The pipeline will "increase the quantity and reliability of natural gas service," the utility said.
The pipeline was planned before the Foxconn project, but the company has accelerated its timeline, said Amy Jahns, a spokeswoman for the utility.
"Specifically, right now the (Wisconsin Department of Transportation) is doing some road work, and so we are accelerating our timetable to coordinate with the DOT," Jahns said.
There are two different routes proposed for the project, though both would start in La Grange and end just west of the Foxconn site in Mount Pleasant. Both options could cover more than 200 parcels of land.
The northern route would cost $196 million and go through towns in Walworth and Racine counties. The southern option would cost $187 million and would run through Walworth, Racine and Kenosha counties.
