Newsom's proposals to hold utilities accountable for mitigating wildfire threats. Creates a wildfire fund that will help victims and affected communities recover and rebuild more quickly. Establishes objective standards to help determine if a utility acted prudently to manage wildfire threats to ensure safety and resiliency. Provides more reasonable direction on cost allocation for utilities. Energy for What's Ahead" 4 Scope of SCE's 2019 SB 901 Wildfire Mitigation Plan • Enhanced overhead inspections (EOI) on transmission and distribution structures in HFRA Inspections . Various existing inspections (poles, switches, circuits, relays, etc.) • Infrared, Corona scanning and high definition (HD) imagery J Q Z Public Safety Power • Effective communications and engagement with emergency services, customers and O Shutoff (PSPS) communities Situational Awareness • Weather stations and HD cameras a O • Hazard tree removal (trees beyond traditional trim zone) • Vegetation removal at poles Vegetation Management • LiDAR surveying for transmission, supplemental inspections in HFRA • SCE plans to implement a 12 -ft tree clearances from distribution power lines in high fire areas to ensure annual growth will not encroach on compliance distances. "' Covered Conductor • Circuit miles of covered conductor in HFRA Undergrounding • Evaluation of certain distribution lines in HFRA for potential undergrounding. Ln Other Infrastructure • Various system hardening activities (e.g., composite poles, current limiting fuses (CLFs), remote automatic reclosers (RARs), Fast Curve settings) LL Z Mitigations Studies, evaluations and pilots of alternative technologies Per SCE's Grid Safety & Resiliency Program (GSRP) Energy for What's Ahead' 1 5 Objective of SCE's Wildfire Mitigation Plan 1. Protect public safety 2. Implement the plan to reduce the risk of potential wildfire -causing ignitions associated with SCE's electrical infrastructure 3. Implement measures that further harden SCE's electric system against wildfires and improve system resiliency 4. Enhance wildfire suppression efforts by improving fire agencies' ability to detect and respond to emerging fires in coordination with utility emergency management personnel 5. Effectively communicate with customers, community groups, and other stakeholders about how to prevent, prepare for, and mitigate the effects of wildfires Energy for What's Ahead" 6 Infrastructure - System Hardening Elements Hardened System Fast -Acting, Current Lim'*;�� Fuses (CLF) .. gi ELF Current Limiting Fuse Covered Conductor Reclosers Energy for What's Ahead' 17 Enhanced Overhead Inspections (EOI) Enhanced Overhead Inspections Identify Potential Risks • In less than 5 months, our crews completed detailed ground- based inspections of 400,000+ distribution and transmission structures in HFRA • Deploying helicopters and drones equipped with Infrared, Ultraviolet, LiDAR and HD image scanning to perform aerial inspections of our facilities in H F RA SCE's helicopters are equipped with software and high-tech cameras, like the one shown above, to find potential risk undetectable to the human eye Energy for What's Ahead' 8 Situational Awareness Capabilities • Hi -Res Data Better Forecasting • High -Definition • Local Weather Advanced Warning • Remote-controlled Situational Awareness • SCE meteorologists • 24/7 monitoring Energy for What's Ahead" 9 Wildfire HD Camera www.alertwildfire.org Energy for What's Ahead' 10 Weather Stations 1-h&Menu -'-Search.
