The B.C. Cobb Plant, owned by Consumers Power Co. (now Consumers Energy), was a coal-fired plant that produced electricity for 66 years in Muskegon. This exhibit tells the story of the plant from its beginning until it was decommissioned in 2018. It includes a scale model of the plant and grounds, a collection of vintage house meters, a real power pole with all the equipment and a hands-on display that demonstrates the amount of wattage used by various light bulbs.
