Blackout in San Francisco
Circuit breaker failure causes major power outage.
SAN FRANCISCO: A San Francisco power outage that stranded people in elevators and left tens of thousands of others in the dark was caused by the massive failure of a circuit breaker that sparked a fire at a power substation, a utility company spokesman said.
Power had been restored to nearly all of the 90,000 customers who lost power in the financial district and other areas of the city, Pacific Gas & Electric spokesman Barry Anderson said.
About 3,000 customers remained without power late Friday afternoon, the utility said.
The Fire Department tweeted that it had responded to more than 100 calls for service, including 20 stuck elevators with people inside.
At hospitals, surgeries were disrupted briefly, but no problems were reported because backup generators kicked in, Mayor Ed Lee said.
“The best news of all was no injuries were associated with this incident,” Fire Chief Joanne HayesWhite said.
No traffic collisions were reported, either, and officials thanked motorists for driving so cautiously during the blackout. In fact, people in the city of 850,000 people were generally courteous to each another.
The city’s iconic cable cars were taken out of service as a precaution since street lights were not operating on large parts of their routes.
Tourists were not griping, though, said spokeswoman Erica Kato.
“Everyone’s very understanding – it’s not us,” she said.
The outage initially closed the Bay Area Rapid Transit agency’s downtown Montgomery Station.
People used the lights of their cellphones to walk through the darkened station before service was restored.
Later, people milled on sidewalks, controllers directed traffic manually, and shops were dark.
Some buildings had power, oth- ers did not. ATM screens were blank and the city’s famed cable cars were shut down for hours.
People were confused about what was going on and what to do, said Pam Martinez, a 25-year-old San Francisco resident and software engineer who was on a train when she heard the announcement that her destination station was closed.
“Even crossing the street was chaotic because the street lights don’t work and there’s a few ambulances trying to go through.”
Patricio Herrera sat glumly in his darkened restaurant at what should have been a busy lunch hour full of people hungry for his freshly ground hamburgers.
“We have lost everything today.” Anderson said the substation that failed was set to be part of a US$100mil (RM440mil) upgrade of the power system.
