33rd largest plant in Massachusetts · 3762nd nationally
Covanta Haverhill is a biomass power plant in Massachusetts with a nameplate capacity of 46.0 MW. It generates roughly 339.4k MWh per year — enough to power about 32,320 average U.S. homes.
Its capacity factor of 84% means it runs nearly around-the-clock as baseload generation. At 1810 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 (46.0 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.
