Massive Project Tests Battery Energy Storage
Southern California Edison is opening the largest battery energy storage project in North America – the Tehachapi Energy Storage Project.
The demonstration project costs about $50 million with matching funds from SCE and the Department of Energy as part of the American Recovery and Reinvestment Act of 2009.
The 32 MWh battery energy storage system features lithium-ion batteries housed inside a 6,300-sq-foot facility at SCE’s Monolith substation in Tehachapi, Calif. The project is strategically located in the Tehachapi Wind Resource Area that is projected to generate up to 4,500 MW of wind energy by 2016.
The installation will allow SCE to evaluate the technological capabilities of energy storage on the electric grid.
Over a two-year period, the project will demonstrate the performance of the lithium-ion batteries in actual system conditions and the capability to automate the operations of the battery energy storage system and integrate its use into the utility grid.
The battery system supplied by LG Chem is comprised of 604 battery racks, 10,872 battery modules and 608,832 individual battery cells – the same lithium-ion cells installed in battery packs for General Motors’ Chevrolet Volt.
