Consumers Energy's largest power plant is the coal-powered J.H. Campbell power plant between Holland and Grand Haven. The other remaining coal-fired plant is the D.E. Karn generating station located on Saginaw Bay near Bay City. The Cobb power plant in Muskegon; the Whiting power plant on Lake Erie in Luna Pier, just north of the Michigan-Ohio state line and the J.C. Weadock Generating Plant were all coal plants that ceased operating in 2016. Consumers Energy plans to close its remaining coal plants by 2040.
