Union County Resource Recovery

🌿 BiomassCommercial Non-CHP45 MW capacity

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.

About Biomass plants

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.
