The electric utility company serving Chicago is Commonwealth Edison, which had been formed by Samuel Insull. In 1902, a contract was signed with the Lake Street Elevated Railroad, whereby the elevated company would purchase its power from the utility. In 1911, Insull acquired control of all four elevated companies, which became the Chicago Rapid Transit Co. And in 1913, the three power plants which had been owned by elevated railroads were transferred to Commonwealth Edison ownership. Commonwealth Edison subsequently phased those plants out, in favor of their own larger power plants. Insull controlled Commonwealth Edison and the Chicago Rapid Transit Co. until 1932. The Chicago Rapid Transit Co. actually was a subsidiary of Commonwealth Edison from 1924 to 1938.
