.550
in the documents and
the first series are focused
00:26:19.550 --> 00:26:22.430
around the arc energy conductor damage,
00:26:22.430 --> 00:26:25.100
and then the equipment failure piece,
00:26:25.100 --> 00:26:27.613
and then the asset hardening piece,
00:26:29.280 --> 00:26:33.120
and, sorry, equipment failure
and vegetation management.
00:26:33.120 --> 00:26:38.120
So what you can see is that hopefully,
00:26:38.330 --> 00:26:40.690
if there's an X in the box, it indicates
00:26:43.330 --> 00:26:46.180
that that mitigation measure can be effective
00:26:46.180 --> 00:26:48.240
against that risk event driver.
00:26:48.240 --> 00:26:51.520
So when you would look at, as an example,
00:26:51.520 --> 00:26:55.190
the animal contact has several ways
00:26:55.190 --> 00:26:58.340
that animal contact can be mitigated against.
00:26:58.340 --> 00:27:03.340
It can be improved by
coordinating protective equipment
00:27:04.200 --> 00:27:08.060
by additional protective equipment,
00:27:08.060 --> 00:27:10.980
by a variety of hardening activities
00:27:10.980 --> 00:27:13.910
that are over on the right
side of the table and such.
00:27:13.910 --> 00:27:18.910
But that's really to try
and identify for individuals
00:27:19.770 --> 00:27:23.090
that we don't have a
one size fits all solution
00:27:23.090 --> 00:27:24.370
for how you might mitigate
00:27:24.370 --> 00:27:27.270
and it really is very
targeted against the specific.
00:27:27.270 --> 00:27:31.000
So there's, as you can
see here, animal guarding,
00:27:31.000 --> 00:27:32.773
spreading the construction,
00:27:34.350 --> 00:27:36.373
enhancing the installation,
00:27:37.380 --> 00:27:40.320
covering conductor, all of those are possible
00:27:40.320 --> 00:27:45.320
for animals contact, which
again is contact from object
00:27:45.900 --> 00:27:47.660
under the risk event driver.
00:27:47.660 --> 00:27:50.640
So that's how we look at the initiative
00:27:50.640 --> 00:27:53.160
in order to understand what kind
00:27:53.160 --> 00:27:57.867
of solutions might
resolve that specific driver.
00:28:03.320 --> 00:28:04.693
On the next slide,
00:28:08.538 --> 00:28:12.160
the focus here is on prioritization.
00:28:12.160 --> 00:28:17.160
So once we understand that there is a risk
00:28:18.650 --> 00:28:20.610
and what the elements of risk are,
00:28:20.610 --> 00:28:23.270
so when we see the zone of protection,
00:28:23.270 --> 00:28:26.713
we can understand is it a
vegetation contact issue,
00:28:27.940 --> 00:28:32.090
is it history around a
specific type of outages,
00:28:32.090 --> 00:28:35.880
what is the probability of
any kind of arc energy issue
00:28:35.880 --> 00:28:37.940
if a fault event were to occur?
00:28:37.940 --> 00:28:41.670
We then are given the
ability to see the zones
00:28:41.670 --> 00:28:44.190
of protection within each of the circuits.
00:28:44.190 --> 00:28:48.913
And in that case, in the
upper left chart, which is shown
00:28:51.390 --> 00:28:55.163
on page 75 in our WMP the figure 45-14.
00:28:57.170 --> 00:29:01.100
This actually shows you in
kind of a histogram sort of view
00:29:02.360 --> 00:29:05.440
against the combined
score, which is the expression
00:29:05.440 --> 00:29:09.780
of the combination of
utility and climate risk,
00:29:09.780 --> 00:29:14.140
each of the zones of protection performance
00:29:15.240 --> 00:29:16.390
for every circuit.
00:29:16.390 --> 00:29:19.390
So you can see that there
are a couple of circuits
00:29:19.390 --> 00:29:22.580
that have kind of some
outliers zones of protection,
00:29:22.580 --> 00:29:27.580
which then would mean that
in order to improve fire risk
00:29:29.983 --> 00:29:34.700
as well as possible, you
would attack those specific ones.
00:29:34.700 --> 00:29:37.180
You can also see that
there are certain circuits
00:29:37.180 --> 00:29:40.520
that have very similar
characteristics for the zones
00:29:40.520 --> 00:29:42.797
of protection, which then would suggest that
00:29:42.797 --> 00:29:46.340
since they are at perhaps an elevated level,
00:29:46.340 --> 00:29:51.340
all of that particular circuit
is worthy of quick reaction
00:29:52.940 --> 00:29:54.683
from the mitigation perspective.
00:29:56.010 --> 00:30:01.010
The next chart to the right
looks at the fire weather score.
00:30:03.060 --> 00:30:07.090
So this is really the climatology
and the combined score.
00:30:07.090 --> 00:30:10.280
So that helps us understand those areas
00:30:10.280 --> 00:30:15.180
where it's not the utility risk
00:30:15.180 --> 00:30:19.460
that maybe is driving the situation,
00:30:19.460 --> 00:30:21.900
it's actually the location.
00:30:21.900 --> 00:30:26.900
So that helps us understand
what about it is the where.
00:30:27.140 --> 00:30:31.953
And you can see that we had circuits
00:30:31.953 --> 00:30:36.082
that had projects that were
prioritized and certain circuits
00:30:36.082 --> 00:30:39.870
that previously had not yet been prioritized
00:30:39.870 --> 00:30:43.170
for some of the mitigation measures,
00:30:43.170 --> 00:30:46.510
which were revealed
with this view of the data
00:30:46.510 --> 00:30:51.510
as opposed to the expression
of the HFTD and our PSPS plan.
00:30:53.613 --> 00:30:56.450
So it gives us another way to validate
00:30:56.450 --> 00:30:59.930
and modify the prioritization of our work
00:30:59.930 --> 00:31:03.010
now that we see it in
this, through this lens.
00:31:03.010 --> 00:31:07.660
In the upper, right, we can use that view
00:31:07.660 --> 00:31:12.610
to help us understand the combined score risk
00:31:12.610 --> 00:31:16.700
across the bottom against
the impact to customers.
00:31:16.700 --> 00:31:20.520
And what I failed to note is that the size
00:31:20.520 --> 00:31:25.320
of the bubble is the circuit length
00:31:25.320 --> 00:31:26.730
or indicates the circuit length.
00:31:26.730 --> 00:31:30.973
So a small bubble is a short circuit,
00:31:31.920 --> 00:31:36.660
short in length circuit,
whereas a larger bubble is one
00:31:36.660 --> 00:31:39.770
that has more circuit
mileage to be dealt with.
00:31:39.770 --> 00:31:42.820
And so we can start to
understand both the customer piece
00:31:42.820 --> 00:31:46.770
as well as then by the big or little circles
00:31:46.770 --> 00:31:49.810
how exhaustive our efforts would need
00:31:49.810 --> 00:31:54.810
to be versus the risk that
we would be buying down
00:31:54.990 --> 00:31:57.113
essentially with the mitigation efforts.
00:32:00.170 --> 00:32:05.170
So there were a variety of
other ways that we also look
00:32:06.530 --> 00:32:11.530
at kind of the alignment
of our mitigation measures
00:32:12.610 --> 00:32:15.530
against the sections of circuits
00:32:15.530 --> 00:32:18.940
within our service territory.
00:32:18.940 --> 00:32:23.940
And those are also expressed
further in the section 4.5 0.1
00:32:25.690 --> 00:32:30.360
in the WMP, but this was just to try
00:32:30.360 --> 00:32:35.030
and help work you through
that thought process.
00:32:35.030 --> 00:32:37.730
And later on, we'll talk a little bit,
00:32:37.730 --> 00:32:41.680
or other panelists will talk
about how we apply this
00:32:45.626 --> 00:32:50.626
to the asset mitigation and
vegetation management activities
00:32:50.900 --> 00:32:54.903
that are also important
parts of delivering the WMP.
00:33:00.810 --> 00:33:02.470
And Heidi, this is Alan,
00:33:02.470 --> 00:33:04.640
we do have to be aware of the time.
00:33:04.640 --> 00:33:06.083
So two minute warning here.
00:33:07.626 --> 00:33:11.130
I'm actually, if you go to the next slide,
00:33:11.130 --> 00:33:13.630
I can say thank you and
give you back two minutes.
00:33:15.770 --> 00:33:17.353
Sorry, I just talk fast.
00:33:19.630 --> 00:33:20.560
Thank you so much, Heidi.
00:33:20.560 --> 00:33:25.560
And so next, we're going to
have Liberty Utilities present.
00:33:26.570 --> 00:33:27.403
Thank you.
00:33:38.260 --> 00:33:41.660
All right, do a short introduction here.
00:33:41.660 --> 00:33:45.800
My name's Greg Campbell,
and I'm a senior analyst
00:33:45.800 --> 00:33:50.010
in our regulatory affairs
division, and I'm here to talk
00:33:50.010 --> 00:33:52.950
about Liberty's risk assessment, mapping,
00:33:52.950 --> 00:33:57.200
and resource allocation methodology.
00:33:57.200 --> 00:33:58.053
Okay, next slide.
00:34:05.010 --> 00:34:10.010
So our progress from the
2020 WMP toward 2021 WMP
00:34:12.080 --> 00:34:14.860
of Liberty has made some significant strides
00:34:15.840 --> 00:34:20.840
and coming into 2021
Liberty was the only utility
00:34:22.150 --> 00:34:26.390
who had not filed a risk-based
decision-making framework
00:34:26.390 --> 00:34:28.770
as part of its GRC filing
00:34:28.770 --> 00:34:32.403
and this includes how
Liberty evaluates wildfire risks.
00:34:34.070 --> 00:34:38.960
So our first generation wildfire risk models
00:34:38.960 --> 00:34:43.770
were completed February 20 of 21.
00:34:43.770 --> 00:34:47.400
So and this is adopted the same approach
00:34:47.400 --> 00:34:52.400
as what the larger IOU used in their MAVF
00:34:52.930 --> 00:34:56.283
in MARS risk assessment methodology.
00:34:57.850 --> 00:35:00.050
And so we used this approach
00:35:00.050 --> 00:35:03.730
and this approach replaced our old approach,
00:35:03.730 --> 00:35:07.330
which mainly consisted of qualitative scoring
00:35:07.330 --> 00:35:08.743
and using heat maps.
00:35:09.780 --> 00:35:11.180
So these were some techniques
00:35:11.180 --> 00:35:13.950
that the Commission expressed some preference
00:35:13.950 --> 00:35:15.280
to move away from
00:35:15.280 --> 00:35:18.320
and to incorporate more quantitative analysis
00:35:18.320 --> 00:35:20.023
and that's what Liberty has done.
00:35:21.659 --> 00:35:26.220
So the company we've established
a risk mapping capabilities
00:35:26.220 --> 00:35:29.333
through our partnership
with Reax Engineering.
00:35:30.220 --> 00:35:33.640
And what we've been able
to do is combine that analysis
00:35:33.640 --> 00:35:37.590
that we worked with Reax
with tools like Hexagon
00:35:37.590 --> 00:35:41.650
and Power BI to complete Liberty's analysis.
00:35:41.650 --> 00:35:43.183
Okay, next slide.
00:35:46.220 --> 00:35:51.220
So prior to Liberty having
this risk mapping capability,
00:35:51.780 --> 00:35:54.031
a lot of our decisions were made
00:35:54.031 --> 00:35:57.590
on whether something was cyclical
00:35:57.590 --> 00:36:01.153
or whether something was compliance-based.
00:36:02.240 --> 00:36:06.950
And another feature of the
strides that we've made is that
00:36:06.950 --> 00:36:11.930
if you look in our maturity
survey from the 2020 WMP,
00:36:11.930 --> 00:36:15.800
a lot of our answers referred
to our projections being able
00:36:15.800 --> 00:36:19.259
to look at risk at the regional level.
00:36:19.259 --> 00:36:21.940
And so what we've been able to do is the work
00:36:21.940 --> 00:36:26.070
that we've made between 2020 and 2021,
00:36:26.070 --> 00:36:30.020
we're now able to look
at risk at the circuit level
00:36:30.020 --> 00:36:34.403
and in many cases also at
the segment or the span level.
00:36:36.376 --> 00:36:39.510
So one of the other
strives that Liberty made is
00:36:39.510 --> 00:36:44.510
we've also upgraded our outage
management system responder.
00:36:45.300 --> 00:36:47.110
And what this is able to do now is
00:36:47.110 --> 00:36:49.380
to produce a specific report
00:36:49.380 --> 00:36:52.130
that's going to capture
a lot of the data points
00:36:52.130 --> 00:36:54.380
that the Commission has asked Liberty
00:36:54.380 --> 00:36:58.443
to collect with respect to wildfire risk.
00:37:01.440 --> 00:37:04.360
And again, even with some of the advancements
00:37:04.360 --> 00:37:07.630
that Liberty's made from 2020 to 2021,
00:37:07.630 --> 00:37:11.640
there still is a lot of work to be done.
00:37:11.640 --> 00:37:15.950
Again, this is just our
first crank of our models,
00:37:15.950 --> 00:37:17.960
our first results of our models,
00:37:17.960 --> 00:37:22.820
and we do plan to dedicate more resources
00:37:22.820 --> 00:37:25.933
towards our risk-based decision
making framework initiative.
00:37:27.390 --> 00:37:28.583
Okay, next slide.
00:37:34.182 --> 00:37:38.432
As we can see on this
slide, in quarter one of 2020
00:37:39.530 --> 00:37:43.310
in the six step risk-based
decision-making framework
00:37:43.310 --> 00:37:45.120
process, we were at the beginning
00:37:45.120 --> 00:37:47.300
of the risk analysis stage.
00:37:47.300 --> 00:37:51.390
So this involved us collecting data,
00:37:51.390 --> 00:37:55.480
looking at certain data
points whether it was coming
00:37:55.480 --> 00:37:58.130
from our outage management system,
00:37:58.130 --> 00:38:00.560
whether it was coming
from our inspection reports,
00:38:00.560 --> 00:38:05.560
we really hadn't organized
anything to be set into models
00:38:05.750 --> 00:38:08.783
and to be looked at and really analyze.
00:38:09.890 --> 00:38:14.890
So now in quarter 2021,
we've completed steps three
00:38:15.810 --> 00:38:19.840
and four and we are now
at the beginning of step five,
00:38:19.840 --> 00:38:23.410
which now allows Liberty to look at some
00:38:23.410 --> 00:38:26.367
of the model's outputs
in the form of the risk
00:38:26.367 --> 00:38:29.850
and inefficiencies and
start to incorporate this
00:38:29.850 --> 00:38:34.480
into discussions in terms
of what capital investment
00:38:34.480 --> 00:38:38.700
or operating and maintenance
program decisions are going
00:38:38.700 --> 00:38:40.560
to look like forward-looking.
00:38:41.970 --> 00:38:42.803
Next slide.
00:38:48.037 --> 00:38:49.300
Well, as I mentioned earlier,
00:38:49.300 --> 00:38:53.460
as part of Liberty's risk mapping efforts,
00:38:53.460 --> 00:38:56.700
Liberty Commissioned Reax Engineering
00:38:56.700 --> 00:39:00.910
and they conducted a
detailed wildfire risk analysis
00:39:00.910 --> 00:39:03.173
over our entire service territory.
00:39:04.280 --> 00:39:08.420
And as part of this analysis
that Reax conducted,
00:39:08.420 --> 00:39:12.920
they looked at a fire spread,
they looked at the number
00:39:12.920 --> 00:39:17.080
of structures that would be
impacted in the form of houses
00:39:17.080 --> 00:39:21.660
or in the form of businesses, they looked at
00:39:21.660 --> 00:39:25.000
what the cost would be to suppress the fire.
00:39:25.000 --> 00:39:30.000
And als the number of people
or the populations impacted
00:39:31.630 --> 00:39:36.630
for 33 distinct areas within
the Liberty service territory.
00:39:39.090 --> 00:39:43.270
Looking at these factors is very
important because as we see
00:39:43.270 --> 00:39:47.610
in some slides that we'll see coming up,
00:39:47.610 --> 00:39:51.630
this will feed in directly as the data points
00:39:51.630 --> 00:39:54.830
to model the consequences of the outcomes
00:39:54.830 --> 00:39:56.150
that Liberty's used
00:39:56.150 --> 00:40:00.490
in its risk-based decision-making
framework bow-ties.
00:40:00.490 --> 00:40:04.230
So we'll see a slide where
we'll see the four outcomes
00:40:04.230 --> 00:40:08.023
and how those consequence
modeling fits into that.
00:40:09.050 --> 00:40:09.913
Next slide.
00:40:14.570 --> 00:40:17.610
So here we see a visual
00:40:17.610 --> 00:40:19.840
and this is an example of the areas
00:40:19.840 --> 00:40:22.890
for which Reax looked
in our service territory
00:40:23.800 --> 00:40:27.130
and how they've segmented it off here.
00:40:27.130 --> 00:40:29.680
This is our South Lake Tahoe region
00:40:30.620 --> 00:40:33.360
and you can see that
there's four different colors
00:40:33.360 --> 00:40:36.730
in this graphic right here.
00:40:36.730 --> 00:40:39.010
So we have the red region
00:40:39.010 --> 00:40:43.450
and this is going to represent
very high wildfire risk.
00:40:43.450 --> 00:40:45.490
We have the pink region,
00:40:45.490 --> 00:40:49.450
this is going to represent
high wildfire risk.
00:40:49.450 --> 00:40:52.350
We look at the yellow region,
00:40:52.350 --> 00:40:56.250
this is going to represent
moderate wildfire risk.
00:40:56.250 --> 00:40:59.610
And then if we look
at this light blue region,
00:40:59.610 --> 00:41:03.570
this is going to represent low wildfire risk.
00:41:03.570 --> 00:41:05.850
And these green lines here,
00:41:05.850 --> 00:41:10.277
these are our primary
overhead distribution lines.
00:41:10.277 --> 00:41:13.750
And a lot of these lines
are going to criss-cross
00:41:13.750 --> 00:41:18.240
into different segmented
areas and these segment areas
00:41:18.240 --> 00:41:21.890
all have different wildfire risk profiles.
00:41:21.890 --> 00:41:24.260
So this will be important to keep in mind
00:41:24.260 --> 00:41:28.750
in the following slide when
I talk about how we look at
00:41:28.750 --> 00:41:33.750
what the wildfire risk rating
for individual circuits are.
00:41:34.890 --> 00:41:37.840
And lastly, it's important to note here
00:41:37.840 --> 00:41:41.470
that this dark red the
region, if you look off
00:41:41.470 --> 00:41:44.460
to the Eastern section of this dark red
00:41:44.460 --> 00:41:48.790
very high wildfire risk
region, this is currently
00:41:48.790 --> 00:41:52.680
what our HFPD three region is.
00:41:52.680 --> 00:41:57.680
So this very high wildfire
risk rating that Reax has found
00:41:59.610 --> 00:42:02.150
for this section in our
service territory aligns
00:42:02.150 --> 00:42:05.633
with our current HFTD three region.
00:42:07.020 --> 00:42:07.853
Next slide.
00:42:11.180 --> 00:42:15.270
So the next step, Liberty recombined
00:42:15.270 --> 00:42:19.210
our outage management system data
00:42:19.210 --> 00:42:23.460
along with our vegetation
management inspections,
00:42:23.460 --> 00:42:27.810
as well as our detailed
system survey inspections
00:42:27.810 --> 00:42:32.810
and looked at all of this data
in those segmented areas
00:42:34.030 --> 00:42:37.100
that Reax had looked at in terms of
00:42:37.100 --> 00:42:40.690
what is wildfire risk scoring was.
00:42:40.690 --> 00:42:42.880
So what we were able to do is integrate
00:42:42.880 --> 00:42:47.070
all Liberty's internal data with the ratings
00:42:47.070 --> 00:42:48.790
that Reax looked at
00:42:48.790 --> 00:42:52.023
and in which they segmented
our service territory.
00:42:53.270 --> 00:42:56.880
So why this is important is
that as I explained earlier,
00:42:56.880 --> 00:43:01.880
a lot of our circuits will be
located across two, three,
00:43:02.320 --> 00:43:07.200
sometimes four different wildfire risk areas.
00:43:10.100 --> 00:43:12.580
So some of our circuits could criss-cross
00:43:12.580 --> 00:43:15.860
into the very high, the
high, and the moderate.
00:43:15.860 --> 00:43:19.430
And what Liberty was able to do is take all
00:43:19.430 --> 00:43:21.920
of these different risks
that you see on the slide,
00:43:21.920 --> 00:43:25.200
our vegetation risk, our performance risk,
00:43:25.200 --> 00:43:27.340
and our asset condition risk.
00:43:27.340 --> 00:43:30.230
Look at each of those segments on the circuit
00:43:31.220 --> 00:43:36.220
and then roll that off into
an overall wildfire risk rating
00:43:37.070 --> 00:43:40.850
for that circuit, looking at
each of the different segments
00:43:40.850 --> 00:43:43.070
on that particular circuit.
00:43:43.070 --> 00:43:46.010
So in the WMP when we had to score
00:43:46.010 --> 00:43:47.970
and rank each of those circuits,
00:43:47.970 --> 00:43:50.920
that's the methodology that Liberty has used.
00:43:50.920 --> 00:43:54.360
We looked at the span
risk on a particular circuit
00:43:54.360 --> 00:43:57.800
and then rolled that up to the circuit level.
00:43:57.800 --> 00:43:59.333
Okay, next slide.
00:44:03.290 --> 00:44:04.760
Well, as I mentioned earlier,
00:44:04.760 --> 00:44:09.200
Liberty adopted the same MAVF MARS approach
00:44:09.200 --> 00:44:12.220
that the larger IOU have used
00:44:12.220 --> 00:44:15.310
in their risk-based
decision making framework.
00:44:15.310 --> 00:44:18.900
And here is a bow-tie and
this should look pretty familiar
00:44:18.900 --> 00:44:23.060
to everybody, where you
have your wildfire risk drivers
00:44:23.060 --> 00:44:27.650
off the left-hand side, you
have the actual risk event,
00:44:27.650 --> 00:44:31.450
in this case, it's a utility cause wildfire
00:44:31.450 --> 00:44:35.050
if you're not in the bow-tie.
00:44:35.050 --> 00:44:37.813
And then off to the right,
you have your outcomes.
00:44:38.730 --> 00:44:42.080
And in this case, Liberty worked with Reax
00:44:42.080 --> 00:44:46.310
to come up with four
distinct outcomes and each
00:44:46.310 --> 00:44:51.100
of these outcomes has three
consequences attached to them.
00:44:51.100 --> 00:44:54.450
So those consequences
were safety consequences,
00:44:54.450 --> 00:44:58.400
financial consequences,
and reliability consequences.
00:44:58.400 --> 00:45:02.170
And this should all be
pretty familiar with anyone
00:45:03.084 --> 00:45:08.084
who's worked closely with the
S-MAP and RAMP proceedings.
00:45:08.220 --> 00:45:10.500
So what we looked at was
00:45:10.500 --> 00:45:12.640
when we looked at those risk factors,
00:45:12.640 --> 00:45:17.640
when I mentioned the
structures impacted the numbers
00:45:17.790 --> 00:45:22.460
of population affected,
all of this was modeled
00:45:22.460 --> 00:45:25.620
in these consequences of the four outcomes
00:45:25.620 --> 00:45:28.153
that you see on this slide right here.
00:45:29.110 --> 00:45:33.757
So the technique was the same that we've seen
00:45:34.600 --> 00:45:38.820
with the larger areas
and that's the methodology
00:45:38.820 --> 00:45:42.280
that Liberty adopted to calculate its RSEs.
00:45:43.330 --> 00:45:47.400
And Liberty's RSEs with some of its scores
00:45:47.400 --> 00:45:52.080
for its first-generation
wildfire models along with each
00:45:52.080 --> 00:45:56.280
of those individual circuit
risk ratings can be found
00:45:56.280 --> 00:46:00.173
in attachment C in the 2021 WFP.
00:46:03.460 --> 00:46:07.940
All right, and that should
conclude our discussion.
00:46:07.940 --> 00:46:08.773
So thank you.
00:46:10.930 --> 00:46:11.820
Great.
00:46:11.820 --> 00:46:13.770
Thank you, Greg, for that presentation.
00:46:14.670 --> 00:46:18.180
Next up, we're going to
have Bear Valley Utilities
00:46:18.180 --> 00:46:20.340
and we're going to have Paul present.
00:46:20.340 --> 00:46:24.990
Thank you.
00:46:24.990 --> 00:46:25.823
Yeah, good morning.
00:46:25.823 --> 00:46:27.013
If you could put my brief up.
