Wind and Solar Energy Leasing in Stephenson County, Illinois

What's already built: EcoGrove Wind Farm and High Point Solar Farm

ACCIONA Energía's EcoGrove Wind Farm has generated power in Stephenson County for more than a decade, with a total capacity of 100.5 megawatts. Rather than developing a separate site, ACCIONA later built the High Point Solar Farm -- an approximately 127-megawatt facility using solar-tracking technology, paired with agrivoltaic land-stewardship practices -- directly within the existing wind farm's footprint. The result is one of the more established hybrid wind-and-solar sites in northern Illinois, with both wind and solar infrastructure sharing the same general area near Lena.

If you're buying farmland in this part of Stephenson County -- particularly in or near West Point Township -- pull the parcel's recorded documents at the Stephenson County Recorder's office and ask directly whether an EcoGrove or High Point lease, easement, or collector-line agreement is recorded against it, since a long-running site like this one can have multiple overlapping agreements layered over the years.

A much larger proposal: the Blue Violet Energy Facility

Liberty Power, working with Nexamp on the local permitting process, has proposed the Blue Violet Energy Facility on land south of Lena spanning Kent and Erin Townships. As presented to the county, the project combines a 50-megawatt solar plant on roughly 254 acres, a 40 MW/4-hour battery energy storage system, a substation, and a 174-megawatt wind facility of up to 29 turbines -- a considerably larger combined footprint than the existing EcoGrove/High Point site. At a November 2022 hearing, the Stephenson County Zoning Board of Appeals recommended the special-use application be granted, on the condition that one parcel north of Illinois Route 20 be removed from the project area; the county's own posted minutes estimated roughly $2.47 million in wind-related tax revenue and $330,618 in solar-related tax revenue if the project is built as proposed.

A Zoning Board recommendation is not the same as a finished, operating project -- treat the timeline, exact turbine layout, and final terms as subject to change until you've confirmed current status directly with the county. If you're evaluating land in or near Kent or Erin Townships, ask the Department of Building & Zoning whether the project has since received final county board approval and whether construction has actually begun.

A parallel wave of smaller community-solar projects

Separately from the wind-and-battery-storage story above, Stephenson County has also seen a run of smaller community-solar development. Reporting from Stateline Solar describes a county-wide target of roughly 180 megawatts of community solar capacity, including a 100-megawatt project on about 600 acres inside the existing EcoGrove Wind Farm footprint in West Point Township, plus the much smaller (2.86 MW) Stephenson S1 community solar project near Freeport developed by Radiance Solar and SolAmerica Energy. Community-solar projects typically involve smaller individual parcels than utility-scale wind or solar farms, but the same due-diligence question applies: check whether a specific parcel is under lease before assuming it's unencumbered.

The state law limiting what Stephenson County can require

Illinois counties don't have unlimited authority to write their own wind and solar rules. Public Act 102-1123, signed January 27, 2023, amended 55 ILCS 5/5-12020 of the Counties Code to set statewide siting standards -- covering setbacks, turbine and panel heights, decommissioning, and agricultural-land treatment -- that a county's own ordinance cannot exceed in restrictiveness, and it bars counties from imposing outright moratoriums on wind or solar development. Stephenson County's own zoning ordinance, including whatever specific wind/solar/BESS provisions apply to a pending application like Blue Violet Energy, operates within that statewide ceiling.

If you've been offered a lease, or are buying land already under one

If you're the landowner being approached about a new lease: the county's zoning ordinance (bounded by the PA 102-1123 statewide ceiling) sets the regulatory floor on setbacks and decommissioning, not the lease's financial terms. Payment structure, term length and renewal options, what portion of your land the easement actually covers (turbine/panel footprint only, versus also access roads and collector-line corridors), and who's responsible for decommissioning costs if the developer becomes insolvent are all matters of private contract worth review by an attorney experienced in Illinois wind and solar leases.

If you're buying land already subject to a recorded EcoGrove, High Point, or (eventually) Blue Violet Energy lease or easement, pull the actual recorded document from the Stephenson County Recorder rather than relying on a listing summary. Confirm what portion of the parcel is actually restricted, whether the agreement transfers automatically to you as the new owner, what ongoing payments (if any) you'd be entitled to, and whether decommissioning security is on file with the county for that specific project.
