Wind and Solar Energy Leasing in Knox County, Indiana

2022: wind is banned countywide, solar moves forward case-by-case

Knox County's current wind-and-solar landscape traces back to August 2022, when the Board of Commissioners passed a resolution banning large wind-energy projects -- defined as anything generating more than 1 megawatt -- countywide, while agreeing to review large-scale solar projects (50 megawatts and larger) on a case-by-case basis instead. Commissioner Teresa Bemiller's own explanation at the time was straightforward: county leaders believed residents didn't want to see wind turbines in Knox County, even though wind hadn't actually come up as a live proposal. Solar, by contrast, was treated as more acceptable in principle, provided each project went through individual review.

That case-by-case process produced real, sizable projects. Ratts 2, a roughly 1,200-acre, $128 million solar development, won Area Plan Commission approval on a 7-to-3 vote despite resident concerns, with an estimated $16 million in county tax revenue and $2.5 million in economic-development payments to the county projected over a six-year period. Separately, the Area Plan Commission unanimously approved a development plan from Orion Renewables covering Harrison and Johnson townships after extensive public comment. If you own land near either of these project footprints, or you're evaluating a lease offer citing either as a comparable, those approved terms are a useful, sourced reference point.

2025: commissioners pull back, restricting new solar to fewer townships

The case-by-case approach didn't settle the underlying conflict. In February 2025, commissioners passed a further resolution, proposed by Commissioner Barry Lester, restricting new utility-scale solar development to only a minority of the county's townships going forward, with remaining eligible areas still reviewed case-by-case. That vote followed a public hearing at which roughly 102 residents turned out, and township trustees countywide reaffirmed their opposition to further large-scale solar development -- a genuinely significant local turnout for a rural Indiana county commissioners' meeting.

This research pass could not reliably confirm the exact number or names of townships covered by that February 2025 restriction; some search-indexed reporting cited figures and township names that don't match Knox County's own well-documented ten-township structure, and are treated here as unverified rather than repeated as fact. What is confirmed is the substance of the restriction: after February 2025, new utility-scale solar proposals in Knox County faced a materially narrower path than they had in the 2022-2024 case-by-case era.

2026: the county rewrites its rules again -- setbacks, screening, and a new advisory committee

Rather than holding the 2025 restriction as a final answer, Knox County commissioners kept working the issue. In April 2026, following a meeting that drew more than 70 residents to Vincennes City Hall, commissioners adopted updated solar-ordinance provisions: the required setback between a solar facility and a neighboring home increased from 200 feet to 300 feet, new landscaping and screening requirements now call for a combination of opaque fencing and vegetative buffers to limit visibility and glare, and a well-water-testing requirement was added, along with a cap on the total acreage the county will allow for solar development. Some residents at that meeting argued even 300 feet wasn't enough, pushing for setbacks in the 650-to-1,000-foot range -- a sign the debate over adequate distance is still unresolved even after the update.

The county also formed a 12-member advisory committee to keep revising the solar ordinance and to begin developing entirely new rules for data centers, wind energy, and battery energy storage systems -- meaning Knox County's renewable-energy rulebook should be treated as a genuinely moving target, not a settled ordinance, for the foreseeable future.

What this means if you own land or are considering a lease

Given how many times Knox County's rules have changed since 2022 -- and given that a formal advisory committee is actively working on the next round of updates as of this writing -- do not rely on any secondhand summary of the county's wind or solar rules, including this page, for a specific parcel or lease decision. Get the current adopted ordinance text directly from the Knox County Area Plan Commission, confirm whether your parcel's township is currently eligible for new solar development under whatever rule is in effect at the time you're reading this, and have any lease offer reviewed by an attorney experienced in renewable-energy leases, since the terms that were market-standard when Ratts 2 or the Orion project were signed may not reflect what a developer is offering (or what the county will actually permit) today.
