Seoul, Korea - May 30, 2013 -LG Chem, Ltd. has been selected by Southern California Edison (SCE) to deliver a 32 MWh battery energy storage system (BESS) for SCE's Tehachapi Wind Energy Storage Project (TSP), a project funded by the DOE using ARRA funds. With 32 MWh of energy, the BESS is the largest battery energy storage system in North America. The batteries that LG Chem will be installing into the BESS are capable of providing electricity to about 100 homes for one month and are equivalent to the number of lithium-ion batteries used in approximately 2,000 Chevrolet Volt electric vehicles manufactured by General Motors.


The objective of the project is to evaluate the capability of utility scale lithium-ion battery technology to improve grid performance and assist in the integration of variable energy resources into the SCE grid. The 32 MWh lithium-ion battery BESS for the TSP project will be connected to SCE's Antelope-Bailey 66 kV system and will reside inside a 6,300 square foot facility at SCE's Monolith substation in Tehachapi, California.
"Viable energy storage solutions will allow for a smarter grid and assist in the integration of intermittent renewable resources", said Mark Irwin, director of Technology Development at Southern California Edison. "This project will demonstrate the performance of the lithium-ion batteries in actual grid level system conditions and the capability to automate the operations of the BESS and integrate its use into the utility grid."

"This project is one of the big milestones built upon the synergies of LG Chem's advanced battery technologies and experiences throughout its mobile, automotive and energy storage battery business", said Dr. Seokhwan Kwak, vice president of the Energy Solution Company at LG Chem. "Collaborating closely with Southern California Edison on this project will provide key performance data and real-world experience and this will be a stepping stone of LG Chem BESS business to strengthen its position as a leader of battery manufacturers."
