Cardinal-Hickory Creek Transmission Line Project

American Transmission Co., ITC Midwest LLC and Dairyland Power Cooperative have plans for a high-voltage transmission line connecting northeast Iowa and western Wisconsin that would provide economic savings, support renewable energy policy and improve electric system reliability. A study area from Dubuque County, Iowa, to Dane County, Wisconsin, has been identified for the approximately 125-mile, 345-kilovolt line. Studies indicate that the Cardinal-Hickory Creek Project is a multi-benefit project that would deliver benefits to local communities and the Midwest region by:

  • Improving electric system reliability locally and regionally
  • Delivering economic benefits for utilities and electric consumers
  • Expanding infrastructure to support public policy for greater use of renewables
