(AP) - Two warming centers were established east of San Francisco after a gas line lost pressure and left roughly 6,200 utility customers without gas.
In response, crews replaced some equipment at a station that regulates gas pressure.
Service has been restored to about 2,800 customers.
PG&E spokeswoman Mayra Tostado says that the utility had problems with its gas distribution system in Discovery Bay, and now officials are trying to determine the extent the cold weather played in the loss of gas pressure.
Warming centers were set up at Timber Point Elementary School and at the Discovery Bay Community Center. Meals and a warm place to rest will be available.
With the outage, the utility warns that all representatives from PG&E have identification and people should ask for it if they are unsure the representative is legitimate.
