Alliant Energy to add more renewable energy

Wisconsin customers to benefit from clean, affordable wind power


MADISON, Wis. – December 13, 2018 – Alliant Energy’s Wisconsin energy company has received oral approval from the Public Service Commission of Wisconsin (PSCW) to build a wind project that will keep energy costs low for Wisconsin customers starting in 2020. The 150-megawatt wind farm located in Kossuth County, Iowa, will provide enough energy to power 57,000 Wisconsin homes and businesses.

“Our customers look to us for sustainable energy solutions,” said John Larsen, president of Alliant Energy. “Investing in state-of-the-art wind generation continues our path to lower carbon emissions and furthers our commitment to provide reliable and affordable energy to our customers and communities.”

The new wind farm in north-central Iowa is in an area with consistently strong wind resources. In addition, the cost to build new wind projects has decreased significantly, which is directly benefiting customers. This is largely the result of continued technological advancements that improve the efficiency of wind turbines, producing more energy for less cost.

Construction of the new wind farm is expected to start in 2019, with completion by fall 2020. Including this project, Alliant Energy’s energy companies in Wisconsin and Iowa plan to invest a total of $2 billion to add 1,150 megawatts of new owned wind generation by 2021. These significant investments are helping the company achieve its target of reducing carbon dioxide by 40 percent by 2030 from 2005 levels.

Alliant Energy’s Wisconsin energy company provides service to 470,000 electric and 190,000 natural gas customers in 35 of the state’s 72 counties. The company delivers the energy solutions and exceptional service customers and communities count on – safely, efficiently and responsibly.
