RALPH GREEN, a 74 MW Natural Gas power plant in Cass County, Missouri. Operated by KCP&L GREATER MISSOURI OPERATIONS CO, commissioned 1981.
How RALPH GREEN compares
With 74 MW of capacity, RALPH GREEN ranks 34th among the 92 operating power plants Bywatts maps in Missouri and 14th of the 23 operating Natural Gas plants in the state. It accounts for about 1.4% of Missouri's operating Natural Gas capacity and 0.4% of all operating capacity in the state. Nationally it is the 743rd-largest of the 1,185 operating Natural Gas plants in the database. Commissioned in 1981, it is newer than 52% of the 89 operating Missouri plants with a recorded commissioning year. Its operator, KCP&L GREATER MISSOURI OPERATIONS CO, runs 6 operating plants in Missouri totaling 966 MW. It shares Cass County with 2 other operating plants, DOGWOOD ENERGY FACILITY and SOUTH HARPER.
EIA-860 lists 1 generator at the site with 89 MW of nameplate capacity, all natural gas fired combustion turbine technology (this page's HIFLD capacity figure is 74 MW). Net generation was 49.9 GWh in 2024 (a 6.4% capacity factor).

Weather peril exposure
RALPH GREEN is a 74 MW natural gas power plant in Cass County, MO, operated by KCP&L GREATER MISSOURI OPERATIONS CO, commissioned in 1981. Cass County carries critical modeled catastrophe exposure in the FEMA National Risk Index, scoring 4.4 of 5 at the 86th national percentile. Hail is the leading peril, rated Relatively Moderate by FEMA at the 88th 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.
Cass County hazard ratings
| Peril | FEMA rating | National percentile | Peril score | Events per year |
|---|---|---|---|---|
| Hail | Relatively Moderate | 88th | 4.5 of 5 | 8.2 |
| Winter weather | Relatively Moderate | 84th | 4.3 of 5 | 11.2 |
| Tornado | Relatively Moderate | 79th | 4.2 of 5 | 0.42 |
| Heat wave | Relatively Moderate | 74th | 4.0 of 5 | 14.9 |
| Ice storm | Relatively Moderate | 67th | 3.7 of 5 | 0.87 |
| Lightning | Relatively Moderate | 50th | 3.0 of 5 | 51.3 |
| Riverine flooding | Relatively Low | 45th | 2.8 of 5 | 1.8 |
| Earthquake | Very Low | 39th | 2.5 of 5 | <0.01 |
| Wildfire | Very Low | 18th | 1.7 of 5 | <0.01 |
| Strong wind | Relatively High | 13th | 1.5 of 5 | 6.1 |
| Hurricane | Very Low | 5th | 1.2 of 5 | <0.01 |
Perils not assessed in Cass County
