COMBINED LOCKS ENERGY CENTER, a 53 MW Natural Gas power plant in Outagamie County, Wisconsin. Operated by WPS POWER DEVELOPMENT, commissioned 2002.
How COMBINED LOCKS ENERGY CENTER compares
With 53 MW of capacity, COMBINED LOCKS ENERGY CENTER ranks 40th among the 141 operating power plants Bywatts maps in Wisconsin and 19th of the 26 operating Natural Gas plants in the state. It accounts for about 0.8% of Wisconsin's operating Natural Gas capacity and 0.3% of all operating capacity in the state. Nationally it is the 798th-largest of the 1,185 operating Natural Gas plants in the database. Commissioned in 2002, it is newer than 79% of the 141 operating Wisconsin plants with a recorded commissioning year. It shares Outagamie County with 11 other operating plants, including FOX ENERGY CENTER and ISLAND STREET PEAKING PLANT.
EIA-860 lists 2 generators at the site with 67 MW of nameplate capacity, all natural gas fired combined cycle technology (this page's HIFLD capacity figure is 53 MW). Net generation was 310 GWh in 2024 (a 53% capacity factor), down 5% from 2022.

Weather peril exposure
COMBINED LOCKS ENERGY CENTER is a 53 MW natural gas power plant in Outagamie County, WI, operated by WPS POWER DEVELOPMENT, commissioned in 2002. Outagamie County carries high modeled catastrophe exposure in the FEMA National Risk Index, scoring 3.5 of 5 at the 62nd national percentile. Hail is the leading peril, rated Relatively Moderate by FEMA at the 70th 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.
