U.S. Army Invests in 1MW Energy Storage System to Complement 10MW Solar Power Plant

Wednesday, 23 August 2017

California-based SunPower Corp. has broken ground on a 10MW solar photovoltaic system at the Redstone Arsenal U.S. Army post in Alabama. With a newly added 1MW energy storage system, the project is designed to strengthen energy security and resilience at Redstone Arsenal.

“This project reinforces the Army’s commitment to advancing adoption of reliable, cost-effective, home-grown renewable energy at Redstone Arsenal,” said Col. Thomas Holliday, Garrison Commander, Redstone Arsenal. “We’re continually looking for ways to grow our capability and reduce our cost to provide the nation with a more efficient defense.”

Developed by the U.S. Army Office of Energy Initiatives, Redstone Arsenal’s Directorate of Public Works, and the U.S. Army Corps of Engineers Huntsville Center’s Energy Division, the project was financed by a power purchase agreement (PPA), allowing the Army to buy 100% of the power generated without having to pay for the construction, maintenance and operation.

“Solar is cost-competitive with traditional energy sources today, and is helping the U.S. military reduce operational costs,” said Nam Nguyen, SunPower executive vice president. “We commend Redstone Arsenal for managing its significant energy demand with abundant, renewable solar power. The high performance solar and storage technology we are installing for the agency will substantially increase the value of energy produced by the solar plant over the long term.”

SunPower designed and is installing a SunPower® Oasis® Power Plant system at the site, which is a fully-integrated, modular solar power block engineered and built for compatibility with a future micro-grid. SunPower has designed and installed solar power systems at a number of military facilities including more than 28MWs at Nellis Air Force Base in Nevada and 13.78MWs at Naval Air Weapons Station China Lake in California, as well as 28MWs currently under construction at Vandenberg Air Force Base.
