A large, unplanned power outage swept through Bernal Heights and adjacent San Francisco neighborhoods overnight, cutting electricity to PG&E customers before crews restored service. The San Francisco Department of Emergency Management confirmed the outage was resolved after alerting residents to the blackout in the early hours.
The San Francisco Department of Emergency Management, which posted the update just before 1 AM, said the outage had impacted PG&E customers in Bernal Heights and adjacent areas. Residents in the area, bounded roughly by streets including Cortland Avenue, Precita Park, Bernal Heights Park and the Alemany Boulevard corridor, were urged to check PG&E's Outage Center or call 1-800-743-5002 for real-time updates, with information also available in English, Spanish, Chinese and Tagalog. PG&E also offers direct outage alerts to subscribers, and outage maps, updates and estimated restoration times can be found at pgealerts.alerts.pge.com.
Update: the outage is resolved.

The San Francisco Department of Emergency Management, based in the city, also reminded residents that they can sign up for localized alerts through its AlertSF system by texting their ZIP code to 888-777. The department separately oversees the city's 911 dispatch center, which processes more than 1.4 million calls annually.
Part of a Persistent Pattern Across the City
The Bernal Heights blackout is only the latest in a string of San Francisco outages this year. Just a day earlier, Haight-Ashbury and the Western Addition went dark in what Hoodline described as the city's sixth big outage this year. That followed an August 19 pole fire that knocked out power to 5,000 Outer Sunset homes, and an August 13 blackout that darkened traffic lights across the city's west side, according to Hoodline's earlier reporting. Russian Hill, North Beach and Chinatown experienced their own major blackout on August 10, while Outer Richmond and Sea Cliff were hit by a sudden outage back in March.
Motorists navigating any of these blackouts face specific legal obligations when traffic signals go dark. Under California Vehicle Code Section 21800(d)(1), drivers approaching an intersection with inoperative signals must come to a complete stop and proceed with caution, treating the intersection as an all-way stop and yielding to vehicles on their immediate right, according to FindLaw.
A History Stretching Back Years in Bernal Heights
Bernal Heights has faced electrical infrastructure trouble before. In September 2015, a PG&E transformer explosion outside a residence on Coleridge Street injured two people while utility crews were working five blocks away repairing a downed wire from a separate outage, CBS News reported at the time. A third-party investigation was launched to determine whether the downed line contributed to that blast.
More recently, a July 18 incident showed how even routine grid work can trigger blackouts. A protective safety device unexpectedly activated during scheduled switching between two San Francisco substations, leaving nearly 9,400 PG&E customers without power across the Richmond, Presidio, Sea Cliff and Golden Gate Park neighborhoods. PG&E said the switching work was intended to allow maintenance without de-energizing large areas, per reporting on the incident.
December's Mission Substation Fire Still Looms Large
The frequency of 2026's outages has kept scrutiny on PG&E's grid maintenance practices, especially after a December 20, 2025 fire at the utility's Mission substation cut power to roughly 130,000 San Francisco customers during peak holiday shopping season. A third-party investigation report by engineering firm Exponent, released in May, found that PG&E had been aware of equipment damage and moisture issues at that substation a month before the fire, according to the SF Standard. Following that blackout, PG&E issued automatic bill credits of $200 for residential customers and $2,500 for businesses, and had received more than 2,700 additional customer claims by late January, with the utility reporting that 86% of submitted claims were resolved in less than 15 days.
San Francisco's Push to Take Over the Grid
The repeated outages have added fuel to San Francisco's long-running effort to acquire PG&E's local distribution system and run it as a municipal utility. The San Francisco Public Utilities Commission already generates and supplies about 75% of the electricity consumed in the city through Hetch Hetchy Power and CleanPowerSF, but PG&E retains monopoly ownership of the physical grid that delivers that power to customers, according to SFGATE. San Francisco has submitted multiple acquisition offers to PG&E since 2019.
On July 9, the San Francisco Planning Commission unanimously certified the final Environmental Impact Report for the city's proposed acquisition of those distribution assets, a major procedural step toward establishing a municipal electric utility under the SFPUC. City officials estimate the local electrical distribution network is worth roughly $3.4 billion. The move follows Senate Bill 875, legislation introduced in February by State Senator Scott Wiener and San Francisco officials designed to ease legal and regulatory hurdles for cities trying to purchase electric infrastructure from investor-owned utilities, a push that came after a series of winter blackouts left some San Francisco residents without power for up to three days, according to KQED.
