Pine Lake to Dunn Ethanol

Dairyland Power Cooperative is rebuilding 20 miles of 69,000-volt (69 kV) transmission line from Xcel Energy's Pine Lake Transmission Substation located on 230th Street in St. Croix County, Wis., to the Dairyland Connorsville Distribution Substation located in Dunn County, Wis. The line is aging and reaching the end of its asset life. The project will involve removing the existing line and rebuilding it into the existing corridor. The project also includes building 12 miles of 69,000-volt (69 kV) transmission line from the Dairyland Connorsville Distribution Substation to the Dairyland Dunn Ethanol Distribution Substation. The purpose of building this new line is to increase local distribution capacity and improve system reliability for the cooperative members in these service territories.