00:46:32.043 --> 00:46:35.680
Okay.
00:46:35.680 --> 00:46:36.513
One second.
00:46:39.040 --> 00:46:41.080
So a brief introduction.
00:46:41.080 --> 00:46:42.270
I'm Paul Marconi.
00:46:42.270 --> 00:46:45.860
I'm the President Bear Valley
Electric Service Incorporated
00:46:45.860 --> 00:46:47.980
and I'll actually be the analyst
00:46:47.980 --> 00:46:51.280
for all three presentations.
00:46:51.280 --> 00:46:52.730
Can you go to the next slide?
00:46:57.460 --> 00:47:00.943
Before I get into the risk
assessment, just a brief,
00:47:02.030 --> 00:47:05.400
if you've had a chance
to go through our plan,
00:47:05.400 --> 00:47:08.600
some of the key areas of our planet aims
00:47:08.600 --> 00:47:11.340
to tailor our actions to our community.
00:47:11.340 --> 00:47:14.503
It's a small area, 32 square miles.
00:47:15.450 --> 00:47:16.840
It's up in the mountains.
00:47:16.840 --> 00:47:20.133
As you can see from
the pictures, lots of trees,
00:47:22.890 --> 00:47:25.380
the trees get snow laid in, so they get weak,
00:47:25.380 --> 00:47:28.330
and then when the winds pick up in September,
00:47:28.330 --> 00:47:31.390
there's a potential for branches to come off
00:47:31.390 --> 00:47:33.223
and make contact with lines.
00:47:34.180 --> 00:47:38.220
So and because we're in a
generally a dry environment
00:47:38.220 --> 00:47:39.723
during that time of the year,
00:47:41.360 --> 00:47:43.593
we're in the high fire threat district.
00:47:44.920 --> 00:47:48.450
For those, with eagle eyes that people
00:47:48.450 --> 00:47:51.363
on the chairlift, that's pre pandemic, okay?
00:47:53.450 --> 00:47:57.060
Substantially, we
mitigate the risk of wildfire,
00:47:57.060 --> 00:47:58.793
that's what our planning to do.
00:48:00.670 --> 00:48:03.750
There's emergency response for restoration
00:48:03.750 --> 00:48:07.713
in wildfire events and so forth.
00:48:10.540 --> 00:48:14.160
One of the big things that I take away from,
00:48:14.160 --> 00:48:18.760
I think this is my third
technical workshop after filing
00:48:18.760 --> 00:48:23.303
our plan, is the incorporate
industry best practices.
00:48:24.570 --> 00:48:27.990
We always were in quite a
bit from each other's plans
00:48:27.990 --> 00:48:29.453
as we look at them as well.
00:48:30.370 --> 00:48:32.320
Can you go onto the next slide, please?
00:48:35.390 --> 00:48:38.120
So on the risk assessment, mapping,
00:48:38.120 --> 00:48:40.603
and resource allocation methodology,
00:48:42.380 --> 00:48:47.380
Bear Valley follows the small
multi-jurisdictional utilities
00:48:49.880 --> 00:48:51.450
process that was provided
00:48:51.450 --> 00:48:56.263
in a CPC decisions back in April of 2019.
00:48:56.263 --> 00:48:58.143
You can go to the next slide.
00:49:00.840 --> 00:49:05.323
This is basically a seven by seven matrix,
00:49:06.540 --> 00:49:09.560
frequency versus consequence
00:49:09.560 --> 00:49:13.703
or likelihood versus consequence logarithmic.
00:49:14.750 --> 00:49:19.103
Has the six step process
similar to what Liberty discussed.
00:49:21.600 --> 00:49:25.720
And you look at their various
risks, you look at mitigations
00:49:26.730 --> 00:49:31.730
and the output is a risk
spend ratio and risk reduction.
00:49:33.690 --> 00:49:38.690
This chart sort of demonstrates
what comes out of that.
00:49:41.830 --> 00:49:46.830
So on the X axis are all the mitigations
00:49:47.900 --> 00:49:49.970
and there we have alternatives too.
00:49:49.970 --> 00:49:54.550
So you'll have installing covered wire,
00:49:54.550 --> 00:49:59.280
you'll have undergrounding,
and then you can make a choice
00:49:59.280 --> 00:50:02.533
on which provides the best risk spend ratio.
00:50:04.600 --> 00:50:06.700
As you know, we've had this model
00:50:06.700 --> 00:50:11.367
in place since 2017, actually, and
00:50:14.730 --> 00:50:16.910
the X axis is just seems to grow
00:50:16.910 --> 00:50:20.293
because we add mitigation
and look at alternatives.
00:50:21.350 --> 00:50:25.870
So it gets a little
complicated, but it does give
00:50:25.870 --> 00:50:29.170
us a good sense of how
much risk do you reduce
00:50:34.070 --> 00:50:34.923
for the cost.
00:50:36.393 --> 00:50:37.843
You can go to the next slide.
00:50:45.510 --> 00:50:47.480
Okay, so that method
00:50:49.190 --> 00:50:52.660
that I discussed is a little less satisfying
00:50:52.660 --> 00:50:57.660
because it doesn't have that bow-tie,
00:50:58.210 --> 00:50:59.890
it doesn't show
00:50:59.890 --> 00:51:03.530
how different mitigations
interact with each other.
00:51:03.530 --> 00:51:06.640
And so that's probably
the least satisfying part
00:51:06.640 --> 00:51:07.573
of that model.
00:51:09.360 --> 00:51:12.490
And so as an interim measure, we developed
00:51:12.490 --> 00:51:16.590
what we call the fire
safety matrix, circuit matrix.
00:51:16.590 --> 00:51:19.680
And basically you're not expected
00:51:19.680 --> 00:51:22.310
to actually read the
lines in that spreadsheet.
00:51:22.310 --> 00:51:25.313
That's just showing you the model,
00:51:26.260 --> 00:51:29.960
but what the model does
is it lists for each circuit,
00:51:29.960 --> 00:51:32.930
it takes into account what are those things
00:51:32.930 --> 00:51:36.923
that make a circuit high-risk for wildfires?
00:51:38.920 --> 00:51:43.920
And then what are those things
that would mitigate the risk?
00:51:45.300 --> 00:51:49.513
And so those are those
colored boxes off to the right.
00:51:52.220 --> 00:51:55.330
And then finally, and this
is tracked in the matrix,
00:51:55.330 --> 00:51:58.363
but you don't get a score for these items.
00:51:59.760 --> 00:52:01.460
It's one of those things
00:52:01.460 --> 00:52:06.460
that lessen the impact of a wildfire, okay?
00:52:06.900 --> 00:52:11.403
For example, evacuation route hardening.
00:52:12.240 --> 00:52:14.360
It doesn't reduce the risk
00:52:14.360 --> 00:52:19.360
of the utility causing a
wildfire, seeing any points for it,
00:52:19.520 --> 00:52:21.220
but it's important to the community.
00:52:21.220 --> 00:52:23.180
So we wanna track it here.
00:52:23.180 --> 00:52:25.683
And this is the model
where we tracked it and so,
00:52:27.100 --> 00:52:28.760
we incorporate some of these items
00:52:28.760 --> 00:52:31.973
that are important to
just wildfires in general.
00:52:36.295 --> 00:52:40.080
So the way we apply this
model is we take the output
00:52:40.080 --> 00:52:43.783
from the previous model,
the risk spend ratios,
00:52:44.920 --> 00:52:49.580
and we decide, okay, if we
want to apply this mitigation,
00:52:49.580 --> 00:52:52.853
which circuits should we
apply to this mitigation to?
00:52:53.870 --> 00:52:56.810
And so that's where this allows us
00:52:56.810 --> 00:52:59.443
to get that granularity
down to the circuit level.
00:53:01.330 --> 00:53:04.500
And we would like, in the future,
00:53:04.500 --> 00:53:07.540
we wanna look to get even more granular,
00:53:07.540 --> 00:53:11.430
but we also tamper that
with the fact that, like I said,
00:53:11.430 --> 00:53:16.370
we're 32 square miles, so
circuits really aren't that long.
00:53:16.370 --> 00:53:18.263
And in general, many circuits,
00:53:21.890 --> 00:53:23.840
you're as granular as you're gonna get.
00:53:26.650 --> 00:53:28.890
But we wanna take a look at that
00:53:28.890 --> 00:53:31.243
as we develop our processes.
00:53:34.950 --> 00:53:36.300
You can go to the next one.
00:53:40.410 --> 00:53:43.400
So one of the things I
really like about this model is
00:53:43.400 --> 00:53:47.960
when we decide to do different mitigations,
00:53:47.960 --> 00:53:51.580
we can then fast forward and
plug them in the model and say,
00:53:51.580 --> 00:53:53.803
okay, if we apply that mitigation,
00:53:56.760 --> 00:54:00.470
what will the risk value of that circuit be?
00:54:00.470 --> 00:54:05.470
And if we look at our plan holistically
00:54:06.150 --> 00:54:08.753
and step through it at the three-year point,
00:54:09.850 --> 00:54:12.670
what's our system gonna look like?
00:54:12.670 --> 00:54:14.020
And then at the ten year point,
00:54:14.020 --> 00:54:14.853
what are we gonna look like?
00:54:14.853 --> 00:54:18.500
And you can see how there's that progression.
00:54:18.500 --> 00:54:20.690
You can also win, which is really neat,
00:54:20.690 --> 00:54:23.697
is you can play with the mitigation
00:54:23.697 --> 00:54:27.440
and we say, well, if I
only, if I install covered wire
00:54:27.440 --> 00:54:30.080
but I only need to install a certain amount
00:54:30.080 --> 00:54:31.350
on this particular circuit
00:54:31.350 --> 00:54:33.100
I already get it down to the green.
00:54:34.702 --> 00:54:39.130
So those are ways that we can prioritize
00:54:40.960 --> 00:54:45.960
or get circuits down to
medium or moderate risk
00:54:47.760 --> 00:54:50.950
and then focus on getting those
other reds down to moderate
00:54:50.950 --> 00:54:53.034
and then go onto the green.
00:54:53.034 --> 00:54:58.034
So those are some items
that the model allows us to do,
00:54:58.310 --> 00:55:01.520
allows the decision-makers determine
00:55:01.520 --> 00:55:06.063
where we're gonna put our resources.
00:55:08.800 --> 00:55:11.480
Point to note, what the algorithm does,
00:55:11.480 --> 00:55:13.900
it's really heavily
weighted towards bare wire,
00:55:13.900 --> 00:55:15.260
overhead bare wire.
00:55:15.260 --> 00:55:19.800
Okay, so one of the things that we also did
00:55:19.800 --> 00:55:20.908
in the model,
00:55:20.908 --> 00:55:25.908
we rely a lot on subject
matter experts, right?
00:55:27.250 --> 00:55:32.250
So in the early days, subject
matter expert we would say,
00:55:33.340 --> 00:55:36.423
hey, that's an area of high winds and
00:55:40.530 --> 00:55:43.470
heavy vegetation density.
00:55:43.470 --> 00:55:45.520
Now, we've quantified those things.
00:55:45.520 --> 00:55:48.270
For example, with the
weather stations dispersed
00:55:48.270 --> 00:55:51.450
throughout our service area, we can say,
00:55:51.450 --> 00:55:53.720
okay, we know what the winds are
00:55:53.720 --> 00:55:55.730
at different points on our circuits.
00:55:55.730 --> 00:55:57.970
And so, and we have history now,
00:55:57.970 --> 00:56:02.010
so we can say if the winds are less,
00:56:02.010 --> 00:56:06.240
if the highest wind are
less than 20 miles per hour
00:56:06.240 --> 00:56:07.553
on dry days,
00:56:09.610 --> 00:56:13.583
then the wind intensity is low.
00:56:14.587 --> 00:56:19.230
And we can quantify these
so that we're no longer relying
00:56:19.230 --> 00:56:21.883
on an SME to tell us, that's a windy area.
00:56:24.962 --> 00:56:26.920
And before this effort,
00:56:26.920 --> 00:56:28.880
you need to understand
the only weather station
00:56:28.880 --> 00:56:31.530
in Big Bear Lake was at the airport.
00:56:31.530 --> 00:56:33.500
Now, we have a bunch
throughout the service area,
00:56:33.500 --> 00:56:35.223
So we get very granular.
00:56:36.290 --> 00:56:37.990
The other thing is also in vegetation,
00:56:37.990 --> 00:56:40.880
same thing with the advent of putting
00:56:40.880 --> 00:56:43.970
all the trees in our GIS,
00:56:43.970 --> 00:56:48.970
we're able to quantify
the vegetation density.
00:56:49.770 --> 00:56:54.540
So for example, if on average
a span has less than 10 trees,
00:56:54.540 --> 00:56:57.270
that might be classified as low
00:56:57.270 --> 00:57:00.640
and I'm just picking some
arbitrary numbers here,
00:57:00.640 --> 00:57:02.770
10 to 20 trees would be medium
00:57:02.770 --> 00:57:05.723
and then more than 20
trees, it's high density.
00:57:06.640 --> 00:57:09.620
So those are ways that we get around
00:57:10.610 --> 00:57:15.610
not relying so much on
someone's judgment in particular,
00:57:16.170 --> 00:57:19.530
but being quantified across the Board
00:57:19.530 --> 00:57:23.473
and providing some
reasonableness to our assessments.
00:57:24.780 --> 00:57:26.013
So onto the next one.
00:57:31.120 --> 00:57:36.120
So we're a small utility and
one of the important pieces
00:57:37.080 --> 00:57:39.153
in resource allocation staff.
00:57:40.400 --> 00:57:42.823
And we did a lot of things recently,
00:57:44.000 --> 00:57:49.000
one, we rewrote a lot of the
job descriptions for people,
00:57:49.176 --> 00:57:53.270
even for people who are there
to really emphasize their role
00:57:53.270 --> 00:57:55.293
in the wildfire mitigation plans.
00:57:56.960 --> 00:58:01.960
I believe in section one,
we identify who's who
00:58:02.390 --> 00:58:06.050
and what they do in this
wildfire mitigation plan.
00:58:06.050 --> 00:58:09.870
So we wanna make sure that
works with their job description
00:58:12.157 --> 00:58:13.380
'cause personal accountability
00:58:13.380 --> 00:58:15.910
to me is absolutely essential
00:58:15.910 --> 00:58:18.990
in addition to the risk
assessments and so forth.
00:58:18.990 --> 00:58:20.680
It's also that personnel side,
00:58:20.680 --> 00:58:23.210
making sure there's true accountability
00:58:23.210 --> 00:58:25.713
by the individuals involved in the plan.
00:58:30.990 --> 00:58:32.880
In our job drivers get from roles,
00:58:32.880 --> 00:58:34.200
we have a utility engineer
00:58:34.200 --> 00:58:36.890
and wildfire mitigation supervisor,
00:58:36.890 --> 00:58:39.450
that just used to be the
engineering supervisor.
00:58:39.450 --> 00:58:44.450
Now, very specific role
in wildfire mitigation,
00:58:44.552 --> 00:58:47.160
we added a wildfire mitigation
00:58:47.160 --> 00:58:52.090
and reliability engineer
who runs all these programs
00:58:52.090 --> 00:58:54.093
and gets the data.
00:58:55.000 --> 00:58:58.320
We brought on a dedicated
project coordinator 'cause
00:59:01.190 --> 00:59:04.140
like any utility you have two functions going
00:59:04.140 --> 00:59:05.980
on at the same time,
00:59:05.980 --> 00:59:08.750
you have execution and you have planning.
00:59:08.750 --> 00:59:12.340
And in the past,
00:59:12.340 --> 00:59:14.943
Bear Valley Electric was doing both
00:59:14.943 --> 00:59:16.713
with the same group of people.
00:59:17.843 --> 00:59:20.970
And we found that we really
had to break that piece up
00:59:22.180 --> 00:59:25.270
and then we've contracted a forester
00:59:25.270 --> 00:59:29.460
to provide us a third-party
support in our vegetation
00:59:29.460 --> 00:59:31.723
and risk assessments in that area.
00:59:33.330 --> 00:59:38.250
And then the other area
that is really bringing our GIS
00:59:38.250 --> 00:59:43.250
and data management up to
speed 'cause the data really
00:59:43.780 --> 00:59:46.930
and really drives our decisions
00:59:46.930 --> 00:59:51.930
and shows us the results of
where we're making difference,
00:59:52.170 --> 00:59:54.433
where we're maybe not making a difference,
00:59:55.710 --> 00:59:57.240
and where we ought to be heading.
00:59:57.240 --> 01:00:02.240
So it's really important we
allocate resources to that piece
01:00:02.460 --> 01:00:05.023
and that's where we're moving.
01:00:07.290 --> 01:00:12.290
So the big thing that we're
our next step is to transition
01:00:13.420 --> 01:00:16.920
to admission, calculating
admission probabilities
01:00:16.920 --> 01:00:21.920
at different points, and
also bringing on transitioning
01:00:22.350 --> 01:00:26.663
to a bow-tie style of risk assessment model.
01:00:27.662 --> 01:00:30.900
And our goal is to have that in operation
01:00:30.900 --> 01:00:35.900
sometime mid 2022, we'll be kicking off
01:00:36.150 --> 01:00:40.630
pretty soon a project to
take us to that next level
01:00:42.080 --> 01:00:46.478
in the risk assessment modeling
01:00:46.478 --> 01:00:51.478
and bring us on to that granularity
01:00:51.680 --> 01:00:55.963
of different ignition
points in our service area.
01:00:58.763 --> 01:01:02.073
And that's it for this session for me.
01:01:06.890 --> 01:01:10.090
Great, thank you for the presentation, Paul.
01:01:10.090 --> 01:01:14.620
And now, we're going to
enter into a short break.
01:01:14.620 --> 01:01:17.330
We are all going to come
back with the question
01:01:17.330 --> 01:01:20.430
and answer segments of today's workshop
01:01:20.430 --> 01:01:24.569
for our risk assessment
mapping and resource allocation.
01:01:24.569 --> 01:01:28.720
So we will all meet back here at 10:40
01:01:28.720 --> 01:01:31.390
and members of the
audiences this a great time
01:01:31.390 --> 01:01:34.240
to submit your questions via chat.
01:01:34.240 --> 01:01:36.190
So yeah, everyone, let's take a short break
01:01:36.190 --> 01:01:38.510
and we'll all be back at 10:40.
01:01:38.510 --> 01:01:39.343
Thank you.
01:09:05.560 --> 01:09:06.693
We're in session.
01:09:07.560 --> 01:09:12.560
So one thing I wanted
to note here is we're going
01:09:13.540 --> 01:09:18.540
to ask questions in order
of the different parties.
01:09:18.550 --> 01:09:23.550
So we have WSB here represented by me,
01:09:23.640 --> 01:09:28.240
and then we also have
the Green Power Institute.
01:09:28.240 --> 01:09:32.010
We also have the Public Advocate's Office
01:09:32.010 --> 01:09:33.830
and we also have Mr. Abrams,
01:09:33.830 --> 01:09:36.890
and then we'll also have Coco Tumasyan
01:09:36.890 --> 01:09:40.280
to read out the chat questions.
01:09:40.280 --> 01:09:42.260
So at this point here let's have
01:09:42.260 --> 01:09:46.070
all these stakeholder parties
use the raise hand feature
01:09:48.149 --> 01:09:53.149
in the in the WebEx, and we
won't leave the hand raised.
01:09:53.420 --> 01:09:56.090
And then what I'll do is
I'll start the cycles through
01:09:56.090 --> 01:09:57.960
and ask all the questions.
01:09:57.960 --> 01:10:02.960
And for all the panelists,
when asking questions,
01:10:03.120 --> 01:10:05.140
let's ask one question at a time.
01:10:05.140 --> 01:10:08.170
Totally fine if the question has multi parts,
01:10:08.170 --> 01:10:11.163
but we will go with water.
01:10:12.290 --> 01:10:17.290
And what we'll do here is
if a question is addressed
01:10:18.510 --> 01:10:22.320
to all three utilities, we'll
have the utilities answer
01:10:22.320 --> 01:10:26.400
in the order of PacifiCorp,
Liberty, and then Bear Valley
01:10:26.400 --> 01:10:30.620
just like how we went
through the presentations.
01:10:30.620 --> 01:10:35.527
So great, the first question
here is going to be from WSD.
01:10:36.740 --> 01:10:39.860
And this is the question for all utilities.
01:10:39.860 --> 01:10:42.170
Please describe at a high level
01:10:42.170 --> 01:10:45.550
the mitigation initiative selection process
01:10:45.550 --> 01:10:48.900
and pinpoint where the
outputs from the risk models.
01:10:48.900 --> 01:10:51.940
And this could be RSEs,
this could be identification
01:10:51.940 --> 01:10:55.060
of high risk segments and more are used
01:10:55.060 --> 01:10:57.713
in the decision-making process.
01:11:07.100 --> 01:11:09.710
So this is Heidi Caswell from PacifiCorp,
01:11:09.710 --> 01:11:12.880
and hopefully some of the graphics that were
01:11:12.880 --> 01:11:17.310
in presentation help
make it a little bit tied
01:11:18.595 --> 01:11:20.750
to the question well.
01:11:20.750 --> 01:11:25.750
So we use again that combined fire risk,
01:11:26.730 --> 01:11:30.720
which is the model output of the climate
01:11:33.330 --> 01:11:36.990
and fire climatology history
01:11:36.990 --> 01:11:41.000
to help identify areas that
01:11:42.226 --> 01:11:43.740
due to their location
01:11:43.740 --> 01:11:48.190
and environmental conditions, et cetera, are
01:11:51.880 --> 01:11:56.000
where a utility ignition could result
01:11:56.000 --> 01:11:59.580
in fire spread.
01:11:59.580 --> 01:12:01.290
So then on top of that,
01:12:01.290 --> 01:12:04.117
we lay that the utility ignition piece
01:12:04.117 --> 01:12:08.410
and the output is signaling
to us at that zonal level
01:12:10.470 --> 01:12:15.470
what the absolute value is
for that particular circuit zone.
01:12:17.980 --> 01:12:22.750
With that, we then look
to see what the drivers
01:12:22.750 --> 01:12:25.370
for that specific risk are.
01:12:25.370 --> 01:12:26.870
So is it something to do
01:12:26.870 --> 01:12:31.870
with how the arc energy manifests itself,
01:12:35.720 --> 01:12:37.980
what the vegetation history is,
01:12:37.980 --> 01:12:41.270
what the historic outages might be,
01:12:41.270 --> 01:12:43.650
and all of those help us then understand
01:12:44.936 --> 01:12:48.667
what particular symptom
that segment experiences
01:12:51.430 --> 01:12:55.810
then to the mapping that was identified
01:12:55.810 --> 01:13:00.380
where we outline what the cause history is
01:13:00.380 --> 01:13:04.490
that helps us get into an understanding of
01:13:05.430 --> 01:13:08.880
what kind of events
01:13:08.880 --> 01:13:12.973
that particular area would be susceptible to.
01:13:14.060 --> 01:13:17.660
And then we look to see
whether fault response,
01:13:17.660 --> 01:13:21.370
inspection and maintenance
programs, vegetation management,
01:13:21.370 --> 01:13:26.180
or asset hardening would
be the best way to mitigate
01:13:26.180 --> 01:13:30.810
for that particular risk event driver.
01:13:30.810 --> 01:13:34.720
And with that, then we start to look
01:13:34.720 --> 01:13:37.820
at how much any one of those measures
01:13:37.820 --> 01:13:40.810
potentially buys down our risk.
01:13:40.810 --> 01:13:45.130
One of the areas that we
have worked to do is quantifying
01:13:45.130 --> 01:13:49.953
that risk spend efficiency,
that is kind of the next target
01:13:51.500 --> 01:13:54.060
that we're striving for is
01:13:54.060 --> 01:13:58.990
some of the incorporating
the effectiveness measures
01:13:58.990 --> 01:14:03.990
to identify how much that risk is improved
01:14:05.160 --> 01:14:08.400
at a quantitative level
instead of the qualitative level
01:14:08.400 --> 01:14:10.343
that we've used in the past.
01:14:11.710 --> 01:14:15.050
But that's generally the
approach that we've been taking
01:14:15.050 --> 01:14:20.050
and then in terms of
its impact, the probability
01:14:20.730 --> 01:14:23.170
and the impact of the event,
01:14:23.170 --> 01:14:25.427
it helps identify them the prioritization
01:14:25.427 --> 01:14:28.963
for that particular zone
being advanced further.
01:14:32.510 --> 01:14:36.943
Great, thank you, Heidi,
and next up we have Liberty.
