A smoking Pacific Gas and Electric Co. manhole in SoMa was related to an outage affecting about 3,300 customers Thursday, the San Francisco Fire Department said in a tweet. PG&E said only about 17 customers were still without power as of about 3 p.m., and they would get electricity back when repairs were completed.

The Fire Department said shortly after announcing the incident that it had resolved it without any injuries or people being displaced. A spokesperson could not be reached for further comment.

The public was advised to avoid the area at 1300 Bryant St. near the intersection with Division Street close to the Highway 101 overpass.

PG&E spokesperson Mayra Tostado said in an email that the company was notified at about 12:25 p.m. of an outage affecting 3,345 San Francisco customers. Crews were dispatched and found an underground equipment failure.

Tostado said the company was working with first responders to make sure the area was safe and had attempted to connect customers experiencing outages to other parts of the power system.

“We apologize for the inconvenience and thank our customers for their patience and understanding while we work to safely restore power as quickly as possible,” Tostado said.

The company’s online outage map showed a patchwork of blocks without power in SoMa between Seventh and 11th streets and running from Market to Brannan streets earlier in the afternoon.

An area on and around Market Street was also experiencing outages between Van Ness Avenue and Octavia Street, the map showed.

District Six Supervisor Matt Dorsey tweeted confirmation of the outage.

A video on the app Citizen from Thursday afternoon showed two PG&E trucks and a van parked in front of 1300 Bryant near a large manhole with the cover off. No smoke or flames were visible coming from the manhole.
