State Rep. Triston Cole of Mancelona today recognized the Mio Dam for its induction into the Hydro Hall of Fame.
The Consumers Energy facility on the Au Sable River received the honor last week during a ceremony in Denver, Colorado. The Hydro Hall of Fame recognizes extraordinary achievements with an emphasis on long-lasting facilities.
The Mio Hydroelectric Plant has been generating energy for more than a century and still operates with its original turbines and generators. It was the first dam to use an under-sluice spillway, using passageways built into the foundation under its powerhouse so it is able to operate in a narrow space between the river’s embankments.
“The Mio Dam is innovative and historically significant, and an important component in supplying power to northern Michigan,” Cole said. “This honor is well-deserved.”
The 4,900-kilowatt facility began operating in 1916. It was named a Michigan Historical Site in 2005.
