🌿 BiomassIndustrial CHP44 MW capacity

90th largest plant in North Carolina · 3811th nationally

International Paper Riegelwood Mill is a biomass power plant in North Carolina with a nameplate capacity of 44.0 MW. It generates roughly 379.8k MWh per year — enough to power about 36,166 average U.S. homes.

Its capacity factor of 99% means it runs nearly around-the-clock as baseload generation. At 91 lb CO₂/MWh, its emission rate sits below 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.
