Wildfire Mitigation Plan December 2, 2019
California’s Wildfire Risk Year-Round Fire Season: Changes to California’s climate means that the traditional notion of a fire “season” no longer exists Hazardous fuel is building up: 10M acres of land contain ready-to-burn kindling from nearly 147M trees that have been killed or weakened by drought and bark beetle infestation Source: http://www.fire.ca.gov/communications/downloads/fact_sheets/Top20_Destruction.pdf 1
Local Community High Fire Risk Area Map Approximately 1/3 of SCE’s 50,000 square mile service area is located in HFRA. What makes up SCE’s HFRA? A combination of historical map boundaries (based on past fire management and response experiences), CAL FIRE’s Fire Hazard Severity Zone (FHSZ) maps, and most recently the CPUC High Fire Threat District map are used to inform CPUC Tier 3 = ~18% SCE’s High Fire Risk CPUC Tier 2 = ~9% Areas. Other HFRA = ~8% * Areas within SCE’s service area that continue to be designated as HFRA and are in the process of being evaluated to determine whether they remain as HFRA 2
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 • OPERATIONAL Public Safety Power Effective communications and engagement with emergency services, customers and • Shutoff (PSPS) communities Situational Awareness Weather stations and HD cameras • 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 INFRASTRUCTURE Circuit miles of covered conductor in HFRA • Undergrounding Evaluation of certain distribution lines in HFRA for potential undergrounding. • Various system hardening activities (e.g., composite poles, current limiting fuses (CLFs), • Other Infrastructure remote automatic reclosers (RARs), Fast Curve settings) Mitigations Studies, evaluations and pilots of alternative technologies • 1 Per SCE’s Grid Safety & Resiliency Program (GSRP) 3
Infrastructure - System Hardening Elements Hardened System Covered Conductor Reclosers Fast-Acting, Current Limiting Fuses (CLF) 4
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 HFRA 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 5
Situational Awareness Capabilities Fire Advanced Monitoring Weather Cameras Weather Modeling Stations Hi-Res Data Better Forecasting High-Definition • • • Local Weather Advanced Warning Remote-controlled • • • Situational Awareness Center SCE meteorologists • 24/7 monitoring • 6
Public Safety Power Shutoff (PSPS) ▪ De-energization to prevent ignitions from powerlines ▪ Used during extreme fire conditions ▪ Primarily impacts circuits in high fire risk areas ▪ Other circuits in non-high fire risk areas may be impacted if transmission lines are de-energized ▪ Red Flag Warning does not mean a PSPS will be called ▪ Actual frequency of PSPS events will depend on various weather and environmental factors ▪ Decision will be made with most accurate assessment of real- time information and situational awareness data 7
PSPS Decision Points Decision points include but are not limited to: SCE Meteorologists Real-time Impact of • • • forecast strong observations de-energizing wind conditions in from qualified circuits on first service territory personnel responders and monitoring for essential services SCE Fire Scientist hazardous • assessment of fire conditions in potential to include the field consideration of weather and fuels * Erratic or sudden onset of conditions may prevent the input from real-time observations or consultation with first responders 8

What is Load Shifting? WITHOUT LOAD SHIFTING Typical Solar Situation: (Net Energy Metering) You export solar to the grid when you don’t need it and get a monetary credit for each kWh that is sent to the grid. WITH LOAD SHIFTING You will charge your battery with your solar system during the day and then use some of that energy in the evening instead of buying the most expensive energy from the grid Graphic from Energy Storage News
