American Transmission Co (ATC) has received approval from the Illinois Commerce Commission (ICC) to build a new transmission line project worth $31m in the US.

The 345kV Pleasant Prairie-Zion Energy Center project will extend 5.8 miles from the Pleasant Prairie Substation in Wisconsin to the Zion Energy Center Substation in Illinois.

ATC local relations representative Mary Carpenter said, "This project will help relieve transmission congestion and strengthen the electric system in southeastern Wisconsin and northeastern Illinois."

ATC's application for the Illinois portion of the line included a 1.8 mile preferred route, which was approved by ICC, and two alternatives.

The preferred route begins at the Illinois-Wisconsin border, heading south along the eastern portion of railroad right-of-way west of the Trumpet Park Subdivision, and ending at the northeast side of the Zion Energy Center Substation.

The company filed an application for the Wisconsin portion of the line to the Public Service Commission of Wisconsin in October 2011 and anticipates a decision next month.

If approved construction will begin in late 2012 to meet an anticipated in-service date of 2013, said ATC.
