Saukville – St. Lawrence rebuild is complete
Newly energized electric transmission line moves power; boosts reliability
ATC’s Saukville-St. Lawrence line supports output from Port Washington Generating Station
PEWAUKEE, WIS. – An existing 138-kilovolt electric transmission line between the Saukville Substation and the St. Lawrence Substation (located northeast of Slinger in the town of Hartford) was returned to service by American Transmission Co. following a year-long upgrade project.
The 19-mile line was energized last week following a year of construction activities to replace 60-year old poles and wires. “This work was done in part to address issues related to the age and condition of the facilities,” said Mary Carpenter, local relations representative. “The upgrade was also necessary to accommodate the additional output from the Port Washington Generating Station when the first of two new units is soon placed in service by We Energies.”
The need for a heaver-weight wire to carry more electricity called for the construction of stronger structures (poles). In general, the new structures were placed in the same position as the old structures. “Moving power from the generation source to where it’s needed was the goal of this project,” explained Carpenter. “This line also will strengthen reliability throughout the area.”
