About the project: In 2022, MISO identified a long-range transmission plan project that upgrades approximately 150 miles of transmission lines between southern Minnesota and Blair, Wis., to strengthen the regional electric grid. In Wisconsin, the project includes upgrading the existing line to 345 kV along an existing corridor between Alma and Blair, Wis.  Therefore, Dairyland's Alma-Blair Transmission Project includes building a new 345 kV transmission line following the existing line corridor between the Alma Substation near the Mississippi River and the Tremval Substation near Blair, Wis. 

Dairyland is proposing two route options: a Northern Route and a Southern Route. The Northern Route is approximately 44 miles long, while the Southern Route is approximately 33 miles long. The project plans to use existing corridors to the extent possible. The Public Utilities Commission of Wisconsin (PSCW) will choose the final route.
