A large-scale power outage plunged approximately 130,000 homes and businesses in San Francisco into darkness Saturday, affecting roughly one-third of Pacific Gas and Electric Co.’s customers in the city.
The blackout began in the early afternoon, initially hitting the Richmond and Presidio neighborhoods and areas surrounding Golden Gate Park before spreading to a substantial portion of the city’s northern section. The widespread outage caused significant disruption across California’s financial and technological hub.
Fire officials reported that at least some of the power failures stemmed from a fire inside a PG&E substation located at 8th and Mission streets, according to a statement posted on social media around 3:15 p.m. The utility company has not yet provided comprehensive details regarding the cause of the massive outage.
The timing of the blackout proved particularly challenging for local businesses during the holiday shopping season. Social media platforms quickly filled with reports of restaurants and retail shops forced to close their doors, while street lights and festive Christmas decorations throughout the affected neighborhoods went dark.
“We’ve stabilized the power grid and are not expecting additional customer outages,” PG&E announced on X (formerly Twitter) at approximately 4 p.m. However, the utility company was unable to confirm whether power would be fully restored by Saturday evening, leaving thousands of residents uncertain about when normal service would resume.
The San Francisco Department of Emergency Management issued a citywide alert, warning of “significant transit disruptions” and advising residents to avoid non-essential travel. The department also reminded motorists to treat non-functioning traffic signals as four-way stops to prevent accidents and maintain order on the roads.
Public transportation systems were significantly impacted by the outage. The San Francisco Municipal Transportation Agency (Muni) and Bay Area Rapid Transit (BART) both reported service interruptions, with several stations bypassed due to the lack of power. These disruptions further complicated mobility for residents and visitors throughout the city.
Power outages of this magnitude are relatively rare in San Francisco but highlight the vulnerability of urban infrastructure. The city’s densely populated neighborhoods and concentration of businesses make widespread blackouts particularly disruptive to daily life and economic activity.
PG&E, Northern California’s largest utility provider, has faced increasing scrutiny in recent years over infrastructure reliability and safety concerns. The company has been implementing system upgrades following criticism related to previous outages and its role in several devastating wildfires across the state.
Saturday’s blackout comes at a time when California’s aging power grid faces mounting challenges from extreme weather events, increasing demand, and the transition to renewable energy sources. Utility companies across the state have been working to modernize infrastructure while balancing costs and reliability.
For affected residents, the outage meant adjusting weekend plans and dealing with practical concerns such as food spoilage, heating issues, and communication limitations. Many businesses faced lost revenue during what would typically be a busy pre-holiday weekend.
City officials continue to monitor the situation closely, with emergency services remaining on high alert. Updates regarding restoration timelines and affected areas are being provided through official channels and social media platforms as crews work to address the underlying causes of the outage and restore power to all customers.

A fire in a PG&E substation seems like a concerning issue that requires prompt investigation. Power reliability is crucial, especially in a major city like San Francisco. Hopefully PG&E can provide more details soon and get the grid back up and running without further delays.
You make a good point. Electrical infrastructure failures can have far-reaching impacts on a city. Timely communication from PG&E will be important to reassure the public and coordinate emergency response.
Losing power during the busy holiday shopping season must be incredibly frustrating for San Francisco residents and businesses. I hope PG&E can get to the bottom of this issue quickly and restore service. Reliable electricity is essential for a thriving urban economy.
You’re absolutely right. Outages like this can have cascading effects on local commerce and community life. PG&E will need to prioritize a swift and thorough response to mitigate further disruptions.

Concerning to hear about the widespread power outage in San Francisco. This must be causing major disruptions for businesses and residents during the busy holiday season. I hope PG&E can quickly identify and address the root cause to restore power safely and efficiently.
This is a significant blackout that will impact many businesses and households. With the holidays approaching, the timing could not be worse. I wonder if this outage is related to PG&E’s aging grid infrastructure that has been problematic in the past.
This sounds like a major disruption for the city of San Francisco.
