GADSBY, a 433 MW Natural Gas power plant in Salt Lake County, Utah. Operated by PACIFICORP, commissioned 1951.

How GADSBY compares

With 433 MW of capacity, GADSBY ranks 7th among the 61 operating power plants Bywatts maps in Utah and 3rd of the 14 operating Natural Gas plants in the state. It accounts for about 20% of Utah's operating Natural Gas capacity and 5.7% of all operating capacity in the state. Nationally it is the 357th-largest of the 1,185 operating Natural Gas plants in the database. Commissioned in 1951, it is older than 78% of the 61 operating Utah plants with a recorded commissioning year. Its operator, PACIFICORP, runs 11 operating plants in Utah totaling 4,139 MW. It shares Salt Lake County with 10 other operating plants, including WEST VALLEY GENERATION PROJECT and MURRAY TURBINE.

EIA-860 lists 6 generators at the site with 433 MW of nameplate capacity, mainly natural gas steam turbine technology. Net generation was 345 GWh in 2024 (a 9.1% capacity factor). Its generators came online between 1951 and 2002.

Weather peril exposure

GADSBY is a 433 MW natural gas power plant in Salt Lake County, UT, operated by PACIFICORP, commissioned in 1951. Salt Lake County carries low modeled catastrophe exposure in the FEMA National Risk Index, scoring 1.6 of 5 at the 15th national percentile. Earthquake is the leading peril, rated Relatively High by FEMA at the 97th 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.
