78th largest plant in Georgia · 3122nd nationally
Riverwood International Macon Mill is a biomass power plant in Georgia with a nameplate capacity of 73.4 MW. It generates roughly 359.3k MWh per year — enough to power about 34,220 average U.S. homes.
Its capacity factor of 56% puts it in the middle range — running steadily but not full-time. At 73 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 (73.4 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.
