INDIANOLA, a 54 MW Oil power plant in Warren County, Iowa. Operated by INDIANOLA MUNICIPAL UTILITIES, commissioned 1977.
How INDIANOLA compares
With 54 MW of capacity, INDIANOLA ranks 59th among the 198 operating power plants Bywatts maps in Iowa and 4th of the 77 operating Oil plants in the state. It accounts for about 5.7% of Iowa's operating Oil capacity and 0.3% of all operating capacity in the state. Nationally it is the 75th-largest of the 544 operating Oil plants in the database. Commissioned in 1977, it is older than 69% of the 198 operating Iowa plants with a recorded commissioning year.
EIA-860 lists 2 generators at the site with 41 MW of nameplate capacity, all petroleum liquids technology (this page's HIFLD capacity figure is 54 MW). Net generation was 0.446 GWh in 2024 (a 0.1% capacity factor). Its generators came online between 1977 and 2000.
Grid neighborhood
The closest transmission line found within 10 miles is a 345 kV line owned by MIDAMERICAN ENERGY CO, about 9.2 miles away. Another 9 operating power plants totaling 1,073 MW sit within 25 miles; the largest is GREATER DES MOINES (576 MW, Natural Gas).

Weather peril exposure
INDIANOLA is a 54 MW oil power plant in Warren County, IA, operated by INDIANOLA MUNICIPAL UTILITIES, commissioned in 1977. Warren County carries moderate modeled catastrophe exposure in the FEMA National Risk Index, scoring 2.4 of 5 at the 35th national percentile. Heat wave is the leading peril, rated Relatively Low by FEMA at the 95th percentile.
The Bywatts loss layer is calibrated to solar PV hardware, so it is not applied to an oil plant. The ratings below are the FEMA National Risk Index county hazard ratings for this location.
