Oneida Street Station, also known as the East Wells Power Plant, was a power plant operated by The Milwaukee Electric Railway & Light Company. Constructed from 1898 to 1900, it was designed by architect Herman Esser in neoclassical revival style. The building is located in downtown Milwaukee, Wisconsin, at the Milwaukee River and Wells Street, which was once known as Oneida Street. The company began operating electric street cars in 1890. Their expanding network of streetcar and interurban railway lines were powered by several of their own power plants. As the company generated more power than they used, they sold the excess electricity, and, as Wisconsin Energy Corporation, eventually became the major supplier of power to eastern Wisconsin.
