PG&E Blames 'Catastrophic Incident' For Outage as Over 10,000 Remain Without Power, Muni Still Disrupted

"The Great San Francisco Blackout of December 2025 continues into its third day for some residents, and Muni subway service remains disrupted due to ongoing impacts from the PG&E outage. As of Monday morning, December 22, the power outage that began on December 20 has persisted for around 11,600 PG&E customers in San Francisco, primarily concentrated in the Outer Richmond and around the Civic Center area. PG&E has pledged full restoration of power to these areas by 2 pm Monday."

"Several blocks on either side of Market Street between 8th Street and Van Ness remain in the dark, likely due to ongoing repairs at the PG&E substation at 8th and Mission where a fire reportedly occurred on Saturday afternoon. And as a result, San Francisco City Hall remains closed this morning, as KTVU reports, as does the Main Branch of the SF Public Library."

"Muni subway service remains out, with no underground trains operating between Embarcadero and Castro stations. There is normal service on the K, L, and M lines to the west of Castro, with trains switching back and bus shuttles taking anyone downtown who's still going to to the office or to work downtown this week. As happened on Sunday, the J-Church and N-Judah lines are being interlined (combined) for surface-only service between Balboa Park and Judah/La Playa."

A widespread PG&E outage beginning December 20 left about 11,600 San Francisco customers without power, concentrated in the Outer Richmond and Civic Center. Restoration was pledged by PG&E by 2 pm Monday, while repairs continued at the 8th and Mission substation after a reported Saturday fire. Several blocks around Market Street remained dark, prompting closure of San Francisco City Hall and the Main Branch of the SF Public Library. Muni subway service was suspended between Embarcadero and Castro; K, L, and M lines operated west of Castro with trains switching back and bus shuttles downtown. J-Church and N-Judah ran surface-only, interlined, with transfers to bus shuttles required at Church and Market. PG&E provided an incomplete explanation, and a similar 2003 outage was also linked to a fire at the same substation.
