Alliant Energy has electric and natural gas utility operations serving more than 1.4 million customers in Iowa, Illinois, Minnesota and Wisconsin. Alliant Energy’s service territory covers 69,000 square miles in the heartland of America and includes 9,700 miles of electric transmission lines and more than 9,000 miles of natural gas main. It is headquartered in Madison, Wisconsin with general offices in Cedar Rapids and Dubuque, Iowa. Alliant Energy maintains a strong fleet of fossil fuel and renewable generating facilities across the upper Midwest, generating more than 30 million megawatt hours of electricity each year. Alliant Energy owns three wind farms that are in full operation, with Whispering Willow Wind Farm – East located in Franklin County, Iowa.

Interstate Power and Light Company (IPL) and Wisconsin Power and Light Company (WPL) are Alliant Energy’s two utility subsidiaries. In 2012, Alliant Energy’s Iowa utility, Interstate Power and Light Co. (IPL), announced plans to construct, maintain and operate a new 650-megawatt electric generation facility in Marshalltown, Iowa. On June 4, 2014, Alliant Energy’s Iowa utility issued a news release announcing it “has received all of the necessary regulatory approvals and permits to issue a Full Notice to Proceed (FNTP) for construction of MGS” and that “construction on the approximate 650 megawatt, combined-cycle, natural-gas-fueled Marshalltown Generating Station (MGS) is now underway.” On July 15, Alliant Energy celebrated the groundbreaking with a formal ceremony that included in-person remarks from Gov. Terry Branstad (view Alliant Energy news release). It is expected that the MGS will begin commercial operation in the second quarter of 2017.
