New Transmission Line Placed in Service in Door County, Wisconsin

A new 7.7-mile transmission line between the Canal Substation in Sturgeon Bay, Wis., and the Dunn Road Substation in the Town of Sevastopol has been placed in service ahead of schedule and under budget by American Transmission Co. (ATC), boosting area reliability of electric supply.

“This transmission line resolves a number of issues in the peninsula,” said David Hovde, ATC local relations consultant. “The system was frequently overloaded, causing low voltages that put reliable service to customers in jeopardy. While some short-term solutions had been applied previously, the new line resolves those problems for the longer term.”

The project, which was approved by the Public Service Commission of Wisconsin in August 2010, came in about $1 million under budget and was placed in service nearly three months ahead of schedule. Final cost of the project is estimated to be $15.8 million.

ATC’s 10-Year Transmission System Assessment calls for an extension of the line from Dunn Road to Egg Harbor as a provisional project for the future. Provisional, or placeholder, projects are those for which studies are not yet complete and may not necessarily represent a preferred alternative.
