ELECTRIFARM, a 264 MW Natural Gas power plant in Black Hawk County, Iowa. Operated by MIDAMERICAN ENERGY CO, commissioned 1975.
How ELECTRIFARM compares
With 264 MW of capacity, ELECTRIFARM ranks 13th among the 198 operating power plants Bywatts maps in Iowa and 3rd of the 22 operating Natural Gas plants in the state. It accounts for about 11% of Iowa's operating Natural Gas capacity and 1.7% of all operating capacity in the state. Nationally it is the 492nd-largest of the 1,185 operating Natural Gas plants in the database. Commissioned in 1975, it is older than 70% of the 198 operating Iowa plants with a recorded commissioning year. Its operator, MIDAMERICAN ENERGY CO, runs 28 operating plants in Iowa totaling 8,028 MW. It shares Black Hawk County with 5 other operating plants, including STREETER STATION and GAS TURBINE.
EIA-860 lists 3 generators at the site with 264 MW of nameplate capacity, all natural gas fired combustion turbine technology. Net generation was 11 GWh in 2024 (a 0.5% capacity factor). Its generators came online between 1975 and 1978.

Weather peril exposure
ELECTRIFARM is a 264 MW natural gas power plant in Black Hawk County, IA, operated by MIDAMERICAN ENERGY CO, commissioned in 1975. Black Hawk County carries elevated modeled catastrophe exposure in the FEMA National Risk Index, scoring 2.8 of 5 at the 45th national percentile. Tornado is the leading peril, rated Relatively High by FEMA at the 89th 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.
Black Hawk County hazard ratings
| Peril | FEMA rating | National percentile | Peril score | Events per year |
|---|---|---|---|---|
| Tornado | Relatively High | 89th | 4.6 of 5 | 0.54 |
| Heat wave | Relatively Low | 88th | 4.5 of 5 | 3.9 |
| Lightning | Relatively Low | 74th | 4.0 of 5 | 41.6 |
| Winter weather | Relatively High | 64th | 3.5 of 5 | 17.8 |
| Strong wind | Relatively High | 57th | 3.3 of 5 | 5.3 |
| Hail | Relatively Moderate | 54th | 3.2 of 5 | 5.0 |
| Ice storm | Relatively Moderate | 44th | 2.8 of 5 | 0.31 |
| Riverine flooding | Relatively Moderate | 27th | 2.1 of 5 | 4.5 |
| Wildfire | Very Low | 25th | 2.0 of 5 | <0.01 |
