Los Angeles Department of Water and Power (LADWP) has selected Doosan GridTech and its partner, KTY Engineering, to deliver LADWP’s first battery energy storage system (BESS) with a capacity of 20 MW at its Beacon Solar Plant in Kern County, California.

The Beacon Solar Plant was selected as the site for the BESS due to the its high concentration of solar photovoltaic arrays. The BESS will provide multiple, coordinated functions to LADWP that will help efficiently integrate these solar resources into the grid, minimize LADWP’s use of gas‐fired generating units for compliance with the NERC – BAL 003-1 requirements, and assist with the short-term mitigation of the Aliso Canyon natural gas curtailment.

Doosan’s winning modular turnkey design includes thirteen transformer/PCS/lithium-ion battery strings, redundant auxiliary power systems, and 100% redundant HVAC systems. The design also enables preventative maintenance, which is necessary in the harsh Mojave Desert environment, to occur without sacrificing availability.
