Sweetland Wind Project

​Sweetland Wind, LLC (Sweetland) proposes to construct the Sweetland Wind Project (Project) in Hand County, South Dakota.  The Project would generate up to 200 mega-watts and would  interconnect to WAPA's existing Fort Thompson-Huron 230kV transmission line.

If there is available transmission capacity on the federal transmission system, WAPA provides open access to transmission services so that energy producers can transmit power to their customers.  Any entity requesting transmission services must submit an application for interconnection.  For more information about the interconnection process, visit WAPA's website here​.  The federal interconnection process is separate​ from any State, County, or local permitting and approvals that may be required.    

​The proposed interconnection of the Project to WAPA's transmission​ system is a Federal action under NEPA.  As a result, an Environmental Assessment (EA) was prepared to evaluate the environmental effects of the Project.  WAPA found there were no significant environmental impacts and selected the Proposed Action Alternative for implementation, as documented in the Finding of No Significant Impact (FONSI), linked below.  ​

Following the completion of the EA and FONSI, Sweetland proposed to redesign a portion of the approximately 7-mile-long, 230-kilovolt (kV) transmission line (gen-tie) outside of the area previously analyzed in the 2021 EA. ​​ As a result, WAPA has prepared a prepared a ​​Supplemental Environmental Assessment (SEA) to analyze potential impacts of the newly proposed gen-tie line route which were not previously analyzed in the 2021 EA.  The redesigned segment would parallel the north side of WAPA’s existing Fort Thompson to Huron 230-kV line and across a 0.6-mile portion of the U.S. Fish and Wildlife Service (USFWS) Hand County Waterfowl Production Area (referred to hereinafter as the Grassland Easement).​  The USFWS served as a Cooperating Agency in the preparation of the SEA, due to their jurisdiction by law regarding the Grassland Easement.


Multiple opportunities for public involvement were offered.  Public involvement began with a scoping meeting on August 7, 2018, in Miller, South Dakota.  The scoping meeting was advertised through newspaper announcements, a project website, and individual letters to agencies, tribes, and residents within and near the Project area.  The public scoping meeting documentation is included in Appendix P of the EA.  WAPA circulated the draft EA for public review and comment on November 18, 2019.  Comments on the draft EA were accepted through December 20, 2019.  Comments and responses are included in Appendix Q of the EA.

WAPA and the USFWS are now requesting your review and comment on the draft SEA, which is available for download below.  Comments may be submitted in the following ways:
