A fire at the world’s largest battery storage plant in Northern California smoldered Friday after sending plumes of toxic smoke into the atmosphere, leading to the evacuation of up to 1,500 people. The blaze also shook up the young battery storage industry.

People living near a power plant in Central California were ordered to evacuate their homes Thursday night after a fire broke out at the facility, officials said.

Then in September 2022, a fire broke out at the PG&E Elkhorn battery plant. Police closed Highway 1 for 12 hours. An investigation found it was caused by an improperly installed vent shield on one of the 256 units, which allowed rainwater to get in and short out the batteries. There were no injuries to firefighters, PG&E employees or the public.
