Powin Energy to Install 6.5-MW Energy Storage in California

By Editors of Power Engineering

Powin Energy has entered into a contract with San Diego Gas & Electric to deliver a 6.5 MW/26 MW/h battery energy storage system in Escondido, California.

The project is subject to approval by the California Public Utilities Commission.

The proposed system will improve reliability on the existing electrical grid by optimizing the intermittent output of renewable energy sources, and allow SDG&E additional flexibility for its energy sources.

“I appreciate the confidence SDG&E has shown in Powin Energy by selecting us for this important project. We continue to find that utilities and IPPs see tremendous value in the fact we do our own engineering, software development, and manufacturing. It makes it easy for us to be adaptable to a given project’s unique requirements rather than offering one-size-fits-all solutions,” said Geoffrey Brown, president of Powin Energy.

CPUC has mandated SDG&E procure at least 165 MW of energy storage by 2020 and have all projects operational by 2024. To date, the utility has over 94 MW of deployed or contracted energy storage over 20 projects.

Powin Energy’s Stack140 is a modular, purpose-built 140 kWh battery array that scales from 125 kW to multiple megawatt applications. It is available in both indoor and NEMA 3R outdoor models, each of which is engineered to maximize energy density and minimize system footprint.
