It has 250 MW of power and a storage capacity of 250 MWh (1 hour), using lithium-ion battery cells from LG Chem.

[3] It is located next to the Pio Pico and Otay Mesa (1 GW combined) natural gas-fired power stations in Otay Mesa, California, on the outskirts of San Diego, at the Mexican border.

The fire was centered in one of seven buildings at the 250-megawatt site, which houses several lithium-ion batteries designed to support California's power grid.

Evacuation orders and warnings were put in place in the immediate vicinity of the facility, an area that includes several businesses.
