A large, unplanned power outage knocked out electricity to Bayview and Visitacion Valley Tuesday morning, leaving roughly 2,694 PG&E customers in the dark across San Francisco's southeastern neighborhoods. The disruption, first flagged in a social media alert, is the latest entry in a year of recurring blackouts that have tested residents' patience and the city's aging electrical infrastructure.
The outage was first flagged in an alert from the San Francisco Department of Emergency Management, which was reposted by SFMTA
. The alert noted that a large, unplanned power outage was impacting PG&E customers in Bayview and Visitacion Valley. According to the same post, PG&E offers real-time outage maps, updates, and estimated restoration times through its outage center, and customers can sign up directly with the utility for outage alerts. That information is also available in English, Spanish, Chinese, and Tagalog, and affected customers can call 1-800-743-5002 for current outage details.
Tuesday's blackout wasn't an isolated event. According to Cedar News, an initial verified figure put the number of affected customers at roughly 2,694, while crews worked to restore service. Elsewhere in the city, a separate outage hit Cathedral Hill and nearby neighborhoods, with PG&E attributing that blackout to low oil levels in a transformer, as reported by The Cool Down. Combined with disruptions in Sausalito, more than 5,000 customers across the region lost power Tuesday during a late-season heatwave, the outlet reported, a reminder that hot weather places added stress on aging distribution equipment.
A City Already on Edge Over Blackouts
The Bayview and Visitacion Valley outage arrived just days after another major disruption rattled downtown San Francisco. On October 1, an unplanned PG&E blackout cut power to 3,182 customers in the Tenderloin and Western Addition, hours after an underground electrical fire ignited four PG&E vaults in the Financial District, according to KTVU. Hoodline covered that blackout in detail in its piece on the vault fire aftermath downtown.
That wasn't an anomaly either. Hoodline previously reported on a 455-customer outage along the Embarcadero that knocked out traffic signals during evening rush hour near the Ferry Building, as well as a large blackout affecting western San Francisco's Richmond and Sunset districts in late September. In late August, a Bernal Heights blackout marked what Hoodline described as the city's seventh major outage of the year, underscoring just how often San Francisco neighborhoods have gone dark in 2026.
When outages disable traffic signals at intersections, they can disrupt traffic along major corridors — as happened during the Embarcadero outage near the Ferry Building.
Scrutiny Mounts Over PG&E's Grid Maintenance
The pattern of outages has fed into broader questions about PG&E's handling of its aging San Francisco infrastructure. An independent investigation by engineering firm Exponent, released in May, found that PG&E knew about damaged equipment at its Mission Substation before a December 20, 2025 fire cut power to 120,000 San Francisco customers, according to the SF Standard. That investigation attributed the fire to high humidity and condensation buildup at the substation.
CleanPowerSF serves more than 385,000 residential and commercial customers across the city, while PG&E controls the physical distribution lines delivering that power.
Public Power Push Gains Momentum
The recurring blackouts come as San Francisco edges closer to a potential takeover of PG&E's local grid. On September 22, the Board of Supervisors unanimously affirmed the final Environmental Impact Report for the city's proposed acquisition of PG&E's electric distribution infrastructure, a key legal step toward public power expansion, per the SFPUC. The move reflects years of mounting frustration with the utility's reliability record in San Francisco.
A proposal associated with Supervisor Shamann Walton called for a 45-day pause on citywide approvals for data centers, as Hoodline reported in its story on the proposed data-center pause. District 10 has long hosted a heavy concentration of industrial infrastructure, adding another layer to the neighborhood's relationship with the power grid.
What Affected Residents Should Know
For households riding out Tuesday's outage, keeping refrigerator and freezer doors closed can help preserve cold air for as long as possible.
