Wind and Solar Land Leasing in Adair County, Missouri

High Prairie: a real, large-scale wind lease footprint

The High Prairie Renewable Energy Center spans Adair and Schuyler Counties, with 175 turbines and a combined nameplate capacity of 400 MW. It was developed by TG Prairie, LLC (an affiliate of Terra-Gen) before Ameren Missouri acquired the project in December 2020, and it secured wind-lease option rights across more than 70,000 acres from over 200 landowners in the two counties before construction. Each turbine sits on private property, with the host landowner compensated under an individual lease -- this is the general pattern for utility-scale wind in Missouri, and it means neighboring, non-host landowners inside the project footprint typically see turbines, access roads, and collector lines nearby without receiving turbine-host payments themselves, so it’s worth clarifying which category a specific parcel falls into before assuming any income applies.

The Adair County Commission granted the project assent to cross public roads and highways as part of construction -- a county-level approval tied specifically to road use, not a general zoning or special-use permit, since Adair County has no zoning ordinance to grant one under. If you are evaluating raw land near the High Prairie footprint specifically because of renewable-energy potential, the road-crossing and easement documents recorded against a project-area parcel (available through the Adair County Recorder) are a more reliable source of what was actually agreed to than general project descriptions.

The 2024 turbine collapses: a real, documented reliability issue

High Prairie experienced three separate turbine collapses in 2024 -- April 29, August 25, and November 1 -- all tied to wind-turbine blade failures that caused a rotor imbalance severe enough to bring the turbine down. Vestas, the turbine manufacturer, investigated, and Ameren undertook inspections and blade replacements across the site. As of early-to-mid 2025 reporting, the large majority of the 175 turbines remained shut down pending inspection results, with only a small number (roughly a dozen to fifteen) confirmed running, and no fully confirmed timeline for restoring the full site to operation.

For a landowner who is already a turbine host under an executed lease, a period of turbine downtime does not necessarily void the lease -- most utility-scale wind leases pay a minimum or guaranteed payment structure that isn’t solely tied to real-time generation, but you should read your specific lease’s payment terms (or, if buying land already under an existing lease, request the lease itself) rather than assume either full payment continuity or a full stoppage. For anyone evaluating a new lease offer anywhere in this corridor, the collapses are a concrete, documented example of why decommissioning obligations, insurance/liability provisions, and turbine-model track record are worth asking about directly rather than treating a renewable-energy lease as risk-free income.

Morris Solar: Missouri’s largest solar project, still new

The Morris Solar Project, developed by AES, is a roughly $400 million, 250 MW facility covering about 1,100 acres in southern Adair County, near Missouri Highway 3 and extending toward the Kirksville Regional Airport. It became operational in 2025 and has been reported locally and by AES as Missouri’s largest solar farm. Because the project is newly operational, there is limited multi-year track record yet on performance, maintenance disruptions, or community impact compared with a project like High Prairie that has been running since the late 2010s -- treat performance claims about Morris Solar as early-stage rather than long-proven.

AES has also publicized a panel-recycling partnership (SolarCycle) tied to this project, which is a genuinely useful data point if you are evaluating end-of-life/decommissioning obligations for a solar lease specifically -- ask a developer directly whether panel recycling or removal costs at decommissioning fall to the landowner, the developer, or a bonded third party, since that allocation varies by contract and matters much more at year 25-30 of a lease than it does today.

No zoning to clear -- but real county and state steps still apply

Because Adair County has not adopted county-wide zoning, a wind or solar project here does not go through a special-use-permit or rezoning process the way it would in a fully zoned Midwest county. That does not mean there is no process at all: road-crossing and right-of-way assent from the County Commission (as granted for High Prairie), any required OWTS/septic permitting for on-site facility buildings, and state- and federal-level approvals (utility interconnection, environmental review tied to any transmission buildout) still apply independent of county zoning. For a landowner considering a lease, the County Commission remains the reference point for any county-level land-use question specific to a parcel, precisely because there is no zoning code or planning department to consult instead.

What to verify before treating a lease -- new or existing -- as bankable

• Whether the lease payment is a fixed/guaranteed minimum, a per-turbine or per-acre royalty tied to actual generation, or some blend -- and how a documented multi-month outage like High Prairie’s 2024 collapses would affect that specific formula.
• Decommissioning and removal obligations at end of lease term, including who bears the cost for turbine, panel, and foundation removal, and whether a bond or financial assurance is required.
• Whether you are evaluating a turbine-host parcel (direct lease payment) or a non-host parcel within the project footprint that sees infrastructure but no lease income -- these are very different positions.
• Recorded easements, road-crossing agreements, and collector-line rights-of-way against the specific parcel, available through the Adair County Recorder, rather than relying on general project descriptions.
• Current turbine operational status if proximity to an operating (versus partially idle) turbine matters to your use of the land.
