Quad County Electric Reliability Project

Project overview The Quad County Electric Reliability Project involves rebuilding existing transmission lines to improve electric system reliability in portions of four Wisconsin counties: Waukesha, Jefferson, Dodge and Washington. American Transmission Co. is rebuilding approximately 58 miles of aging, 138,000 volt┬átransmission lines stretching from Waukesha to Watertown and northwest toward Slinger. The reconstruction is needed […]

Mackinac HVDC Flow-Control Project

Project overview ATC is installing a high-voltage, direct current flow-control device and building the new Mackinac Substation near St.Ignace, Mich., to better manage power flows into and out of the Upper Peninsula. Need Despite significant upgrades to transmission infrastructure in the Upper Peninsula in recent years, operational challenges remain due to the delicate balance that […]

Bay Lake Project

Project overview American Transmission Co. is proposing to reinforce the electrical transmission grid in the Upper Peninsula of Michigan and northeastern Wisconsin to address generation changes, changes in demand, the evolution of a wholesale electricity market and emerging reliability concerns. Although ATC has made reinforcements in the region in the past six years, the transmission […]

Whitewater-Mukwonago

Upgraded 22 miles of transmission line between the Whitewater and Mukwonago substations.

West Towne-Fitchburg-Tokay

Constructed six miles of new 69-kilovolt underground transmission line to connect the West Towne Substation and Fitchburg Substation to the new, MGE-built Tokay Substation.

Wempleton-Paddock

Added a second 345-kilovolt line to an existing line between southern Rock County and northern Illinois.

Venus-Metonga

Built new 13-mile, 115-kilovolt transmission line between Monico and Crandon, Wis.

T-20 Phase 2 (Weston-Rocky Run)

Replaced the remaining structures and insulators, added new conductors from Weston-Northpoint and installed optical ground wire (OPGW) from Weston-Rocky Run.

Shawano East-West
