San Francisco – A major San Francisco power outage brought California’s iconic city to a near standstill on Saturday, plunging large sections into darkness for several hours and creating widespread chaos during one of the busiest holiday shopping weekends of the year. The blackout affected approximately 130,000 homes and businesses across the city of over 800,000 residents, disrupting daily life, commerce, and transportation throughout multiple neighborhoods.
Substation Fire Identified as Primary Cause
According to Pacific Gas and Electric Company, the San Francisco power outage originated from a fire at a PG&E substation located near the intersection of 8th and Mission streets. City officials confirmed that this substation fire triggered the blackout shortly after 1 pm on Saturday, causing extensive damage to critical infrastructure. The fire led to cascading power failures that rippled across multiple neighborhoods, leaving vast portions of the city without electricity during peak afternoon hours.
PG&E officials characterized the damage from the substation incident as “significant and extensive,” indicating that repairs would be complex and time-consuming. The utility company emphasized that the scale of destruction at the facility would require substantial restoration efforts involving specialized equipment and personnel to bring the San Francisco power outage to a complete resolution.
Gradual Restoration Efforts Underway
By early Sunday morning, restoration crews had made considerable progress in addressing the San Francisco power outage, successfully restoring electricity to approximately 110,000 customers. However, roughly 21,000 customers remained without power as utility workers continued their round-the-clock efforts to repair damaged infrastructure and restore full service to all affected areas.
Pacific Gas and Electric mobilized additional engineers and electricians to expedite the restoration process following the San Francisco power outage. Despite these enhanced efforts, the utility company could not provide a precise timeline for complete power restoration to all customers, citing the complexity of repairs needed at the damaged substation facility and throughout the affected distribution network.
Transportation Systems Severely Impacted
The San Francisco power outage created immediate and severe disruptions to the city’s transportation infrastructure. Traffic lights went dark across wide areas of the city, forcing police officers to manually direct traffic at busy intersections throughout the affected zones. The city’s Department of Emergency Management issued urgent advisories urging residents to avoid non-essential travel and treat non-functioning traffic signals as four-way stops to prevent accidents.
Public transportation services faced significant challenges during the San Francisco power outage. Trains on portions of the city’s rapid transit network were compelled to bypass certain downtown stations, while bus services experienced substantial delays due to gridlocked roads and non-functioning traffic control systems. As an additional safety precaution, self-driving ride-hailing services operated by Waymo were temporarily suspended throughout the affected areas, further limiting transportation options for residents and visitors.
Economic Impact on Holiday Shopping Season
The timing of the San Francisco power outage significantly amplified its economic consequences. With Christmas just days away, the blackout struck during a critical period for retailers and restaurants that traditionally experience high customer volumes during the final holiday shopping weekend. Many commercial establishments were forced to close for the day, leaving normally bustling commercial districts eerily quiet and deserted.
Business owners described the sudden drop in foot traffic as “devastating” to their holiday sales projections. The San Francisco power outage coincided with fog blanketing parts of the city, creating a double deterrent that further discouraged shoppers from venturing out. Retailers who had prepared extensively for one of the year’s most profitable shopping periods found themselves unable to serve customers or process transactions during peak hours.
City Officials Coordinate Emergency Response
Mayor Daniel Lurie addressed the situation from the emergency operations center, acknowledging the significant strain the San Francisco power outage placed on residents and businesses alike. He characterized it as a “rough day” for the city while emphasizing that authorities were maintaining close coordination with Pacific Gas and Electric and first responders to manage the crisis and restore normalcy as expeditiously as possible.
Emergency management teams worked throughout the day to address safety concerns arising from the San Francisco power outage, including traffic management, public safety coordination, and communication with affected residents and businesses about restoration timelines and safety protocols.

Grid Stabilization and Ongoing Investigation
By Saturday evening, Pacific Gas and Electric announced that crews had successfully stabilized the electrical grid and did not anticipate further outages related to the substation incident. This stabilization represented a critical milestone in managing the San Francisco power outage and preventing additional cascading failures that could have extended the blackout’s duration and geographic scope.
Investigations into the precise cause of the substation fire that triggered the San Francisco power outage remain ongoing, with officials working to determine whether equipment failure, external factors, or other circumstances contributed to the incident. Authorities reported no injuries linked to the fire or the resulting blackout, though the full economic impact continues to be assessed as the city works toward complete power restoration and normal operations.
