Redstone Arsenal and SunPower Corp. placed into service a 10 megawatt (MW) solar photovoltaic and 1 MW energy storage system at the U.S. Army post in Alabama.

The solar array and storage project was designed, built and will be operated and maintained by SunPower, with financing by Regions Bank.

The project is a collaboration between the U.S. Army Office of Energy Initiatives, Redstone Arsenal, the U.S. Army Corps of Engineers and SunPower. A modular solar power block is engineered and built for compatibility with a future microgrid, and is paired with storage to reduce peak power-related demand charges for Redstone Arsenal.

The Army is buying 100 percent of the electricity generated by the project through a 27-year power purchase agreement (PPA) at rates said to be competitive with traditional energy sources.

SunPower has deployed solar power systems at other military facilities, including more than 28 MW at Nellis Air Force Base in Nevada, 13.78 MW at Naval Air Weapons Station China Lake and 28 MW at Vandenberg Air Force Base in California.
