PowerSecure Delivers Smart Charging Micro-Grid to U.S. Army

Wake Forest, N.C. — April 11, 2011 — PowerSecure International, Inc. (Nasdaq: POWR) announced the commissioning of a state-of-the-art Smart Charging Micro-Grid for the U.S. Army, in a recent ceremony at Wheeler Army Airfield in Hawaii. The breakthrough technology was developed to help the U.S. Army reduce fuel consumption and costs, and improve safety and power reliability at remote U.S. Army locations. Additionally, it incorporates the use of renewable resources, including solar and optional wind power, and enables electric vehicles to be charged by, and provide power to the Micro-Grid system. The technology demonstrated in this system can be applied to power management applications for military field locations.

The Smart Charging Micro-Grid provides energy autonomy for facilities in remote locations, improving power availability and reliability. It is designed to enable reductions in the number and sizes of generators required to power facilities, and to control a wide range of generator types, providing significant battlefield flexibility. Additionally, it utilizes advanced energy storage to maximize the use of renewable power resources. The system has the ability to prioritize electrical load to individual receptacles, so the distribution of electricity can be optimized to maximize reliability and optimize fuel efficiency. Importantly, it will improve troop safety because of its ability to reduce fuel consumption and therefore reduce the number of convoys needed to transport fuel.

Sidney Hinton, CEO of PowerSecure, said, “We are excited to work with the U.S. Army to deliver this first-of-a-kind technology. The Smart Charging Micro-Grid is designed to improve fuel efficiency, power reliability, and utilize renewables — with the ultimate goal of reducing cost and improving battlefield safety. We have invested significant time and resources in its development, and look forward to continuing to perfect and enhance the system through this first large scale installation to battlefield ready status.”
