40th largest plant in Virginia · 2163rd nationally
Covanta Fairfax Energy is a biomass power plant in Virginia with a nameplate capacity of 124 MW. It generates roughly 690.0k MWh per year — enough to power about 65,716 average U.S. homes.
Its capacity factor of 64% puts it in the middle range — running steadily but not full-time. At 1894 lb CO₂/MWh, its emission rate sits above the national grid average of roughly 800 lb/MWh.
Ghost bars are each month's theoretical maximum (124 MW nameplate × hours in the month). Filled bars are actual net generation reported to EIA Form 923. The gap between them is capacity factor made visible.

Biomass plants burn wood, agricultural waste, or methane from landfills to generate steam and electricity. They are considered carbon-neutral over long timescales when fuel is sustainably sourced, but they produce particulate emissions similar to coal.
