65th largest plant in Florida · 2631st nationally
Fernandina Beach Mill is a biomass power plant in Florida with a nameplate capacity of 96.9 MW. It generates roughly 557.7k MWh per year — enough to power about 53,116 average U.S. homes.
Its capacity factor of 66% puts it in the middle range — running steadily but not full-time. At 207 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 (96.9 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.
