Consumers Energy owns 13 hydroelectric facilities or dams along five rivers in Michigan. Built between 1906 and 1935, the hydros have a combined generating capacity of about 130 megawatts, enough to serve about 70,000 people. Near the hydros are campgrounds, boat launches and nature trails that are popular spots for canoeing, fishing and bird watching. The facilities are located on the Au Sable River (Mio Hydro, Alcona Hydro, Loud Hydro, Five Channels Hydro, Cooke Hydro, Foote Hydro), Grand River (Webber Hydro), Kalamazoo River (Allegan Hydro), Manistee River (Hodenpyl Hydro, Tippy Hydro) and Muskegon River (Rogers Hydro, Hardy Hydro, Croton Hydro). Operating since 1907, the Webber Hydro on the Grand River is the company’s oldest operating hydroelectric facility. The Croton Hydro on the Muskegon River was listed in the National Register of Historic Places on August 16, 1979.
