Environment and Energy Resilience
Installation Energy

The Office of the Deputy Assistant Secretary of Defense for Environment and Energy Resilience (ODASD(E&ER)) oversees the Department of Defense (DoD) programs related to installation energy, water and the cybersecurity of facility related control systems. ODASD(E&ER) is responsible for issuing policy and guidance, coordinating the Defense Department’s Installation Energy Strategy, engaging with DoD Components, and coordinating all congressional reports related to ODASD(E&ER) programs.

Our Mission

Ensure DoD mission readiness with resilient, reliable, clean and efficient installation energy capabilities that can recover quickly from disruptions, through data-driven and climate informed projects and programs.

DoD's Installation Energy Strategy

The DoD operates buildings and facilities at over 500 military installations in the United States and overseas. The Department’s inventory is diverse, encompassing barracks, commissaries, data centers, office buildings, laboratories, and aircraft maintenance depots. Installation energy consists largely of traditional energy sources used to heat, cool, and provide electrical power to these buildings. It also includes the fuel used by non-tactical vehicles housed at DoD installations. The Department spends over $4 billion a year on energy at fixed installations. These installations are largely dependent on a commercial power grid that is vulnerable to disruption from aging infrastructure, weather-related events and direct attack.

ODASD(E&ER) implements the DoD’s installation energy strategy to ensure mission assurance for the warfighter, reduce energy costs, and improve the energy and climate resilience of our fixed installations. DoD’s installation energy strategy includes:

This strategy supports the Department’s strategic goals and the Nation’s energy security goals. Successful implementation of this strategy will improve energy performance at DoD installations and ultimately lower energy and water costs, stimulate energy technology innovation in the private sector, improve mission assurance through energy and water resilience of our military bases and ensure the cyber security of facility related control systems.
