Wheelabrator Bridgeport

🌿 BiomassIPP Non-CHP67 MW capacity

21st largest plant in Connecticut · 3233rd nationally

Wheelabrator Bridgeport is a biomass power plant in Connecticut with a nameplate capacity of 67.0 MW. It generates roughly 462.8k MWh per year — enough to power about 44,079 average U.S. homes.

Its capacity factor of 79% puts it in the middle range — running steadily but not full-time. At 1856 lb CO₂/MWh, its emission rate sits above 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.
