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.
Ghost bars are each month's theoretical maximum (84.2 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.
