GLENDIVE GT, an 86 MW Natural Gas power plant in Dawson County, Montana. Operated by MONTANA-DAKOTA UTILITIES CO, commissioned 1979.
How GLENDIVE GT compares
With 86 MW of capacity, GLENDIVE GT ranks 16th among the 48 operating power plants Bywatts maps in Montana and is the largest of the 4 operating Natural Gas plants in the state. It accounts for about 52% of Montana's operating Natural Gas capacity and 1.4% of all operating capacity in the state. Nationally it is the 711th-largest of the 1,185 operating Natural Gas plants in the database. Commissioned in 1979, it is older than 60% of the 46 operating Montana plants with a recorded commissioning year. Its operator, MONTANA-DAKOTA UTILITIES CO, runs 3 operating plants in Montana totaling 139 MW.
EIA-860 lists 2 generators at the site with 84 MW of nameplate capacity, all natural gas fired combustion turbine technology. Net generation was 2.6 GWh in 2024 (a 0.4% capacity factor). Its generators came online between 1979 and 2003.

Weather peril exposure
GLENDIVE GT is an 86 MW natural gas power plant in Dawson County, MT, operated by MONTANA-DAKOTA UTILITIES CO, commissioned in 1979. Dawson County carries elevated modeled catastrophe exposure in the FEMA National Risk Index, scoring 2.7 of 5 at the 44th national percentile. Winter weather is the leading peril, rated Relatively Moderate 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.
Dawson County hazard ratings
| Peril | FEMA rating | National percentile | Peril score | Events per year |
|---|---|---|---|---|
| Winter weather | Relatively Moderate | 97th | 4.9 of 5 | 18.8 |
| Heat wave | Relatively Low | 89th | 4.6 of 5 | 2.7 |
| Strong wind | Relatively Low | 83rd | 4.3 of 5 | 1.6 |
| Wildfire | Very Low | 72nd | 3.9 of 5 | <0.01 |
| Riverine flooding | Very Low | 54th | 3.2 of 5 | 1.0 |
| Hail | Relatively Low | 54th | 3.2 of 5 | 2.1 |
| Tornado | Very Low | 33rd | 2.3 of 5 | 0.23 |
| Ice storm | Very Low | 26th | 2.0 of 5 | 0.02 |
| Lightning | Relatively Moderate | 17th | 1.7 of 5 | 28.2 |
| Earthquake | Very Low | 15th | 1.6 of 5 | <0.01 |
Perils not assessed in Dawson County

| Peril | Why it is not scored |
|---|---|
| Hurricane | FEMA rating is "Not Applicable" for this county |
| Coastal flooding | FEMA rating is "Not Applicable" for this county |
