Sioux County approves Conditional Use Permit for 300-MW NextEra wind project after contentious hearings

Sioux County commissioners approved a Conditional Use Permit (CUP) for the Sioux County Wind Farm, LLC project — a proposed 300‑megawatt utility‑scale wind energy conversion system — at a May 23, 2024 special meeting in Harrison.

The motion to approve the permit was made by Commissioner J.W. Geiser and seconded by Commissioner Josh Skavdahl. On roll call vote Geiser, yes; Hal Downer, no; Skavdahl, yes, and the motion carried. County Attorney and planning staff had earlier reviewed the application and the Sioux County Planning Commission had recommended approval with conditions.

David Levy, attorney for the applicant, and Austin Paxson, project manager for NextEra Energy, presented project details including road‑use plans, decommissioning requirements, bonding and projected tax revenues. Levy told the board that the application includes a road‑use and decommissioning plan and that bonding requirements are in the permitting package. “NextEra Energy is a Fortune 500 company, so they’re not going away,” Levy said, arguing for the permit’s legal and factual basis.

Public commenters at earlier hearings and during the April 1 and May 23 sessions raised a range of concerns. Residents and landowners questioned the adequacy and timing of wildlife and eagle surveys, potential impacts on migratory birds, road damage from construction traffic, the adequacy of bonding and potential effects on property values. One attendee submitted materials alleging health impacts and effects on livestock and children; another submitted minutes from a neighboring county’s commission meeting as a model for permit conditions.

NextEra and its consultants said environmental and eagle surveys are underway or will be completed as required, that post‑construction monitoring is part of standard practice, and that road agreements and bonds will be finalized before construction. Counsel also pointed to studies they said showed no statistically significant property‑value impacts in some comparative reviews.

The board’s approval incorporates planning commission conditions; county staff noted that road‑use agreements, decommissioning bonds and other permit conditions are expected to be finalized before any construction activity begins. The board tabled action after the April hearing to allow more review and returned to decide on May 23.

Following the vote, commissioners and county staff said additional project conditions and road‑use agreements will be part of later administrative reviews. The planning commission and county clerk’s office hold the official permit documents and any subsequent agreements and monitoring reports will be filed with the county.

Next procedural step: county staff will track compliance with conditions in the CUP and any required road‑use and decommissioning agreements prior to project construction.
