About 11,600 PG&E customers in San Francisco remained without power as of 11 p.m. Sunday, according to the utility.
The customers affected are mainly located in the Presidio, the Richmond District, Golden Gate Park and small areas of Downtown San Francisco, the utility said.
About 130,000 customers lost power Saturday afternoon after a fire broke out at a PG&E substation in the SoMa District, causing “significant damage,” according to the utility company.
“The damage from the fire in our substation was significant and extensive and the repairs and safe restoration will be complex,” said a PG&E spokesperson on Sunday night. “We currently expect to restore all remaining customers impacted by the substation outage no later than 2 p.m. Monday.”
The large outage means that several city offices and other public buildings will be closed Monday, the Sheriff’s Office said.
City Hall, the Main Library, the Civic Center Garage, Muni customer service on Van Ness Avenue, and offices at 525 Golden Gate, 101 Grove St., and 1 Van Ness Ave. will be closed Monday.
The War Memorial’s Veterans Building and the Asian Art Museum will also not be open to the public without restoration of power, the Sheriff’s Office said.
PG&E opened a resource center in the Richmond District, one of the areas still without power Sunday, at 251 18th Avenue, that will be open from 5 p.m. to 11:59 p.m. It will offer snacks, drinks, Wi-Fi, and charging stations. It will reopen on Monday at 8 a.m., the utility said.
PG&E said it would provide food assistance and hotel vouchers for customers left vulnerable by the outage through the Disability Disaster Access & Resources program offered by the California Foundation for Independent Living Centers, a nonprofit advocacy organization that PG&E sponsors.
On Sunday, San Francisco Supervisor Alan Wong called for a hearing into what he said were frequent power outages in his district. He also said he wants answers for why an outage that began in a localized area of the city eventually spread to one-third of San Francisco.
“It’s important that we fully understand what happened,” said Wong in a statement from his office. “We still don’t have a clear explanation for how a localized incident escalated into an outage affecting so many neighborhoods. This hearing is about getting answers, improving communication, and making sure residents and small businesses are better supported going forward.”
PG&E also activated its Emergency Operations Center in Vacaville to respond to the San Francisco outage and the ongoing storm. The utility said crews were pre-positioned Sunday in anticipation of rain that was forecast to continue through Friday.
