36th largest plant in New Jersey · 4487th nationally
Middlesex County Utilities Authority is a biomass power plant in New Jersey with a nameplate capacity of 22.5 MW. It generates roughly 99.4k MWh per year — enough to power about 9,464 average U.S. homes.
Its capacity factor of 50% puts it in the middle range — running steadily but not full-time. At 0 lb CO₂/MWh, its emission rate sits below the national grid average of roughly 800 lb/MWh.
Ghost bars are each month's theoretical maximum (22.5 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.
