San Francisco power: What has been affected?

By Saturday afternoon, traffic stalled on a dark San Francisco street as street lights went out or went into the emergency blinking mode.

The San Francisco Department of Emergency Management said that traffic lights in areas where power is out may be impacted. “If a traffic signal has gone dark, always treat it as a four-way stop.”

The power outage also dampened the Christmas spirit, as the holiday decorations went dark.

Restaurants reportedly put out candles for diners to keep the place running.

The San Francisco Bay Area Rapid Transit District (BART) said the Powell Street and the Civic Center stations were also closed because of the outage.

In an X post, BART said that there is a 10-minute delay on the San Francisco Line in all directions due to a power outage at Powell and Civic Center stations.

What caused the massive San Francisco power outage?

According to the news outlet, citing San Francisco Fire Lt Mariano Elias, a fire broke out inside a PG&E substation at 8th and Mission streets at about 2:15 PM, which caused at least some of the blackouts.

Employees reported smoke inside the building, and firefighters were using specialised carbon monoxide equipment to extinguish the flames on the first floor of the four-story building, Elias said.

PG&E's first public response

In their first public response to the outages, PG&E, in an X post, said, “We are working with first responders and city officials on an outage in #SanFrancisco affecting 130,000 customers. We will share more information as it becomes available.”

It remained unclear what prompted the initial blackouts in the Inner Sunset, Richmond and other West Side neighbourhoods.

Emergency ops center opens

San Francisco opened its emergency operations center to coordinate the city’s response.

Mayor Daniel Lurie posted a video from inside the center urging people “to be safe out on the roads.”

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