How NAUGHTON compares
With 707 MW of capacity, NAUGHTON ranks 4th among the 53 operating power plants Bywatts maps in Wyoming and 3rd of the 8 operating Coal plants in the state. It accounts for about 16% of Wyoming's operating Coal capacity and 8.2% of all operating capacity in the state. Nationally it is the 137th-largest of the 324 operating Coal plants in the database. Commissioned in 1963, it is older than 69% of the 53 operating Wyoming plants with a recorded commissioning year. Its operator, PACIFICORP, runs 10 operating plants in Wyoming totaling 4,823 MW. It shares Lincoln County with 4 other operating plants, including SHUTE CREEK FACILITY and FONTENELLE.
EIA-860 lists 3 generators at the site with 707 MW of nameplate capacity, mainly conventional steam coal technology. Net generation was 2,779 GWh in 2024 (a 45% capacity factor), up 13% from 2022. Its generators came online between 1963 and 1971.

Weather peril exposure
NAUGHTON is a 707 MW coal power plant in Lincoln County, WY, operated by PACIFICORP, commissioned in 1963. Lincoln County carries low modeled catastrophe exposure in the FEMA National Risk Index, scoring 1.3 of 5 at the 9th national percentile. Earthquake is the leading peril, rated Relatively Low by FEMA at the 94th percentile.
The Bywatts loss layer is calibrated to solar PV hardware, so it is not applied to a coal plant. The ratings below are the FEMA National Risk Index county hazard ratings for this location.
