was separated from the turbine turning it by about a rope belt pulley system. As new uses and users for electricity increased, by the early 1900s the demand for electricity in Sacramento and its adjacent cities had out-paced the capacity of the expanded Folsom Powerhouse. Larger hydroelectric plants and dams were built along the Yuba, Feather, and Tuolumne Rivers in order to provide power for Northern California. The San Francisco-based California Gas and Electric Company bought the Folsom Powerhouse by 1902. When the company was reorganized into the Pacific Gas and Electric Company in 1906, it retooled the powerhouse and forebay.
