Quick answer
The projects came online between 2012 and 2022.[1] One of these projects also has turbines outside Audubon County; the table counts only the turbines in the county.[1] Turbine makers represented in the county: GE Wind (107 turbines), Siemens Gamesa Renewable Energy (24 turbines) and GE Vernova (1 turbine).[1]
Seven of the 139 turbines in the county have no recorded capacity in the database, so the megawatt figures count the rest.[1]
| Project | Online | Turbines in the county | Capacity in the county (MW) |
|---|---|---|---|
| Heartland Divide Wind II | 2022 | 72 | 199.4 |
| Heartland Divide | 2018 | 36 | 86.8 |
| Eclipse | 2012 | 24 | 57.1 |
| Unnamed project (Audubon County) | 2018 | 7 | Not recorded |

Turbines at the oldest project in the county have been in place since 2012.[1] Wind power leases generally have terms of 20 to 40 years, often with an option to extend, while a typical utility-scale wind power project has a useful life of 20 years.[2] The newest project here came online in 2022.[1] In royalty arrangements, the developer pays the landowner a percentage of the revenue received from the electricity produced by the turbines.[2] Minimum payments serve as a floor so landowners receive some revenue even when maintenance outages or lower winds cut production in a given year.[2]
The five states with the most electricity generation from wind in 2025 were Texas, Iowa, Oklahoma, Kansas and Illinois.[3]
What Buckhead buys depends on the deal, and Buckhead tells the seller up front which interest it is offering to buy — for example, the payments for the rest of the current lease term, a term easement, or a longer-term interest. A wind lease rents land for a term of years, and wind power leases generally have terms of 20 to 40 years, often with an option for extending the lease.[2] Under a wind lease, the landowner typically keeps the right to continue to grow crops, raise cattle or otherwise use the land outside the project.[2]

Audubon County, Iowa has four operating wind projects with 139 turbines and 343.3 MW of recorded capacity in the county, according to the U.S. Wind Turbine Database (version 9.1, released September 28, 2026).[1] Seven of the 139 turbines in the county have no recorded capacity in the database, so the megawatt figures count the rest.[1]
The projects are Heartland Divide Wind II (2022, 199.4 MW), Heartland Divide (2018, 86.8 MW), Eclipse (2012, 57.1 MW) and Unnamed project (Audubon County) (2018).[1]

Of the projects with a recorded year, three came online in the 2010s and one in the 2020s.[1] Wind power leases generally have terms of 20 to 40 years, often with an option to extend, while a typical utility-scale wind power project has a useful life of 20 years.[2]
Nearby Iowa counties with wind projects include Guthrie County (149.9 MW), Pottawattamie County (165.2 MW), Carroll County (215.3 MW), Cass County (422.4 MW) and Adair County (1,130.2 MW).[1]
