Tesla’s Elkhorn Battery Storage Facility, located in Monterey County, CA, caught fire Sept. 20 around 1:30 a.m., after one Tesla Megapack was reported ablaze.

PG&E told Teslarati it became aware of the fire at 1:30 a.m., and as of 9:28 a.m., that fire was still being fought by local firefighters with assistance from PG&E.


The fire seemed to have started in an isolated Megapack, according to details released by PG&E. The fire was confined to a single Megapack, Tesla’s commercial battery storage system. The safety systems at the facility worked as designed when the fire was detected. The battery storage facility was automatically disconnected from the electrical grid, the company told Teslarati.


There have been no injuries to onsite personnel, and customers had reported no outages as of 9:28 a.m. Reports indicated Highway 1 had been closed due to the fire. PG&E did not include this in their statement.


The 182.5-megawatt energy storage system was commissioned and certified for market participation by the California Independent System Operator on April 7. The battery helps store excess energy from solar panels and helps California avoid blackouts during heat waves and other times when energy use is high.


Two hundred fifty-six Tesla Megapacks are present on the site, with the ability to store and dispatch up to 730 megawatt-hours of energy to the grid at a maximum rate of 182.5 MW for up to four hours during times of high demand. Construction on the project began in July 2020.
