Enacted in 1920, and amended in 1935, the Act consists of three parts. The first part incorporated the Federal Water Power Act administered by the former Federal Power Commission, whose activities were confined almost entirely to licencing non-Federal hydroelectric projects. Parts II and II were added with the passage of the Public Utility Act. These parts extended the Act's jurisdiction to include regulating the interstate transmission electrical energy and rates for its sale as wholesale in interstate commerce. The Federal Energy Regulatory Commission is now charged with the administration of this law. See Federal Power Act of 1920.
