ATC Underground Transmission Work Underway in Milwaukee

Construction is underway on the underground portion of American Transmission Company’s Western Milwaukee County Electric Reliability Project. The project involves construction of two sets of 138-kV lines, each 2 mi long, to connect a new We Energies substation to the transmission grid.

The two separate lines are needed to assure redundancy to the Milwaukee Regional Medical Center, which operates two Level 1 trauma centers. Although construction was not scheduled to start until next year, ATC took advantage of the opportunity to begin the underground portion ─about 1,250 ft ─ to coincide with underground road work being performed by the Wisconsin Department of Transportation.
