. . . r PRACTICE OF LAST RESORT: PUBLIC SAFETY POWER SHUTOFF • De-energization to prevent wildfire ignitions l Used only in most extreme weather conditions Limited to impacted circuits in high fire risk areas • More frequent use possible given increased wildfire risk Frequency and duration driven by weather Notifications starting 48 hours before potential power shutoff ' , / • • 1st Responders, Local Governments, Water/ Communications Providers, an.d Customers (especially critical care & medical baseline) • Decision to ·de-energize considers variety of factors SCE will be in regular contact with fire/emergency personnel prior to " decision • Power restoration begins after local conditions have improved and safety r checks have been performed Energy for What's Ahead» I 44

PUBLIC SAFETY POWER SHUTOFF -CONSIDERATIONS· Many factors inform decision to turn power off. Factors include but are not limited to: • Real-time conditions • Weather station data • Trained field personnel in local area • Input from fire authorities and Emergency Management Personnel • Evacuation orders I status • Impact on essential services • Location of evacuation centers • Other emergency operations· • Energy for What's Ahead"' + 46

· PSPS EVENT FREQUENCY AND DURATION FORECAST 2-10 PSPS shutoffs per year predicted (system wide) Outages predicted to last between half a day to a few days • Predictions based on historical weather data and past PSPS events. Actual frequency and duration depends on a number of factors which cannot be forecasted with certainty • Event frequency and duration predictions across all of SCE's high fire risk areas • Scope/impact of extreme fire conditions and time to conduct safety checks of our equipment following these conditions will affect the duration of these outages.
