80th largest plant in Maine · 6987th nationally
Mmwac Resource Recovery Facility is a biomass power plant in Maine with a nameplate capacity of 5.0 MW. It generates roughly 11.6k MWh per year — enough to power about 1,107 average U.S. homes.
Its capacity factor of 27% reflects intermittent or peaking operation. At 6888 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 (5.0 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.
