US Navy Awards $97M Contract to Build Battery Storage Microgrid on Guam Base
The Naval Facilities Engineering Command has awarded a contract to Granite Construction and Obayashi Corp. to build out battery energy storage system (BESS) capacity and microgrid capabilities at Polaris Point, Guam.
The contract is worth approximately $97 million. The contractors will build a 17,000-square-foot BESS military microgrid which will be interconnected with the existing grid at the facility.
The additional equipment will include a microgrid controller. Work is scheduled to begin next week and be completed by June 2028.
Naval Base Guam is located on the island 3,300 miles west of Hawaii and 1,500 miles east of the Philippines. It is the westernmost U.S. territory.
Along with Andersen Air Force Base, it forms Joint Region Marianas. The Polaris Point part of the naval base is home to Submarine Squadron 15.
Other units include Coast Guard Sector Guam and Naval Special Warfare Unit One. Altogether, the U.S. military has multiple Air Force and Naval installations on Guam.
In 2022, the U.S. Navy and Marine Corps both announced plans to build cybersecure microgrids at critical military installations. The U.S. Army’s climate strategy also aims for a microgrid at nearly every installation by 2035.
