VALMONT COMBUSTION TURBINE PROJECT, a 142 MW Natural Gas power plant in Boulder County, Colorado. Operated by SWG COLORADO LLC, commissioned 2000.

How VALMONT COMBUSTION TURBINE PROJECT compares

With 142 MW of capacity, VALMONT COMBUSTION TURBINE PROJECT ranks 34th among the 114 operating power plants Bywatts maps in Colorado and 13th of the 21 operating Natural Gas plants in the state. It accounts for about 2.6% of Colorado's operating Natural Gas capacity and 0.9% of all operating capacity in the state. Nationally it is the 614th-largest of the 1,185 operating Natural Gas plants in the database. Commissioned in 2000, it is newer than 55% of the 111 operating Colorado plants with a recorded commissioning year. Its operator, SWG COLORADO LLC, runs 2 operating plants in Colorado totaling 336 MW. It shares Boulder County with 6 other operating plants, including UNIVERSITY OF COLORADO and BOULDER CITY LAKEWOOD HYDRO.

EIA-860 lists 2 generators at the site with 142 MW of nameplate capacity, all natural gas fired combustion turbine technology. Net generation was 46 GWh in 2024 (a 3.7% capacity factor). Its generators came online between 2000 and 2001.

Weather peril exposure

VALMONT COMBUSTION TURBINE PROJECT is a 142 MW natural gas power plant in Boulder County, CO, operated by SWG COLORADO LLC, commissioned in 2000. Boulder County carries critical modeled catastrophe exposure in the FEMA National Risk Index, scoring 4.5 of 5 at the 86th national percentile. Wildfire is the leading peril, rated Relatively High by FEMA at the 95th 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.
