We filed an application with the Public Service Commission of Wisconsin (PSCW) on Feb. 28 for authority to construct a new distribution substation and related distribution facilities in western Milwaukee County.
The Milwaukee County Substation would be built adjacent to our Milwaukee County Power Plant on Watertown Plank Road in Wauwatosa. The new substation is part of the Western Milwaukee County Electric Reliability Project we are planning jointly with American Transmission Co. (ATC).
To connect the new substation to the transmission system, ATC must build two 138-kilovolt (kV) transmission lines with two connections to the new substation. If approved by the PSCW, construction of the 138-kV lines is expected to begin in late 2014. ATC filed for regulatory approval to construct the two lines, which will run about two miles, on Feb. 27.
Over the past decade, the area surrounding the intersection of U.S. Highway 45 and Watertown Plank Road, commonly known as the Milwaukee County Grounds, has seen new development and associated electric load growth. Recent developments include the Milwaukee County Research Park, new facilities and expansions at the Milwaukee Regional Medical Center, and new commercial developments in the area.
The proposed project would meet near-term and long-term needs for additional, reliable and secure capacity. If approved, we likely would start construction of the substation in September 2014, with an anticipated in-service date of June 2015.