01:14:40.100 --> 01:14:43.590
All right, yes, so Liberty the approach
01:14:43.590 --> 01:14:46.630
that we use is looking at those RSEs
01:14:46.630 --> 01:14:50.430
and as part of those RSE calculations,
01:14:50.430 --> 01:14:54.009
there are a lot of factors that go into that.
01:14:54.009 --> 01:14:56.830
So during the presentation,
01:14:56.830 --> 01:15:01.830
I mentioned that we do look in many cases
01:15:02.190 --> 01:15:06.370
at the segments span
level of our particular circuits.
01:15:06.370 --> 01:15:10.300
And at that particular segment in span level,
01:15:10.300 --> 01:15:13.310
there were three different
risks that we looked at
01:15:13.310 --> 01:15:16.840
in addition to the factors that react scored
01:15:16.840 --> 01:15:20.860
for us at that particular segment or span.
01:15:20.860 --> 01:15:24.490
But those three risks were vegetation risk,
01:15:24.490 --> 01:15:29.000
our asset condition risk,
and our performance risk.
01:15:29.000 --> 01:15:33.790
And that was in the form of
what was the type of driver
01:15:33.790 --> 01:15:36.060
that caused a forced outage.
01:15:36.060 --> 01:15:40.610
So a lot of the factors we
saw in the WMP are like,
01:15:40.610 --> 01:15:42.770
if an animal chews our circuit
01:15:44.089 --> 01:15:48.350
or if a tree branch cuts our wire,
01:15:48.350 --> 01:15:51.830
anything that we can attach to a risk driver.
01:15:51.830 --> 01:15:53.970
What we try to do is look
01:15:53.970 --> 01:15:56.380
at our outage management system output,
01:15:56.380 --> 01:16:00.849
trace that to the location
and record those details.
01:16:00.849 --> 01:16:05.330
So next, when we looked
at particular mitigations
01:16:05.330 --> 01:16:08.350
that addressed certain risk drivers,
01:16:08.350 --> 01:16:13.350
we can look at the statistics
in terms of the number
01:16:13.900 --> 01:16:18.390
of forced outages by type and also the number
01:16:18.390 --> 01:16:20.063
of those force outages.
01:16:20.920 --> 01:16:24.380
And we can look at if
these mitigations reduce
01:16:24.380 --> 01:16:27.203
these risk drivers from occurring,
01:16:28.090 --> 01:16:32.810
and if they, then that that is what factors
01:16:32.810 --> 01:16:35.493
into our RSE calculations.
01:16:37.100 --> 01:16:40.730
So that is the main basis.
01:16:40.730 --> 01:16:45.730
We recently just completed our
modeling to reach those RSEs.
01:16:47.910 --> 01:16:50.957
And again, this is in the
same form as the MAVS
01:16:52.100 --> 01:16:53.510
in the MARS methodology
01:16:53.510 --> 01:16:58.510
that the larger IOUs
have completed previously.
01:16:58.520 --> 01:17:01.260
So we really haven't had much time
01:17:01.260 --> 01:17:06.260
to incorporate the RSE
values into our decision-making
01:17:06.310 --> 01:17:08.930
in terms of wildfire risk,
01:17:08.930 --> 01:17:13.930
but certainly what we've
already started to discuss
01:17:13.930 --> 01:17:17.023
in terms of how we will be factoring that in.
01:17:18.068 --> 01:17:21.040
And then of course, there are other factors
01:17:21.040 --> 01:17:23.460
that you look at in addition to RSE.
01:17:23.460 --> 01:17:27.530
So this also has to do with timing, costs,
01:17:27.530 --> 01:17:30.540
resource constraints, for example,
01:17:30.540 --> 01:17:35.540
a lot of times permitting
is an issue of doing a lot
01:17:36.172 --> 01:17:37.800
of work in the Tahoe area.
01:17:37.800 --> 01:17:41.500
So there are other
considerations that we do take
01:17:41.500 --> 01:17:44.980
into consideration when
selecting a particular mitigation,
01:17:44.980 --> 01:17:49.980
but now, that we do have the
tool to produce those RFEs,
01:17:50.090 --> 01:17:51.410
we're going to incorporate
01:17:51.410 --> 01:17:55.210
that into our forward-looking
capital investment
01:17:55.210 --> 01:17:57.410
in operating and maintenance decision-making
01:18:00.750 --> 01:18:02.952
Great, thank you for that answer, Greg.
01:18:02.952 --> 01:18:04.453
And lastly, Bear Valley.
01:18:05.540 --> 01:18:08.040
Yeah, I'll be brief here
01:18:08.040 --> 01:18:12.580
and what I'll do is walk
you through an example.
01:18:12.580 --> 01:18:15.140
We were looking at an evacuation hardening
01:18:15.140 --> 01:18:17.750
and there are a number of alternatives,
01:18:17.750 --> 01:18:19.513
obviously, you could underground,
01:18:20.700 --> 01:18:25.180
you could put a fire resistant composite,
01:18:25.180 --> 01:18:28.690
lightweight steel poles,
replace the wood poles,
01:18:28.690 --> 01:18:33.680
or you can also install what's
called a wire mesh wraps
01:18:33.680 --> 01:18:36.050
that wraps around the base of the pole
01:18:36.050 --> 01:18:37.500
and goes up a certain height.
01:18:38.450 --> 01:18:41.473
And those are all good alternatives.
01:18:42.350 --> 01:18:45.430
Probably, the least
satisfying is a wire mesh,
01:18:45.430 --> 01:18:48.350
but it does do the job, okay.
01:18:48.350 --> 01:18:53.350
At $950 a pole that's RSE goes up quite high.
01:18:55.360 --> 01:18:57.650
Whereas when compared to replacing the pole
01:18:57.650 --> 01:19:00.270
or even undergrounding,
01:19:00.270 --> 01:19:02.663
those are much more expensive options.
01:19:03.520 --> 01:19:08.520
And so get an immediate
grip on the problem and solve it.
01:19:08.890 --> 01:19:11.673
We have over 800 poles
on our evacuation routes,
01:19:14.810 --> 01:19:18.160
output drove us to, hey,
let's get the wrap on the poles
01:19:18.160 --> 01:19:19.910
in the next two years
01:19:19.910 --> 01:19:24.080
and then implement a policy
that whenever we replace a pole
01:19:24.080 --> 01:19:29.080
for whatever reason, we'll
replace it with lightweight steel
01:19:29.080 --> 01:19:32.243
or fire resistant composite pole.
01:19:32.243 --> 01:19:36.120
And so you can get that balance achieved
01:19:36.120 --> 01:19:39.970
for the risk reduction in a very efficient
01:19:39.970 --> 01:19:42.220
and cost effective manner.
01:19:42.220 --> 01:19:44.530
And then in the long
run, as you replace poles
01:19:44.530 --> 01:19:47.570
for other reasons or development and so forth
01:19:48.520 --> 01:19:53.520
you can use that RFC to
drive your policy in the future.
01:19:58.590 --> 01:20:01.030
Great, thank you for that, Paul.
01:20:01.030 --> 01:20:03.630
And then next let's go the panelist
01:20:03.630 --> 01:20:06.353
for Green Power Institute.
01:20:08.980 --> 01:20:09.900
Great, so Zoe Harrold
01:20:09.900 --> 01:20:12.210
with the Green Power Institute,
01:20:12.210 --> 01:20:13.790
thank you for all of these presentations.
01:20:13.790 --> 01:20:18.790
My question is related
to essentially dataset size,
01:20:19.430 --> 01:20:21.940
so compared to the IOUs,
01:20:21.940 --> 01:20:25.780
the SMG used have much
smaller risks event outage
01:20:25.780 --> 01:20:29.070
and ignition dataset,
and this can really make
01:20:30.670 --> 01:20:34.410
essentially the predictive
modeling approach very difficult.
01:20:34.410 --> 01:20:36.970
So I was hoping you
could each talk a bit about
01:20:36.970 --> 01:20:40.050
how you actually overcame
this modeling limitation.
01:20:40.050 --> 01:20:40.883
Thank you.
01:20:46.740 --> 01:20:49.262
So this is Heidi Caswell from PacifiCorp
01:20:49.262 --> 01:20:53.450
and great observation.
01:20:53.450 --> 01:20:56.680
We actually ran into this issue
01:20:56.680 --> 01:21:00.660
as a fairly substantial
one when you try to create
01:21:00.660 --> 01:21:05.660
some kind of risk event
to ignition relationship.
01:21:07.168 --> 01:21:11.280
And that is actually the
reason that we didn't try
01:21:11.280 --> 01:21:15.300
to do anything mathematically
in those two pie charts
01:21:15.300 --> 01:21:20.300
other than to draw the
correlations about the observation
01:21:20.760 --> 01:21:24.593
and not not try to turn it
into a number of essentially.
01:21:25.750 --> 01:21:28.500
The hope that we have over the next
01:21:28.500 --> 01:21:33.500
kind of model development
is to try to extend our reach
01:21:33.910 --> 01:21:38.843
in terms of application
of the ignition probability
01:21:40.740 --> 01:21:45.740
for specific fire risks or for risk events
01:21:45.800 --> 01:21:49.890
so that we become more
quantitative with that.
01:21:49.890 --> 01:21:53.390
And that might be by reaching out
01:21:53.390 --> 01:21:56.950
to the large IOUs to
determine whether there's
01:21:56.950 --> 01:22:00.200
any kind of extensible data that exists
01:22:00.200 --> 01:22:05.200
within their datasets that
we could kind of attempt
01:22:05.760 --> 01:22:10.760
to leverage or by continuing to just work
01:22:11.572 --> 01:22:16.572
with a smaller data set that
we have extended into other,
01:22:17.280 --> 01:22:19.080
we have other service territory apart.
01:22:19.080 --> 01:22:21.120
So perhaps there's some opportunity
01:22:21.120 --> 01:22:25.490
for outside of California informing
01:22:25.490 --> 01:22:27.563
some of the relationships.
01:22:33.610 --> 01:22:34.860
Hopefully that's helpful.
01:22:37.500 --> 01:22:39.220
Very helpful, thank you.
01:22:39.220 --> 01:22:41.903
And then Liberty and Bear Valley.
01:22:44.290 --> 01:22:46.430
Yeah, that was an excellent question.
01:22:46.430 --> 01:22:48.250
I'm glad you asked that.
01:22:48.250 --> 01:22:53.250
So that is absolutely
a challenge for Liberty,
01:22:53.770 --> 01:22:57.800
perhaps applying most of the Liberty
01:22:57.800 --> 01:23:02.640
because we are such a
new utility in this space.
01:23:02.640 --> 01:23:07.640
So one example, that
challenge that it did present to us
01:23:07.770 --> 01:23:09.120
in addition to the lack
01:23:10.025 --> 01:23:12.600
of real depth of history of our datasets
01:23:13.550 --> 01:23:17.890
that we did try to use a
neural network approach
01:23:17.890 --> 01:23:22.090
that the larger IOUs and I
believe also a Heidi mentioned
01:23:22.090 --> 01:23:26.210
that PacifiCorp was using,
the problem that we ran
01:23:26.210 --> 01:23:30.850
into is once we were utilizing that approach,
01:23:30.850 --> 01:23:34.170
we found that we really
didn't have enough history
01:23:34.170 --> 01:23:38.020
of data points to make
it that reliable compared
01:23:38.020 --> 01:23:40.160
to using a more standard approach,
01:23:40.160 --> 01:23:45.050
which would basically be
weighting each outage type
01:23:45.050 --> 01:23:48.190
equally in the prediction
of a wildfire risk event.
01:23:48.190 --> 01:23:51.530
So in a neural network,
there's a lot of feedback
01:23:51.530 --> 01:23:56.530
in terms of if this occurs
then in a lot of information is
01:23:56.540 --> 01:23:59.260
basically looped for each observation.
01:23:59.260 --> 01:24:03.070
But unfortunately, we weren't able to look
01:24:03.070 --> 01:24:06.780
at those results as reliable
as a standard approach.
01:24:06.780 --> 01:24:09.210
So we did go with a standard approach
01:24:09.210 --> 01:24:11.573
to come up with our RFEs.
01:24:12.660 --> 01:24:16.240
In terms of looking
outside of our own datasets,
01:24:16.240 --> 01:24:20.800
that's something that we
are definitely exploring.
01:24:20.800 --> 01:24:23.040
So we've talked with Bear Valley
01:24:23.040 --> 01:24:26.450
about doing that too last summer,
01:24:26.450 --> 01:24:29.770
how are ways that we
can help help each other?
01:24:29.770 --> 01:24:31.880
I think we're still in the discussion phase
01:24:31.880 --> 01:24:34.100
of just what that looks like,
01:24:34.100 --> 01:24:36.230
but it's definitely on our radar,
01:24:36.230 --> 01:24:39.263
and it's something that
Liberty it looks forward to doing.
01:24:47.150 --> 01:24:48.900
Yeah, it's a great question.
01:24:48.900 --> 01:24:51.320
It reminds me of my statistic professor,
01:24:51.320 --> 01:24:55.510
figures lie and liars figure statement.
01:24:55.510 --> 01:24:58.600
So you do have to look at
what you're doing in statistics,
01:24:58.600 --> 01:25:02.560
you can quantify the amount of error, right?
01:25:02.560 --> 01:25:04.460
Based on the amount of data you have.
01:25:04.460 --> 01:25:08.370
So when you do look at the
numbers, see you do look at them
01:25:08.370 --> 01:25:12.020
with eyes wide open and caution that.
01:25:12.020 --> 01:25:14.980
We have the benefit, however small
01:25:15.830 --> 01:25:20.310
of having a database that
goes back now about 20 years.
01:25:20.310 --> 01:25:23.120
So we look back further in the past
01:25:24.220 --> 01:25:29.090
to sorta glean and increase our database.
01:25:29.090 --> 01:25:33.040
The other thing I would
just say that, you know
01:25:33.040 --> 01:25:35.090
as much as a heavy list that is at least
01:25:35.090 --> 01:25:38.570
for small utilities to be
these quarterly data reports
01:25:38.570 --> 01:25:42.620
and so forth, they do give us
a glimpse at what all the data
01:25:42.620 --> 01:25:46.877
from other utilities and so those pay off
01:25:48.310 --> 01:25:51.610
and increasing our ability to assess
01:25:51.610 --> 01:25:53.590
and look at a broader picture.
01:25:53.590 --> 01:25:54.423
And then once again,
01:25:54.423 --> 01:25:58.230
collaborating between the
utilities would be beneficial
01:25:58.230 --> 01:25:59.673
in resolving that issue.
01:26:05.230 --> 01:26:06.693
Great, thanks, everyone.
01:26:09.820 --> 01:26:11.960
All right, thank you for that question, Zoe.
01:26:11.960 --> 01:26:14.693
Next, let's move on to the
Public Advocate's Office.
01:26:18.070 --> 01:26:20.823
Okay, this is Henry Burton,
can you hear me okay?
01:26:25.110 --> 01:26:26.410
Yep.
01:26:26.410 --> 01:26:30.020
Okay, great, so I'll start with PacifiCorp.
01:26:30.020 --> 01:26:32.013
A question for PacifiCorp,
01:26:33.580 --> 01:26:37.460
you mentioned using a Cal-Adapt tool to
01:26:39.550 --> 01:26:43.970
estimate or model climate
change trends over time,
01:26:43.970 --> 01:26:45.200
can you elaborate a bit on that
01:26:45.200 --> 01:26:47.523
and how you used it for your risk analysis?
01:26:49.120 --> 01:26:54.120
Yeah, so in the model,
there was the expression
01:26:55.510 --> 01:26:58.360
or the the demonstration, I
think of the different layers
01:26:59.200 --> 01:27:00.310
that are incorporated
01:27:03.070 --> 01:27:08.000
as additional inputs for
the calculation process.
01:27:08.000 --> 01:27:13.000
And with the Cal-Adapt data
what we did was looked at,
01:27:13.710 --> 01:27:16.000
I think, four different scenarios
01:27:16.000 --> 01:27:20.890
for the climate change
out to 2030 at this point.
01:27:20.890 --> 01:27:25.360
And basically, we're
looking to see the variation
01:27:25.360 --> 01:27:30.360
that occurs for the contemporary
climate aspect of the model
01:27:32.870 --> 01:27:37.870
with regard to the fire weather
indices and the dryness.
01:27:38.520 --> 01:27:42.920
So it was specifically focused
on what would we expect
01:27:44.840 --> 01:27:47.840
at the zonal level that
we've been talking about
01:27:47.840 --> 01:27:52.840
with the change in local dryness
01:27:53.950 --> 01:27:57.070
during the extreme periods of the year,
01:27:57.070 --> 01:27:59.930
and then at the same time,
01:27:59.930 --> 01:28:03.760
how are the models suggesting
01:28:03.760 --> 01:28:06.220
that fire weather indices would change?
01:28:06.220 --> 01:28:09.130
And so those are around temperature extremes
01:28:09.130 --> 01:28:14.080
and wind extremes as
well, so gas specifically.
01:28:14.080 --> 01:28:19.040
And with that, we then were
able to identify the zones
01:28:19.040 --> 01:28:23.800
that had the most substantial impact
01:28:26.030 --> 01:28:30.920
as far as the ramping up their combined fires
01:28:30.920 --> 01:28:32.183
or combined scores.
01:28:33.040 --> 01:28:38.040
So that was the output, there's actually,
01:28:38.330 --> 01:28:41.672
it's a little tough to tell the specific
01:28:41.672 --> 01:28:45.520
because it's really best
viewed in the model way,
01:28:45.520 --> 01:28:47.750
but there's a graphic that demonstrates
01:28:48.992 --> 01:28:53.992
that distribution of climate
variation as a function of time
01:28:54.730 --> 01:28:59.730
at the zonal level in
our fire risk assessments
01:28:59.920 --> 01:29:04.083
or in the risk modeling in 4.5.1 in our WMP.
01:29:07.400 --> 01:29:09.040
And we anticipate refreshing
01:29:09.040 --> 01:29:14.040
that as Cal-Adapters future
climate change models
01:29:16.590 --> 01:29:20.120
are produced and we have
begun some conversation,
01:29:20.120 --> 01:29:25.120
I think it's mentioned in the
document as well with the
01:29:25.540 --> 01:29:30.540
climate work stream that's
part of the Pyrogens project.
01:29:35.470 --> 01:29:37.520
Great, and for the other two utilities,
01:29:38.537 --> 01:29:40.750
did you use Cal-Adapt or a similar tool
01:29:40.750 --> 01:29:41.800
for the same purpose?
01:29:51.500 --> 01:29:54.140
Henry, could you repeat
that question one more time?
01:29:54.140 --> 01:29:56.340
I think I just want to make sure
01:29:56.340 --> 01:29:58.850
I can answer it fully, yeah
01:29:58.850 --> 01:30:03.850
Sure, so the question was,
did you use the Cal-Adapt tool
01:30:04.530 --> 01:30:09.250
to understand climate
trends over the coming decade
01:30:09.250 --> 01:30:13.520
or two and or do you use a similar tool
01:30:13.520 --> 01:30:17.110
and could you describe
a little bit how you looked
01:30:17.110 --> 01:30:18.010
at kind of trends?
01:30:20.080 --> 01:30:22.180
Sure, that's a good question, thanks Henry.
01:30:22.180 --> 01:30:25.690
So as part of looking at our climate trends
01:30:25.690 --> 01:30:30.310
and anything that would
be related to climate change
01:30:30.310 --> 01:30:33.200
and how it does affect our wildfire risks,
01:30:33.200 --> 01:30:38.200
that would be part of the
Reax analysis that we use.
01:30:38.540 --> 01:30:41.120
So whatever trends that they identified
01:30:41.120 --> 01:30:45.850
or whatever input variables
are related to climate change
01:30:45.850 --> 01:30:49.220
that was part of their
fire propagation models
01:30:49.220 --> 01:30:52.070
that we incorporated into our analysis
01:30:52.070 --> 01:30:53.870
that's where that would be captured.
01:30:58.580 --> 01:30:59.980
Yeah, for Bear Valley,
01:30:59.980 --> 01:31:01.570
I don't think we use the Cal-Adapt,
01:31:01.570 --> 01:31:04.470
but we did look at climate change studies.
01:31:04.470 --> 01:31:08.610
Our area is very small,
so it's almost a pixel
01:31:08.610 --> 01:31:13.610
in the picture, but what
we did look at, for example,
01:31:15.150 --> 01:31:19.620
right now, due to the
winds during dry periods are
01:31:19.620 --> 01:31:23.440
typically pretty historically
are not high for us to a point
01:31:23.440 --> 01:31:26.313
where we would act initiate PSPS.
01:31:27.830 --> 01:31:32.070
But we did look at, hey, if we did nothing
01:31:32.070 --> 01:31:35.060
to harden some of our systems,
01:31:35.060 --> 01:31:38.390
and you look at the climate change occurring,
01:31:38.390 --> 01:31:42.700
we would in the future be in PSPS scenarios,
01:31:42.700 --> 01:31:46.450
and therefore taking a
lead angle on this problem,
01:31:46.450 --> 01:31:51.450
we did use that kind of
information as we planned mitigation
01:31:52.077 --> 01:31:54.773
and so forth looking towards the future.
01:31:59.940 --> 01:32:00.840
Okay, thank you.
01:32:04.890 --> 01:32:07.590
All right, thank you,
Henry, for the question.
01:32:07.590 --> 01:32:10.070
Next, we're gonna move on to Mr. Abrams.
01:32:26.080 --> 01:32:27.410
And Mr. Abrams,
01:32:27.410 --> 01:32:29.293
can you be sure to unmute your phone?
01:32:53.260 --> 01:32:55.140
Let's give it a few more seconds here.
01:32:55.140 --> 01:32:59.130
If not, we can move on to the
chat questions if we have any
01:32:59.130 --> 01:33:01.230
and then we can circle back to Mr. Abrams.
01:33:02.770 --> 01:33:05.060
Hey, Alan, this is Coco while we're waiting
01:33:05.060 --> 01:33:08.910
for Mr. Abrams audio
just wanted to let you know
01:33:08.910 --> 01:33:11.820
we have not received any questions yet
01:33:11.820 --> 01:33:15.163
in the chat so you can circle back.
01:33:16.880 --> 01:33:19.233
Great, thank you so much, Coco.
01:33:23.380 --> 01:33:26.090
Well, let's go into the next question for WSD
01:33:26.090 --> 01:33:29.630
and Mr. Abrams when you're
able to get the audio working,
01:33:29.630 --> 01:33:31.890
go ahead and let us know
01:33:31.890 --> 01:33:34.857
and we'll put you up next for questions.
01:33:35.730 --> 01:33:39.950
So this next question here is
targeted towards PacifiCorp,
01:33:39.950 --> 01:33:42.670
but I would also like to hear Liberty
01:33:42.670 --> 01:33:45.650
and Bear Valley's approaches as well.
01:33:45.650 --> 01:33:49.630
So PacifiCorp, in the 2021 WMP update,
01:33:49.630 --> 01:33:53.910
we have figure 4.2-3, which is the breakdown
01:33:53.910 --> 01:33:58.910
of annual distribution of risk
events by cause categories.
01:33:59.130 --> 01:34:03.620
And from 2015 to 2020 even though the amount
01:34:03.620 --> 01:34:05.760
of risk events fluctuates,
01:34:05.760 --> 01:34:10.570
the category of unknown
is staying proportional
01:34:10.570 --> 01:34:15.070
and it's one of the higher brackets.
01:34:15.070 --> 01:34:17.520
So I'm wondering what is the utility doing
01:34:17.520 --> 01:34:20.193
to better understand the unknown category?
01:34:24.470 --> 01:34:26.440
That is a super question,
01:34:26.440 --> 01:34:31.440
so for us unknown is the natural response
01:34:31.820 --> 01:34:35.450
to that unknown would be
to give guidance to people
01:34:35.450 --> 01:34:38.690
to help them decide how to code it.
01:34:38.690 --> 01:34:41.640
But we did not want to
corrupt the data that we have.
01:34:41.640 --> 01:34:46.280
So it's important for us
to make sure that we build
01:34:48.942 --> 01:34:51.810
the investigative competency
01:34:51.810 --> 01:34:55.970
so that we actually are
able to turn an unknown
01:34:56.919 --> 01:34:58.100
into certain known.
01:34:58.100 --> 01:34:58.933
So
01:35:01.230 --> 01:35:03.540
oftentimes, what ends up happening is
01:35:03.540 --> 01:35:07.490
whatever the evidence would
have been about what's a fault
01:35:08.730 --> 01:35:11.200
or the risk event was his bound
01:35:11.200 --> 01:35:13.630
by the time patrolmen gets there
01:35:13.630 --> 01:35:17.060
or it was a transient sort of event.
