ATC to discuss routes for proposed transmission line in Southeastern Wisconsin, Northeastern Illinois

Open house scheduled for April 6 at Pleasant Prairie LakeView RecPlex

PEWAUKEE, Wis. – An informational open house on Wednesday, April 6, will provide area landowners and members of the public an opportunity to comment on American Transmission Co.’s proposal for a new 345,000-volt transmission line to be built from Pleasant Prairie, Wis., to Zion, Ill.

“The project would improve electric system performance in the region and deliver economic savings for Wisconsin utilities and their electric consumers,” said Mary Carpenter, local relations representative for ATC.

ATC staff will be on hand at the LakeView RecPlex between 4 p.m. and 7 p.m. on Wednesday, April 6, to discuss with stakeholders the plans, including routes being considered for the transmission line.

“Because the distance between the Pleasant Prairie Substation and the Zion Energy Center is less than 6 miles, there are a limited number of corridors that would be suitable for a 345-kV transmission line,” said Carpenter.

ATC will continue public outreach before filing applications to build the line with the Public Service Commission of Wisconsin and the Illinois Commerce Commission in late 2011. If approved by the PSCW and ICC, construction of the new line would begin in 2013 to meet an in-service date of 2014.
