MOSS LANDING — Hundreds of people were ordered to evacuate and part of Highway 1 in Northern California was closed early Friday after a major fire erupted at one of the world’s largest battery storage plants.

The fire started Thursday afternoon and sent up towering flames and black smoke, and about 1,500 people were instructed to leave Moss Landing and the Elkhorn Slough area, The Mercury News reported.

Fire Contained but Still Burning

The blaze was still burning early Friday with some containment and it had not gone beyond the facility, according to Monterey County spokesperson Nicholas Pasculli. As of late Thursday, a few dozen people were at a temporary evacuation center and the rest had gone to friends or family or made other arrangements, Pasculli said.

The Moss Landing Power Plant, located about 77 miles south of San Francisco, is owned by Texas-based company Vistra Energy and contains tens of thousands of lithium batteries. The batteries are important for storing electricity from such renewable energy sources as solar energy, but if they go up in flames the blazes can be extremely difficult to put out.

“There’s no way to sugar coat it. This is a disaster, is what it is,” Monterey County Supervisor Glenn Church told KSBW-TV. But he said he did not expect the fire to spread beyond the concrete building it was enclosed in.

Emergency Response and Investigation

The county Board of Supervisors planned an emergency meeting Friday morning to receive a briefing on the fire.

There were fires at the Vistra plant in 2021 and 2022 that were caused by a fire sprinkler system malfunction that resulted in some units overheating, according to The Mercury News.

It was unclear what caused this latest fire. Vistra said in a statement that after it was detected, everyone at the site was evacuated safely. After the fire is out, an investigation will begin.

“Our top priority is the safety of the community and our personnel, and Vistra deeply appreciates the continued assistance of our local emergency responders,” Jenny Lyon, a spokesperson for Vistra, said in a statement.
