Gateway Energy Storage Explained

Gateway Energy Storage is a large-scale battery storage power station, operated by grid infrastructure developer LS Power. It has 250 MW of power and a storage capacity of 250 MWh (1 hour), using lithium-ion battery cells from LG Chem.^{[1] [2] [3]}

The purpose of the battery is to provide power during times of peak demand after being charged partly with solar power during the day.

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.

In May 2024, the battery suffered 3 fires over 5 days.^[4]
