Prairie du Sac-Portage Electric Reliability Project
PROJECT STATUS: Completed and in service
American Transmission Co. has plans to rebuild a 25-mile, 69,000-volt transmission line from Portage to Prairie du Sac, Wis.
The project will involve stringing new wires and replacing aging transmission poles with new steel poles.
Rebuilding the line will help ensure electric reliability in the area by relieving potential transmission system constraints.
This approximately $51 million project received regulatory approval along with a proposal to rebuild a 20-mile, 69,000-volt transmission line from the Wautoma Substation in Wautoma to the Montello Substation in Montello, Wis.
