Rochester to Wabaco 161 kV Circuit

Dairyland Power Cooperative plans to rebuild 13.2 miles of 161 kV transmission lines between its Rochester Transmission Substation located on 50th Ave SE in Olmsted County, Minn., to the existing Dairyland Wabaco Transmission Substation located on County Rd 4 in Wabasha County, Minn. The construction project will involve removing the existing two-pole wooden structures and rebuilding a new 161kV line with steel monopole structures and new conductor wires along an existing Dairyland transmission corridor. In addition to the line work, there will also be equipment upgrades made at both the Rochester and Wabaco Transmission Substations. The purpose of this work is to upgrade the transmission line's reliability in the area and allow for improved transmission of locally generated wind and solar electricity.