01:35:17.060 --> 01:35:21.253
And didn't actually leave any indications.
01:35:22.170 --> 01:35:24.900
With the eye, you
wouldn't necessarily be able
01:35:24.900 --> 01:35:26.800
to detect what that was.
01:35:26.800 --> 01:35:29.760
As we are moving forward with the deployment
01:35:29.760 --> 01:35:34.760
of many of the relay replacements
that are part of our plan
01:35:35.550 --> 01:35:39.170
as well as then recloser control
01:35:42.170 --> 01:35:44.270
technology, we'll be in a better position
01:35:44.270 --> 01:35:47.340
to actually diagnose the specific locations
01:35:47.340 --> 01:35:51.520
and have better targeted inspection
01:35:51.520 --> 01:35:53.060
of those particular areas
01:35:53.060 --> 01:35:56.827
so that those unknowns can be made known
01:35:58.940 --> 01:36:02.780
but not necessarily by
the immediate responders.
01:36:02.780 --> 01:36:06.020
But it'll be on the follow-up action
01:36:06.020 --> 01:36:10.120
as opposed to on the outage
restoration that we're able
01:36:10.120 --> 01:36:12.230
to determine what the known is.
01:36:12.230 --> 01:36:13.940
And we do that actually
01:36:15.460 --> 01:36:19.461
through some post-processing that happens
01:36:19.461 --> 01:36:22.880
or we will be doing that
some through post processing
01:36:22.880 --> 01:36:24.530
that happens with
01:36:27.660 --> 01:36:31.420
mining, that outage history
and triggering notifications
01:36:31.420 --> 01:36:34.053
to people that conduct those analysis.
01:36:39.580 --> 01:36:42.963
Got it, thank you, Heidi,
Liberty and Bear Valley.
01:36:45.650 --> 01:36:47.450
Yes, that's a great question.
01:36:47.450 --> 01:36:51.863
So as I referenced
earlier in the presentation,
01:36:52.730 --> 01:36:56.660
we have upgraded our
outage management system.
01:36:56.660 --> 01:37:00.700
And as part of that upgrade,
it will do a couple of things.
01:37:00.700 --> 01:37:05.638
The first thing is that it
does produce a report
01:37:05.638 --> 01:37:10.310
that contains a lot more
details in terms and data points
01:37:10.310 --> 01:37:12.290
in terms of what the
Commission was looking for.
01:37:12.290 --> 01:37:14.477
And some of those data points were
01:37:14.477 --> 01:37:17.720
if it was energized equipment,
01:37:17.720 --> 01:37:21.820
how many splices that were there?
01:37:21.820 --> 01:37:26.820
What type of equipment
was the fault on, the location?
01:37:28.030 --> 01:37:30.450
So some of those data points are now features
01:37:30.450 --> 01:37:34.170
as part of this new report that we have.
01:37:34.170 --> 01:37:37.053
A couple other things
that the company is doing.
01:37:38.020 --> 01:37:41.610
And that's part of creating this new report,
01:37:41.610 --> 01:37:43.900
there were more options
01:37:43.900 --> 01:37:46.940
or the communication between our dispatch
01:37:46.940 --> 01:37:51.360
and our trouble men to log in
our outage management system.
01:37:51.360 --> 01:37:54.200
So what we did was we retrained
01:37:54.200 --> 01:37:58.770
and went over of these new
options with our dispatch teams
01:37:59.640 --> 01:38:01.830
as well is our field workers
01:38:01.830 --> 01:38:05.697
in order to properly
capture those data points
01:38:05.697 --> 01:38:09.440
and have those data points
be accurate in the report
01:38:09.440 --> 01:38:14.440
because that will eventually
feed into our risk models.
01:38:14.980 --> 01:38:19.540
So I think that that's going
to have some improvement
01:38:19.540 --> 01:38:24.480
over a lot of these data points
that got listed as unknown.
01:38:24.480 --> 01:38:29.400
So we'll have to see going
forward what that looks like,
01:38:29.400 --> 01:38:30.930
what is our expectation
01:38:30.930 --> 01:38:34.160
that the unknown category will decrease
01:38:34.160 --> 01:38:35.740
with these new options
01:38:35.740 --> 01:38:40.463
and with us producing this
report and retraining our staff.
01:38:43.660 --> 01:38:45.127
Great, thank you, Greg.
01:38:49.463 --> 01:38:53.360
I don't think our unknown
is that large a number,
01:38:53.360 --> 01:38:57.300
but we do have, and we've been doing
01:38:57.300 --> 01:38:59.130
this now for about four years,
01:38:59.130 --> 01:39:04.047
a very detailed prescriptive
report that the patrolman use.
01:39:05.210 --> 01:39:06.620
So they don't have a lot of options,
01:39:06.620 --> 01:39:09.080
they have to check the most appropriate.
01:39:09.080 --> 01:39:11.520
And then the next day there's follow up
01:39:11.520 --> 01:39:12.810
and if we have questions,
01:39:12.810 --> 01:39:15.303
we sit down with the patrolman, get pictures.
01:39:16.200 --> 01:39:21.080
So being on top of the
data gathering is important
01:39:21.080 --> 01:39:22.860
and making sure it's done real time
01:39:22.860 --> 01:39:24.940
rather than at the end of the quarter,
01:39:24.940 --> 01:39:27.453
you're trying to do your quarterly upload.
01:39:28.797 --> 01:39:30.450
And now, you're trying to reach back a couple
01:39:30.450 --> 01:39:33.300
of months and figure out
what happened that night.
01:39:33.300 --> 01:39:36.740
So that's important.
01:39:36.740 --> 01:39:39.523
There are genuinely events that are unknown,
01:39:42.440 --> 01:39:47.440
I mean, sometimes, an OCD will will open,
01:39:47.890 --> 01:39:50.600
you'll patrol it, you'll patrol it again.
01:39:50.600 --> 01:39:52.370
Okay, we test it, it's fine.
01:39:52.370 --> 01:39:56.339
We patrol it again just to
see if we missed something
01:39:56.339 --> 01:39:59.100
and you don't, you it's not there.
01:39:59.100 --> 01:40:00.950
So there are a few that are gonna be
01:40:00.950 --> 01:40:05.950
in that unknown category
and just the fact of life.
01:40:08.730 --> 01:40:11.340
Can I add to my answer, please?
01:40:11.340 --> 01:40:15.190
It kind of precipitated by
what Paul just mentioned,
01:40:15.190 --> 01:40:17.140
which is historically
01:40:17.140 --> 01:40:21.823
and I think Zoe's question
really tip this one off is
01:40:21.823 --> 01:40:26.823
that we have long history of outage records
01:40:26.840 --> 01:40:29.880
and those systems may have changed over time.
01:40:29.880 --> 01:40:34.880
The goal of the outage was
to solve and restore power.
01:40:34.890 --> 01:40:37.400
Now, what we're doing
is we're using that outage
01:40:38.277 --> 01:40:40.300
as a proxy for risk events.
01:40:40.300 --> 01:40:42.750
And so we're in the past and unknown
01:40:42.750 --> 01:40:45.300
as long as you had the power restored was
01:40:45.300 --> 01:40:48.470
kind of I looked for everything,
everything looked fine.
01:40:48.470 --> 01:40:51.230
I couldn't actually detect what it was.
01:40:51.230 --> 01:40:56.230
It was an acceptable
outcome to leave it at that point.
01:40:56.290 --> 01:40:57.990
Now, it's less acceptable,
01:40:57.990 --> 01:41:00.220
and so we have to build different processes
01:41:00.220 --> 01:41:03.560
in order to actually go
deeper into that investigation
01:41:03.560 --> 01:41:07.309
and that's what we're
really trying to recognize
01:41:07.309 --> 01:41:09.980
in our tool sets and move forward with
01:41:09.980 --> 01:41:11.993
so that we have better answers
01:41:11.993 --> 01:41:16.280
for those that can be made
known if we have more data
01:41:17.248 --> 01:41:20.260
to inform what probably happened
01:41:20.260 --> 01:41:24.410
or what maybe conclusively
happened when you have
01:41:24.410 --> 01:41:25.923
some of that electronic data.
01:41:29.840 --> 01:41:31.790
Great, thank you for all the answers.
01:41:33.220 --> 01:41:35.050
At this point here, I'm just sure.
01:41:35.050 --> 01:41:38.563
Abrams, are you able to
patch through with audio?
01:41:39.560 --> 01:41:42.100
I believe so, can you hear me?
01:41:42.100 --> 01:41:44.330
Yes, loud and clear, thank you.
01:41:44.330 --> 01:41:45.240
Great, thanks.
01:41:45.240 --> 01:41:47.183
I'm glad I was able to fix that.
01:41:48.520 --> 01:41:50.800
So I appreciated the presentation
01:41:50.800 --> 01:41:52.960
and really just had some questions
01:41:52.960 --> 01:41:55.160
around sort of the transparency
01:41:55.160 --> 01:41:59.537
of the information and the
degree to which collaboration
01:42:00.670 --> 01:42:05.640
particularly with local agencies contributes
01:42:05.640 --> 01:42:08.120
to how this information is used.
01:42:08.120 --> 01:42:12.513
So PacifiCorp talked
about, you talked about
01:42:12.513 --> 01:42:15.480
how there's this circuit prioritization map.
01:42:15.480 --> 01:42:17.750
And so just wanted to understand
01:42:17.750 --> 01:42:21.020
how much of that information is transparent.
01:42:21.020 --> 01:42:23.850
And so if I lived as an example in an area
01:42:23.850 --> 01:42:26.190
where there was one of those red dots,
01:42:26.190 --> 01:42:28.870
might that I'd be able to sort of contribute
01:42:28.870 --> 01:42:33.340
towards solutions to
sort of reducing the risk
01:42:33.340 --> 01:42:34.830
around that circuit.
01:42:34.830 --> 01:42:36.220
And how does that type
01:42:36.220 --> 01:42:38.940
of collaboration go back and forth?
01:42:38.940 --> 01:42:42.760
And similarly, sort of around
the sectionalization devices
01:42:42.760 --> 01:42:45.450
that are within your grid,
01:42:45.450 --> 01:42:48.880
how much of that information
is shared specifically
01:42:48.880 --> 01:42:52.670
about what types of
sectionalization devices are
01:42:52.670 --> 01:42:53.880
in what areas?
01:42:53.880 --> 01:42:58.880
And so does that also then
empower emergency managers
01:43:00.180 --> 01:43:04.090
or other folks to be able to help
01:43:04.090 --> 01:43:06.270
when there might be de-energization
01:43:06.270 --> 01:43:07.730
or there might be decisions
01:43:07.730 --> 01:43:11.070
around how to mitigate
that they're able to contribute
01:43:11.070 --> 01:43:14.920
in a way because they have this information?
01:43:14.920 --> 01:43:15.753
Thank you.
01:43:19.870 --> 01:43:22.730
So good questions there, Mr. Abrams.
01:43:22.730 --> 01:43:24.870
First off to this point,
01:43:24.870 --> 01:43:29.870
we haven't made the
zonal quantification of risk.
01:43:31.670 --> 01:43:34.370
Part of our conversation, we started
01:43:37.650 --> 01:43:41.810
with the sharing of our mitigation plans
01:43:41.810 --> 01:43:45.370
with the PSPS impact
01:43:45.370 --> 01:43:49.030
that we're really reliant
on the HFTD designation
01:43:50.147 --> 01:43:52.500
and attempted to be very transparent
01:43:52.500 --> 01:43:57.500
with customers and public
safety partners in that regard.
01:43:58.140 --> 01:44:01.770
In terms of that sexualization
question that you're asking,
01:44:01.770 --> 01:44:03.630
we went the other direction.
01:44:03.630 --> 01:44:08.630
And it's interesting to
hear your approach to it,
01:44:09.760 --> 01:44:14.610
with us, what we did was
we used the identification
01:44:14.610 --> 01:44:16.640
of where critical customers
01:44:16.640 --> 01:44:19.540
or medically vulnerable customers were
01:44:20.440 --> 01:44:23.020
at that section level, had the conversations
01:44:23.020 --> 01:44:26.250
with our emergency or with
the public safety partners,
01:44:26.250 --> 01:44:30.407
and then went backwards to
try to determine both mitigation
01:44:30.407 --> 01:44:32.950
and sectionalization opportunities.
01:44:32.950 --> 01:44:36.233
We've never identified, I guess,
01:44:37.560 --> 01:44:41.510
at a facility point level to
our public safety partners
01:44:41.510 --> 01:44:44.620
where each of those kinds of control points
01:44:45.620 --> 01:44:48.820
and maybe that's worthy
of a conversation with them.
01:44:48.820 --> 01:44:53.820
What we tried to do was to
use that whole PSPS impact
01:44:53.870 --> 01:44:57.796
and risk impact as a conversation.
01:44:57.796 --> 01:45:00.470
I don't know that we have yet figured out
01:45:00.470 --> 01:45:02.140
how to make the model usable
01:45:02.140 --> 01:45:07.140
if you don't have some
of the GIS data behind it,
01:45:07.830 --> 01:45:10.520
but certainly, it will have
some of those conversations
01:45:10.520 --> 01:45:13.090
with public safety partners,
01:45:13.090 --> 01:45:16.103
hopefully through our
Wildfire Safety Advisors Board.
01:45:25.080 --> 01:45:27.880
I think community
engagement is really important
01:45:29.110 --> 01:45:33.170
and we're a small enough
area, but there's always
01:45:34.740 --> 01:45:37.210
why is that street getting covered wire
01:45:37.210 --> 01:45:39.560
or when am I getting
covered wire on my street,
01:45:41.490 --> 01:45:44.550
small town issue.
01:45:44.550 --> 01:45:47.610
And so what we did was
we briefed the city manager
01:45:49.310 --> 01:45:52.480
for Big Bear Lake in a very detailed on
01:45:54.320 --> 01:45:56.880
how we arrived at the mitigation we selected
01:45:58.552 --> 01:46:01.470
and then how we were prioritizing them.
01:46:01.470 --> 01:46:04.770
And a good number of
them fall outside the area
01:46:04.770 --> 01:46:07.354
in the unincorporated areas.
01:46:07.354 --> 01:46:10.200
he really cares about the incorporated areas,
01:46:10.200 --> 01:46:12.880
but he understands why we're doing
01:46:12.880 --> 01:46:16.453
those areas first and how it's all linked.
01:46:17.420 --> 01:46:19.830
The other area that I use,
01:46:19.830 --> 01:46:21.570
I'm not sure if you're familiar
01:46:21.570 --> 01:46:25.390
with fire safe councils
throughout California,
01:46:25.390 --> 01:46:28.380
but I briefed those personally,
01:46:28.380 --> 01:46:32.870
take our plan slides and
briefed the fire safe councils
01:46:32.870 --> 01:46:34.740
'cause those are individuals,
01:46:34.740 --> 01:46:37.440
and if you're willing to
join a fire safe council,
01:46:37.440 --> 01:46:39.940
you're definitely a concerned person
01:46:39.940 --> 01:46:43.090
in your community about
fire safety and wildfires.
01:46:43.090 --> 01:46:45.790
And so those are people
that I like to reach out to
01:46:45.790 --> 01:46:48.690
because they spread the word
around the community as well.
01:46:54.700 --> 01:46:57.190
And for Liberty, we were still
01:46:58.120 --> 01:47:00.690
in the planning phase on that,
01:47:00.690 --> 01:47:03.950
but we do have emergency plan as well
01:47:03.950 --> 01:47:08.190
as a PSPS of protocols that we follow.
01:47:08.190 --> 01:47:11.603
So that's about the stage
where we're at right now.
01:47:16.333 --> 01:47:19.610
Thanks very much, I appreciate the answers.
01:47:19.610 --> 01:47:20.443
Really,
01:47:22.820 --> 01:47:26.590
my question, which I think was addressed is
01:47:28.200 --> 01:47:33.200
really to sort of have more collaboration
01:47:33.830 --> 01:47:38.830
around decision-making in
terms of the mitigation measures
01:47:39.430 --> 01:47:44.430
that are put forward so that
public officials are empowered
01:47:45.333 --> 01:47:47.470
to be able to say, "Well
01:47:47.470 --> 01:47:50.840
if you move this sectionalization device here
01:47:50.840 --> 01:47:54.230
and we're able to gate in this way,
01:47:54.230 --> 01:47:59.230
we can protect this
telecommunications infrastructure
01:47:59.320 --> 01:48:02.137
or limit the effects in this way,"
01:48:03.410 --> 01:48:07.820
or, "I know the landowners that are around
01:48:07.820 --> 01:48:12.110
this circuit where you've
identified that there's a risk,
01:48:12.110 --> 01:48:14.780
I can work with you to address it."
01:48:14.780 --> 01:48:17.580
So I guess just I really
appreciate the answers,
01:48:17.580 --> 01:48:19.590
I guess I just would say that it sounds
01:48:19.590 --> 01:48:22.170
like that's an area for further development,
01:48:22.170 --> 01:48:27.170
so that these partners in
the public can really be active
01:48:27.870 --> 01:48:32.180
in terms of working with you
in mitigation is going forward.
01:48:32.180 --> 01:48:33.503
But thank you very much.
01:48:38.280 --> 01:48:40.590
Thank you for that question, Mr. Abrams.
01:48:40.590 --> 01:48:42.820
And we about five minutes left here.
01:48:42.820 --> 01:48:46.100
So Henry, go ahead and take it away,
01:48:46.100 --> 01:48:47.680
and this will likely be the last question
01:48:47.680 --> 01:48:49.580
that we'll have with this Q&A session.
01:48:51.110 --> 01:48:52.936
Great,, okay, thank you.
01:48:52.936 --> 01:48:55.623
So I have a question
mainly intended for Liberty,
01:48:56.572 --> 01:49:00.760
Liberty if yours is relying on react
01:49:00.760 --> 01:49:03.460
for risk assessment and modeling,
01:49:03.460 --> 01:49:05.690
and so I have a couple of questions on that.
01:49:05.690 --> 01:49:10.460
One is how did you develop the polygon
01:49:10.460 --> 01:49:12.590
that you used to do risk analysis
01:49:12.590 --> 01:49:14.983
of different parts of your service territory?
01:49:16.360 --> 01:49:20.720
I'm just trying to understand
how you drew the polygons
01:49:20.720 --> 01:49:23.143
to identify discrete regions.
01:49:23.990 --> 01:49:26.120
And then secondly,
01:49:26.120 --> 01:49:31.120
how did you validate the
results that Reax provided
01:49:32.390 --> 01:49:34.390
in terms of risk modeling?
01:49:34.390 --> 01:49:35.223
How did
01:49:38.260 --> 01:49:41.290
route it or test it in the field to make sure
01:49:41.290 --> 01:49:46.290
that that risk modeling was
providing a reliable output?
01:49:52.340 --> 01:49:53.728
Yeah, thank you for that.
01:49:53.728 --> 01:49:54.830
Thank you for that question, Henry.
01:49:54.830 --> 01:49:59.830
So as part of how they
segmented off those areas,
01:50:02.735 --> 01:50:05.530
if you remember those green lines,
01:50:05.530 --> 01:50:08.260
some of those areas would follow
01:50:08.260 --> 01:50:11.630
where those circuits are located.
01:50:11.630 --> 01:50:14.310
So that was part of it.
01:50:14.310 --> 01:50:18.540
Another part of it is an elevation change,
01:50:18.540 --> 01:50:23.230
what type of vegetation of
ground fuels that were out there.
01:50:23.230 --> 01:50:25.310
So these are a lot of factors that go
01:50:25.310 --> 01:50:29.030
into their fire propagation models
01:50:29.030 --> 01:50:31.611
and what they were able to do
01:50:31.611 --> 01:50:33.750
as part of that modeling look at areas
01:50:33.750 --> 01:50:37.817
where if a significant wildfire themes.
01:50:41.410 --> 01:50:45.133
So for example, if we start
moving closer to Lake Tahoe,
01:50:46.240 --> 01:50:48.020
the fire spread would end
01:50:48.020 --> 01:50:52.680
because there's no
vegetation, there's no wood.
01:50:52.680 --> 01:50:57.201
There's nothing that's
going to have the fire,
01:50:57.201 --> 01:51:01.240
let's say if there was a
forest there in would carry,
01:51:01.240 --> 01:51:03.253
so that's one example.
01:51:04.140 --> 01:51:07.000
Another example too is that if we looked
01:51:07.000 --> 01:51:12.000
in areas that were heavily
commercialized, a lot of times
01:51:12.190 --> 01:51:16.030
these buildings aren't
necessarily great conductors
01:51:17.199 --> 01:51:19.740
of a wildfire, so the spread isn't going
01:51:19.740 --> 01:51:22.760
to escape containment
01:51:24.687 --> 01:51:25.550
as it was as easy as it would,
01:51:25.550 --> 01:51:28.930
say in a very heavily forest area,
01:51:28.930 --> 01:51:32.900
particularly with vegetation
or ground fuels that can
01:51:32.900 --> 01:51:36.260
really be conducive to wildfire spread.
01:51:36.260 --> 01:51:39.040
So there's a lot of things that are taken
01:51:39.040 --> 01:51:44.010
into consideration how to
area those often segmented off,
01:51:44.010 --> 01:51:46.930
but those were some of the different risks
01:51:46.930 --> 01:51:48.720
that they looked at and that we talked
01:51:48.720 --> 01:51:53.570
about how to change from
one category to the next
01:51:53.570 --> 01:51:56.777
and where one border would
start and the other would end.
01:51:57.700 --> 01:52:01.470
In terms of valid,
validating out in the field
01:52:01.470 --> 01:52:04.710
or what their outputs were.
01:52:04.710 --> 01:52:09.180
I think we're still in the collection,
01:52:09.180 --> 01:52:12.530
we're still sort of in the
beginning stages of that.
01:52:12.530 --> 01:52:17.350
I'm not sure we really
have a long enough history
01:52:17.350 --> 01:52:19.710
in terms of really validating.
01:52:19.710 --> 01:52:22.420
I think anytime you do something like that,
01:52:22.420 --> 01:52:26.000
you need to have a reliable
sample size to look backwards on
01:52:26.000 --> 01:52:29.886
and say, "Okay, yeah,
this is where we think it is."
01:52:29.886 --> 01:52:34.230
Maybe this needs to change,
so I think as time goes on,
01:52:34.230 --> 01:52:37.210
we're gonna be able to do that validation
01:52:37.210 --> 01:52:39.173
like you just mentioned.
01:52:40.930 --> 01:52:45.930
The analysis that they
completed for us wrapped up in Q3.
01:52:47.410 --> 01:52:49.996
So really we haven't really had
01:52:49.996 --> 01:52:54.330
that much time to really let what the scoring
01:52:54.330 --> 01:52:56.220
and rating that they've identified,
01:52:56.220 --> 01:52:59.770
then looking backwards
to any types of changes
01:52:59.770 --> 01:53:04.460
whether we need to say
something's more risky or less risky,
01:53:04.460 --> 01:53:07.847
but this is something
that we do have our eye on
01:53:07.847 --> 01:53:10.950
and this is something that
we know is gonna happen.
01:53:10.950 --> 01:53:14.168
We know that our first-generation models
01:53:14.168 --> 01:53:16.100
in the information that feeds
01:53:16.100 --> 01:53:18.950
into these first-generation
models will change,
01:53:18.950 --> 01:53:22.970
and we know not everything will be static.
01:53:22.970 --> 01:53:25.500
And so we do plan to keep an eye
01:53:25.500 --> 01:53:30.110
on that in the jobs as
we see of the data come
01:53:30.110 --> 01:53:32.643
and test it like you mentioned.
01:53:38.421 --> 01:53:39.421
Thank you.
01:53:43.620 --> 01:53:46.040
Great, thank you for that question, Henry.
01:53:46.040 --> 01:53:48.610
At this point, we have reached the end
01:53:48.610 --> 01:53:52.179
of the time block for our
question and answer session.
01:53:52.179 --> 01:53:54.210
To all three of the presenters,
01:53:54.210 --> 01:53:57.967
thank you so much for presenting
your guys's risk assessment
01:53:57.967 --> 01:53:59.783
and mapping and resource allocation.
01:54:00.730 --> 01:54:03.270
We will now take a short break here.
01:54:03.270 --> 01:54:07.930
We are going to resume at 11:35.
01:54:07.930 --> 01:54:10.410
The next section will be moderated
01:54:10.410 --> 01:54:12.890
by my colleague, Andy Biggs, and is...
01:54:12.890 --> 01:54:14.690
As part of properly assessing risk,
01:54:14.690 --> 01:54:16.710
it's vital that the utilities have frequent
01:54:16.710 --> 01:54:18.870
and thorough inspections
to understand asset health
01:54:18.870 --> 01:54:21.110
and accurately identify
where to conduct repairs
01:54:21.110 --> 01:54:23.580
replacements, and system hardening projects.
