ITC Midwest and Xcel Energy are proposing to build a 40-50 mile 345 kilovolt (kV) transmission line that would connect ITC Midwest's Huntley Substation, south of Winnebago, and Xcel Energy's Wilmarth Substation, north of Mankato. The Huntley-Wilmarth project will increase access to low-cost electricity and help reduce congestion on the transmission grid.
