The 100MW Lake Winds energy park will produce enough electricity to meet the annual power needs of about 31,000 residential customers.
The special land use application included detailed site layouts for 56 wind turbines, as well as three alternate locations.
All of the turbine locations received previous approval from the Federal Aviation Administration, Michigan Aeronautic Commission, and the Mason County Airport Zoning Board of Appeals.
The Lake Winds facility is expected to provide Mason County taxing units with an additional $29m in property tax revenue over the first 20 years of operation.
Earlier, Consumers Energy announced its selection of the Vestas V100-1.8MW wind turbine for this project, and its selection of White Construction to construct the Lake Winds power project.
