The U.S. Army is partnering with the U.S. Department of Energy’s (DOE) National Renewable Energy Laboratory (NREL) on a new Net Zero Energy Installation (NZEI) initiative to improve energy efficiency and renewable energy strategies at nine sites in the Army’s portfolio. If all nine pilot sites achieve net zero energy, they will replace approximately 8 percent of the Army’s current total installation energy use with renewable energy.

The NZEI pilot sites serve as test cases for broader market adoption. According to NREL, if all Army installations worldwide were to achieve a 25 percent reduction in energy consumption, the Army would save approximately 20 trillion BTUs and up to $300 million in annual energy costs.

The DOE’s Federal Energy Management Program supports the project’s efforts to replicate the technologies used in the pilot sites across the Department of Defense and other federal agencies.

Six of the Army pilot sites are focusing solely on net zero energy: Camp Parks Reserve Forces Training Area (Calif.), Fort Detrick (Md.), Fort Hunter Liggett (Calif.), Kwajalein Atoll (Republic of the Marshall Islands), Sierra Army Depot (Calif.), and West Point (N.Y.). Three other sites volunteered for unique net zero energy initiatives. Oregon Army National Guard is piloting a net zero energy initiative that includes all of its installations across the state, while Fort Bliss (Texas) and Fort Carson (Colo.) are piloting integrated net zero energy, water and waste programs.
