Turbines at the oldest project in the county have been in place since 2017.[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 2018.[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]
