Construction is underway on the 50-mile Huntley-Wilmarth 345 kilovolt (kV) transmission line connecting Xcel Energy’s Wilmarth Substation, north of Mankato to ITC’s Huntley Substation, south of Winnebago. Crews are starting work on the northern half of the project in Nicollet and Blue Earth counties. Field agents have already contacted all owners of land that will be affected (view project update).
The project area will be very busy as trucks move in equipment, concrete, transmission structures and other materials. We aim to keep your family, neighbors and our construction crews safe each day. Please use caution when driving near construction zones. Xcel Energy is taking precautions to stay safe and healthy during the COVID-19 pandemic. To allow crews to do their work, and for everyone’s safety, Xcel Energy is requesting that members of the public not approach them in the field. This helps maintain social distance in accordance with various health and safety guidelines.

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. Then click on “search.” Project documents are also available on the Department of Commerce’s website.
Xcel Energy and ITC Midwest representatives will be in touch with landowners as construction work begins. Questions and comments can be directed to the project email and phone number below.
