New London 69-kV transmission line reroute

Great River Energy, wholesale electric supplier to Kandiyohi Power Cooperative, is proposing a 4-mile relocation of an overhead 69-kV (69,000 volt) transmission line. The project will replace 7 miles of aging transmission line built in 1948 and supply a more reliable looped electric service to Kandiyohi Power Cooperative’s Prairie Woods Substation located on County Road 40 in New London. This project is an extension of a required transmission line relocation to accommodate the Minnesota Hwy 23 four-lane expansion.

Replacing and relocating the existing transmission line is a priority project for Great River Energy. The current line has limited emergency and maintenance access including significant elevation changes, narrow strips of land, wetlands and a river crossing. This relocation will implement modern construction and accessibility standards and lead to improved reliability for the area.

The proposed relocation begins west of the intersection of MN Highway 23 and 199th Avenue NE. Initially, the route runs along the west side of MN Highway 23 then crossing to the east. At MN Highway 9 the route turns north to Kandiyohi County Road 40 then west to the Prairie Woods Substation.

Transmission line construction will generally use single wood or steel poles 70 to 80 feet above ground, placed 350 to 400 feet apart. Specialty poles may be required. Directional changes or angles require guy wires and anchors to stabilize poles.
