Update 2:30 p.m.: (AP) - A utility company spokesman says the San Francisco power outage that left thousands in the dark was caused by a "catastrophic failure" of a circuit breaker that caused a fire at a power substation.
Pacific Gas & Electric spokesman Barry Anderson says power has been restored to about 23,000 of the 90,000 customers that previously lost power in a massive swath of the central city.
He says soot from the debris of the fire swept across the area and took out more customers.
In a statement posted on its website, PG&E says it expects to restore power to about 25,000 more customers "in the next few hours" and to remaining customers late in the afternoon.
Update 12:00 p.m.: PG&E says power has been restored to 10,000 customers in San Francisco.
San Francisco Police Department says on Twitter it understands the concerns regarding the coincidence of outages in other cities. But, Nicole Liebelt with PG&E says the San Francisco power outage is apparently due to an equipment failure at a substation.
San Francisco Fire says it received multiple calls about people stuck in 20 elevators in the city. The department says it has responded to over 100 calls since 9:30 a.m. There have been no injuries related to the incident, according to San Francisco Fire Department.
PG&E estimates power to be restored by 1 p.m.

According to AP, an MTA generator restored signal power around 11:30 a.m. Friday in New York City.
Cond Edison says one of its electrical lines triggered the outage, according to AP. Spokesman Allan Drury says it's not clear how long the repairs will take or how the failure occured.
Kevin Ortiz with MTA says some passengers were stranded on trains and some cars were dark except for phone lights.
Original: About 90,000 customers have been affected by a power outage in San Francisco, according to Pacific Gas & Electric.
The outage includes the Financial District and other areas. According to Bay Area Rapid Transit, the downtown Montgomery Station has been shut down due to the outage.
A series of outages began affecting parts of the city at 9 a.m. Friday, says PG&E spokeswoman Tamar Sarkissian. She also says crews are assessing the situation but there's no immediate estimate for when power will be restored.
Another power outage in New York City caused major subway delays Friday morning. The Metropolitan Transportation Authority says the power went out around 7:30 a.m. Friday at 53rd Street and Seventh Avenue in Manhattan, according to the Associated Press.
AP also says, the MTA cited "a Con Edison power issue." But utility spokesman Bob McGee said the cause hadn't been pinpointed and Con Edison isn't the only power source there.
