Windmills at Iron Range wind farm grind to a halt after defects found
Minnesota Power's Taconite Ridge wind farm isn't producing nearly as much electricity as anticipated in recent months, with seven of the 10 wind turbines shut off for repairs.
The $50 million project, built on 450 acres of land overlooking U.S. Steel's Minntac mine, came fully online early this summer. But this fall, inspectors with the turbine manufacturer discovered defects in seven of the wind turbines' blades. Those turbines were shut down.
