40th largest plant in Connecticut · 4940th nationally
Covanta Southeastern Connecticut Company is a biomass power plant in Connecticut with a nameplate capacity of 18.3 MW. It generates roughly 114.2k MWh per year — enough to power about 10,880 average U.S. homes.
Its capacity factor of 71% puts it in the middle range — running steadily but not full-time. At 2437 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 (18.3 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.
