Southern California Edison (SCE) has selected Powin Energy to build a 2MW/8MWh energy storage system to provide critical grid support and capacity services.

The selection resulted from a process started in response to the California Public Utilities Commission's (CPUC) Aliso Canyon Energy Storage (ACES) request for energy storage projects that could be operational by the beginning of 2017. Powin's project will be powered by over 8 MWh of LFP Li-ion battery cells and controlled by their patented Battery Pack Operating System (bp-OS). It is being installed at Powin Energy's 5,000 square-foot facility in the Irvine Business District. The business district location was specifically chosen to help mitigate the threat of electricity service interruptions to that critical load area.

Powin Energy's project will be able to provide 2.0 MW of power for over four continuous hours, thus providing a reliable and continuous source of energy to serve peak demandevents. In addition, the project will supply regulation and flexible capacity support as needed and depending upon the market. The project will consist of over 2500 Li-ion battery packs each holding 3.7 kWh of LFP Li-ion prismatic modules. Powin is working with Eaton to supply the power conversion, transformer and switch gear equipment.

"Powin Energy is honored to have the opportunity to work closely with the city of Irvine, CAISO and SCE to bring this critical infrastructure project online by the end of the year. In addition to the immediate system benefits, this project will provide a valuable demonstration of the transformative potential of energy storage systems like ours to quickly bring clean, quiet, safe and firm energy service to areas where they are most needed," said Geoff Brown, President of Powin Energy. "We are particularly eager to demonstrate how our bp-OS software and cell-level control will provide unparalleled insight into the system's performance and maximize the system's life."
