American Transmission Co. (ATC) has filed an application with the Public Service Commission of Wisconsin to build a new 8- or 9-mi power line from Sturgeon Bay to a substation along Dunn Road in the Town of Sevastopol.

“The new line is needed to address electric transmission reliability issues in the Sturgeon Bay, Egg Harbor and Sister Bay areas,” explains David Hovde, senior local relations representative for ATC. “The two 69-kV lines that currently serve Door County leave the area vulnerable to outages when either line is out of service for repair or maintenance.”

ATC plans to add a new, 138-kV circuit to reinforce the system. Two route alternatives are described in the regulatory application. The proposed route follows the existing transmission line corridor from the Canal Substation southeast of downtown Sturgeon Bay to the Dunn Road Substation. The alternate route also follows the existing line for about 5 mi, then follows a new corridor to the Dunn Road Substation. ATC is required by state law to submit two route alternatives; the PSCW selects the route if the project is approved.
