Iowa's Annual Wind Generation
This information relates to electricity generated from wind resources. See Iowa's Electric Profile for more information on electric generation from all sources.
| Year | Wind Nameplate Capacity MW(1) |
Wind Electric Generation MWh(2) |

Source Notes: (1) Wind Nameplate Capacity by megawatts (MW) for 2006-2021 based on generator information in Form EIA-860 based on generating units greater than 1 MW, physically located in Iowa, where wind is identified as the prime mover for the applicable year.Â
(2) Wind Energy Generated by megawatt hours (MWh) for 2006-2021 was taken from Form EIA-923. This energy was generated from units greater than 1 MW within the state of Iowa, but some portion of the energy may have been consumed out of state. The data applicable to the years 2006-2021 comes from the final EIA-923 data for each applicable year.Â
(3) This column is calculated by comparing wind-based generation to generation from all fuel sources based on EIA-923.
