The SpartanSolar array in Cadillac, Michigan, located across from Wolverine Power Cooperative’s headquarters, is Northern Michigan’s largest solar array. The array is located on M-55 between Cadillac and Lake City.

The array was completed and began operation in December 2016 after 18 months of planning and just four months of construction, and was proudly built with Michigan labor, local contractors, and solar panels manufactured in Michigan.
