Power outage in Petaluma blacks out 4,900 customers

PG&E crews were looking for the cause of a large power outage early Monday in Petaluma.|

A large power outage centered in east Petaluma early Monday knocked out electricity to 4,900 customers, according to PG&E.

Power company troubleshooters looking for the cause found two spots in the system that had failed. The problems, which occurred at almost the same time, involved an overhead wire on South Ely Boulevard west of Casa Grande Road and an underground line along Rainier Avenue, said Deanna Contreras, utility company spokeswoman. But what led to the equipment issues remained under investigation.

“Some customers heard loud noises and reported seeing some explosions,” Contreras said.

The initial 5:24 am. outage involved 3,500 customers. In fixing and assessing that issue, crews briefly pulled the plug on about 1,400 more customers.

The initial outage was fixed by 7:15 a.m. and 11 customers still without power late Monday morning were due to be restored by 11:30 a.m.
