Power outages San Francisco leaves 130,000 customers in total darkness Saturday, what fire at PG&E Mission substation reveals about the city’s infrastructure

Power outages San Francisco left 130,000 customers without electricity Saturday afternoon as a fire erupted inside a PG&E substation in the Mission District. The massive blackout plunged roughly 30% of the city into darkness, triggering complete chaos at traffic intersections with non-functioning signals and transit disruptions across BART and Muni during peak holiday season.

Massive Scale of San Francisco Outage Saturday

Nearly 130,000 homes and businesses went dark across San Francisco as multiple outages rippled through the city starting early morning. The first outage struck around 9:40 a.m. affecting the Inner Sunset down to Forest Hill, taking out just over 14,600 customers. A second major outage began around 10:10 a.m. across the Presidio, Richmond, and Market Street sections with over 24,800 customers impacted.

By mid-afternoon, the blackouts had spread dramatically south into the Outer Sunset and east across the city, with the situation growing progressively worse throughout the day. PG&E provided little public information for hours beyond their online outage map, leaving residents and businesses scrambling to understand the scale of the crisis.

Fire at PG&E Substation Triggers Crisis at Mission District

A single-alarm fire at the PG&E substation located at 8th and Mission Streets played a major role in the catastrophic outages. San Francisco Fire Department Lieutenant Mariano Elias confirmed the blaze broke out at approximately 2:15 p.m. on the first floor of the four-story building.

PG&E employees called 911 at 2:16 p.m. to report smoke inside the structure. Firefighters deployed specialized carbon monoxide equipment to extinguish the flames. PG&E employees evacuated and shut off power to the building to allow firefighters to safely douse the blaze. By 6:00 p.m., the fire department had fully extinguished the fire, and company investigators began examining the scene to determine the cause.

Traffic Lights Out, Transit Chaos Ensues

Impact Area	Service Status
Street Lights	Dark or blinking emergency mode
Traffic Intersections	Non-functioning signals, traffic jams
BART Stations	Powell and Civic Center bypassed
Muni Service	Van Ness station bypass announced at 1:40 p.m.
Citywide Impact	30% of San Francisco customers without power

Street lights across vast swaths of San Francisco went completely dark or were reduced to blinking emergency mode. Traffic jams formed almost immediately at every intersection with non-functioning signals, creating dangerous driving conditions throughout the city. BART trains began bypassing Powell and Civic Center stations due to complete loss of power.

San Francisco Municipal Transportation Agency (SFMTA) announced at 1:40 p.m. that Muni trains would bypass Van Ness station. By 3:00 p.m., both transit agencies had confirmed additional station bypasses, creating gridlock for commuters and holiday travelers.

City Businesses, Museums, Libraries Forced to Close

Businesses across San Francisco faced devastating closures at the height of holiday shopping season. Multiple restaurants, bars, and retail establishments shut down immediately when power vanished, leaving owners to turn away customers and send staff home without a day’s wages.

The California Academy of Sciences, Randall Museum, and all city library branches sent patrons home. Iconic establishments like Julie’s Pizza, Miller & Lux at Chase Center, and the famous 500 Club bar in the Mission District all went dark. Holiday decorations that had brightened storefronts and homes vanished instantly, creating an eerie atmosphere across normally bustling commercial corridors.

Restaurant workers improvised by putting out candles for diners still trying to eat. Bar owners lamented losing a profitable day of sales, especially with two major football games scheduled. Small business managers like Josh Johnson at Bazaar Cafe had to immediately close and ask customers to leave, unable to run espresso machines or keep refrigerated items cold.

Will Power Restoration Happen Quickly, and What’s Next for PG&E?

As of late Saturday evening, PG&E provided no timeline for when power would be restored to any part of the city. The company posted its first public update to social media at 4:00 p.m., stating they were “working with first responders and city officials on an outage in #SanFrancisco affecting 130,000 customers,” promising more information as it became available. Automated phone calls to residents stated there was no estimated restoration time.

Mayor Daniel Lurie opened San Francisco’s emergency operations center by mid-afternoon to coordinate the city’s response. He urged residents “to be safe out on the roads” in a video posted from inside the center, emphasizing that city officials would continue communicating with PG&E throughout the night.

“A lot of the lights are out. Stay safe and we will continue to be in touch with PG&E.”
