Construction complete for Port Washington-Saukville Rebuild Project

Posted on January 7, 2022

Transmission modifications strengthen regional electric reliability, operating flexibility

 

PEWAUKEE, Wis. – ATC has completed construction of the Port Washington-Saukville Rebuild Project. This project included a 4.8-mile, 138,000-volt transmission line rebuild, along with modifications at the Port Washington Substation in Port Washington, Wis., and Saukville Substation in Saukville, Wis.

Initially identified in ATC’s 10-Year Assessment in 2009, this $25 million infrastructure investment strengthens electric transmission reliability in the southeast Wisconsin area and improves operating flexibility under certain system conditions. The project was officially placed into service Dec. 18, 2021.

The prior H-frame structures were replaced with 41 galvanized steel single-pole structures and new wires, transitioning the line from a single circuit to a double circuit. The replacement process took place in phases. ATC’s contractor, M.J. Electric, began construction in spring 2020 to coincide with system and operational maintenance activities. 

“In addition to new wires, we also installed fiber optic wire, which will provide high-speed data to our system operations center,” said Jon Meiers, senior project manager.

Substation work at the Port Washington Substation included the addition of a control house and perimeter fencing. A portion of the Saukville Substation also was upgraded, and line positions were changed.

Restoration along the right-of-way will initiate in the coming weeks and is expected to be complete this spring.