01:54:23.580 --> 01:54:24.920
Utilities need to demonstrate
01:54:24.920 --> 01:54:27.430
how they are identifying
advancements to the traditional
01:54:27.430 --> 01:54:29.440
from the ground and visual inspections
01:54:29.440 --> 01:54:31.910
whether it be through
drones, LiDAR, infra-red
01:54:31.910 --> 01:54:34.530
in order to augment inspections
and properly catch issues
01:54:34.530 --> 01:54:37.653
and field before they lead to an ignition.
01:54:38.840 --> 01:54:39.950
Integrating and understanding
01:54:39.950 --> 01:54:42.030
of equipment and asset
health utility should be vetting
01:54:42.030 --> 01:54:44.090
various mitigation measures to implement
01:54:44.090 --> 01:54:45.130
to reduce the risks posed
01:54:45.130 --> 01:54:47.910
by their systems, including PSPS risk.
01:54:47.910 --> 01:54:49.130
One of the higher bill options
01:54:49.130 --> 01:54:50.140
for mitigation will be digging
01:54:50.140 --> 01:54:51.860
into deeper the session grid hardening,
01:54:51.860 --> 01:54:54.030
which includes cover conductor undergrounding
01:54:54.030 --> 01:54:55.480
and microgrid development.
01:54:55.480 --> 01:54:57.530
Given the largely rural nature from much
01:54:57.530 --> 01:55:00.330
of the SNG's customer basis.
01:55:00.330 --> 01:55:01.163
With climate change
01:55:01.163 --> 01:55:03.410
and weather conditions
worsening over the past few years,
01:55:03.410 --> 01:55:04.980
utilities should be building their systems
01:55:04.980 --> 01:55:07.040
to be able to withstand
known local conditions
01:55:07.040 --> 01:55:10.320
to ensure systems won't
fail or lead to an ignition event
01:55:11.800 --> 01:55:12.920
at high wind speeds
01:55:12.920 --> 01:55:14.980
and focus on maintaining a reliable system
01:55:14.980 --> 01:55:18.250
that minimizes PSPS events and keeps power
01:55:18.250 --> 01:55:20.210
and lights on for customers.
01:55:20.210 --> 01:55:22.070
With that I'll turn it over to the utilities
01:55:22.070 --> 01:55:25.730
with 10 minutes each
starting off with the same order
01:55:25.730 --> 01:55:28.240
as earlier with PacifiCorp starting off,
01:55:28.240 --> 01:55:30.500
then Liberty, then Bear Valley.
01:55:30.500 --> 01:55:32.480
We'll also include the
01:55:32.480 --> 01:55:35.310
two independent transmission
operators this session,
01:55:35.310 --> 01:55:37.990
being Verizon West and Trans Bay Cable,
01:55:37.990 --> 01:55:39.760
even though they have
a much smaller footprint,
01:55:39.760 --> 01:55:41.460
they've still undergone
the work to understand
01:55:41.460 --> 01:55:44.290
and mitigate loss higher
risk along their systems.
01:55:44.290 --> 01:55:46.430
As a reminder, if you have any questions,
01:55:46.430 --> 01:55:47.780
please enter them into the chat
01:55:47.780 --> 01:55:49.710
for a moderator our Ryan Arbor to go through,
01:55:49.710 --> 01:55:51.280
and we'll have them answered
01:55:51.280 --> 01:55:53.593
during the Q&A session this afternoon.
01:56:00.650 --> 01:56:01.650
Okay, great.
01:56:02.800 --> 01:56:04.100
Can everyone hear me okay?
01:56:09.339 --> 01:56:10.172
Yep.
01:56:10.172 --> 01:56:11.390
Hello.
01:56:11.390 --> 01:56:13.080
Yep, you're coming in loud and clear.
01:56:13.080 --> 01:56:15.480
Yep, okay, (laughs loudly)
01:56:15.480 --> 01:56:18.333
Sorry, I'm so paranoid about that, thank you.
01:56:19.830 --> 01:56:20.790
So thanks for that, Andy.
01:56:20.790 --> 01:56:21.710
I assume you want me to go ahead
01:56:21.710 --> 01:56:23.410
and kick it off with PacifiCorp?
01:56:24.890 --> 01:56:26.370
Yes, please, go ahead.
01:56:26.370 --> 01:56:28.220
Yep, okay, great, thank you.
01:56:28.220 --> 01:56:29.580
So my name is Amy McCluskey,
01:56:29.580 --> 01:56:32.270
I'm the Director of Asset
Management at PacifiCorp.
01:56:32.270 --> 01:56:35.860
And today I will be presenting
to you on three key elements
01:56:35.860 --> 01:56:38.290
of our wildfire mitigation plans.
01:56:38.290 --> 01:56:39.950
These are grid hardening inspections
01:56:39.950 --> 01:56:41.520
and emerging technology.
01:56:41.520 --> 01:56:42.923
Next slide, please.
01:56:45.440 --> 01:56:47.210
And here they are again with a few images
01:56:47.210 --> 01:56:49.380
to give a little color.
01:56:49.380 --> 01:56:52.190
Specifically grid hardening, this is the area
01:56:52.190 --> 01:56:54.600
where we're talking about changing our grid.
01:56:54.600 --> 01:56:56.400
A huge portion of that is implementation
01:56:56.400 --> 01:56:58.470
of covered conductor grid.
01:56:58.470 --> 01:56:59.650
Inspections, we're gonna focus
01:56:59.650 --> 01:57:02.960
on both standard as well
as enhanced inspections.
01:57:02.960 --> 01:57:05.000
And then the last, the emerging technology.
01:57:05.000 --> 01:57:08.690
And we've added this
in because this is an area
01:57:08.690 --> 01:57:10.760
where we're testing out some new things
01:57:10.760 --> 01:57:11.910
and trying out some new things.
01:57:11.910 --> 01:57:13.730
And there's a high potential
01:57:13.730 --> 01:57:16.700
that what comes out of this
area can strongly influence how
01:57:16.700 --> 01:57:19.810
or what we do in grid
hardening and inspections.
01:57:19.810 --> 01:57:20.700
Throughout the presentation,
01:57:20.700 --> 01:57:23.757
I may refer to these as pilot
projects or research projects,
01:57:23.757 --> 01:57:26.960
and you may have seen
them in the WMP also referred
01:57:26.960 --> 01:57:29.410
to as different names,
but here we're gonna talk
01:57:29.410 --> 01:57:31.233
about them as emerging technologies.
01:57:32.340 --> 01:57:33.290
Next slide, please.
01:57:37.400 --> 01:57:41.310
So before we dive in, I did
wanna provide a quick refresher
01:57:41.310 --> 01:57:43.303
into our plan objectives.
01:57:44.830 --> 01:57:46.890
The walk through this it's not meant to,
01:57:46.890 --> 01:57:50.010
I would say replace the
detailed work that Heidi walked
01:57:50.010 --> 01:57:52.300
you through this morning on risk modeling.
01:57:52.300 --> 01:57:54.800
It's really here to just
provide a simplified view
01:57:54.800 --> 01:57:56.950
of what our plan hopes to accomplish
01:57:56.950 --> 01:57:59.310
and how our initiatives are designed
01:57:59.310 --> 01:58:01.030
to meet those objectives
01:58:01.030 --> 01:58:03.430
with an overall eye on reducing wildfire
01:58:03.430 --> 01:58:05.980
through the implementation of our WMP.
01:58:05.980 --> 01:58:06.820
So if you take a look here,
01:58:06.820 --> 01:58:10.410
we've got four objectives on the slide.
01:58:10.410 --> 01:58:13.280
So greater resilience or fewer fault events,
01:58:13.280 --> 01:58:16.880
rapid fault response,
facilitate situational awareness,
01:58:16.880 --> 01:58:20.650
and operational readiness and
consider and mitigate impacts
01:58:20.650 --> 01:58:22.870
to customers and communities.
01:58:22.870 --> 01:58:26.370
And when I think about why
certain mitigation activities,
01:58:26.370 --> 01:58:29.660
it really boiled down to
meeting these objectives
01:58:29.660 --> 01:58:32.470
and reducing risk by
observing the risk drivers
01:58:32.470 --> 01:58:34.240
that Heidi talked about this morning
01:58:34.240 --> 01:58:37.723
and trying to really change
the way our system operates.
01:58:38.890 --> 01:58:39.880
What I'd like you to take away
01:58:39.880 --> 01:58:43.084
from this slide is each of
our initiatives is designed
01:58:43.084 --> 01:58:47.210
around meeting a plan
objective, and therefore can
01:58:47.210 --> 01:58:50.133
either reduce risk or
enable the reduction of risk.
01:58:52.290 --> 01:58:55.330
And while each individual
component can be very effective
01:58:55.330 --> 01:58:56.980
where we really start to see benefit is
01:58:56.980 --> 01:58:58.990
when we combine initiatives
01:58:58.990 --> 01:59:02.300
or layer them on in these high risk areas.
01:59:02.300 --> 01:59:05.200
And as an example,
I'll just walk through one,
01:59:05.200 --> 01:59:07.500
when I think about that first plan objective,
01:59:07.500 --> 01:59:09.630
greater resilience
through fewer fault events.
01:59:09.630 --> 01:59:12.380
Do you remember from this
morning, Heidi walked through
01:59:14.422 --> 01:59:16.500
our fire risk event data
01:59:16.500 --> 01:59:19.403
that tells us we've got
two fairly large categories,
01:59:20.640 --> 01:59:22.130
one is contact with objects
01:59:22.130 --> 01:59:24.730
and another is equipment failure.
01:59:24.730 --> 01:59:25.970
But I think about grid hardening,
01:59:25.970 --> 01:59:28.390
and I think about trying to
reduce those fault events,
01:59:28.390 --> 01:59:31.700
it certainly checks that first
box of reducing the impact
01:59:31.700 --> 01:59:35.340
of contact, but it doesn't
necessarily check the box
01:59:35.340 --> 01:59:38.980
of reducing risks due to equipment failure.
01:59:38.980 --> 01:59:41.500
However, that's where our
asset inspections can really come
01:59:41.500 --> 01:59:44.580
into play and handle
that second risk reduction.
01:59:44.580 --> 01:59:45.870
So when you're in areas
01:59:45.870 --> 01:59:47.980
where you have multiple risk drivers,
01:59:47.980 --> 01:59:50.247
you need multiple initiatives.
01:59:50.247 --> 01:59:52.750
The last row there, emerging technology,
01:59:52.750 --> 01:59:54.790
certainly, we're still in test phase
01:59:54.790 --> 01:59:56.870
with a lot of our different pilot projects.
01:59:56.870 --> 01:59:59.300
So they're all kind of under construction,
01:59:59.300 --> 02:00:01.390
but I did wanna point out
that when we do develop
02:00:01.390 --> 02:00:03.020
these pilot projects, we're thinking
02:00:03.020 --> 02:00:06.620
about how these projects
can meet these objectives
02:00:06.620 --> 02:00:09.600
and how these projects
can inform other initiatives
02:00:09.600 --> 02:00:11.350
'cause that's what it's
all about is is sticking
02:00:11.350 --> 02:00:12.893
with our vision and our plan.
02:00:14.220 --> 02:00:15.600
Next slide, please.
02:00:17.770 --> 02:00:19.680
Now, that I've covered
a little bit of the why,
02:00:19.680 --> 02:00:22.430
I did want to touch on
the wheres just in case
02:00:22.430 --> 02:00:25.720
there are those who may
not be particularly familiar
02:00:25.720 --> 02:00:29.340
with our service territory,
got a map here on the left,
02:00:29.340 --> 02:00:30.950
just a few of the general stats.
02:00:30.950 --> 02:00:34.820
We provide electricity to
approximately 45,000 customers
02:00:34.820 --> 02:00:39.060
via 63 substations, just over 2,500 miles
02:00:39.060 --> 02:00:42.700
of distribution and about
800 miles of transmission.
02:00:42.700 --> 02:00:46.790
And our service territory spans
around 11,000 square miles.
02:00:46.790 --> 02:00:49.830
So it's a fairly low customer
density as compared
02:00:49.830 --> 02:00:52.440
to some of the other California utilities.
02:00:52.440 --> 02:00:55.270
Specific to the HPD or higher risk assets,
02:00:55.270 --> 02:00:58.586
we have the stats here on
the right hand of the slide,
02:00:58.586 --> 02:01:01.410
approximately 1200 miles, or just over 1/3
02:01:01.410 --> 02:01:04.520
of our overhead lines are within the HFTD,
02:01:04.520 --> 02:01:08.420
850 of those distribution
and 350 transmission.
02:01:08.420 --> 02:01:10.080
So this will become a little bit important
02:01:10.080 --> 02:01:13.550
when I'll get to later slides
to talk about where we deploy
02:01:13.550 --> 02:01:16.960
our different initiatives, what we look for,
02:01:16.960 --> 02:01:19.233
certainly these HFTD high risk areas
02:01:19.233 --> 02:01:22.170
as well as the one Heidi talked
about this morning become
02:01:22.170 --> 02:01:24.070
very, very critical to the deployment.
02:01:25.530 --> 02:01:26.480
Next slide, please.
02:01:29.620 --> 02:01:32.600
All right, so we've talked
about the why and the where.
02:01:32.600 --> 02:01:34.850
And so now, we'll start to get into the what.
02:01:35.900 --> 02:01:38.170
This slide here, it's all
about our grid design
02:01:38.170 --> 02:01:40.502
and system hardening initiative.
02:01:40.502 --> 02:01:43.220
As I put her on the slides
02:01:43.220 --> 02:01:48.220
about four main areas where
we focused on system hardening,
02:01:48.430 --> 02:01:51.140
bursting installation of coverage conductor,
02:01:51.140 --> 02:01:53.590
second proactive replacement of poles,
02:01:53.590 --> 02:01:55.660
installation of system equipment,
02:01:55.660 --> 02:01:58.430
and replacement of small diameter conductor.
02:01:58.430 --> 02:02:01.310
I've also included in
this view the installation
02:02:01.310 --> 02:02:02.393
of weather stations.
02:02:03.410 --> 02:02:07.090
It's not strictly a grid design
system hardening initiative
02:02:07.090 --> 02:02:09.810
but it's such an important
part of how we deploy,
02:02:09.810 --> 02:02:12.960
how we manage the work
that we have included it here
02:02:12.960 --> 02:02:14.650
because it's such a critical component
02:02:14.650 --> 02:02:16.280
of the overall program.
02:02:16.280 --> 02:02:18.600
However, if you were to dig into the WMP,
02:02:18.600 --> 02:02:20.930
you would see it under situational awareness.
02:02:20.930 --> 02:02:23.690
I did just want to note that
in case you're trying to follow
02:02:23.690 --> 02:02:25.840
along with the document,
it's just not gonna follow
02:02:25.840 --> 02:02:27.893
in order with the other components here.
02:02:30.870 --> 02:02:34.660
When I think about the
the initiatives here and why,
02:02:34.660 --> 02:02:37.210
why covered conductor, why replacing a pole?
02:02:37.210 --> 02:02:40.320
The first one that touched
on earlier covered conductor is
02:02:40.320 --> 02:02:43.940
really around limiting the impact of contact.
02:02:43.940 --> 02:02:46.333
So it's preventing the event altogether.
02:02:47.740 --> 02:02:51.660
The other three on here
focus on a few different things.
02:02:51.660 --> 02:02:54.820
So they focus more on controlling the event
02:02:54.820 --> 02:02:57.160
or making sure the event doesn't get worse.
02:02:57.160 --> 02:02:59.560
So they mitigate risks slightly differently.
02:02:59.560 --> 02:03:02.910
For example, the proactive
replacement of poles.
02:03:02.910 --> 02:03:07.910
For that program PacifiCorp
is targeting high risk locations
02:03:08.060 --> 02:03:10.570
that might be susceptible to a brush fire
02:03:10.570 --> 02:03:11.780
where we think we could use
02:03:11.780 --> 02:03:14.820
some additional structural
resilience to make sure
02:03:14.820 --> 02:03:18.193
that restoration can be
faster to support egress.
02:03:19.639 --> 02:03:23.037
So it's not really a program
that prevents an event,
02:03:23.037 --> 02:03:25.033
but it helps control it and make sure
02:03:25.033 --> 02:03:27.253
that it can be recovered from quickly.
02:03:28.420 --> 02:03:29.263
The last year of installation
02:03:29.263 --> 02:03:31.920
with system automation
equipment and replacement
02:03:31.920 --> 02:03:34.080
of small diameter conductors,
02:03:34.080 --> 02:03:35.800
they have a similar goal in mind,
02:03:35.800 --> 02:03:38.500
which is our ability to
implement advanced protection
02:03:38.500 --> 02:03:40.100
and control schemes.
02:03:40.100 --> 02:03:42.390
So system automation
equipment, that's all your widgets,
02:03:42.390 --> 02:03:45.320
your relays, your reclosers,
your circuit breakers,
02:03:45.320 --> 02:03:47.750
your advanced communication equipment
02:03:47.750 --> 02:03:52.320
that allow us to identify a
fault faster, see smarter,
02:03:52.320 --> 02:03:55.870
isolate quicker and really
reduce the potential energy
02:03:55.870 --> 02:03:57.840
that can be released.
02:03:57.840 --> 02:04:01.470
Replacement a small
diameter conductor is an enabler
02:04:01.470 --> 02:04:03.770
to that program, so we have a few areas
02:04:04.900 --> 02:04:07.430
where we need additional capabilities.
02:04:07.430 --> 02:04:08.440
And in order to do that,
02:04:08.440 --> 02:04:12.173
we have to upgrade the
small diameter conductor first.
02:04:14.170 --> 02:04:15.930
I've included some numbers on here,
02:04:15.930 --> 02:04:19.200
total program targets as
well as annual program targets
02:04:20.350 --> 02:04:22.020
as opposed to going through
those 'cause sometimes,
02:04:22.020 --> 02:04:24.770
it can be challenging to
figure out what they need
02:04:24.770 --> 02:04:27.680
and if they're good, I've
included a qualitative phasing
02:04:27.680 --> 02:04:29.720
and deployment graph on the right.
02:04:29.720 --> 02:04:31.970
And I just wanna point out just a few things.
02:04:33.670 --> 02:04:36.160
There are no units for this qualitative
02:04:36.160 --> 02:04:38.800
and along the x-axis are the years
02:04:38.800 --> 02:04:42.750
and then the colors do
correspond to the programs.
02:04:42.750 --> 02:04:45.220
And you can kind of see in 2019,
02:04:45.220 --> 02:04:47.980
we started focusing on weather stations
02:04:47.980 --> 02:04:50.840
and system automation and plan development.
02:04:50.840 --> 02:04:53.340
In 2020, again to shift efforts
02:04:53.340 --> 02:04:55.460
and ramp up our covered conductor program,
02:04:55.460 --> 02:04:58.380
focused on design, and
engineering, and scope.
02:04:58.380 --> 02:05:00.530
And now, we're pretty much fully ramped up
02:05:00.530 --> 02:05:03.830
and focusing on high-risk PSPS mitigation,
02:05:03.830 --> 02:05:05.740
which includes pairing different initiatives
02:05:05.740 --> 02:05:06.960
in a specific location,
02:05:06.960 --> 02:05:09.323
which I'll walk you
through in the next slide.
02:05:10.630 --> 02:05:12.530
Our plan is to continue with that,
02:05:12.530 --> 02:05:14.403
but I did wanna point out, sorry.
02:05:17.040 --> 02:05:18.740
Can you go back one slide, please?
02:05:21.420 --> 02:05:24.260
Toward the very right,
you see, it says risk shifts.
02:05:24.260 --> 02:05:28.650
To date, we've been
focused on PSPS locations,
02:05:28.650 --> 02:05:30.490
but as Heidi walked you
through the risk modeling
02:05:30.490 --> 02:05:33.930
this morning, as that evolves
and we get more granular
02:05:33.930 --> 02:05:35.967
with our risk and exactly
where our high risks are
02:05:35.967 --> 02:05:38.660
and what locations specific drivers are,
02:05:38.660 --> 02:05:40.900
there is the potential that we may change
02:05:40.900 --> 02:05:43.110
how we target programs and where,
02:05:43.110 --> 02:05:45.300
but right now you can kind of
see where we are in the graph.
02:05:45.300 --> 02:05:48.473
We're really focused on PSPS mitigation.
02:05:49.510 --> 02:05:50.593
Okay, next slide.
02:05:54.450 --> 02:05:58.130
This is just a quick snapshot
of what that looks like.
02:05:58.130 --> 02:06:00.993
I don't expect you to read
everything on the left here,
02:06:01.840 --> 02:06:03.540
but I'm gonna point out a couple of things.
02:06:03.540 --> 02:06:05.160
So this is an example of focusing
02:06:05.160 --> 02:06:08.000
in on the high-risk PSPS location,
02:06:08.000 --> 02:06:10.480
and there is some color
coding that is important.
02:06:10.480 --> 02:06:13.240
The color coding on the
circuitry kind of describes
02:06:13.240 --> 02:06:15.610
how we might bucket the different work.
02:06:15.610 --> 02:06:17.300
So where we have isolation
02:06:17.300 --> 02:06:19.490
or where things are electrically connected.
02:06:19.490 --> 02:06:21.730
And what we do is we look color by color
02:06:21.730 --> 02:06:24.060
and say, "What are the things we can do here
02:06:24.060 --> 02:06:25.550
to mitigate risk?"
02:06:25.550 --> 02:06:28.160
I'm up with an implementation
plan, which is what you see
02:06:28.160 --> 02:06:30.180
on the left, which is kind of a color section
02:06:30.180 --> 02:06:32.630
by color section, how
we're attacking that portion
02:06:32.630 --> 02:06:33.530
or that circuit.
02:06:33.530 --> 02:06:36.410
And it is once you
complete your constructions,
02:06:36.410 --> 02:06:39.530
then you would have mitigated the PSPS risk
02:06:39.530 --> 02:06:41.260
in this location.
02:06:41.260 --> 02:06:44.870
So as opposed to looking at all the places
02:06:44.870 --> 02:06:47.170
you might have covered
conductor or all the places
02:06:47.170 --> 02:06:50.480
you might have reclosers,
we're looking at what lists,
02:06:50.480 --> 02:06:53.960
what menu items of our
system hardening do I need
02:06:53.960 --> 02:06:57.533
in this PSPS location to
mitigate the PSPS risk.
02:06:59.920 --> 02:07:00.870
Next slide, please.
02:07:04.390 --> 02:07:05.890
Now, we'll shift gears a little bit.
02:07:05.890 --> 02:07:08.890
So moving from a grid
design and system hardening
02:07:08.890 --> 02:07:11.870
to inspection, that here, when I talked
02:07:11.870 --> 02:07:13.890
to you through our
standard inspection programs
02:07:13.890 --> 02:07:16.040
as well as our enhanced inspection program.
02:07:16.900 --> 02:07:19.320
On the last, in 2021,
02:07:19.320 --> 02:07:23.840
our goal is to complete
63,000 cyclical inspections.
02:07:23.840 --> 02:07:27.820
These are typically driven
by compliance requirements.
02:07:27.820 --> 02:07:31.890
So for us, it's just a around
3,000 intrusive inspections
02:07:31.890 --> 02:07:35.020
where we also typically
perform a detail at the same time.
02:07:35.020 --> 02:07:37.560
So it's kind of a double inspection,
02:07:37.560 --> 02:07:41.560
10,000 additional detail and
around 50,000 visual assurance
02:07:41.560 --> 02:07:42.963
versus the inspection.
02:07:44.030 --> 02:07:46.660
In addition to just performing
the body of the work,
02:07:46.660 --> 02:07:48.970
our goal is to complete the tier two
02:07:48.970 --> 02:07:51.630
and tier three inspections
prior to fire season,
02:07:51.630 --> 02:07:53.930
making sure we focus
on those high risk areas.
02:07:55.840 --> 02:07:57.990
Additionally, identify fire threat conditions
02:07:57.990 --> 02:07:59.840
and accelerate corrections.
02:07:59.840 --> 02:08:03.380
If 2021 is anything like 2020,
02:08:03.380 --> 02:08:06.880
we think we will be finding
around 8,800 conditions,
02:08:06.880 --> 02:08:08.570
800 of which will be fire threats
02:08:08.570 --> 02:08:11.000
that we need to accelerate correction for.
02:08:11.000 --> 02:08:12.100
So that's what we're planning on.
02:08:12.100 --> 02:08:15.220
We'll see how the numbers
shake out when it's all done.
