The Iowa Utilities Board issued an order approving the Iowa portion of the Cardinal Hickory Creek transmission line last week.
This line will increase the amount of renewable energy able to access the power grid in the Midwest. The line will stretch approximately 102 miles from Dane County, Wisconsin to Dubuque County, Iowa and cross the Mississippi River. The Iowa side of the line is about 14 miles long, according to an ATC news release.
These improvements to the power grid will increase service reliability, enable the expansion of wind energy in the Midwest and provide economic benefits to the state of Iowa. It will also allow over 5,000 megawatts of renewable energy to enter the grid, and the subsequent expansion of wind energy in the state will increase land lease payments to farmers and revenue to local governments, according to an Iowa Environmental Council news release.
The line’s Mississippi River crossing raised some concerns over impacts on fish and other wildlife. However, the necessary regulatory approvals have been obtained from the U.S. Fish and Wildlife Service and the U.S. Army Corps of Engineers, and those in charge of the project kept environmental impacts in mind when choosing the location of the crossing.
Construction of the line will begin in the spring of 2021, and it is set to go into service in 2023.
