Leaf River Cellulose Llc

🌿 BiomassIndustrial CHP50 MW capacity

40th largest plant in Mississippi · 3561st nationally

Leaf River Cellulose Llc is a biomass power plant in Mississippi with a nameplate capacity of 50.4 MW. It generates roughly 421.2k MWh per year — enough to power about 40,112 average U.S. homes.

Its capacity factor of 95% means it runs nearly around-the-clock as baseload generation. At 26 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.
