An outage in Long Beach Thursday afternoon affected 2,735 customers, according to Southern California Edison. Services were restored to customers within an hour according to Lauren Bartlett, spokeswoman for SoCal Edison.
Firefighters found smoke coming from an underground vault north of downtown Long Beach shortly before 3 p.m. on Thursday, the associated Press reports. However, officials say there were no flames and no explosion.
There were two major power outages in Long Beach last month caused by vault fires. The second took out power for 30,000 customers, some for up to two days, while the earlier one affected 6,300 homes and businesses and took three days to repair. Bartlett said that Thursday's outage is unrelated.
"This outage is not on the same system as the two previous outages in Long Beach," she said.
The Thursday outage is under investigation. SoCal Edison crews will be on site at the origin point of the outage as long as they deem necessary, Bartlett said.