02:08:15.220 --> 02:08:17.997
And finally, another goal we have is to bring
02:08:17.997 --> 02:08:21.430
you a fresh focus to our
QA/QC of inspections.
02:08:21.430 --> 02:08:23.170
This is an area we received feedback
02:08:23.170 --> 02:08:26.207
on and think like we could,
02:08:26.207 --> 02:08:29.210
it was important that we
really focus on this area.
02:08:29.210 --> 02:08:32.210
So for us, that means
incorporate fire risk identification
02:08:32.210 --> 02:08:35.250
into annual training,
prioritize the tier three
02:08:35.250 --> 02:08:38.900
and tier two locations,
complete desktop reviews.
02:08:38.900 --> 02:08:42.340
We're planning for around
6,500 of those this year
02:08:42.340 --> 02:08:46.240
as well as around just under
700 field inspection audits
02:08:46.240 --> 02:08:49.050
as well, so that's their standard program.
02:08:49.050 --> 02:08:52.293
When I move over to enhanced program here,
02:08:53.180 --> 02:08:56.480
for us right now, that means
our infra-red inspections have
02:08:56.480 --> 02:08:58.590
overhead transmission lines.
02:08:58.590 --> 02:09:01.080
This was something we kicked off in 2019,
02:09:01.080 --> 02:09:05.933
has evolved in 2020, and
it's now a full program in 2021.
02:09:06.810 --> 02:09:10.240
I believe to date, we've
found seven different hotspots
02:09:10.240 --> 02:09:11.703
on our transmission lines.
02:09:13.080 --> 02:09:14.880
At first it was one or two
02:09:14.880 --> 02:09:17.240
and I think we learned a lot over the years
02:09:17.240 --> 02:09:19.150
that we really need to target the inspections
02:09:19.150 --> 02:09:22.600
when the lines are more heavily loaded, peak,
02:09:22.600 --> 02:09:24.290
or near peak loading,
02:09:24.290 --> 02:09:27.260
so that gives us the best possible diagnosis
02:09:27.260 --> 02:09:30.830
or the best possible chance
to see that extra hotspot.
02:09:30.830 --> 02:09:32.930
An example of one of
those is tear on this slide
02:09:32.930 --> 02:09:36.863
that was abnormal heating on
a jumper on a 69 KV structured.
02:09:38.090 --> 02:09:40.083
And one of the big things in 2021
02:09:40.083 --> 02:09:43.240
that we've introduced the new
program management processes
02:09:43.240 --> 02:09:45.560
and procedures, so we have better tracking
02:09:45.560 --> 02:09:49.590
to describe program
effectiveness, program costs
02:09:49.590 --> 02:09:52.230
'cause we do see this as
something that is supplemental
02:09:52.230 --> 02:09:53.920
and in addition to our standard programs,
02:09:53.920 --> 02:09:56.376
we wanna make sure we're
measuring the effectiveness
02:09:56.376 --> 02:09:57.209
as we go.
02:09:58.545 --> 02:09:59.462
Next slide.
02:10:02.283 --> 02:10:04.970
So this is the last topic I'll cover today,
02:10:04.970 --> 02:10:07.030
and I know a lot on the slide.
02:10:07.030 --> 02:10:08.630
So I'll kinda touch on a few things,
02:10:08.630 --> 02:10:12.150
this is emerging technology
or our pilot projects,
02:10:12.150 --> 02:10:14.240
you will find a lot more detailed information
02:10:14.240 --> 02:10:19.240
in the 2021 WMP, specifically section 4.4.1.
02:10:19.800 --> 02:10:22.330
I picked the six tier to
just draw on the slide
02:10:22.330 --> 02:10:24.000
and talk through a little bit.
02:10:24.000 --> 02:10:28.400
With each, we've got the
name, very very brief description,
02:10:28.400 --> 02:10:30.820
the application, which is really how I see
02:10:30.820 --> 02:10:34.740
this pilot project
influencing something else,
02:10:34.740 --> 02:10:36.860
the plan objectives, so does it align
02:10:36.860 --> 02:10:39.870
with one of our plan
objectives I walked you through?
02:10:39.870 --> 02:10:40.870
And then the status.
02:10:42.200 --> 02:10:44.070
The first one distributed fault anticipation
02:10:44.070 --> 02:10:45.770
in wave form analysis.
02:10:45.770 --> 02:10:48.100
This is a partnership with Texas A&M
02:10:48.100 --> 02:10:49.627
to install new devices on circuits
02:10:49.627 --> 02:10:53.490
and see if we can get
smarter about predicting faults.
02:10:53.490 --> 02:10:55.480
So obviously, if you think
about the plan objectives,
02:10:55.480 --> 02:11:00.480
it's predicting faults and
ensuring rapid full response.
02:11:02.110 --> 02:11:03.780
The LiDAR or pole loading assessment program,
02:11:03.780 --> 02:11:06.650
we've got two LiDAR programs on up here.
02:11:06.650 --> 02:11:10.860
One focuses on assets, the
other one focuses on vegetation
02:11:10.860 --> 02:11:13.900
'cause the first one is really
around leveraging data to see
02:11:13.900 --> 02:11:15.810
if we can improve how we model circuits,
02:11:15.810 --> 02:11:17.070
how we understand risk,
02:11:17.070 --> 02:11:19.613
and how we identify
equipment for replacement.
02:11:20.570 --> 02:11:22.930
The LiDAR vegetation,
which I believe will be touched
02:11:22.930 --> 02:11:25.590
on a little bit later this afternoon is
02:11:25.590 --> 02:11:28.340
around informing risk mapping
02:11:28.340 --> 02:11:31.543
and potential threats
that exist on the system.
02:11:33.100 --> 02:11:36.170
The fourth pilot here,
radio-frequency and infra-red
02:11:36.170 --> 02:11:37.670
for line patrolman, it takes a lot
02:11:37.670 --> 02:11:39.490
of the positive things we've learned
02:11:39.490 --> 02:11:42.180
from our existing in Hampton session program
02:11:42.180 --> 02:11:45.750
and explores whether
or not we can incorporate
02:11:45.750 --> 02:11:48.490
those elements into our
standard inspection programs.
02:11:48.490 --> 02:11:51.300
Certainly still in the early
stages there, but hoping
02:11:51.300 --> 02:11:53.460
that we can take a lot of
already existing lessons learned
02:11:53.460 --> 02:11:54.383
and apply them.
02:11:55.290 --> 02:11:58.010
The arc energy fault modeling project,
02:11:58.010 --> 02:11:59.150
this has been really critical
02:11:59.150 --> 02:12:02.460
as the company has advanced
the risk modeling efforts.
02:12:02.460 --> 02:12:03.580
So being able to simulate
02:12:03.580 --> 02:12:05.860
and calculate the potential arc energy
02:12:05.860 --> 02:12:08.750
certainly helped us
understand where our risks are.
02:12:08.750 --> 02:12:09.583
And then finally,
02:12:09.583 --> 02:12:12.870
the advanced weather
station modeling project,
02:12:12.870 --> 02:12:14.710
which is about comparing different types
02:12:14.710 --> 02:12:16.220
of weather stations.
02:12:16.220 --> 02:12:18.220
So the company is certainly adamant
02:12:18.220 --> 02:12:21.100
about deploying weather
stations for situational awareness.
02:12:21.100 --> 02:12:23.200
We're just not sure exactly which one yet.
02:12:24.896 --> 02:12:26.490
And so with all of these,
02:12:26.490 --> 02:12:27.750
we're trying to keep a close eye
02:12:27.750 --> 02:12:30.040
on how they inform other programs,
02:12:30.040 --> 02:12:32.340
how they change our risk modeling,
02:12:32.340 --> 02:12:35.083
and how they meet the
different plan objectives.
02:12:36.870 --> 02:12:41.427
One more slide, and so what
that does is say, thank you,
02:12:41.427 --> 02:12:45.317
and I appreciate the attention
and thanks for listening.
02:12:49.140 --> 02:12:50.960
Yeah, thank you so much, Amy.
02:12:50.960 --> 02:12:52.380
Up next we have Liberty
02:12:59.344 --> 02:13:01.080
This is Dylan Harris with Liberty.
02:13:01.080 --> 02:13:02.810
Could you bring the slide deck up, please?
02:13:02.810 --> 02:13:03.953
Great, thank you.
02:13:07.090 --> 02:13:11.340
And I believe it is halfway roughly through
02:13:11.340 --> 02:13:16.340
this presentation is where
my piece starts after this,
02:13:16.500 --> 02:13:17.893
right there, perfect.
02:13:19.210 --> 02:13:21.950
Hello, everyone, thanks for being here today.
02:13:21.950 --> 02:13:23.920
My name is Dylan Harris,
I'm an electrical engineer
02:13:23.920 --> 02:13:25.980
with the operations
department here at Liberty.
02:13:25.980 --> 02:13:27.980
I'm here today to discuss
02:13:27.980 --> 02:13:31.060
with you Liberty's grid
design, system hardening,
02:13:31.060 --> 02:13:33.620
inspections, and mitigation choices
02:13:33.620 --> 02:13:36.913
within the 2021 WMP update.
02:13:38.260 --> 02:13:42.760
Obviously, that's a mouthful
and just a lot of topics
02:13:42.760 --> 02:13:46.170
to cover a pretty wide
breadth of information here.
02:13:46.170 --> 02:13:49.970
So I'm just gonna try
and hit on the key points
02:13:49.970 --> 02:13:50.903
of each of these.
02:13:52.800 --> 02:13:55.410
We really have a wide array of approaches
02:13:55.410 --> 02:13:57.573
for grid design and system hardening.
02:13:58.410 --> 02:14:02.300
Everything from coverage
conductors to micro grid projects.
02:14:02.300 --> 02:14:03.390
We just started this year
02:14:03.390 --> 02:14:05.980
as well as some substation hardening efforts.
02:14:05.980 --> 02:14:08.130
And then we've also made great strides
02:14:08.130 --> 02:14:12.750
in improving our inspections in 2021.
02:14:12.750 --> 02:14:13.700
Next slide, please.
02:14:16.800 --> 02:14:20.820
So in 2020, we completed our
first cover conductor projects.
02:14:20.820 --> 02:14:24.130
We now have seven miles of covered conductor
02:14:24.130 --> 02:14:27.390
roughly installed within
our service territory.
02:14:27.390 --> 02:14:30.000
The majority of that is this ACS
02:14:30.000 --> 02:14:32.433
or aerial conductors system type,
02:14:33.600 --> 02:14:35.180
construction that you see here
02:14:35.180 --> 02:14:38.130
where the conductor is
sort of bundled together
02:14:38.130 --> 02:14:41.003
and supported by a messenger wire.
02:14:42.290 --> 02:14:45.390
In future years, we plan to
use risk mapping and modeling
02:14:45.390 --> 02:14:49.470
to drive where we really want
to implement covered conductor
02:14:49.470 --> 02:14:51.320
and other grid hardening initiatives.
02:14:52.590 --> 02:14:54.330
So far some challenges we've faced
02:14:54.330 --> 02:14:58.960
with the coverage conductive
program are permitting issues,
02:14:58.960 --> 02:15:01.550
visual impact, and initially we had
02:15:01.550 --> 02:15:05.210
some unfamiliar maintenance practices
02:15:05.210 --> 02:15:07.910
and tools due to it just
being a new construction type
02:15:08.916 --> 02:15:13.520
within our company, we've
since held some trainings
02:15:13.520 --> 02:15:15.460
and gotten the right tools.
02:15:15.460 --> 02:15:18.300
And we've largely bridge that gap
02:15:18.300 --> 02:15:21.730
of the big question is how do we,
02:15:21.730 --> 02:15:26.150
if a tree totally falls through
this and breaks everything,
02:15:26.150 --> 02:15:31.023
how do we address that type
of catastrophic style of outage?
02:15:34.230 --> 02:15:36.830
Another area where we're targeting
02:15:36.830 --> 02:15:39.870
with the use of cover conductor is creation
02:15:39.870 --> 02:15:41.940
of resiliency corridors.
02:15:41.940 --> 02:15:45.930
So the idea here is we have
some existing generation
02:15:45.930 --> 02:15:49.270
assets specifically within
our North Lake Tahoe
02:15:49.270 --> 02:15:53.410
service territory that
in the event of a PSPS,
02:15:53.410 --> 02:15:56.100
we can create this resiliency corridor
02:15:56.100 --> 02:15:58.980
with covered conductor,
shut down portions of the grid
02:15:58.980 --> 02:16:03.610
that we need to, but have
confidence that a key area
02:16:03.610 --> 02:16:07.280
of the service territory
is going to have power
02:16:07.280 --> 02:16:11.490
during these PSPS events
and give the community a place
02:16:11.490 --> 02:16:14.540
to be during one of these events
02:16:14.540 --> 02:16:17.163
and have critical services available.
02:16:18.800 --> 02:16:21.350
And conductor is a good technology,
02:16:21.350 --> 02:16:24.750
but we were continuing
to evaluate alternatives.
02:16:24.750 --> 02:16:25.700
Next slide, please.
02:16:28.340 --> 02:16:32.850
So among those alternatives
is as microgrids 2020,
02:16:32.850 --> 02:16:34.440
we were successful in constructing
02:16:34.440 --> 02:16:37.520
and Commissioning
our first microgrid solution
02:16:37.520 --> 02:16:40.760
to a remote mountain research station.
02:16:40.760 --> 02:16:43.403
It is the Sagehen Creek Field Station,
02:16:44.410 --> 02:16:46.920
kind of Northwest of Truckee
02:16:46.920 --> 02:16:49.101
if you're familiar with the area.
02:16:49.101 --> 02:16:52.170
These projects save have
customers over $2 million
02:16:52.170 --> 02:16:54.860
by replacing high fire risk distribution line
02:16:54.860 --> 02:16:58.217
with a containerized solar
plus battery storage microgrid,
02:16:59.840 --> 02:17:01.780
the line is it's still physically in place
02:17:01.780 --> 02:17:04.200
but we have the ability
to totally deenergized
02:17:04.200 --> 02:17:06.597
it during fire season.
02:17:08.340 --> 02:17:11.370
Additionally, we're
undergoing feasibility studies
02:17:11.370 --> 02:17:13.430
for microgrids and other locations,
02:17:13.430 --> 02:17:16.540
we have planned covered conductor projects
02:17:16.540 --> 02:17:20.430
that we're looking, taking
a step back and saying,
02:17:20.430 --> 02:17:23.650
it doesn't make more
sense to do a microgrid here,
02:17:23.650 --> 02:17:26.630
what is the feasibility
from a cost perspective
02:17:26.630 --> 02:17:30.378
and what does that
bias in terms of resiliency
02:17:30.378 --> 02:17:32.543
and value for the customer?
02:17:33.470 --> 02:17:34.520
Next slide, please.
02:17:38.970 --> 02:17:42.800
So in 2020, we did a system wide inventory
02:17:42.800 --> 02:17:44.480
of all our overhead assets.
02:17:44.480 --> 02:17:48.270
This kind of serves the
baseline of our system condition
02:17:48.270 --> 02:17:50.580
and we can use this to develop programs
02:17:50.580 --> 02:17:53.623
to proactively replace infrastructure.
02:17:54.510 --> 02:17:58.100
So this system inventory really allows us
02:17:58.100 --> 02:18:01.810
rather than just having a
time-based maintenance program
02:18:01.810 --> 02:18:06.320
to evaluate the condition
today of every piece
02:18:06.320 --> 02:18:09.670
of equipment in our overhead inventory
02:18:09.670 --> 02:18:11.150
and kind of create a
02:18:11.150 --> 02:18:14.190
more condition-based maintenance program,
02:18:14.190 --> 02:18:16.890
which is it's something
that's really exciting for us.
02:18:18.410 --> 02:18:20.363
And go ahead, go to the next slide.
02:18:24.010 --> 02:18:27.510
So another outcome of
the system inventory was
02:18:27.510 --> 02:18:30.270
also application-based inspection.
02:18:30.270 --> 02:18:32.280
So believe it or not,
02:18:32.280 --> 02:18:37.280
in 2019 Liberty was using
paper-based GO165 inspection forms
02:18:38.830 --> 02:18:42.070
and that just doesn't have the granularity
02:18:42.070 --> 02:18:44.620
and quality of data that you need
02:18:46.450 --> 02:18:48.110
from what the Commission is asking for,
02:18:48.110 --> 02:18:51.370
so we drastically improved that in 2020
02:18:52.730 --> 02:18:54.770
and also completed inspections
02:18:54.770 --> 02:18:56.433
on the entire overhead system.
02:18:57.620 --> 02:19:00.350
So this improved inspection practice,
02:19:00.350 --> 02:19:03.340
like I was mentioning in
the previous slide provides
02:19:03.340 --> 02:19:08.000
prioritization for mitigation
of at-risk structures.
02:19:08.000 --> 02:19:12.160
So when you take this
asset condition combining
02:19:12.160 --> 02:19:15.350
with the risk mapping and modeling effort
02:19:15.350 --> 02:19:17.940
that Greg spoke about this morning,
02:19:17.940 --> 02:19:22.880
you really get a really
solid way to prioritize
02:19:25.630 --> 02:19:26.613
system maintenance.
02:19:27.840 --> 02:19:30.070
And then future years, we're looking
02:19:30.070 --> 02:19:33.000
at expanding our inspection program
02:19:33.000 --> 02:19:37.840
to include infra-red imagery
in and seeing the applications
02:19:37.840 --> 02:19:39.693
that that can have for us.
02:19:41.310 --> 02:19:42.640
Next slide, please.
02:19:47.120 --> 02:19:49.163
So a couple of emerging technologies
02:19:49.163 --> 02:19:51.113
that we wanna talk about today,
02:19:52.780 --> 02:19:55.877
PacifiCorp mentioned
distribution fall anticipation.
02:19:55.877 --> 02:20:00.330
And so the idea here is
you look at high fidelity,
02:20:00.330 --> 02:20:02.310
current and voltage wave forms,
02:20:02.310 --> 02:20:05.810
and Texas A&M has developed algorithms
02:20:05.810 --> 02:20:10.810
that can reliably detect, this nuance looks
02:20:11.050 --> 02:20:13.410
like it might be a branch hitting the tree
02:20:13.410 --> 02:20:17.670
or it might be a failed
connector or something days
02:20:17.670 --> 02:20:22.670
or weeks before an actual
outage or failure occurs,
02:20:23.150 --> 02:20:25.983
which obviously has really big impacts.
02:20:27.130 --> 02:20:29.490
So we don't have this deployed yet
02:20:29.490 --> 02:20:33.270
within our service territory within 2021,
02:20:33.270 --> 02:20:37.680
we'll have approximately
20% of the feeders covered.
02:20:37.680 --> 02:20:42.680
And this is starting in our
very high wildfire risk areas.
02:20:43.200 --> 02:20:47.530
So we're using that at risk
mapping to prioritize this work
02:20:49.070 --> 02:20:50.910
and kind of in, since we don't have
02:20:50.910 --> 02:20:53.710
this technology deployed,
yet, we sort of have to look
02:20:53.710 --> 02:20:57.640
at at other resources for,
hey, how effective is this?
02:20:57.640 --> 02:21:01.220
And so we've looked at
FTE's wildfire mitigation plan
02:21:01.220 --> 02:21:05.110
and they've deemed it successful enough
02:21:05.110 --> 02:21:07.270
to drastically expand this program.
02:21:07.270 --> 02:21:10.420
And so that's something we're looking
02:21:10.420 --> 02:21:15.220
at as an indication that
is a promising technology.
02:21:17.410 --> 02:21:22.410
Additionally, the initial
risk analysis is favorable
02:21:23.170 --> 02:21:27.100
and cost-effective based
on the fact that it is relatively
02:21:27.100 --> 02:21:30.900
easy to install, hardware
wise, just a single piece
02:21:30.900 --> 02:21:33.280
of equipment for each feeder.
02:21:33.280 --> 02:21:36.380
And so we're looking to expand
02:21:36.380 --> 02:21:39.273
that as a cost effective mitigation solution.
02:21:40.280 --> 02:21:41.230
Next slide, please.
02:21:46.960 --> 02:21:48.010
Lastly, I'll touch
02:21:48.010 --> 02:21:51.420
quickly on our distribution
automation program
02:21:51.420 --> 02:21:56.420
that we target the designed
to be complete within this year.
02:21:56.620 --> 02:21:59.850
Again, we're targeting theaters
02:21:59.850 --> 02:22:02.810
and the very high fire risk areas.
02:22:02.810 --> 02:22:06.380
And in terms of reducing the risk of,
02:22:06.380 --> 02:22:09.180
and scope of PSPS events as part of this,
02:22:09.180 --> 02:22:11.920
we're adding a lot of sectionalizing options
02:22:13.590 --> 02:22:16.790
to really limit that scope
as much as we can combine
02:22:16.790 --> 02:22:21.790
with data from our weather
stations and circuit monitoring,
02:22:23.230 --> 02:22:26.800
we can really make the most
informed decision possible
02:22:26.800 --> 02:22:28.950
to try and limit the scope of those events.
02:22:30.120 --> 02:22:32.170
And distribution automation,
02:22:32.170 --> 02:22:34.178
like I mentioned is gonna leverage
02:22:34.178 --> 02:22:38.740
some new technology as
well as existing reclosers
02:22:38.740 --> 02:22:42.720
and isolation devices
that we have in the field.
02:22:42.720 --> 02:22:45.000
And it also is a great improvement
02:22:45.000 --> 02:22:46.923
to the system reliability.
02:22:49.150 --> 02:22:53.933
And with that, that is all
I have today, thank you.
02:22:58.890 --> 02:23:00.390
Thank you so much.
02:23:00.390 --> 02:23:02.763
Up next is Scott, Bear Valley presentation.
02:23:18.810 --> 02:23:19.643
Okay,
02:23:22.660 --> 02:23:24.810
most of my slides will talk
02:23:24.810 --> 02:23:28.643
about the grid hardening aspects.
02:23:29.650 --> 02:23:32.280
I'll talk about inspections, although a lot
02:23:32.280 --> 02:23:35.600
of slides are in the next section
02:23:35.600 --> 02:23:38.690
where I can explain those further.
02:23:38.690 --> 02:23:40.740
And then on emerging technology,
02:23:40.740 --> 02:23:43.660
they'll talk about that as well at the end.
02:23:43.660 --> 02:23:45.093
Go to the next slide.
02:23:49.286 --> 02:23:52.447
When you look at grid design and hardening,
02:23:52.447 --> 02:23:54.973
it's important to understand the environment.
02:23:56.060 --> 02:23:59.450
It's a small area, 32 square miles,
02:23:59.450 --> 02:24:04.450
it's about 7,000 feet is
where most of the facilities are.
02:24:04.450 --> 02:24:05.283
So it's
02:24:07.870 --> 02:24:10.700
in the heavy loading district.
02:24:10.700 --> 02:24:11.600
For those of you familiar
02:24:11.600 --> 02:24:15.380
with geo 95 constructional requirements.
02:24:15.380 --> 02:24:20.300
And then it's also all within
the high fire threat district,
02:24:20.300 --> 02:24:25.300
mostly about 90% tier
two, about a 10% tier three.
02:24:29.890 --> 02:24:34.500
And key jurisdictions, it's
really three principle ones,
02:24:34.500 --> 02:24:37.780
the County of San Bernandino,
City of Big Bear Lake
02:24:37.780 --> 02:24:39.383
and US Forest Reserves.
02:24:44.790 --> 02:24:48.560
Most of our voltages are
either sub-transmission
02:24:48.560 --> 02:24:53.337
or distribution
sub-transmission at 34,500 volts,
02:24:55.100 --> 02:24:56.803
distribution 4kV.
02:24:58.260 --> 02:24:59.510
You go to the next slide.
02:25:02.160 --> 02:25:05.450
I'm gonna highlight some of the projects
02:25:05.450 --> 02:25:10.450
we've embarked on, covered
wire conductor installation is
02:25:12.520 --> 02:25:14.003
something we've embraced.
02:25:14.870 --> 02:25:17.910
We did pilot the program last year
02:25:19.840 --> 02:25:23.700
and selected two vendors Priority Wire
02:25:23.700 --> 02:25:29.500
and the South Wire
products, we tested others
02:25:29.500 --> 02:25:32.950
and our decision was to go with these two
02:25:32.950 --> 02:25:36.453
as the principle solutions.
02:25:37.693 --> 02:25:40.423
And we do have a pretty ambitious program.
02:25:41.660 --> 02:25:45.973
We got about eight
circuit miles last year and
02:25:48.930 --> 02:25:53.370
we plan on doing about 13 circuit miles
02:25:53.370 --> 02:25:55.948
per year going forward.
