Largest battery energy storage in North America now operational

LG Chem’s 32-MWh battery energy storage system, built for Southern California Edison (SCE), has reached operation in Tehachapi, CA. The installation makes this storage system the largest in North America.

In May 2013, SCE chose LG Chem to deliver the storage system for the Tehachapi Energy Storage Project (TSP), funded by SCE and the Department of Energy (DOE) as part of the American Recovery and Reinvestment Act (ARRA).

“The Tehachapi Energy Storage Project is a significant milestone for SCE and for energy storage in California,” said Doug Kim, director of Advanced Technology at Southern California Edison. “Grid-scale energy storage is an integral part of our company’s Storage Portfolio Development Framework that will contribute to optimizing grid performance and integrating more renewable energy resources. This demonstration project will give us a significant amount of insight into the operational capabilities of large-scale lithium-ion battery storage.”

LG Chem lead the construction, engineering and design alongside ABB, Inc. and LG CNS Corp. SCE will test the system’s capabilities for transmission, grid, and market applications under thirteen specific operational uses.
