District of Columbia's generating fleet in context

The District of Columbia has 72 megawatts of nameplate capacity across 21 plants, ranking it smallest among the 51 U.S. states and territories. This is capacity — what the equipment could produce running at full output — not generation, which varies by fuel type and season. Solar makes up 48.8% of the fleet at 35 megawatts across 17 installations, while natural gas provides 31.7% at 23 megawatts across 3 plants. The remaining 19.5%, or 14 megawatts, comes from other sources in a single facility.

The largest plant is the Walt Bailey Bioenergy Facility at 14 megawatts, followed by US GSA Heating and Transmission at 11 megawatts on natural gas. The AOC, Capitol Power Plant adds 8 megawatts on natural gas, JBAB - Washington DC contributes 6 megawatts of solar capacity, and Ross Hall Central Utility Plant rounds out the top five at 5 megawatts on natural gas. The generating fleet spans from July 2004, when US GSA Heating and Transmission came online, through November 2025, when V Street Solar began operation.
