Power was finally restored to all customers in the San Fernando Valley Thursday night after a day-long outage that affected some 15,000 homes and businesses.

The incident began about 8:45 a.m. when a crow came into contact with a 34,500-volt circuit breaker at a distributing station in Valley Village, the Los Angeles Department of Water and Power said in a statement.

About 15,000 customers in the Valley Village area lost power, the utility said.

By 4:30 p.m., service was restored to about 2,500 and about 13,000 remained without electricity, DWP said. It wasn’t immediately clear why the figures totaled 15,500. Outage information

Crews were working to resolve the outage, and the effort was expected to continue into nighttime, the utility said. The majority of customers were expected to get power back Thursday night.

By 7:30 p.m., 11,000 customers impacted by the outage had their power back.

The utility tweeted at 10 p.m. that power had been completely restored.

In a tweet published shortly after 10:30 a.m, in response to a customer’s inquiry, the utility said power was estimated to be restored within 10 hours, adding that “we often beat the estimates.”
