LG Energy supplies batteries to world's largest ESS project

Korean battery maker LG Energy Solution said Thursday it has completed the supply of its battery system to the world's largest energy storage system (ESS) that has come online in the United States.

LG Energy, a battery unit under LG Chem, said its lithium-ion batteries are now running on U.S. power generation firm Vistra Energy's 1.2 gigawatt-hour (GWh) ESS facility in California.

In December, Vistra connected the ESS facility to its 1,020-MW combined cycle gas turbine power plant site in Monterey County, California.

The battery storage system is used to absorb excess power generated by renewable resources, mainly solar, and to put it onto the grid in peak times.

LG Energy said the world's largest ESS project used over 4,500 stacked battery racks, each containing 22 individual battery modules, which were pre-assembled at its factory prior to shipment to reduce construction time and associated installation costs.

The Korean company said it expects to win additional ESS contracts in the world's biggest market as demand is expected to further grow under the Joe Biden administration's eco-friendly policies.
