Powin to supply a 6.5 MW battery for SDG&E

The energy storage provider has inked a deal to provide a 6.5 MW / 26 MWh battery in Escondido, after installing a smaller system for SCE earlier this year.

While grid-tied battery deployment has been rising in the United States for years, the technology got a big boost by one of the nation’s worst disasters as far as climate impacts go: The Aliso Canyon gas leak.

This leak of nearly 100,000 tons of methane into the atmosphere did not only shoot up California’s greenhouse gas emissions, but also wiped out gas storage, which led to an emergency deployment of large amounts of battery storage. This included some of the world’s largest battery storage systems.

But that was not the end of energy storage deployments in California. Today Powin Energy reported that it has signed a contract with San Diego Gas & Electric Company (SDG&E) to install a 6.5 MW / 26 megawatt-hour (MWh) battery system in Escondido, California. The company plans to supply its Stack140 modular battery system, which comes in 140 kWh arrays.

This follows on Powin’s supply of a 2 MW / 8 MWh battery system for Southern California Edison (SCE) earlier this year, as part of the utility’s response to the Aliso Canyon leak.
