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.
Ghost bars are each month's theoretical maximum (50.4 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.
