32nd largest plant in New Jersey · 3784th nationally
Union County Resource Recovery is a biomass power plant in New Jersey with a nameplate capacity of 45.0 MW. It generates roughly 298.4k MWh per year — enough to power about 28,414 average U.S. homes.
Its capacity factor of 76% puts it in the middle range — running steadily but not full-time. At 2008 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 (45.0 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.
