San Francisco power outage left 130,000 in the dark as self-driving cars stalled in middle of streets
San Francisco plunged into darkness when nearly 30 percent of the city was struck by a massive power outage on Saturday night.
Over 130,000 houses and businesses were left in the dark, largely in the northwest part of San Francisco, including the Richmond, Sunset, Presidio, and Golden Gate Park sections, officials said on Saturday.
As of early Sunday morning, just over 36,000 people were still without power.
The “citywide” outages forced Waymo to halt its driverless car service, stranding the autonomous vehicles in the middle of the streets, SF Gate reported.
“We have temporarily suspended our ride-hailing services given the broad power outage in San Francisco,” a Waymo spokesperson told the outlet. “We are focused on keeping our riders safe and ensuring emergency personnel have the clear access they need to do their work.”
The company shut down its operation at around 8 p.m. because the cars were unable to operate without traffic signals. Residents shared footage of the Waymo vehicles parked with their hazards flashing
At least four Waymo vehicles were parked in the middle of an intersection with their hazards on, creating a large traffic jam at the busy intersection in the North Beach neighborhood, according to video posted to X.
One passenger was left stranded inside one of the self-driving vehicles during the outage, footage obtained by the outlet showed.
A portion of the outages was blamed on a fire that broke out at a Pacific Gas and Electric substation at 8th and Mission streets in downtown San Francisco Saturday afternoon.
The outages began as early as 9:40 a.m. Pacific Gas and Electric Co. was aware of the outages and said crews were working to restore power.
Power was restored to approximately 90,000 customers just after 10 p.m. local time, Mayor Daniel Lurie announced on X.
Crews were continuing to work on the remaining 36,000 customers on early Sunday.
“For those of you that do not have power, we want you to make sure you stay safe,” Lurie said.
The 48-year-old Democrat advised residents to check on neighbors but to remember to blow out all candles they may have been using before going to bed.
“I know there’s a lot going on out there, but people really stepped up tonight and will overnight as well,” Lurie said.
Police officer presence was ramped up in the areas without power to “ensure the safety of those still on the road,” he added.
PG&E says the grid has been stabilized, and the company is not expecting any more customers to be affected.
Rail lines and traffic signals were shut down by the outage, with city officials urging residents not to travel for the remainder of the night.
City buses had their routes changed, bypassing certain stops that were affected by the outages.
“Significant transit disruptions” were reported by the San Francisco Department of Emergency Management across the city.

Thousands in one San Francisco neighborhood heading into another day without power
While many people in San Francisco have their power back, there are still thousands without it.
At a press conference Monday afternoon, Mayor Daniel Lurie said 4,000 PG&E customers in the Civic Center area are still in the dark. One of them is Parvathy Menon.
“We haven’t been able to take showers or use the bathroom,” said Menon. “Our electricity is out. I think all our food started rotting about a day in.”
She lives at 100 Van Ness. She said she’s grateful she’s going out of town tomorrow, but even that’s posing some problems.
“I actually have to pack for a trip tonight, and we’re doing it in full darkness,” Menon explained. “We are using our phone lights, we are using our laptops to charge our phones.”
Her apartment is pitch black, except for the small amount of streetlight coming through the windows. She said the apartment complex has been doing all they can to help, like providing some food and water.
They have a small generator to power some lights in the lobby and one elevator for the nearly 30-story apartment building.
Menon said she is most upset about the lack of communication from PG&E.
“Initially, when this started, we were supposed to get power back within the day, then it went to the next day and now they just stopped calling us completely,” said Menon.
San Francisco City Hall was closed for the day because of the outage, but Mayor Daniel Lurie held a press conference with Supervisors Matt Dorsey and Bilal Mahmood.
Lurie said what residents have gone through is unacceptable, and he’s lost trust in PG&E’s estimated times for repair.
“They gave us a timeline that they believe in, but it’s not one that I can have confidence in any longer,” Lurie said. “So, we don’t have full faith that 6 a.m. is the time tomorrow.”
“Shame on PG&E for having this happen,” said District 6 Supervisor Matt Dorsey. “This is a company that has had a lot of reliability issues and the jury is out on what happened, but if this is negligence, I think it’s going to be really important for people to understand they have rights as customers.”
Leaders encourage everyone who lost anything to file a claim with PG&E; they could be eligible for reimbursements. Mahmood is calling for a hearing after the new year to get some answers for PG&E.
“What went wrong, why weren’t they able to address it this weekend and what steps are they taking to make sure this doesn’t happen again,” said Mahmood about the question he has for the utility company.
PG&E said the outage happened after a fire at its Mission Street substation left significant damage, but the cause is still under investigation.
Meanwhile, Menon has been refreshing social media looking for good news, but she’s starting to lose faith.
“They’re really doing nothing to help us here, so I’m losing hope,” said Menon.