02:25:55.948 --> 02:26:00.760
And that's split between
4.3 circuit miles per year
02:26:00.760 --> 02:26:02.410
on the subtransmission side
02:26:02.410 --> 02:26:06.453
and 8.6 circuit miles distribution.
02:26:08.760 --> 02:26:13.760
And this is all targeted
on a prioritized list using
02:26:14.860 --> 02:26:16.973
that fire safety matrix,
02:26:18.080 --> 02:26:21.213
so to decide where to go, where to do it.
02:26:22.660 --> 02:26:25.003
So that's how that's driven.
02:26:29.176 --> 02:26:31.133
You can go to the next slide.
02:26:33.980 --> 02:26:35.790
Just one comment.
02:26:35.790 --> 02:26:38.113
The covered conductor is a long-term project,
02:26:39.040 --> 02:26:41.560
but as we target those high risk areas,
02:26:41.560 --> 02:26:44.843
obviously, we start getting
starting early payoffs.
02:26:47.410 --> 02:26:52.410
Fuse replacement program,
this project started in 2019.
02:26:53.690 --> 02:26:57.913
The objective was to remove
conventional expulsion fuses.
02:26:59.847 --> 02:27:04.490
As you can see, fuse events
are spark producing events
02:27:04.490 --> 02:27:08.493
that could potentially
result in fire or wildfire.
02:27:10.090 --> 02:27:14.323
And the nice thing about,
this is an early win, I think.
02:27:16.050 --> 02:27:21.050
We had a little over
3200 fuses in our system.
02:27:21.160 --> 02:27:25.540
We came up with a strategy
to use current limiting fuses
02:27:25.540 --> 02:27:27.257
and TripSavers
02:27:30.030 --> 02:27:32.653
and a strategy on where to put each.
02:27:37.207 --> 02:27:41.374
As of 31 December, we
had 901 remaining to replace
02:27:44.206 --> 02:27:47.956
and our goals to have a system by June, 2021.
02:27:53.560 --> 02:27:56.960
And one of the things
like, for example, last year
02:27:58.280 --> 02:28:01.390
we had, I think, 22
02:28:03.160 --> 02:28:04.580
fuse events
02:28:05.810 --> 02:28:09.160
and because of the progress
we had made in this project,
02:28:09.160 --> 02:28:13.393
I think only three of those
events were conventional fuses.
02:28:14.810 --> 02:28:19.210
So just shows we've reduced that risk
02:28:20.260 --> 02:28:23.513
by getting this done and
getting it done quickly.
02:28:26.618 --> 02:28:31.618
So that to me has been a good
project and reasonable costs.
02:28:35.410 --> 02:28:36.860
You can go to the next slide.
02:28:40.686 --> 02:28:42.650
As you can see, evacuation hardening,
02:28:42.650 --> 02:28:44.440
I talked a little bit
02:28:44.440 --> 02:28:47.393
when I asked one of the questions last panel.
02:28:48.300 --> 02:28:51.170
In picture, there's basically three ways
02:28:51.170 --> 02:28:53.203
off the mountain on paved roads.
02:28:54.670 --> 02:28:57.300
And so it's very important
02:28:57.300 --> 02:29:02.133
that we keep the poles
from falling into the road,
02:29:02.980 --> 02:29:07.000
and obviously there's
different ways of handling that.
02:29:07.000 --> 02:29:12.000
So we piloted to make sure
we were familiar and understood.
02:29:12.180 --> 02:29:15.700
What's involved with the different solutions
02:29:15.700 --> 02:29:17.563
on different types of poles.
02:29:19.513 --> 02:29:21.760
Obviously, we were underground before.
02:29:21.760 --> 02:29:26.023
In fact, a good portions
coincided with an evacuation route.
02:29:27.950 --> 02:29:32.700
We evaluate what's the cost
of relocating infrastructure
02:29:33.870 --> 02:29:36.640
and then we've looked at
this wire mesh cladding wrap
02:29:38.260 --> 02:29:40.820
and we looked at what
other utilities are doing.
02:29:40.820 --> 02:29:45.220
And once we saw that they
had adopted certain solutions,
02:29:45.220 --> 02:29:47.090
we went out and tried them ourselves
02:29:48.601 --> 02:29:51.450
or talk to them to make sure we understood
02:29:52.350 --> 02:29:55.250
so that we could get the
benefit of what they had learned.
02:29:57.480 --> 02:30:00.550
So, as I mentioned, our plan is
02:30:00.550 --> 02:30:03.500
to harden the three main
evacuation routes over two years
02:30:05.560 --> 02:30:08.130
and using the wire mesh wraps
02:30:08.130 --> 02:30:12.280
that quickly gets a handle on the problem.
02:30:12.280 --> 02:30:17.280
And then we develop a policy
to replace the wood poles.
02:30:17.280 --> 02:30:19.613
When they're being
replaced for any other reason,
02:30:19.613 --> 02:30:24.613
we do it with something
that's fire resistant and so forth.
02:30:26.900 --> 02:30:31.900
This is anecdotal, but I
think it's key to understand.
02:30:33.360 --> 02:30:37.923
If you did have a wildfire in Big Bear Lake,
02:30:42.710 --> 02:30:45.947
any region, generally
you'll find at least one
02:30:45.947 --> 02:30:50.730
of the evacuation routes is
closed down due to the fire.
02:30:50.730 --> 02:30:52.840
Just if you look at the geography
02:30:53.880 --> 02:30:57.560
that's the fact that's generally true.
02:30:57.560 --> 02:31:00.190
And most fires that have threatened us
02:31:00.190 --> 02:31:04.630
in recent years have threatened
02:31:04.630 --> 02:31:08.180
at least one evacuation route.
02:31:08.180 --> 02:31:09.960
Last summer, there was a fire.
02:31:09.960 --> 02:31:14.340
They were inner dark territory,
but it shut down Highway 38
02:31:16.360 --> 02:31:19.080
and a number of the scenarios
02:31:20.030 --> 02:31:21.260
that the
02:31:22.180 --> 02:31:25.840
Cal Fire and the
District Commander ran
02:31:25.840 --> 02:31:29.720
if the fire had spread up
the backside of the mountains
02:31:29.720 --> 02:31:32.820
up to Big Bear Lake, it would have taken away
02:31:34.440 --> 02:31:36.470
the area near the dam over to the left
02:31:36.470 --> 02:31:40.070
on that chart Highway 18 over there.
02:31:40.070 --> 02:31:43.763
So we would have been left
with one route down to return.
02:31:44.600 --> 02:31:47.850
So it's very important that we focus
02:31:47.850 --> 02:31:51.570
on these evacuation routes and understand
02:31:53.531 --> 02:31:56.040
the weaknesses that they cause
02:31:57.600 --> 02:32:00.393
that we contribute positively
to making them safe.
02:32:04.320 --> 02:32:05.770
You can go to the next slide.
02:32:08.050 --> 02:32:12.260
So obviously, we use our risk modeling
02:32:12.260 --> 02:32:17.260
to develop our prioritize
list of mitigations.
02:32:17.870 --> 02:32:19.940
But at a higher level, like I said,
02:32:19.940 --> 02:32:23.653
we're mostly tier two, a
small portion tier three.
02:32:24.870 --> 02:32:26.743
So we sorta have to prioritize.
02:32:28.675 --> 02:32:31.923
Unlike the larger utilities, we have to get
02:32:32.900 --> 02:32:35.863
even more granular than
the high fire threat districts.
02:32:37.640 --> 02:32:39.580
And so we're a little more surgical,
02:32:39.580 --> 02:32:41.470
we've identified high risk circuits
02:32:44.330 --> 02:32:49.330
and we consider these
things as we develop our plans.
02:32:52.500 --> 02:32:56.880
One of the things that, I don't
have it up here on the slide
02:32:56.880 --> 02:33:01.677
because we've already
sectionalized our high risk areas
02:33:03.660 --> 02:33:06.910
and so from a PSPS perspective,
02:33:06.910 --> 02:33:08.380
we've already got that in place.
02:33:08.380 --> 02:33:13.220
The next level is automating
those particular switches,
02:33:13.220 --> 02:33:14.370
which is what we're doing.
02:33:14.370 --> 02:33:16.480
We have a grid automation project,
02:33:16.480 --> 02:33:17.900
which is in progress right now.
02:33:17.900 --> 02:33:20.250
They're installing a fiber network
02:33:20.250 --> 02:33:22.380
that'll allow us to do that.
02:33:22.380 --> 02:33:26.110
But once again, 32 square
mile area, it's not hard
02:33:26.110 --> 02:33:29.420
for our crews during
the high-risk fire weather
02:33:29.420 --> 02:33:33.043
to be out in the field
and get those switches.
02:33:33.960 --> 02:33:35.800
We haven't had to do that.
02:33:35.800 --> 02:33:38.530
We do exercise having the mountain fields
02:33:38.530 --> 02:33:39.683
in order to do that,
02:33:42.720 --> 02:33:44.751
but we are fully sectionalized
02:33:44.751 --> 02:33:46.723
to where we wanna be right now.
02:33:48.890 --> 02:33:53.470
On the inspection, we, first of all, do the,
02:33:53.470 --> 02:33:58.470
obviously, the geo 165
required periodicities.
02:34:00.820 --> 02:34:04.900
Due to our location, we
do annual ground patrols,
02:34:04.900 --> 02:34:06.960
we do five-year detailed inspection,
02:34:06.960 --> 02:34:09.283
we do the intrusive pole inspections.
02:34:11.040 --> 02:34:15.990
We also, in addition to the ground patrol,
02:34:15.990 --> 02:34:20.990
we do a second annual
ground patrol by a third-party.
02:34:21.810 --> 02:34:26.810
So this is another contractor independent
02:34:27.060 --> 02:34:30.610
of our field inspector and we make sure
02:34:30.610 --> 02:34:33.220
that contractor has no
construction work with us.
02:34:33.220 --> 02:34:37.503
So they're completely
focused on inspection and
02:34:40.720 --> 02:34:45.720
that's a good check and it
helps us get that outside view.
02:34:45.750 --> 02:34:47.240
Then we also use LiDAR.
02:34:47.240 --> 02:34:50.020
We've now completed two LiDAR surveys
02:34:50.020 --> 02:34:52.100
and we're trying to do the LiDAR per year.
02:34:52.100 --> 02:34:55.760
And I think that's a very
good effective program.
02:34:57.740 --> 02:35:02.130
We did do tomography route
02:35:02.130 --> 02:35:07.130
our entire area using Brown
mounted two years ago
02:35:07.710 --> 02:35:09.683
and it didn't yield a whole lot,
02:35:12.023 --> 02:35:15.220
so we have increased the periodicity on that.
02:35:16.390 --> 02:35:19.940
And right now we're looking
where we've got an RFP out
02:35:19.940 --> 02:35:23.870
to contract out a UAV where we will get
02:35:23.870 --> 02:35:28.870
some high definition imagery and
02:35:31.110 --> 02:35:32.523
thermal imaging as well.
02:35:33.550 --> 02:35:38.550
So we're excited about
using that inspection technique
02:35:38.730 --> 02:35:41.763
to help identify areas for improvement.
02:35:42.970 --> 02:35:44.820
Likewise, we're in the process
02:35:44.820 --> 02:35:49.540
of implementing a inspection app for patrol
02:35:51.120 --> 02:35:53.950
our field inspector so that we get
02:35:55.950 --> 02:35:56.783
highly accurate
02:35:56.783 --> 02:36:01.360
and automate the process
of identifying deficiencies
02:36:01.360 --> 02:36:04.983
in getting into our GIS system.
02:36:06.560 --> 02:36:09.890
One of the things too, that it's not
02:36:09.890 --> 02:36:12.730
in our wildfire mitigation
plan this time round
02:36:12.730 --> 02:36:15.480
but it's something we're
talking about and considering,
02:36:16.590 --> 02:36:21.590
detailed inspections by Geo165
are required every five years
02:36:23.490 --> 02:36:24.853
on all circuits.
02:36:26.650 --> 02:36:28.710
It doesn't matter if they're underground,
02:36:28.710 --> 02:36:32.073
overhead, bare conductor,
overhead, covered conductor,
02:36:33.260 --> 02:36:36.160
it's a five-year inspection.
02:36:36.160 --> 02:36:38.710
So we split it up each year
we do a certain number.
02:36:40.760 --> 02:36:42.013
Having worked in other communities
02:36:42.013 --> 02:36:45.490
such as the nuclear field
and petrochemical field,
02:36:45.490 --> 02:36:48.493
those areas they do, what's
called risk=based inspection.
02:36:49.650 --> 02:36:51.820
So we might adopt a plan
02:36:51.820 --> 02:36:54.720
where you more frequently inspect the higher,
02:36:54.720 --> 02:36:56.963
the bare wire, and high-risk areas,
02:36:59.870 --> 02:37:00.703
and so forth.
02:37:00.703 --> 02:37:04.030
So you develop a periodicity based on that.
02:37:04.030 --> 02:37:07.120
So that's something we're trying to focus on
02:37:08.180 --> 02:37:13.030
so that treating underground systems,
02:37:13.030 --> 02:37:15.770
which are fairly stable
and reliable, the same
02:37:15.770 --> 02:37:20.410
as a bare wire and tier three area is
02:37:21.370 --> 02:37:25.720
probably not the correct
answer on detailed inspections.
02:37:25.720 --> 02:37:28.743
And so that's something we're
gonna address in the future.
02:37:30.900 --> 02:37:33.263
Regarding emerging technologies,
02:37:35.730 --> 02:37:39.517
we pilot programs that
have already shown promise
02:37:41.550 --> 02:37:43.360
at other utilities.
02:37:43.360 --> 02:37:46.870
Being a small train, the technology risk
02:37:46.870 --> 02:37:51.870
for our customer base is a lot.
02:37:52.700 --> 02:37:55.370
And so we don't wanna buy into something
02:37:55.370 --> 02:37:58.730
that's gonna turn out to not work.
02:37:58.730 --> 02:38:03.480
So we tend to leverage
work with the big utilities
02:38:03.480 --> 02:38:08.160
and then apply it tomorrow
unique circumstances.
02:38:08.160 --> 02:38:12.980
And we think that's a very cost effective way
02:38:12.980 --> 02:38:16.390
of getting these new
technologies into our system
02:38:16.390 --> 02:38:21.390
in a fairly responsible and
yet decision fast manner.
02:38:22.230 --> 02:38:26.680
We also are open to folks
who wanna do research
02:38:26.680 --> 02:38:29.350
on our environment and our systems.
02:38:29.350 --> 02:38:33.223
We certainly are open to
collaboration in those areas.
02:38:35.090 --> 02:38:36.210
That's all I have.
02:38:39.440 --> 02:38:41.617
Great, thank you so much, Scott.
02:38:41.617 --> 02:38:44.620
I'm gonna transition over into the ICU
02:38:44.620 --> 02:38:46.170
starting off with Horizon West.
02:38:50.590 --> 02:38:51.423
Thank you, Andy.
02:38:51.423 --> 02:38:54.627
This is all I see on this Horizon West to me.
02:38:54.627 --> 02:38:55.960
Can you hear me?
02:38:57.481 --> 02:38:59.110
Yeah, I can you hear me?
02:38:59.110 --> 02:39:00.590
Okay, great.
02:39:00.590 --> 02:39:02.700
So I know we're running short on time,
02:39:02.700 --> 02:39:04.603
so I'll be pretty brief here.
02:39:05.560 --> 02:39:07.490
But like I said, my name is Alona Sias,
02:39:07.490 --> 02:39:10.256
I'm Director of Strategy
and Business Development
02:39:10.256 --> 02:39:12.800
and I represent Horizon West Transmission.
02:39:12.800 --> 02:39:14.863
So we can go on to the next page.
02:39:16.470 --> 02:39:17.920
In terms of the agenda for today,
02:39:17.920 --> 02:39:21.510
so before we get into the
wildfire mitigation strategies
02:39:21.510 --> 02:39:24.200
and measures and section, TNN said
02:39:24.200 --> 02:39:26.940
we are employing at
Horizon West transmission,
02:39:26.940 --> 02:39:30.040
I wanted to spend just a few
minutes to give an overview
02:39:30.040 --> 02:39:31.800
of Horizon West Transmission, given that
02:39:31.800 --> 02:39:36.800
we're very new independent
transmission owner in California
02:39:37.010 --> 02:39:40.947
and I wanted to give an
understanding of our footprint
02:39:40.947 --> 02:39:44.620
and our current scope
of operations in the state.
02:39:44.620 --> 02:39:46.360
And then after that, we're gonna talk
02:39:46.360 --> 02:39:48.010
through the specific measures we're taking
02:39:48.010 --> 02:39:51.620
that we detailed in our 2021 WMP
02:39:51.620 --> 02:39:54.370
before the harden and the
assets that we have in space.
02:39:55.290 --> 02:39:56.883
Let's go to the next page.
02:39:59.500 --> 02:40:02.390
So like I said, we were a very new utility.
02:40:02.390 --> 02:40:04.220
We were transmission only utility
02:40:04.220 --> 02:40:07.010
and we were the first
non-incumbents to be awarded
02:40:07.010 --> 02:40:08.830
to competitive transmission project
02:40:08.830 --> 02:40:11.390
by the kites bill back in 2015.
02:40:11.390 --> 02:40:14.670
And those two projects are
the Suncrest SVC project,
02:40:14.670 --> 02:40:16.970
which is in Southern California
02:40:16.970 --> 02:40:19.077
interconnecting as the SDG&E.
02:40:20.210 --> 02:40:21.177
And then the second project is
02:40:21.177 --> 02:40:24.901
the Estrella substation
projects interconnecting
02:40:24.901 --> 02:40:26.793
SDG&E in Northern California.
02:40:27.670 --> 02:40:29.690
So both of these projects were awarded to us
02:40:29.690 --> 02:40:32.760
as part of FERC Order 1000 process.
02:40:32.760 --> 02:40:35.640
And both of these are
very contained substations,
02:40:35.640 --> 02:40:38.921
so they're limited transmission lines
02:40:38.921 --> 02:40:40.713
and no distribution line.
02:40:41.920 --> 02:40:42.820
Next page, please.
02:40:47.260 --> 02:40:49.570
So like I said, the only
projects we currently have
02:40:49.570 --> 02:40:52.490
in operation is the Suncrest project,
02:40:52.490 --> 02:40:55.930
which is in Southern
California and is located
02:40:55.930 --> 02:41:00.310
in tier three wildfire area, it's
interconnected with SDG&E
02:41:00.310 --> 02:41:04.070
and it's about 40 miles East of San Diego,
02:41:04.070 --> 02:41:08.543
and of course, in San Diego
County near the Town of Alpine.
02:41:09.710 --> 02:41:11.080
It's a very new asset.
02:41:11.080 --> 02:41:13.310
It's a little bit over a year old.
02:41:13.310 --> 02:41:16.640
So we energized that early last year
02:41:17.490 --> 02:41:20.550
and we have not had
any utility-caused ignitions,
02:41:20.550 --> 02:41:22.940
near misses, or PSPS events
02:41:22.940 --> 02:41:25.803
at the Suncrest SVC project to date.
02:41:27.110 --> 02:41:28.640
And the project was selected
02:41:28.640 --> 02:41:31.000
to provide reactive power support
02:41:31.000 --> 02:41:36.000
and increase, enabled more
renewables being transmitted
02:41:36.830 --> 02:41:39.363
from Imperial Valley
into the rest of the system.
02:41:40.759 --> 02:41:42.259
And let's go to the next page.
02:41:44.940 --> 02:41:48.550
And then once again, this
is the location of the project
02:41:48.550 --> 02:41:53.010
and relation to the high
fire threat district area.
02:41:53.010 --> 02:41:57.447
So you can see it's in
a higher fire district area
02:41:57.447 --> 02:41:59.780
secure three, and we've had a history
02:41:59.780 --> 02:42:02.610
of fostering wildfires, especially last year,
02:42:02.610 --> 02:42:06.320
there was the valley fire
being very close to RS at
02:42:06.320 --> 02:42:07.823
as close as four miles away.
02:42:09.280 --> 02:42:10.193
Next page, please.
02:42:14.420 --> 02:42:16.550
I want to spend a ton of time here.
02:42:16.550 --> 02:42:20.483
This is just another deep
dive into the project location.
02:42:21.480 --> 02:42:22.880
Let's get to the next slide.
02:42:27.310 --> 02:42:29.470
Okay, so on this slide,
02:42:29.470 --> 02:42:32.820
you can see exactly
the project overview here.
02:42:32.820 --> 02:42:37.820
So on the right hand side,
this is the project location,
02:42:38.750 --> 02:42:40.870
sorry, it looks like the
font is a little blurry,
02:42:40.870 --> 02:42:42.900
but that's specifically, thank you,
02:42:42.900 --> 02:42:44.880
that's the project location itself.
02:42:44.880 --> 02:42:47.280
The blue line that you can see from
02:42:47.280 --> 02:42:51.970
that project location is the
underground spot one mile line
02:42:51.970 --> 02:42:54.620
and gone into as the SDG&E substation.
02:42:54.620 --> 02:42:58.570
And then the tiny green
line is a very short span
02:42:58.570 --> 02:43:01.013
of overhead wire transmission lines
02:43:01.013 --> 02:43:03.883
that we're currently
working on undergrounding.
02:43:05.020 --> 02:43:06.030
So, like I said, this is just
02:43:06.030 --> 02:43:08.820
to give you sort of an
understanding of the scope
02:43:08.820 --> 02:43:10.320
of operations that we have
02:43:13.800 --> 02:43:17.360
and we're making sure that
our wildfire mitigation plan is
02:43:17.360 --> 02:43:19.210
really tailored to our current scope
02:43:19.210 --> 02:43:21.723
and footprint of operations in California.
02:43:23.670 --> 02:43:24.620
Thank you for that, and then.
02:43:24.620 --> 02:43:26.773
I think we can go to the next page.
02:43:31.351 --> 02:43:33.570
And then in terms of to give you a visual of
02:43:33.570 --> 02:43:34.720
what the project looks like,
02:43:34.720 --> 02:43:37.840
this has been main SPC
facilities static are compensated.
02:43:37.840 --> 02:43:39.600
This is a substation itself
02:43:39.600 --> 02:43:42.970
like that is being connected to SDG&E
02:43:42.970 --> 02:43:46.720
through the about one mile
underground transmission line.
02:43:46.720 --> 02:43:49.610
And as you can see,
there's really no vegetation
02:43:51.547 --> 02:43:53.130
around the substation and make sure
02:43:53.130 --> 02:43:56.581
that the original design
was hardscaped taking
02:43:56.581 --> 02:43:59.290
into account the high risk of wildfire
02:43:59.290 --> 02:44:01.710
in the area where we have the assets.
02:44:01.710 --> 02:44:05.610
So we're really done a
great job of just thinking
02:44:05.610 --> 02:44:07.520
through the original design and making sure
02:44:07.520 --> 02:44:10.610
that we make those modifications early on
02:44:10.610 --> 02:44:13.590
to minimize any contact with education
02:44:13.590 --> 02:44:16.693
that we have to minimize
any risk of ignition.
02:44:18.360 --> 02:44:19.853
So let's go to the next page.
02:44:22.280 --> 02:44:23.113
Okay, great, so
02:44:24.363 --> 02:44:26.710
now that everybody has a better understanding
02:44:26.710 --> 02:44:30.600
of our scope and operations in California,
02:44:30.600 --> 02:44:34.450
wanted to talk through
our approach to identifying
02:44:34.450 --> 02:44:36.370
for their harding measures and making sure
02:44:36.370 --> 02:44:40.400
that we are still keeping
wildfire risk top of mind
02:44:40.400 --> 02:44:43.140
and making sure that we are
protecting the infrastructure
02:44:43.140 --> 02:44:44.940
as best as possible.
02:44:44.940 --> 02:44:48.710
So we primarily employ a
failure modes and effects analysis,
02:44:48.710 --> 02:44:53.680
FMEA methodology to inform
appropriate wildfire hardening.
02:44:53.680 --> 02:44:55.980
This methodology was pioneered by NASA
02:44:55.980 --> 02:44:58.380
to identify potential failure modes
02:44:58.380 --> 02:45:00.580
and proactively address them.
02:45:00.580 --> 02:45:04.430
And really what we do, we
use this five step methodology
02:45:05.410 --> 02:45:08.880
to understand what is the underlying risk,
02:45:08.880 --> 02:45:12.000
quantify the risk, and then
based on that quantification,
02:45:12.000 --> 02:45:15.200
identify modification that
we should be implementing
02:45:16.520 --> 02:45:17.593
and implement those.
02:45:18.780 --> 02:45:19.613
So based on that,
02:45:19.613 --> 02:45:22.150
what we do is the first
step is the risk identification.
