Title 10 › Subtitle A — General Military Law › PART IV — SERVICE, SUPPLY, AND PROPERTY › CHAPTER 173 — ENERGY SECURITY › SUBCHAPTER I — ENERGY SECURITY ACTIVITIES › § 2920
The Secretary of Defense must make sure that by the end of fiscal year 2030, all energy needed to run each base’s critical missions is available at least 99.9 percent of the time each year. The Secretary will set specific availability levels for different missions, anywhere from 99.9 percent up to 99.9999 percent depending on how important the mission is. The Department can set interim goals before fiscal year 2025. Each military branch and Defense Agency must meet these rules. The Department must work with outside power planners and regulators, find which loads and systems are mission-critical, and plan how to reduce risks. Plans must prefer many different energy sources, favor energy made on the base (like modular generators), encourage microgrids, and use full-time installed power rather than only emergency generators. Bases must list their critical missions, how much energy those missions need, how long that energy would be needed in an emergency, current energy sources and how long they would last, and what backup or new sources could provide uninterrupted power. The military must monitor, measure, and test energy systems and share data when asked. They must run “black start” exercises that cut off off-base power and prove backup systems can start and run critical missions; these exercises can skip housing and some support facilities if possible. The Department will give one policy for these exercises and set a schedule so each military department runs them on at least five installations each year through fiscal year 2032. Each exercise should not last more than five days. Energy and utility contracts must include ways to measure and verify energy use, availability, and reliability. Fuels for aircraft, ships, or motor vehicles are not covered. If by the end of fiscal year 2027 the Secretary thinks the Department cannot meet the 2030 goals, the Secretary must send a report to the Senate and House Armed Services Committees within 90 days after that fiscal year ends. The report must say how big the shortfall is, why it will happen, any legal, technical, or money problems, how readiness or defense posture will be affected, and any other relevant facts. Short definitions: availability means how much energy is ready when needed; black start exercise means testing startup of on-base backup power after cutting off off-base power; critical mission means the most essential base tasks for national defense (examples include headquarters, airfields, munitions, radars, cyber or space facilities); energy means electricity, natural gas, steam, chilled water, and heated water; installation means a military installation as defined elsewhere.
