EIR-0392Provisional entry. Confirmed by a single newspaper report that a PG&E transformer fire in San Francisco's Richmond District caused an unplanned outage affecting over 11,000 customers; the precise technical cause of the equipment failure has not been independently verified or further detailed by PG&E. No further update is scheduled; the entry stays provisional until new information is published.
A transformer fire in the Richmond District of San Francisco caused an unplanned power outage affecting more than 11,000 Pacific Gas and Electric Co. (PG&E) customers on Sunday night. The fire was reported around 7:45 p.m. near 12th Avenue and Balboa Street. Fire officials said firefighters secured the scene until PG&E crews arrived. PG&E attributed the outage to an overhead equipment failure but did not provide further detail. The outage affected customers and some traffic signals in the Richmond District, Golden Gate Park and the Presidio until around 11 p.m. The incident occurred as PG&E was preparing to restore grid power to about 6,000 customers in the same area who had relied on temporary generators since the prior week, following a larger outage that began 20 December and affected 130,000 customers citywide at its peak.
PG&E stated the outage was caused by an overhead equipment failure, without providing further detail. The utility did not confirm whether the failure was connected to the planned switch back to grid power that occurred later the same night.
- Overhead transformer equipment can fail and ignite even during routine grid restoration efforts, requiring coordinated response between fire services and utility crews.
- Transitioning customers from temporary backup power sources back to grid power should include heightened monitoring for equipment issues during the changeover period.
- Clear public communication about the specific cause of equipment failures helps maintain customer trust, particularly following extended prior outages.
