Decision 12-04-024 provided for afterthefact Commission reasonableness review of SDG&E’s deenergization decisions, required community notice and mitigation measures, and mandated reporting to the Commission on deenergization events. We explained the stark new reality of wildfire events in California in Resolution ESRB8: The 2017 California wildfire season was the most destructive wildfire season on record, and saw multiple wildfires burning across California, including five of the 20 most destructive wildlandurban interface fires in the state's history. Devastating fires raged in Santa Rosa, Los Angeles, and Ventura, and the Thomas Fire proved to be the largest wildfire in California history. These fires further demonstrated the fire risk in California. As a result of the fires and critical fire weather conditions, both the President of the United States and the Governor of California issued State of Emergency declarations. Resolution ESRB8 at 2. The Commission’s Safety and Enforcement Division (SED) reviewed SDG&E’s deenergization events that occurred in December 2017. SED reached the following conclusions: SDG&E faced a real and significant risk of wildfires and its deenergization decisions were based on an adequate risk assessment. Prior to deciding to deenergize specific circuits, SDG&E considered and implemented other mitigation strategies, including adjustments of recloser settings, vegetation management, and inspection and monitoring during the extreme fire risk conditions. SDG&E considered locationspecific wind speeds and the age, condition, and loading of facilities on the circuits and reasonably believed that there was an imminent and significant fire hazard. SDG&E made reasonable efforts to mitigate the adverse impacts on customers and communities in areas where SDG&E deenergized circuits.
