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.
