Southampton Power Station

🌿 BiomassElectric Utility71 MW capacity

66th largest plant in Virginia · 3160th nationally

Southampton Power Station is a biomass power plant in Virginia with a nameplate capacity of 71.1 MW. It generates roughly 340.0k MWh per year — enough to power about 32,381 average U.S. homes.

Its capacity factor of 55% puts it in the middle range — running steadily but not full-time. At 18 lb CO₂/MWh, its emission rate sits below the national grid average of roughly 800 lb/MWh.

About Biomass plants

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.
