Gov. Jennifer Granholm says production is about to begin on the first large-scale wind turbines made entirely in Michigan that will be used by utility companies to provide electricity to customers.
She announced Tuesday that a significant power purchase agreement has been reached between Jackson-based Consumers Energy Co. and Traverse City-based Heritage Sustainable Energy.
Northern Power Systems will build the direct drive wind turbines in Saginaw. The turbines will be used in Heritage's wind farm in the Upper Peninsula's Delta County and the power will be sold to Consumers Energy. Heritage also plans to build another wind farm in Missaukee and Osceola counties.
Under a 2008 law, 10 percent of the state's energy must come from renewable sources by 2015.
