U.S. Army Invests in 1-Megawatt Energy Storage System to Complement 10-Megawatt SunPower Solar Power Plant at Redstone Arsenal

Army's First Privately Funded, Commercially Available Storage Solution Expected to Help Reduce Peak Power Demand Charges While Increasing Energy Security at the Base

SAN JOSE, Calif., Aug. 23, 2017 /PRNewswire/ -- SunPower Corp. (NASDAQ: SPWR) has broken ground on a 10-megawatt solar photovoltaic system at the Redstone Arsenal U.S. Army post in Alabama which is expected to create more than 200 jobs at peak of construction. With a newly added 1-megawatt energy storage system, the project is designed to strengthen energy security and resilience at Redstone Arsenal, supporting the Army's efforts to reduce electricity costs at installations while also making them more energy independent.


"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 innovative project was financed by a power purchase agreement (PPA), allowing the Army to buy 100 percent of the power generated without having to pay for the power plant's construction, maintenance and operation. The Army continues to collaborate with private-sector partners and utilities to build clean, alternative energy projects including onsite power generation, electricity storage, and energy control.

"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, further contributing to the overall energy security of the installation.

As a trusted solar advisor to federal government agencies and the Department of Defense, SunPower has designed and installed solar power systems at a number of military facilities including more than 28 megawatts at Nellis Air Force Base in Nevada and 13.78 megawatts at Naval Air Weapons Station China Lake in California, as well as 28 megawatts currently under construction at Vandenberg Air Force Base.

SolarEdge Technologies - Solar Inverters, Power Optimizers and PV Monitoring

The SolarEdge PV inverter combines sophisticated digital control technology with efficient power conversion architecture to achieve superior solar power harvesting and best-in-class reliability. The fixed-voltage technology ensures the solar inverter is always working at its optimal input voltage over a wider range of string lengths and regardless of environmental conditions. A proprietary data monitoring receiver has been integrated into the inverter and aggregates the power optimizer performance data from each PV module. This data can be transmitted to the web and accessed via the SolarEdge Monitoring Portal for performance analysis, fault detection and troubleshooting of PV systems.
