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.

Latest California-based gig work app lets people book content creators, editors

Latest California-based gig work app lets people book content creators, editors


It’s 10 a.m. sharp, and Abby Kurtz gets her first assignment of the day. She’s received a time, a location in San Francisco and a target.

Her weapon of choice: an iPhone.

“Being a social agent is really the coolest thing ever,” she said. 

Kurtz is a content creator working through an app called Social Agent, part of an expanding gig economy where more and more workers are trading stability for flexibility. Work that once required connections, planning, and a big budget can now be booked with a tap —extending the on-demand model from rides and meals to storytelling itself.

 Just make a request, and someone like Kurtz can arrive within 30 minutes, camera-ready.

“What I look for when I’m shooting events is very crisp and clean content,” she said. 

Her mission this time took her to Sutro Nursery, a nonprofit dedicated to growing native plants and that is hoping to grow its volunteer base, too. Board member Maryann Rainey said booking a Social Agent is a lot cheaper than hiring someone to do their social media full-time. 

“I know I can’t do it myself, and I was certainly hoping that these young people would know how to do a good film,” Rainey said.

A typical job runs about $200, with same-day delivery. Agents earn around $50 an hour, plus tips. And if clients already have footage, they can upload it and have it turned into a finished piece.

The service is currently available in New York, Los Angeles, and Miami, with a slower rollout now underway in other cities.

 Lisa Jammal, the company’s CEO, said the idea is simple: Let someone else do the shooting.

“We all are missing those beautiful moments because we’re always behind the phone,” she said. 

As for Kurtz, after the shoot, she headed straight to a nearby coffee shop, where the clock started ticking. She had just over an hour to shape her raw material into a polished final cut.

“I think I’m going to give this reel a really peaceful, calming feel, but also informative and inviting,” she said.

SF scientists build robotic storm samplers to track pollutants before they reach the Bay

SF scientists build robotic storm samplers to track pollutants before they reach the Bay


SAN FRANCISCO (KGO) — Environmental Scientist Kayli Paterson from the San Francisco Estuary Institute is hitting the road with colleague David Peterson and a trunk full of water sampling robots.

“Yeah, I think the max we’ve ever done was five. But the sites are very close together. Oh, there it is. Hopefully it samples well,” says Paterson as she turns the mobile sampling lab onto a private oak-lined road.

They’re closing in on a watershed creek flowing through the hillsides near the San Andreas Lake reservoir, west of Highway 280 in Millbrae, part of the larger watershed that eventually drains into San Francisco Bay.

“So, we’ve got our sampler. Look at the battery. Hook that up, red and black. This is a 12-volt lithium battery, and it powers our sampler for probably about six to seven days,” she explains, showing off a self-contained unit miniaturized into a portable case.

The black cases are their latest innovation in stormwater science. Robotic samplers anchor in key sections of the watershed to monitor not only flow, but also the chemicals and pollutants washing downstream toward the Bay.

“And this is a front-line pollution sampler. It’s getting the stormwater before it enters the Bay. And so, we want to know what’s coming into the Bay and getting these samplers out there in more locations will give us a better idea of where we might have issues, where a hotspot is, or maybe a previously unknown contaminant,” says Paterson.

“It’s important to get out that fast,” her colleague David Peterson adds. “You know, in these storms as they’re happening, because the water is picking up pollutants in real time, and we need to be there to capture them.”

When we first met Peterson several years ago, he and another Estuary Institute team were sampling water along the Bay shoreline by hand, a technique that’s still valuable. But to cover more ground, Kayli and a group of collaborators began developing the robotic samplers over recent storm seasons.

Kayli and David start by chaining the unit itself to a tree near the creek bank. The system employs remote-controlled pumps that draw samples from the creek and store them in onboard containers. The software controlling the volume and frequency can be operated from a phone app.

One of the key targets in this study is a group of so-called “forever chemicals” known as PFAS, synthetic compounds that persist in the environment and have been detected in widespread areas of the Bay.

“And we capture samples and send them off to analytics labs across the country. Typically, universities or private labs will process these for us,” Peterson explains.

For these two stormwater detectives, it’s a mission that requires a combination of speed and patience**, chasing flowing water** through creeks and storm drains, sampling as they go.

“So, we’re looking for areas – the point of this is to do source control. Ultimately, we want to be able to trace this back to a possible source,” says Kayli Paterson.

And potentially prevent a source of toxic pollution from reaching San Francisco Bay and our Bay Area ecosystem.

More than a dozen of the robots were given names in a special contest, including the Big Sipper and the Tubeinator.

Floats for San Francisco Chinese New Year Parade get finishing touches


SAN FRANCISCO (KGO) — ABC7 Eyewitness News got a sneak peak as crews put the finishing touches on the floats you’ll see at Saturday’s San Francisco Chinese New Year Festival and Parade.

Since it’s the year of the fire horse, you’ll see a lot of horses and fire symbolism on the floats, housed at Pier 19.

“So Year of the Horse, it’s energy, it’s passion, it’s momentum so a lot of things that we’re really hoping to embody in the new year,” said Stephanie Mufson, owner of San Francisco-based The Parade Guys, which designs and constructs the floats.

She said they’ve been building them for about three months, with the designs starting in November.

“We’re in the home stretch,” she said. “We’ve got a couple of days left and we’ve got a nice little team that’s cranking out all the finishing work that needs to go into it.”

Derrick Shavers was sanding some wood that will be painted and become cherry blossom trees on a float.

“It’s exciting,” Shavers said. “I look forward to coming every year and just creating and making things shine and sparkle.”

Bon was painting mountains for a float, making sure everything is perfect in time for the parade.

“It’s one of the few parades that actually happens at night still,” Bon said. “So we got to make sure all the lighting is in check, and people are safe on the float. It’s all in the details, just for it to walk by you for 10 seconds.”

Ten seconds that bring so much joy to those watching the parade.

Here’s how you can watch the parade on ABC7 Eyewitness News on Saturday, March 7.

Coverage starts at 5 p.m. wherever you stream ABC7.
