Quick answer
The projects came online between 2003 and 2008.[1] One of these projects also has turbines outside Harper County; the table counts only the turbines in the county.[1] Turbine makers represented in the county: GE Wind (107 turbines) and Suzlon (54 turbines).[1]
| Project | Online | Turbines in the county | Capacity in the county (MW) |

Turbines at the oldest project in the county have been in place since 2003.[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 2008.[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]
Oklahoma makes the owner of a wind energy facility responsible, at its expense, for decommissioning it, including removing turbines, cabling and foundations to 30 inches below grade.[3]
In Oklahoma, a landowner paid on the amount of electricity produced must receive, by a statutory deadline after each payment, a statement that explains the basis for the payment and a means of confirming it.[3]
Oklahoma landowners who are paid on the amount of electricity produced and who have allowed a wind turbine foundation on their property may also inspect the operator's records, no more than once per calendar year, to confirm the accuracy of payments made within the past 24 months.[3]
In Oklahoma, the lessee of a wind or solar energy agreement may not unreasonably interfere with the mineral owner's right to make reasonable use of the surface to produce minerals.[4]
The five states with the most electricity generation from wind in 2025 were Texas, Iowa, Oklahoma, Kansas and Illinois.[5]
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]
