CIMARRON RIVER, a 65 MW Natural Gas power plant in Seward County, Kansas. Operated by SUNFLOWER ELECTRIC POWER CORP, commissioned 1963.
How CIMARRON RIVER compares
With 65 MW of capacity, CIMARRON RIVER ranks 38th among the 115 operating power plants Bywatts maps in Kansas and 13th of the 53 operating Natural Gas plants in the state. It accounts for about 1.7% of Kansas's operating Natural Gas capacity and 0.5% of all operating capacity in the state. Nationally it is the 758th-largest of the 1,185 operating Natural Gas plants in the database. Commissioned in 1963, it is older than 66% of the 113 operating Kansas plants with a recorded commissioning year. Its operator, SUNFLOWER ELECTRIC POWER CORP, runs 7 operating plants in Kansas totaling 1,000 MW. It shares Seward County with one other operating plant, ARKALON ETHANOL LLC.
EIA-860 lists 2 generators at the site with 65 MW of nameplate capacity, mainly natural gas steam turbine technology. Net generation was 57.7 GWh in 2024 (a 10% capacity factor). Its generators came online between 1963 and 1968.
Grid neighborhood
The closest transmission line found within 10 miles is a 115 kV line, under 0.1 miles away. One other operating power plant sits within 25 miles: ARKALON ETHANOL LLC (3 MW).

Weather peril exposure
CIMARRON RIVER is a 65 MW natural gas power plant in Seward County, KS, operated by SUNFLOWER ELECTRIC POWER CORP, commissioned in 1963. Seward County carries critical modeled catastrophe exposure in the FEMA National Risk Index, scoring 4.6 of 5 at the 91st national percentile. Hail is the leading peril, rated Relatively Moderate by FEMA at the 92nd 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.
Seward County hazard ratings
| Peril | FEMA rating | National percentile | Peril score | Events per year |
|---|---|---|---|---|
| Hail | Relatively Moderate | 92nd | 4.7 of 5 | 9.5 |
| Wildfire | Relatively Low | 91st | 4.7 of 5 | <0.01 |
| Strong wind | Relatively Moderate | 87th | 4.5 of 5 | 4.6 |
| Winter weather | Relatively Low | 80th | 4.2 of 5 | 9.7 |
| Tornado | Relatively Moderate | 77th | 4.1 of 5 | 0.53 |
| Ice storm | Relatively Low | 73rd | 3.9 of 5 | 0.46 |
| Heat wave | Very Low | 71st | 3.8 of 5 | 0.95 |
| Earthquake | Very Low | 43rd | 2.7 of 5 | <0.01 |
| Lightning | Relatively Moderate | 34th | 2.4 of 5 | 43.1 |
| Riverine flooding | Very Low | 2nd | 1.1 of 5 | 0.39 |
Perils not assessed in Seward County
These perils carry no usable National Risk Index figure for this county, so they are excluded from the scoring rather than scored zero. A zero would claim the peril was assessed and found benign.
| 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 |
