KALAMAZOO RIVER GENERATING STATION, a 73 MW Natural Gas power plant in Kalamazoo County, Michigan. Operated by CMS GENERATION MI POWER LLC, commissioned 1999.
How KALAMAZOO RIVER GENERATING STATION compares
With 73 MW of capacity, KALAMAZOO RIVER GENERATING STATION ranks 32nd among the 171 operating power plants Bywatts maps in Michigan and 16th of the 29 operating Natural Gas plants in the state. It accounts for about 0.8% of Michigan's operating Natural Gas capacity and 0.3% of all operating capacity in the state. Nationally it is the 744th-largest of the 1,185 operating Natural Gas plants in the database. Commissioned in 1999, it is newer than 75% of the 168 operating Michigan plants with a recorded commissioning year. Its operator, CMS GENERATION MI POWER LLC, runs 2 operating plants in Michigan totaling 243 MW. It shares Kalamazoo County with one other operating plant, WESTERN MICHIGAN UNIVERSITY POWER PLANT.
EIA-860 lists 1 generator at the site with 77 MW of nameplate capacity, all natural gas fired combustion turbine technology. Net generation was 245 GWh in 2024 (a 36% capacity factor), about 2.3 times its 2022 output.

Weather peril exposure
KALAMAZOO RIVER GENERATING STATION is a 73 MW natural gas power plant in Kalamazoo County, MI, operated by CMS GENERATION MI POWER LLC, commissioned in 1999. Kalamazoo County carries critical modeled catastrophe exposure in the FEMA National Risk Index, scoring 4.3 of 5 at the 81st national percentile. Hail is the leading peril, rated Relatively High by FEMA at the 85th 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.
Kalamazoo County hazard ratings
