How SUWANNEE RIVER compares
With 331 MW of capacity, SUWANNEE RIVER ranks 42nd among the 110 operating power plants Bywatts maps in Florida and 30th of the 55 operating Natural Gas plants in the state. It accounts for about 0.7% of Florida's operating Natural Gas capacity and 0.5% of all operating capacity in the state. Nationally it is the 431st-largest of the 1,185 operating Natural Gas plants in the database. Commissioned in 1980, it is older than 71% of the 108 operating Florida plants with a recorded commissioning year. Its operator, DUKE ENERGY FLORIDA, INC, runs 10 operating plants in Florida totaling 11,233 MW.
EIA-860 lists 3 generators at the site with 198 MW of nameplate capacity, mainly natural gas fired combustion turbine technology (this page's HIFLD capacity figure is 331 MW). Net generation was 76 GWh in 2024 (a 4.4% capacity factor).
