The first industrial use of hydropower to generate electricity in the United States was in 1880 to power 16 brusharc lamps at the Wolverine Chair Factory in Grand Rapids, Michigan. The first hydroelectric power plant to sell electricity opened on the Fox River near Appleton, Wisconsin, on September 30, 1882.
