Wind and Solar Leasing in Sac County, Iowa

Two operating wind farms, two different owners, two different eras

The Intrepid Wind Farm, owned and operated by MidAmerican Energy, has been operating in Sac and Buena Vista Counties since 2004 -- one of the earlier utility-scale wind installations in this part of Iowa. It comprises 107 wind turbines with a combined nameplate capacity of 160.5 MW. Because it spans two counties, a specific parcel's participation and any associated lease terms depend on exactly where the turbine or associated infrastructure (access roads, collector lines, substations) sits relative to the Sac/Buena Vista county line -- worth confirming directly with MidAmerican or the landowner's own lease documentation rather than assuming county-wide uniformity.

Alliant Energy's Richland Wind Farm is a newer, larger single project: construction began in July 2019, and the 130 MW project was completed and operational by October 1, 2020, part of a broader Alliant Energy push that reached 1,000 MW (1 GW) of wind capacity in Iowa several months ahead of schedule and within budget. Alliant's Richland project is reported to provide power to roughly 430,000 Iowa homes as part of the company's broader Iowa wind portfolio (the specific 430,000-home figure describes Alliant's wind fleet contribution generally rather than Richland's output in isolation, so treat it as context rather than a precise per-farm figure).

What two decades of wind development in the same county tells a landowner

Unlike a county with no wind history at all, Sac County gives you two decades of real, observable outcomes to research before signing anything: how MidAmerican and Alliant have each handled construction, access-road maintenance, decommissioning planning, and neighbor relations here specifically. If you're considering a new lease offer -- from either of these companies or a different developer -- ask current Intrepid or Richland-area landowners about their actual experience: payment timing and structure, how access roads and drainage were handled during construction, and how the company has responded to any operational issues since. That kind of real, local reference-checking is more valuable than anything in a general national guide.

Because two different companies operate in the same county under (potentially) two different generations of Sac County's zoning ordinance provisions for wind energy systems, confirm with the Sac County Planning and Zoning Department which specific ordinance provisions and setback requirements applied to each project's siting, and whether the ordinance has been updated since either project was approved. A newer project proposed today would be evaluated under the current ordinance, which may differ from the rules that governed Intrepid in the early 2000s or Richland in 2019.

What to verify before signing a lease or buying near a turbine

1. Get the current Sac County zoning ordinance provisions governing wind energy systems (setbacks, permitted districts, decommissioning requirements) directly from the Planning and Zoning Department -- this page does not reproduce that ordinance text verbatim.
2. If your parcel is near the Sac/Buena Vista county line and within the Intrepid Wind Farm footprint, confirm with MidaAmerican and the county which jurisdiction's rules apply to any nearby infrastructure.
3. Ask current landowners within either wind farm's footprint about their real experience with payment structure, access-road maintenance, and decommissioning-bond terms before evaluating a new lease offer.
4. Have any new lease or easement offer reviewed by an attorney experienced in Iowa wind-energy leases -- lease terms are separate from, and not resolved by, the county's zoning ordinance.
5. Confirm current setback distances from your specific property line and any occupied residence before assuming a turbine could be sited on or near a given parcel.
