Minnesota-Iowa 345 kV Electric Transmission Project

ITC Midwest is building a new high-voltage electric transmission line in southern Minnesota and northern Iowa. The line will reduce electric transmission system congestion, enable more electric generating sources to connect to customers, improve electric reliability and meet the region’s growing energy demands. The Minnesota-Iowa 345 kV line will run from ITC Midwest’s facilities in Jackson County, Minnesota, to a new ITC Midwest substation located near Winnebago, before turning south to connect to a new substation in Kossuth County, Iowa. Approximately 75 miles of the line will be located in Minnesota and approximately 25 miles will be located in Iowa.

Multiple Benefits
The Minnesota-Iowa 345 kV Transmission Project is ITC’s potion of one of 17 transmission projects that MISO, the independent regional transmission organization for the 11-state region that includes Iowa and Minnesota, studied and designated as a “Multi-Value Project” (MVP) because it addresses multiple needs and provides multiple benefits to the region. The Minnesota-Iowa 345 kV Transmission Project will bring four major types of benefits to southern Minnesota, northern Iowa and the rest of the MISO region: improved reliability, expanded access to generation sources, increased system efficiency, and new jobs and economic investment.

Mobilizing hundreds of workers adn millions of dollars in materials, ITC continues to make significant progress building the Minnesota-Iowa project to meet the region's growing energy demands. We continue to appreciate the gracious response and patience that crews have received from landowners during construction.
