microgrid project at the U.S. Army’s Ft. Bliss in Texas. The Department of Defense (DoD) Environmental Security Technology Certification Program funded Lockheed Martin’s microgrid demonstration and the Princeton Power storage system. The 20-foot containerized storage system consists of one 100-kW grid-tied inverter and multiple advanced lead-acid batteries, capable of producing 20 kWh of energy. In the event of a power outage, the storage system provides enough energy to power the base, and also provides power factor correction and area frequency regulation services to the local system operator while the system is connected to the electric grid.
