SAN FRANCISCO – A widespread power outage affected thousands of PG&E customers across the city on Saturday, with the latest figures showing 39,520 customers still dark. The outage was first reported in the Inner Sunset around 9:40 a.m. and initially impacted about 14,700 customers.
By 10:10 a.m., the outage had expanded to roughly 25,000 customers across the Richmond District, the Presidio, golden Gate Park, the Inner Sunset, and areas near the Civic Center, according to PG&E’s updates.
Crews were evaluating the fault as of about 2 p.m., with the utility estimating that most customers would have power restored by 3:45 p.m. and the remaining customers by 7:15 p.m., per the outage map.
City officials advised residents to treat non-emergency power-outage reports as non-urgent and to keep 911 lines open only for life-safety emergencies. Traffic signals in affected zones could be out and should be treated as four-way stops.
rain is forecast for Saturday night, with wind gusts up to 25 mph. Wet conditions are expected to continue into the coming days, possibly complicating restoration efforts.

Rapid checklist for affected households
- Check circuit breakers – Reset any tripped breakers before contacting PG&E.
- Preserve food safety – Move unopened refrigerated items to a cooler with ice packs.
- Use battery‑powered devices wisely – Prioritize phones for emergency calls.
- Report hazards – Notify the city if you spot downed power lines or gas leaks.
BART Service Disruptions
- Stations closed: Embarcadero, Montgomery, Civic Center, and 12th St. Oakland City Center (served by the Transbay Tube).
- Alternative transport:
- Muni Bus routes 30, 38, 45 were deployed as “shuttle buses” between affected stations.
- Ride‑share partners offered 15 % discount codes through the BART app.
- Ridership impact: An estimated 85 % drop in peak‑hour boardings between 00:00-06:00 PT.
PG&E Response & Restoration Strategy
- Deployments: 6 line crews, 2 substation specialists, and a mobile transformer unit.
- Tools used:
- Infrared thermography to locate hot spots on the feeder.
- Remote‑controlled switches for rapid isolation of damaged sections.
- Restoration phases:
- Stabilization – secure the faulted line and reroute power through alternate paths.
- Re‑energization – Gradually re‑close breakers while monitoring voltage stability.
