From an article in the Winona Daily News:

Winona County commissioners approved conditional-use permits Tuesday for a wind farm near Lewiston, Minn., that will be owned by a subsidiary of Gundersen Lutheran Medical Center as part of the company’s efforts to become energy independent by 2014.

The wind project calls for building three 404-foot-tall wind turbines and a substation on a 315-acre farm just north of Lewiston city limits, southwest of County Road 25 and Trestle Drive. Each turbine will have a 262-foot-tall tower, topped by a rotor with a 282-foot diameter blade.