02:45:22.150 --> 02:45:26.960
So for each major component
of the equipment that we have
02:45:26.960 --> 02:45:29.590
whether it's being the
underground transmission line
02:45:29.590 --> 02:45:33.470
or the substation site itself or transformer,
02:45:33.470 --> 02:45:36.420
we go through every single
element trying to identify
02:45:37.603 --> 02:45:38.970
what are all the potential ways
02:45:38.970 --> 02:45:41.453
in which that equipment components may fail.
02:45:42.580 --> 02:45:45.010
And then based on that, we brainstorm
02:45:45.010 --> 02:45:47.270
what could be potential
drivers of the failure
02:45:47.270 --> 02:45:50.120
of that components, whether
it's concept of education
02:45:50.120 --> 02:45:54.210
or just equipment failure
or seismic events trying
02:45:54.210 --> 02:45:58.020
to be very holistic in our assessments.
02:45:58.020 --> 02:46:00.530
And then based on that, we prioritize,
02:46:00.530 --> 02:46:05.530
we assign a score in this
third step, risk prioritization.
02:46:05.580 --> 02:46:10.290
We think through how likely that event occur,
02:46:10.290 --> 02:46:14.430
what would be the impact
of that event occurrence
02:46:14.430 --> 02:46:16.270
to the severity of that pack,
02:46:16.270 --> 02:46:19.160
and then what measures
or capabilities do we have
02:46:19.160 --> 02:46:22.030
in place to detect that
event in case it does occur.
02:46:22.030 --> 02:46:25.430
So we can respond to
very drastically and quickly.
02:46:25.430 --> 02:46:29.520
And then based on that, we
calculate a risk clarity number.
02:46:29.520 --> 02:46:32.710
And after we've done that
exercise for each element,
02:46:32.710 --> 02:46:34.630
we go through the risk mitigation.
02:46:34.630 --> 02:46:38.060
So for any element that has starting
02:46:38.060 --> 02:46:40.840
with the highest risk
clarity number, we tried
02:46:40.840 --> 02:46:43.550
to brainstorm what
potential mitigation measures
02:46:43.550 --> 02:46:46.660
we should be deploying to minimize the risk
02:46:46.660 --> 02:46:47.900
of that elements failing
02:46:47.900 --> 02:46:51.840
and potentially creating
a utility cost ignition.
02:46:51.840 --> 02:46:53.960
And after we go through that entire exercise
02:46:53.960 --> 02:46:58.960
for the entire scope of our
asset, we do the risk assessment
02:46:58.990 --> 02:47:03.650
of reprioritization, sort of
going back and asking ourselves
02:47:03.650 --> 02:47:05.550
based on our mitigation
measure that we're going
02:47:05.550 --> 02:47:10.280
to implement, what is the
resulting risk priority number
02:47:10.280 --> 02:47:12.380
and do we need to do anything further
02:47:12.380 --> 02:47:15.883
to further reduce the risk?
02:47:17.260 --> 02:47:19.800
So that is the primary
methodology that we deploy
02:47:19.800 --> 02:47:23.993
to identify the right
initiatives for grid hardening.
02:47:24.930 --> 02:47:26.893
So let's go to the next page.
02:47:29.270 --> 02:47:31.620
And I think because we're
running a little short of time,
02:47:31.620 --> 02:47:32.970
I'll probably skip this one.
02:47:32.970 --> 02:47:35.150
Let's go to the following one where we go
02:47:35.150 --> 02:47:38.290
through the actual initiatives
we have identified for this.
02:47:38.290 --> 02:47:39.740
Thank you.
02:47:39.740 --> 02:47:42.820
So through that, like I
said, because after this new,
02:47:42.820 --> 02:47:46.430
we've had the benefit of
learning some best practices
02:47:46.430 --> 02:47:50.450
from all the other utilities
who've been doing the work
02:47:50.450 --> 02:47:53.730
on wildfire mitigation for
much longer than we have.
02:47:53.730 --> 02:47:56.227
We really took a lot of
these mitigation measures
02:47:56.227 --> 02:47:59.150
and implemented them in
their original facility design.
02:47:59.150 --> 02:48:02.573
So we thought through the
original design made sure
02:48:02.573 --> 02:48:06.440
that we are, for example,
under we undergrounded the line
02:48:06.440 --> 02:48:08.253
because tier three, we gonna sure
02:48:08.253 --> 02:48:10.940
that we have fuel free vegetation setbacks
02:48:10.940 --> 02:48:13.503
and there's no vegetation
within the site itself.
02:48:14.380 --> 02:48:16.300
If the project is located on land
02:48:16.300 --> 02:48:17.650
that has been previously discharged.
02:48:17.650 --> 02:48:20.900
So there's really very little vegetation
02:48:20.900 --> 02:48:24.440
and you did lean to the
surrounding area of the project.
02:48:24.440 --> 02:48:26.250
We also contracted fire support
02:48:26.250 --> 02:48:28.640
to the have on site during construction.
02:48:28.640 --> 02:48:31.330
So anytime you have a spark or hot work,
02:48:31.330 --> 02:48:33.810
you really minimize risk of ignition.
02:48:33.810 --> 02:48:37.600
And then in terms of the
hardening measures themselves
02:48:37.600 --> 02:48:41.680
that were implemented,
as you saw from the picture,
02:48:41.680 --> 02:48:44.430
we erected a concrete perimeter wall
02:48:44.430 --> 02:48:47.530
to minimize any ignitions or any arcs
02:48:47.530 --> 02:48:50.230
from the substation itself leading the site
02:48:50.230 --> 02:48:52.610
and igniting vegetation offsite.
02:48:52.610 --> 02:48:55.060
We're also implementing
transformer gas monitoring
02:48:55.060 --> 02:48:58.070
and containment hardening
to make sure that we have
02:48:58.070 --> 02:49:02.120
that real-time visibility to
the health of our transformers
02:49:02.120 --> 02:49:06.700
as potential oil leaks if
they were to occur also
02:49:06.700 --> 02:49:10.110
because the project is in
a seismically active area
02:49:10.110 --> 02:49:12.550
with transformer seismic pads.
02:49:12.550 --> 02:49:14.651
And then similar to a lot of other utilities,
02:49:14.651 --> 02:49:16.050
we're installing a weather station
02:49:16.050 --> 02:49:19.840
to just further enhance our
real time situational awareness
02:49:19.840 --> 02:49:22.803
of the site and cameras as well.
02:49:25.636 --> 02:49:27.940
So we can go to the next page.
02:49:30.830 --> 02:49:32.400
I have a couple more pages,
02:49:32.400 --> 02:49:35.030
but I think I'll end on this page.
02:49:35.030 --> 02:49:37.043
In terms of inspections and maintenance,
02:49:38.460 --> 02:49:43.460
we have the site is remotely monitored 24/7
02:49:43.600 --> 02:49:45.740
by qualified personnel
02:49:45.740 --> 02:49:48.320
through those all the
sensors that I talked about,
02:49:48.320 --> 02:49:51.020
but also the overhead cameras.
02:49:51.020 --> 02:49:53.890
In addition to that, we
do a detailed inspection
02:49:53.890 --> 02:49:55.890
of the sites on a monthly basis
02:49:55.890 --> 02:49:58.130
and that includes all sort of equipment,
02:49:58.130 --> 02:50:00.450
all fuel modification areas,
02:50:00.450 --> 02:50:05.450
just to make sure that
everything's in top shape.
02:50:06.330 --> 02:50:09.380
And then we also have
regular education as a tool
02:50:09.380 --> 02:50:11.730
to make sure that there's enough education
02:50:11.730 --> 02:50:13.850
that's encroaching on the site
02:50:13.850 --> 02:50:16.813
and can cause concept
with energized equipment.
02:50:18.740 --> 02:50:21.430
And then in terms of operational practices,
02:50:21.430 --> 02:50:23.490
we have the rest of my 40 protocol
02:50:24.440 --> 02:50:26.710
where we really don't do
02:50:26.710 --> 02:50:28.640
any non critical construction activities
02:50:28.640 --> 02:50:30.480
during red flag warning days given
02:50:30.480 --> 02:50:32.620
that those are much higher risk.
02:50:32.620 --> 02:50:36.130
We have hot work safety
program where any hot work
02:50:36.130 --> 02:50:40.630
that involves grading or
bark on the site is improvised.
02:50:40.630 --> 02:50:42.640
And then we have five safety training
02:50:42.640 --> 02:50:46.323
for all personnel including
contractors on site.
02:50:48.643 --> 02:50:50.373
You can go to the next page, please.
02:50:54.160 --> 02:50:56.623
And lastly, I'll briefly touch on these.
02:50:57.470 --> 02:50:59.930
Like I said, in terms of condition awareness,
02:50:59.930 --> 02:51:03.420
we have 24/7 monitoring.
02:51:03.420 --> 02:51:06.660
We have equipment health sensors
02:51:06.660 --> 02:51:09.410
that help us really be more proactive
02:51:09.410 --> 02:51:12.410
about understanding the
health of our critical pieces
02:51:12.410 --> 02:51:17.410
of equipment and rather than
reactive as problems come up.
02:51:17.700 --> 02:51:20.890
We have individualized
inspections that I talked about.
02:51:20.890 --> 02:51:22.640
And then in terms of response and recovery,
02:51:22.640 --> 02:51:26.260
we provided specific tailored training
02:51:26.260 --> 02:51:28.140
to local fire agencies.
02:51:28.140 --> 02:51:29.660
They're very familiar with the site,
02:51:29.660 --> 02:51:32.000
they know how to respond
to those electrical fires
02:51:32.000 --> 02:51:34.010
that were to happen there.
02:51:34.010 --> 02:51:37.620
We have an emergency response plan in place
02:51:37.620 --> 02:51:40.830
and we have all of our key
personnel trained on that.
02:51:40.830 --> 02:51:44.210
And in addition to that, we
have a private fire brigade
02:51:44.210 --> 02:51:46.730
that's dedicated to the Suncrest project
02:51:46.730 --> 02:51:50.060
in case there were ignition at a site
02:51:50.060 --> 02:51:52.330
to make sure that we have dedicated access
02:51:52.330 --> 02:51:55.130
to fire suppression
resources that are trained
02:51:55.130 --> 02:51:57.180
on electrical fires and are familiar
02:51:57.180 --> 02:51:58.543
with the layout of sites.
02:51:59.450 --> 02:52:02.060
And then, like I said, because
we are transmission only,
02:52:02.060 --> 02:52:03.630
we do not have MD's customers.
02:52:03.630 --> 02:52:06.660
We do not foresee ever deployed PSDS,
02:52:06.660 --> 02:52:09.630
but we do have a protocol to communicate
02:52:09.630 --> 02:52:14.107
with the stakeholders like CAISO, like SDG&E
02:52:14.107 --> 02:52:16.630
and in case we do have a need
02:52:16.630 --> 02:52:20.133
for a emergency communication procedure.
02:52:21.850 --> 02:52:24.520
So that's all I have for Horizon West.
02:52:24.520 --> 02:52:25.620
Thank you again for the time
02:52:25.620 --> 02:52:27.887
and thank you for all the input.
02:52:30.838 --> 02:52:32.170
Thank you so much, Alona.
02:52:32.170 --> 02:52:33.910
I know we're running a little bit over
02:52:33.910 --> 02:52:36.260
but we just have one more presentation
02:52:37.230 --> 02:52:40.223
with Trans Bay Cable and
then we'll break for lunch.
02:52:48.190 --> 02:52:49.070
Hello, this is Michael.
02:52:49.070 --> 02:52:49.903
Can you hear me?
02:52:52.400 --> 02:52:53.723
Yes, we can hear you, Michael.
02:52:54.570 --> 02:52:55.403
Hi.
02:52:57.140 --> 02:52:59.440
Well, thank you for having us here.
02:52:59.440 --> 02:53:02.990
So I'll be doing a quick
intro to Trans Bay Cable
02:53:02.990 --> 02:53:05.020
and then I'll hand it off
to the Lenneal Gardner,
02:53:05.020 --> 02:53:07.590
who's our regulatory and business manager,
02:53:07.590 --> 02:53:09.240
who's gonna talk about some
02:53:09.240 --> 02:53:12.600
of our hardening and
risk mitigation strategies.
02:53:12.600 --> 02:53:14.160
You could go to the next slide.
02:53:14.160 --> 02:53:15.510
I'll try to keep this short
02:53:16.510 --> 02:53:18.700
'cause we're running
a little bit late on time.
02:53:18.700 --> 02:53:23.330
But basically Trans Bay Cable
is an HVDC converter station
02:53:23.330 --> 02:53:26.010
which operates in the San Francisco Bay Area.
02:53:26.010 --> 02:53:26.960
Next slide, please.
02:53:28.300 --> 02:53:30.770
We have 53 miles of submarine cable
02:53:32.510 --> 02:53:34.480
and two converter stations,
02:53:34.480 --> 02:53:36.530
which are interconnected with PG&E.
02:53:38.450 --> 02:53:41.610
So both of these interconnections
02:53:41.610 --> 02:53:45.870
with the PG&E substations
are using a underground cable.
02:53:45.870 --> 02:53:48.850
So we're capable of providing 400 megawatts
02:53:48.850 --> 02:53:53.850
of real power transmission
into the City of San Francisco
02:53:53.880 --> 02:53:57.300
and each station can also
provide a significant amount
02:53:57.300 --> 02:54:01.210
of reactive power support
to support the network
02:54:01.210 --> 02:54:04.823
out in Contra Costa
County and in San Francisco.
02:54:08.490 --> 02:54:09.743
Next slide, please.
02:54:14.880 --> 02:54:18.670
Here's a picture showing our
cable route through the Bay
02:54:18.670 --> 02:54:20.330
and generally speaking,
02:54:20.330 --> 02:54:22.683
our converter stations located at each.
02:54:24.130 --> 02:54:24.963
Next slide.
02:54:30.200 --> 02:54:32.320
So our converter station in San Francisco,
02:54:32.320 --> 02:54:34.113
it's the Potrero converter station.
02:54:34.970 --> 02:54:36.480
We're primarily located
02:54:36.480 --> 02:54:41.100
in a urban city environment in the city.
02:54:41.100 --> 02:54:43.180
And you go to the next slide.
02:54:43.180 --> 02:54:45.493
We have our Pittsburgh Converter Station.
02:54:46.500 --> 02:54:48.500
Pittsburgh Converter Station is located right
02:54:48.500 --> 02:54:52.570
on the edge of the Delta,
right where the San Joaquin
02:54:52.570 --> 02:54:54.433
and Sacramento Rivers intersect.
02:54:57.113 --> 02:54:58.963
You can go to the next slide, please.
02:55:02.170 --> 02:55:04.320
So I wanna talk briefly about some
02:55:04.320 --> 02:55:09.320
of our wildfire mitigation
strategies and measures here.
02:55:09.330 --> 02:55:11.103
So next slide.
02:55:15.626 --> 02:55:19.870
So as you can see, we've
identified our proximity
02:55:19.870 --> 02:55:24.870
to the forest areas for
the wildfires in California
02:55:24.960 --> 02:55:29.960
and our Pittsburgh Converter
Station is located closer
02:55:30.970 --> 02:55:35.970
or closest to some of these fire risk zones.
02:55:36.470 --> 02:55:40.280
So approximate to the tier
two high fire threat districts.
02:55:40.280 --> 02:55:43.150
We're still not located in any Wildlands.
02:55:43.150 --> 02:55:45.653
So next slide.
02:55:48.390 --> 02:55:49.590
But we are located close
02:55:49.590 --> 02:55:51.593
to some proximate vegetative fields,
02:55:52.560 --> 02:55:55.820
the marshlands located behind us
02:55:57.362 --> 02:55:58.933
and to our West.
02:56:01.450 --> 02:56:05.360
On the next slide, we have
a more zoomed out view
02:56:05.360 --> 02:56:09.950
which shows our proximity
to those vegetative fields
02:56:09.950 --> 02:56:12.683
and then also the nearby
residential communities.
02:56:15.760 --> 02:56:16.593
Next slide.
02:56:21.180 --> 02:56:23.900
We're also taking into
consideration our location
02:56:23.900 --> 02:56:28.900
in the Bay Area in our
proximity to seismic fault lines.
02:56:29.940 --> 02:56:33.350
We're located near several faults that run
02:56:33.350 --> 02:56:36.350
through the Bay Area with
the San Andres fault being out
02:56:37.200 --> 02:56:39.320
in the San Francisco Peninsula,
02:56:39.320 --> 02:56:42.823
but the Hayward, Diablo,
and Greenville Fault.
02:56:44.620 --> 02:56:48.010
And so although unlikely,
02:56:48.010 --> 02:56:50.270
we do wanna take into consideration
02:56:50.270 --> 02:56:53.770
that seismic activity
could be a precursor event
02:56:53.770 --> 02:56:55.563
that causes an ignition.
02:56:57.770 --> 02:56:58.603
Next slide.
02:57:00.440 --> 02:57:04.620
I think here, I'll turn it over to Lenneal
02:57:04.620 --> 02:57:08.730
for our overview of our
FMLA process, which is similar
02:57:08.730 --> 02:57:11.163
to the one used by Horizons West.
02:57:12.760 --> 02:57:13.593
Thank you, Michael.
02:57:13.593 --> 02:57:16.640
And just for realizing that I'm standing
02:57:16.640 --> 02:57:20.810
between everyone and
lunch, I will skip over this slide.
02:57:20.810 --> 02:57:23.440
As Michael stated, it's
very similar to the process
02:57:23.440 --> 02:57:27.750
that Horizon West
utilizes for risk assessment
02:57:27.750 --> 02:57:31.520
of risk assessment and prioritization
02:57:31.520 --> 02:57:34.970
of the wildfire risks and
drivers in mitigation measures.
02:57:34.970 --> 02:57:37.620
So I'll skip to the next slide and discuss
02:57:37.620 --> 02:57:42.283
briefly TBCs overall wildfire
risk management overview.
02:57:45.338 --> 02:57:47.460
As Michael described earlier,
02:57:47.460 --> 02:57:50.190
TBC has a very limited footprint
02:57:50.190 --> 02:57:53.330
and as a result of the assessed wildfire risk
02:57:53.330 --> 02:57:58.330
as part of our overall
fire prevention program
02:57:58.750 --> 02:58:01.140
and operational risk reduction.
02:58:01.140 --> 02:58:03.060
And stated here,
02:58:03.060 --> 02:58:06.767
we've developed a
site-specific fire prevention plans
02:58:06.767 --> 02:58:09.060
and these plans are reviewed annually
02:58:09.060 --> 02:58:11.020
by a local fire departments.
02:58:11.020 --> 02:58:12.830
And let's move to the next slide.
02:58:12.830 --> 02:58:13.850
I'll kind of discuss some
02:58:13.850 --> 02:58:16.753
of our facility design
construction, et cetera.
02:58:18.380 --> 02:58:23.380
So just to highlight here,
TBC's cables are all underground
02:58:24.640 --> 02:58:27.123
or submerged beneath the Bay waters.
02:58:27.980 --> 02:58:31.150
All of the above ground
infrastructure is fully contained
02:58:31.150 --> 02:58:33.650
within our converter station sites.
02:58:33.650 --> 02:58:37.760
They're surrounded by 12
foot concrete walls with inward
02:58:37.760 --> 02:58:41.910
and outward facing, security
cameras inside those walls,
02:58:41.910 --> 02:58:45.580
there's a fire lanes of matter approved
02:58:45.580 --> 02:58:50.318
by the local department and Knox boxes.
02:58:50.318 --> 02:58:55.318
TBC our buildings meet
California Building Code.
02:58:55.420 --> 02:58:57.120
In addition to California building
02:58:58.160 --> 02:59:00.190
for seismic resiliency,
02:59:00.190 --> 02:59:04.980
some of the inner
infrastructure is actually designed
02:59:04.980 --> 02:59:08.640
to meet IEEE seismic resiliency,
02:59:08.640 --> 02:59:12.400
which is a higher than
the California building code.
02:59:12.400 --> 02:59:15.160
The electric system employs controls
02:59:15.160 --> 02:59:18.430
which implement protective blocking
02:59:18.430 --> 02:59:23.160
which can shut the system
down within microseconds.
02:59:23.160 --> 02:59:25.311
And so if there is a fault on the system,
02:59:25.311 --> 02:59:29.190
the system will trigger
an immediate shutdown.
02:59:29.190 --> 02:59:31.240
Below that, you see there's a list of some
02:59:31.240 --> 02:59:35.340
of the incremental hardening projects
02:59:35.340 --> 02:59:38.530
that we've undertaken upcoming years.
02:59:38.530 --> 02:59:41.500
So that's transformers, seismic pads,
02:59:41.500 --> 02:59:45.840
we're increasing the
resiliency of our transformers.
02:59:45.840 --> 02:59:48.910
We've got eight transformers at each sites.
02:59:48.910 --> 02:59:52.360
We are adding some
fire suppression capability
02:59:52.360 --> 02:59:56.710
to some of the auxiliary
buildings that we have on site
02:59:56.710 --> 03:00:00.230
in Pittsburgh, including
additional thermal barriers
03:00:00.230 --> 03:00:02.350
for auxiliary rooms.
03:00:02.350 --> 03:00:03.300
Next slide, please.
03:00:05.810 --> 03:00:06.680
Thank you.
03:00:06.680 --> 03:00:07.910
In this slide, you see a description
03:00:07.910 --> 03:00:09.760
of our maintenance practices.
03:00:09.760 --> 03:00:12.440
We conduct weekly and monthly inspections
03:00:12.440 --> 03:00:13.431
of our facilities.
03:00:13.431 --> 03:00:17.260
This includes sidewalks,
inspecting cable vaults.
03:00:17.260 --> 03:00:20.270
And we also, on the next page, I'll discuss
03:00:20.270 --> 03:00:23.260
we have real-time monitoring of our cable,
03:00:23.260 --> 03:00:28.260
which includes the ability to
monitor and pass dig notices.
03:00:29.950 --> 03:00:34.220
So we've got 24 seven
real-time monitoring of our cable
03:00:34.220 --> 03:00:39.220
and of the system through
our human machine interface.
03:00:39.420 --> 03:00:41.810
Operational practices, there's a number
03:00:41.810 --> 03:00:45.690
of our fire prevention and emergency policies
03:00:45.690 --> 03:00:49.820
or hot work fire safety
program and all operators
03:00:49.820 --> 03:00:54.820
and engineers receive training
on all of these procedures.
03:00:56.100 --> 03:00:57.050
Next slide, please.
03:01:00.890 --> 03:01:01.740
Thank you.
03:01:01.740 --> 03:01:04.960
I kind of hit earlier on
some of the situational
03:01:04.960 --> 03:01:08.520
and conditional awareness
capabilities that TBC has.
03:01:08.520 --> 03:01:11.530
And last week, just the
response and recovery,
03:01:11.530 --> 03:01:13.680
one of the things that I like to highlight,
03:01:14.720 --> 03:01:18.840
this year, we purchased
class B foam trailers,
03:01:18.840 --> 03:01:23.300
which are designed to fight
03:01:23.300 --> 03:01:26.110
and suppress transformer oil fires.
03:01:26.110 --> 03:01:27.610
So that's a capability
03:01:27.610 --> 03:01:30.077
that local fire departments did not have
03:01:30.077 --> 03:01:34.350
and so TBC purchased two trailers.
03:01:34.350 --> 03:01:38.780
There's both at our Esrello
and our Pittsburgh site.
03:01:38.780 --> 03:01:43.650
So those are on onsite for depression
03:01:43.650 --> 03:01:46.820
in case a situation arises.
03:01:46.820 --> 03:01:48.483
And other than that,
03:01:48.483 --> 03:01:52.020
I think kinda high hit all
the highlights I'd like to.
03:01:52.020 --> 03:01:55.950
So thank you much for
this opportunity to present
03:01:55.950 --> 03:01:57.880
and that's all for us.
03:01:57.880 --> 03:01:59.490
Thank you.
03:01:59.490 --> 03:02:00.723
Yes, thank you.
03:02:02.400 --> 03:02:05.420
Great, thank you so
much, Lenneal and Michael,
03:02:05.420 --> 03:02:07.640
and thank you also to all of our presenters
03:02:08.644 --> 03:02:12.680
that we've had so far
as to fit a lot of material
03:02:12.680 --> 03:02:15.503
within 10 minutes, it's understandable over.
03:02:16.920 --> 03:02:21.090
With that, we'll meet back here at 1:30 to go
03:02:21.090 --> 03:02:22.753
into the Q&A session.
03:02:23.790 --> 03:02:27.203
And apologies for eating a
little bit into your lunchtime.
