IPL and enXco announced their plan to build the wind farm in April, 2008. The original plan called for 67 GE 1.5 MW wind turbines. By the time construction started in April 2009, the plan had changed to use REpower 2.0 MW wind turbines instead, with 80m towers. At the time of construction, Hoosier was only the third wind farm in the United States to use REpower wind turbines, after Goodnoe Hills Wind Farm in Goldendale, Washington, and Shiloh Wind Farm Phase II in Birds Landing, California (also constructed by enXco and Mortenson). Construction took six months.
The groundbreaking ceremony on April 17, 2009 included Indiana Lt. Governor Becky Skillman and other government and industry officials.
