Alliant Energy will build another wind energy plant in Iowa

Alliant Energy Corp. will build another wind farm with 60 wind turbines, even though its two regulated utilities already are on track to comply with renewable energy targets in Wisconsin and Iowa.

Alliant will build a 100-megawatt wind farm in Franklin County, Iowa, by the end of next year, company Chairman and Chief Executive Bill Harvey said. In an unusual move, the $235 million wind farm will be built by the parent company rather than its Wisconsin or Iowa utility.

Power generated by the wind turbines could be sold to either of Alliant’s two utilities — Wisconsin Power & Light Co. in Madison or Interstate Power & Light Co. of Cedar Rapids. It’s also possible Alliant will sell the power to other companies or into the Midwest wholesale power market.
