American Transmission Co. announces second open house for Wisconsin-Illinois Reliability Project

Residents can provide input on the project’s revised routes prior to the regulatory filing

PEWAUKEE, Wis. – American Transmission Co. is hosting its final open house for the proposed Wisconsin-Illinois Reliability Project from 4:30 to 7 p.m. on Thursday, April 28. The open house, which will take place at ThunderHawk Golf Club, 39700 North Lewis Ave., Beach Park, Ill., gives local residents and other stakeholders the opportunity to learn about the proposed routes and substation, and to provide feedback about the project. Components of the project include: constructing a double-circuit 345-kilovolt transmission line to connect to an existing line near Pleasant Prairie, Wis., and connecting that line to the ComEd transmission system through a proposed substation site on the north side of Rosecrans Road (Hwy. 173) in the Village of Wadsworth, Ill.

“Input from residents at our first open house on March 16 allowed us to further evaluate the preliminary routes and narrow them to two route options,” said Mary Carpenter, ATC local relations representative. “From this feedback, the project team believes we’ve developed the options that best meet our routing and siting criteria based on impacts, costs, constructability, operation and maintenance.”

The Wisconsin-Illinois Reliability Project addresses an electric reliability issue that occurs when there are high power flows on the transmission system from Wisconsin into Illinois. The transmission line could range from three to five miles and will provide a reliable, alternative power path to address emergency conditions and accommodate increased power flows. The transmission line and proposed substation is estimated to cost between $52 million to $63 million.

Regulatory applications for this project will be submitted to the Illinois Commerce Commission in mid-2016 and the Public Service Commission of Wisconsin in fall 2016. A decision from the each of the regulatory agencies is expected in early 2017 and fall 2017, respectively.
