A major power outage left 50,000 people in Northern California unplugged on Sunday morning.
Large slopes of Albany, Berkeley, El Serrito, Kensington, Oakland, Richmond and San Pablo have been affected, said JD Guidi, a spokesman for Pacific Gas and Electric Company.
The power loss began at 7:35 am. After equipment damage in El Cerrito, Mr. Guidi said.
Three hours after the power outage, said Mr. Guidi, the company restored power to 10,000 customers, but there was no forecast yet as to when the power would be fully restored.
"Much of Berkeley is out of power this morning," Berkeley City tweeted Sunday morning, directing residents to follow the development and follow advice on how to prepare.
The Express Transit Center in downtown Berkeley Bay was closed due to a power outage, an agency reported in a tweet . The agency later stated that had activated a backup generator to provide power to the station.
Passengers were advised to expect delays.
Jenny Wong, elected Berkeley's city auditor, said she noticed the power was out at about 8am and went for a walk with her husband to see how the South Berkeley neighborhood was moving. Ms Wong said she noticed that the traffic lights were down and many businesses were open but unlit.
"It was very calm," she said. "I just felt really bad for the people working in the small market we passed. Employees stood outside because they could not do business when that happened. “
