Wisconsin corridors for Hampton-Rochester-La Crosse 345-kV transmission line project

The proposed Hampton-Rochester-La Crosse line is part of a major upgrade of the region’s transmission system to meet customers’ growing demand for electricity and to increase access to new generation, including renewable energy. The CapX2020 utilities are evaluating a number of possible route options in Minnesota and Wisconsin for the proposed line including several new route options in Wisconsin. The route options are highlighted on the map and include potential upgrades of existing lines between Alma and Blair, Arcadia and Galesville, and Blair and Holmen. A new corridor is also being studied south of Galesville along Highway 53. Many route options are currently being studied, but the Public Service Commission of Wisconsin (PSCW) will only approve one route at the end of its permitting process.

Areas outside of these route options should not be considered exempt from further analysis. Please continue to be involved with this important project.
