CLEWISTON SUGAR HOUSE, a 71 MW Biomass power plant in Hendry County, Florida. Operated by UNITED STATES SUGAR CORP, commissioned 2004.
How CLEWISTON SUGAR HOUSE compares
With 71 MW of capacity, CLEWISTON SUGAR HOUSE ranks 63rd among the 110 operating power plants Bywatts maps in Florida and 6th of the 21 operating Biomass plants in the state. It accounts for about 7.4% of Florida's operating Biomass capacity and 0.1% of all operating capacity in the state. Nationally it is the 43rd-largest of the 350 operating Biomass plants in the database. Commissioned in 2004, it is newer than 75% of the 108 operating Florida plants with a recorded commissioning year.
EIA-860 lists 3 generators at the site with 49 MW of nameplate capacity, all other waste biomass technology (this page's HIFLD capacity figure is 71 MW). Net generation was 271 GWh in 2024 (a 63% capacity factor), up 1% from 2022. Its generators came online between 2004 and 2007.
Grid neighborhood
The closest transmission line found within 10 miles is a 138 kV line, about 0.3 miles away. One other operating power plant sits within 25 miles: OKEELANTA COGENERATION (129 MW, Biomass).

Weather peril exposure
CLEWISTON SUGAR HOUSE is a 71 MW biomass power plant in Hendry County, FL, operated by UNITED STATES SUGAR CORP, commissioned in 2004. Hendry County carries elevated modeled catastrophe exposure in the FEMA National Risk Index, scoring 3.3 of 5 at the 57th national percentile. Hurricane is the leading peril, rated Relatively High by FEMA at the 93rd percentile.
The Bywatts loss layer is calibrated to solar PV hardware, so it is not applied to a biomass plant. The ratings below are the FEMA National Risk Index county hazard ratings for this location.
