🌿 BiomassIndustrial CHP84 MW capacity

48th largest plant in Louisiana · 2758th nationally

Plant 31 Paper Mill is a biomass power plant in Louisiana with a nameplate capacity of 84.2 MW. It generates roughly 490.9k MWh per year — enough to power about 46,753 average U.S. homes.

Its capacity factor of 67% puts it in the middle range — running steadily but not full-time. At 322 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.
