More than 6,100 miles of covered conductor installed since 2018 Installing mix of composite poles and wooden poles with fire-resistant wrap to reduce risk of damaged poles during an emergency FIRE-RESISTANT POLES COVERED CONDUCTOR PROTECTIVE DEVICES Installing fast-acting fuses and using faster grid protection settings to interrupt electric current more quickly when there’s an electrical fault and remote-controlled sectionalizing devices to segment and isolate portions of circuits during PSPS events. Undergrounding in targeted high fire risk areas based on risk criteria and feasibility, nearly eliminating wildfire and PSPS risks associated with electric facilities. About 29 miles of undergrounding completed since 2021. Data as of 9/30/2024 HARDENING ELECTRIC GRID & INFRASTRUCTURE TARGETED UNDERGROUNDING RAPID EARTH FAULT CURRENT LIMITER (REFCL) Deploying REFCL technology more widely. REFCL detects when a single power line has fallen to the ground and almost instantly reduces energy released. 7 •6,100+ miles of covered conductor, covering about 64% of SCE’s overhead distribution lines in high fire risk area •Covered conductor estimated to be about 70% effective •Upgraded ~117 miles of covered conductor within Moorpark COVERED CONDUCTOR Data as of 12/31/2024 8 •Completed ~29 miles of undergrounding in targeted high fire risk areas based on risk criteria and feasibility since 2021 •Including 0.61 mile within Moorpark •Nearly eliminates wildfire and PSPS risks associated with electric facilities •Ramping up scope in the coming years •About 7,300 miles, or about 43% of primary distribution lines in high fire risk areas, already underground TARGETED UNDERGROUNDING 9 COVERED CONDUCTOR AND TARGETED UNDERGROUNDING ARE EFFECTIVE MEASURES TO REDUCE WILDFIRE & PSPS RISKS Covered conductor is a very valuable tool to expeditiously and cost-effectively reduce wildfire risk specific to SCE Undergrounding pursued for certain locations based on risk profile Execution Speed Unique FactorsCost to Implement ~2.9 ~4.5+ ~0.7 Under- ground Covered Conductor Undergrounding is considered where there is: •Communities of elevated concerns •High burn frequency •Limited egress •Wind speeds exceeding covered conductor PSPS thresholds •Exceptionally high potential consequence (>10,000 acres) •Operational feasibility Cost per mile1 $ in Millions ~75-85%lower Geography Chaparral (brushland) presents different primary risk factors than heavily forested areas Vegetation Type Evergreen Forest Deciduous Forest Broadleaved Forest Chaparral Grassland Desert Scrub Covered Conductor Under- ground Initiate ~2–3 ~2–3 Plan ~6–9 ~9–15 Schedule ~6–9 ~9–15 Execute ~2–3 ~5–15 Total 16–24+25–48+ Avg.
