People observe an area affected by a blackout that hit about 130,000 residents, according to the Pacific Gas and Electric Company, in San Francisco, Calif.

Power was ‌restored for about 110,000 customers in San Francisco after a sizable part of the city was hit by an ‍outage on Saturday, according to the city’s emergency management department and its main utility firm, Pacific Gas and Electric ​Company. The blackout affected about 130,000 ​residents in the California city of around 800,000 people, PG&E said.

“Crews restored about 110,000 customers by 7:30 a.m. ‍Sunday and are working to restore the ​power for around 21,000 who remain ⁠without electric service,” the utility said, adding that there were no injuries to workers or members ⁠of the public.

The outage caused traffic jams and forced some businesses to close temporarily. “A large power outage is impacting San Francisco – only call 9-1-1 for life safety emergencies, avoid non-essential travel, treat down ⁠traffic signals as four-way stops, keep ‍refrigerator and freezer doors closed, and turn off major appliances to prevent surges,” the San Francisco ‍Department of Emergency Management said in ​a post on social ‍media earlier on Sunday.

Separately, Tesla CEO Elon Musk said on Sunday the company’s robotaxis were unaffected by the outage.
