Solar Energy Land Leasing in Greene County, Iowa

How the county got here: a 2022 moratorium and ordinance rewrite

In 2021, National Grid Renewables proposed a large utility-scale solar project south of Grand Junction, and residents packed county hearings with concerns about the scale, the leasing terms being offered to neighboring landowners, and the lack of a clear county process for permitting a project of this size. The Board of Supervisors responded in March 2022 by adopting a temporary moratorium on new utility-scale solar permits, giving the county time to draft zoning-ordinance provisions specific to large solar installations rather than trying to fit the project into rules written for other land uses.

That drafting process ran through most of 2022, with supervisors debating specific provisions -- including setback distances -- before adopting the amended ordinance. The practical lesson for a landowner: Greene County's solar-specific zoning rules are recent, were shaped directly by public pushback on this project, and are worth reading in their current form rather than assuming they mirror another county's approach.

Grand Junction Solar: permitted in 2023, ownership changed, timeline still open

The Greene County Board of Adjustment granted a conditional use permit in July 2023 for Grand Junction Solar -- an up to 100 MW solar array covering roughly 950 acres, tying into the Karma substation on Highway 144 south of Grand Junction. The arrangement includes an estimated $123,000 a year in replacement tax revenue to local taxing bodies (compensating for land coming out of agricultural production tax rates) plus up to $20,000 a year pledged to a community charitable fund. The Iowa Utilities Board separately authorized the project in Docket No. GCU-2022-0001; the original application paired the solar array with a 50 MW battery energy storage system, though later reporting indicates that battery component was dropped during the permitting process.

Alliant Energy has since acquired the project from National Grid Renewables. As of the most recent local coverage found in this research pass (April 2024), county supervisors were told there was still no firm construction start date -- meaning a project that cleared local and state permitting more than three years ago may not yet be built, or may have moved forward since without matching news coverage. Confirm current construction status, exact project footprint, and any change in scope directly with the county or with Alliant Energy before relying on any timeline reported here.

What to verify before treating a lease or nearby project as a value driver

• Current construction status of Grand Junction Solar and whether its footprint or capacity has changed since the 2023 conditional use permit -- directly with Greene County Planning & Zoning ((515) 386-5669), which staffs the Board of Adjustment process.
• Whether a specific parcel sits within the Grand Junction Solar project footprint (the area south of Grand Junction tying into the Karma substation), within an adjacent easement corridor, or merely nearby -- proximity alone does not mean a parcel carries or is affected by a lease.
• The county's current utility-scale solar zoning provisions (added after the 2022 moratorium) for setback and permitting standards that would apply to any new project, not just Grand Junction Solar.
• For a parcel already under an executed lease with Grand Junction Solar or a future solar/battery-storage developer, the payment structure (signing bonus versus per-acre or per-megawatt royalty) and whether payments are contingent on the project reaching commercial operation.
• Whether the replacement-tax arrangement negotiated for Grand Junction Solar (roughly $123,000/year plus a community charitable fund) reflects current county practice or was project-specific, before assuming similar terms would apply to a different proposal.
