Wind and Solar Land Leasing in Jefferson County, Wisconsin

Who actually decides: the state PSC, not Jefferson County, for the largest projects

Wisconsin law gives the Public Service Commission of Wisconsin (PSC) siting authority over large electric generation facilities, including utility-scale solar projects above certain size thresholds -- meaning a project of the scale seen in Jefferson County goes through a state Certificate of Public Convenience and Necessity (CPCN) process rather than an ordinary county rezoning hearing. Jefferson County Planning & Zoning still plays a real role (weighing in during the state process, negotiating local road-use agreements and decommissioning terms, and administering its own zoning for the conditional-use and prime-soil provisions described below), but the county generally cannot deny a state-sited project outright the way it could deny an ordinary rezoning request.

That distinction matters most if you're a neighboring landowner opposed to a project: a county hearing is not necessarily where the ultimate siting decision gets made for the largest projects, even though it's often the most visible local venue for public comment.

What's actually built, approved, or proposed in Jefferson County

Alliant Energy's Crawfish River Solar project -- roughly 75 megawatts across about 500 acres near the City of Jefferson -- has been in commercial service since 2024. Ranger Power's Badger State Solar project -- 149 megawatts across roughly 1,200 acres in the Towns of Oakland and Jefferson, about 25 miles southeast of Madison -- won unanimous PSC approval, with power sold to Dairyland Power Cooperative and construction expected to power the equivalent of more than 20,000 homes. Invenergy's proposed Sinnissippi Solar Energy Center -- roughly 100 megawatts, with development rights secured across nearly 2,000 acres spanning the Towns of Concord, Ixonia, Watertown, and Farmington -- was in PSC review as of this research pass, with construction targeted for 2027 and operation for 2028.

This research pass did not find a documented utility-scale wind project specifically sited in Jefferson County (as distinct from Columbia County's proposed Alliant Energy wind farm, covered on this project's Columbia County page) -- the county's current utility-scale renewable activity is solar-specific. Project scope, ownership, and approval status can all change as PSC and local proceedings continue; confirm current status directly with the PSC and Jefferson County Planning & Zoning before relying on a specific acreage, megawatt, or timeline figure here.

The county's new Solar Energy Systems ordinance: a 25% prime-soil cap

In around March 2026, the Jefferson County Board adopted a Solar Energy Systems zoning ordinance amendment after a roughly two-year process that included extended public debate (the board sent an earlier draft back to committee before final adoption). The amendment creates a dedicated section of the county zoning code treating solar as a conditional use on agricultural land, and its central substantive rule is a cap: both small and large solar energy systems must limit use of prime agricultural soil to 25% or less of the total project area, with any excess allowed only case-by-case, subject to Planning and Zoning Committee review and approval and required mitigation. The ordinance also requires site and soil assessments identifying soil classification for the project area, and imposes reporting requirements -- for example, notice to the county within 10 days of any change in ownership of a large system, and an as-built facility description and map filed within 90 days of a large system beginning operation.

For a landowner in agricultural use considering a solar lease, the practical implication is that a project developer's proposed layout on your land (and on any adjacent parcels bundled into the same project) has to work within that 25% prime-soil ceiling across the whole project area -- which can affect how much of a given farm a developer actually wants to lease, and which specific fields within it, depending on soil classification.

The money: what the state, county, and towns get, versus what you get as a landowner

It's worth being explicit about a distinction that's easy to blur: Wisconsin's state utility-aid revenue-sharing law requires the owners of solar facilities over 50 megawatts to pay annually into a fund shared with the local governments hosting the project -- under the formula in place, that's $2,333 per megawatt per year to the host county and $1,667 per megawatt per year to the host town(s), a combined $4,000 per megawatt per year. For Badger State Solar's 149 megawatts, that works out to roughly $348,000 a year for Jefferson County and roughly $125,000 and $123,000 a year respectively for the Towns of Jefferson and Oakland, split by acreage or agreement between hosting towns.

That state utility-aid payment goes to local government, not to you as a leasing landowner -- it's a separate revenue stream from whatever lease payment a developer negotiates directly with you for the land itself. If you're evaluating a lease offer, don't confuse the two, and don't assume the per-megawatt local-government figure tells you anything about a fair per-acre lease rate for your own land; those are two different negotiations with two different counterparties.

What to actually do

1. If you've gotten a solar lease offer, get independent legal review of the lease term length, decommissioning bond/obligations, payment escalation clauses, and how the 25%-prime-soil ordinance provision might affect which of your fields actually get used -- these agreements often run 20-30+ years and are genuinely negotiable on a first offer.
2. If you're buying land near an active or proposed project rather than inside its footprint, ask Jefferson County Planning & Zoning directly what has been filed with the PSC and the county for that specific area, since a project's land-control footprint (which developers typically secure well beyond the actual panel layout) can extend further than visible construction suggests.
3. Confirm with the county whether a specific parcel's soil is classified as "prime agricultural" under the new ordinance, since that classification is what actually drives the 25% cap calculation for any project including that land.
4. Don't assume a county-level revenue-sharing estimate (like Badger State Solar's roughly $348,000/year to the county) has any bearing on what a lease should pay you personally -- confirm current per-acre solar lease rates in the area independently, ideally through a real-estate or agricultural-law professional experienced in Wisconsin renewable leases.
5. If a project's footprint is proposed near, but not on, your land, ask specifically about setback, visual-screening, and decommissioning requirements the county negotiated or the new ordinance imposes, since these vary by project and by ordinance provision.
