The Minnesota Public Utilities Commission issued a written order approving the Huntley-Wilmarth transmission line project on August 5. The Commission voted in favor of the proposed purple route (including segments BB and L), with direction to review an alternate route within an approximately two-mile section of the approved route in the Watonwan River area and report back to the Commission within 60 days of the order (View Map. A detailed interactive map is available below).
Xcel Energy officials will be reaching out to affected landowners to obtain survey permission and to acquire the necessary easements for construction of the project over the summer of 2019. Construction is scheduled to begin in the spring of 2020. Read the full press release for more information.
Voltage: 345 kilovolt line
Location: Blue Earth, Fairbault, Nicollet, and Martin Counties, Minnesota
Estimated transmission line length: 20 miles
Targeted in-service: end of 2021
Xcel Energy and ITC Midwest LLC are building the Huntley-Wilmarth project, an approximately 50 mile, 345 kilovolt (kV) transmission line in southern Minnesota. The transmission line will connect Xcel Energy’s Wilmarth Substation, north of Mankato, and ITC’s Huntley Substation, south of Winnebago. Xcel Energy is the project manager and will be leading the construction process. The new line will be built using steel single pole structures in most areas. At some locations two-pole structures may be required.
The Huntley-Wilmarth project will reduce congestion on the transmission grid in southern Minnesota and northern Iowa and deliver low-cost electricity from generation facilities, including wind farms in the area, to consumers. Learn more about why the project is needed.
The Huntley-Wilmarth project required two approvals from the Minnesota Public Utilities Commission (Commission), a certificate of need and a route permit. The Commission determines whether the project is needed and, if it is needed, the route for the project. The Commission determined the project was needed and decided on the appropriate route in June 2019.
All project documents are available on the Commission’s eDockets website. Select “17” in the year field and enter “184” in the number field for the certificate of need or “185” in the number field for the Route Permit.
