$492 M power line and a substation in Wisconsin approved

US, Wisconsin: State utility regulators approved plans for a massive transmission line across central and southwestern Wisconsin that is projected to cost roughly $492 M.

The approximately 160 km (100 mile), 345 kV transmission line is designed to electrically connect the Dubuque County, Iowa region to the Dane County, Wisconsin, region. The project also includes the construction of a new substation in Montfort, Wisconsin.

The project β€” known as the Cardinal Hickory Creek power line β€” is a joint venture of ATC, Dairyland Power Cooperative, and ITC Midwest.

ITC and ATC each will own 45.5% of the line. The balance will be owned by Dairyland Power.

The line would be part of a larger transmission system, the Midcontinent Independent System Operator.

ATC, ITC Midwest and Dairyland Power Cooperative will begin contacting Wisconsin property owners along the route beginning this fall. Construction is expected to begin in 2021 to meet an in-service date of 2023 if final approval is granted by the IUB and federal agencies.
