CASS COUNTY, a 345 MW Natural Gas power plant in Cass County, Nebraska. Operated by OMAHA PUBLIC POWER DISTRICT, commissioned 2003.
How CASS COUNTY compares
With 345 MW of capacity, CASS COUNTY ranks 5th among the 86 operating power plants Bywatts maps in Nebraska and is the largest of the 28 operating Natural Gas plants in the state. It accounts for about 20% of Nebraska's operating Natural Gas capacity and 4.1% of all operating capacity in the state. Nationally it is the 417th-largest of the 1,185 operating Natural Gas plants in the database. Commissioned in 2003, it is newer than 81% of the 85 operating Nebraska plants with a recorded commissioning year. Its operator, OMAHA PUBLIC POWER DISTRICT, runs 6 operating plants in Nebraska totaling 2,853 MW.
EIA-860 lists 2 generators at the site with 345 MW of nameplate capacity, all natural gas fired combustion turbine technology. Net generation was 202 GWh in 2024 (a 6.7% capacity factor), up 1% from 2022.

Weather peril exposure
CASS COUNTY is a 345 MW natural gas power plant in Cass County, NE, operated by OMAHA PUBLIC POWER DISTRICT, commissioned in 2003. Cass County carries critical modeled catastrophe exposure in the FEMA National Risk Index, scoring 4.6 of 5 at the 89th national percentile. Heat wave is the leading peril, rated Relatively Low by FEMA at the 96th percentile.
The Bywatts loss layer is calibrated to solar PV hardware, so it is not applied to a natural gas plant. The ratings below are the FEMA National Risk Index county hazard ratings for this location.
