31st largest plant in South Carolina · 2391st nationally
Florence Mill is a biomass power plant in South Carolina with a nameplate capacity of 104 MW. It generates roughly 393.9k MWh per year — enough to power about 37,509 average U.S. homes.
Its capacity factor of 43% puts it in the middle range — running steadily but not full-time. At 97 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 (104 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.
