SAN FRANCISCO, December 22, 2025: A major power outage struck San Francisco on Saturday, cutting electricity to more than 130,000 homes and businesses across several neighborhoods, according to Pacific Gas and Electric Company (PG&E). The blackout disrupted transportation networks, shuttered businesses, and darkened large sections of the city as utility crews worked to restore power throughout the day. The outage began shortly after midday and affected large portions of the city’s northern and central districts. Areas including North Beach, the Marina, Pacific Heights, and Russian Hill experienced widespread loss of power.
The disruption left traffic signals nonfunctional and forced many stores, restaurants, and public facilities to close. PG&E said field technicians were deployed immediately to locate and repair the affected transmission lines, but did not specify the initial cause of the failure. San Francisco’s Department of Emergency Management confirmed extensive service disruptions across the city. The agency advised residents to avoid unnecessary travel, warning that transit systems were experiencing significant delays. Traffic signals across several intersections went dark, prompting authorities to remind motorists to treat intersections as four-way stops.
Emergency responders were positioned in critical areas to help direct vehicles and maintain safety on major routes. The outage coincided with the final weekend before Christmas, a peak period for retail and dining activity in the city. Local businesses in affected areas reported abrupt shutdowns as lighting, refrigeration, and point-of-sale systems failed. Public spaces, including shopping corridors along Union Street and Chestnut Street, were largely deserted after power loss forced early closures. Many residents turned to portable devices and flashlights as neighborhoods remained dark into the evening.
Thousands of residents left without power across San Francisco
City officials confirmed that backup generators were activated at key facilities, including hospitals, emergency communications centers, and public safety departments. The San Francisco Municipal Transportation Agency reported that several bus and light rail lines were delayed or temporarily suspended because of power-related signal failures. Crews were dispatched to inspect overhead wires and verify electrical integrity before resuming full service.
PG&E said its operations teams were working “as quickly and safely as possible” to restore electricity. The company’s outage map indicated that service was gradually returning by late evening, with most customers back online before midnight. Smaller clusters of outages persisted in select areas while crews completed equipment testing and final repairs. Authorities said full restoration was expected within hours of the initial event.
Officials urge residents to stay prepared for future interruptions
The utility company, which provides energy to millions of customers across Northern and Central California, has faced repeated infrastructure challenges in recent years due to aging equipment and weather-related strain on transmission systems. Saturday’s event prompted renewed logistical coordination between PG&E and municipal agencies to ensure the stability of essential services. The company stated it would conduct a technical review to determine the precise cause of the system failure once restoration efforts were complete.
Public safety officials said there were no immediate reports of injuries or fires related to the outage. Emergency dispatch centers handled increased call volumes during the blackout, primarily for stalled elevators, malfunctioning alarms, and reports of darkened intersections. The city’s emergency management department maintained communications through its backup systems and issued continuous updates via social media and public radio.
PG&E investigating cause of large-scale city power failure
As of Sunday morning, power was fully restored to all affected areas, PG&E confirmed. The company said its engineers were monitoring grid stability to prevent recurrence and assessing whether recent weather fluctuations or equipment faults contributed to the disruption. City operations returned to normal, with public transportation services running on schedule and traffic systems fully reactivated.
The incident marked one of the most extensive single-day outages in San Francisco in recent years, underscoring the city’s reliance on resilient energy infrastructure amid seasonal demand surges. Authorities encouraged residents to maintain preparedness for potential power interruptions and to follow safety guidelines during any future emergencies. – By Content Syndication Services.
