ORANGE COUNTY, Calif. (KABC) — A massive power outage left tens of thousands of people without electricity Thursday night across South Orange County and parts of San Diego County.

San Diego Gas & Electric reported that more than 100,000 customers were initially affected. Video taken near the Civic Center in Mission Viejo showed one of the areas impacted by the blackout. Other areas that were impacted included Laguna Hills and Laguna Niguel.

The cause of the outage was not immediately known. Just after 9 p.m., San Diego Gas & Electric issued an alert announcing that power had been restored to all customers.

“We understand how disruptive outages can be and are working to investigate the cause,” said SDG&E in a statement. “The safety of our customers, employees and communities remains our top priority.”

The utility did not release additional details about what led to the widespread disruption.