San Francisco blackout: What we know
A fire at a Pacific Gas & Electric substation in SoMa knocked out power to as many as 130,000 customers starting Saturday, leaving thousands in the dark heading into the holiday season and a week of intense storms. Here’s what we know about the outage and state of restoration.
What happened?
The fire began shortly before 1:10 p.m. Saturday at PG&E’s Mission substation at Eighth and Mission streets, initially affecting 40,000 customers. As firefighters worked to suppress the blaze, crews de-energized additional portions of the electric system for safety, causing outages to peak at approximately 130,000 customers.
The fire damaged critical equipment, including a circuit breaker — a safety switch designed to de-energize the system when problems are detected. Firefighters faced unusual complexities suppressing the fire in the multilevel building, including ventilating carbon monoxide before crews could safely enter.
When did power come back?
Firefighters made the building safe for PG&E crews to enter by 6:15 p.m. Saturday. Restoration efforts began immediately. Nearly 32,000 customers were reconnected by 8:45 p.m. Saturday, and about 100,000 — roughly 75% of those affected — were up by 9:30 p.m.
By noon Sunday, 90% of affected customers had power restored. PG&E initially projected full restoration by 2 p.m. Monday; however, a spokesperson said the utility was extending restoration times (opens in new tab) for the remaining 4,400 customers without power. No time frame has been announced.
What sparked the fire?
PG&E says it doesn’t know. COO Sumeet Singh said Monday that the extensive equipment damage makes it difficult to determine a root cause. The utility has hired Exponent, a Bay Area-based engineering firm, to conduct an independent investigation.
“We will determine what occurred to ensure it never happens again,” Singh said at a press conference outside the damaged substation.
Was the equipment properly maintained?
PG&E completed preventative maintenance at the Mission substation in October and conducted its most recent bimonthly inspection Dec. 5. Singh said neither inspection identified any problems.
Why were the estimated restoration times wrong?
Many customers were irate as they were repeatedly given estimated restoration times that came and went. Singh acknowledged the failure and said PG&E’s estimation systems typically perform well, with more than 91% accuracy systemwide.
“It obviously did not work effectively in the circumstance over this weekend,” Singh said. “We are committed to understanding exactly what happened, why it happened, and owning the fixes.”
Were other substations damaged?
Residents have observed a large presence of workers at a substation at 24th Avenue and Balboa Street since Sunday, but the utility has not shared details on what is being done there.
Six hulking diesel generators, which one worker said cost $600,000 to operate daily, were parked outside the substation Monday afternoon. The generators are needed to feed power to the grid while both substations are not fully operational. Crews said they are expected to run for at least two to three days.
Two workers said the substation is undamaged and still online, but its output is diminished because it is fed power by the much larger substation at Eighth and Mission.
However, another said one of the substation’s transformers blew out after a power surge following the fire, and the generators are needed to compensate while workers “update the system” of the west-side substation.
How will customers be compensated?
PG&E plans to offer an expedited claims process for affected customers to seek compensation for losses, including spoiled food, lost business revenue, and hotel costs. Singh said details will be available soon on the utility’s website and through customer service.
He declined to specify compensation limits or provide immediate financial relief, saying customers would need to file claims that PG&E would process quickly. The utility opened a community resource center in the Richmond and partnered with 211 to provide hotel accommodations and food vouchers for vulnerable customers.
Could this happen again?
Singh said PG&E has identified no vulnerabilities at other substations and has made significant upgrades systemwide. Two strong storms forecast for Tuesday and Wednesday (opens in new tab) could bring 4 to 10 inches of rain to Northern California; he said more than 5,500 PG&E workers and contractors are positioned to respond.
The outage occurred 22 years to the day (opens in new tab) after a mass blackout at the same substation in 2003, raising questions about aging infrastructure that Singh did not directly address.

What happened when Waymo robotaxis met a San Francisco blackout

An extraordinary experiment happened over the weekend in San Francisco.
What would a fleet of autonomous vehicles do when a widespread power outage knocked out traffic lights across one-third of the city?
We quickly found out—and the results were plastered all over social media.
On Saturday afternoon, Waymo vehicles throughout SF opted to stop where they were or pull over and throw on their hazard lights—“blocking intersections” and “compounding gridlock,” observed the San Francisco Standard—leading the Alphabet-owned robotaxi operator to suspend service throughout the city. (It resumed Sunday evening.)
In a statement, Waymo said that its vehicles are “designed to treat non-functional signals as four-way stops” but “the sheer scale of the outage led to instances where vehicles remained stationary longer than usual.”
As locals worked through the outage, a moderate debate about the robotaxi fleet continued online. Was it so wrong to expect Waymo’s vehicles to play it safe when infrastructure stopped working? After all, aren’t human drivers predictably chaotic when things go sideways? What exactly should robotaxis optimize for: traffic flow or citizen safety?
And: Just how safe is stopping if you prompt traffic to go around you?
Waymo resumed service Sunday evening, no doubt grappling with these questions (and what city officials might have to say about them). “We are already learning and improving from this event,” it said. —AN
