36th largest plant in Massachusetts · 3888th nationally
Wheelabrator North Andover is a biomass power plant in Massachusetts with a nameplate capacity of 40.3 MW. It generates roughly 238.0k MWh per year — enough to power about 22,669 average U.S. homes.
Its capacity factor of 67% puts it in the middle range — running steadily but not full-time. At 2085 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 (40.3 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.
