Federal Energy Regulatory Commission (FERC)
An agency of the government of the United States created by an Act of Congress, the Department of Energy Organization Act, in 1977. This Act transferred to the FERC most of the former Federal Power Commission's interstate regulatory functions over the electric power and natural gas industries. The Act also transferred from the Interstate Commerce Commission the authority to set oil pipeline transportation rates and to set the value of oil pipelines for ratemaking purposes. In 1978, Congress passed the Natural Energy Act, broadening the FERC's jurisdiction and regulatory functions. The FERC now also regulates producer sales of natural gas in intrastate commerce. The FERC establishes uniform ceiling prices for each of several categories of natural gas, and these prices apply to all sales on a nationwide basis.
Federal Power Commission
An agency of the government of the United States created by an Act of Congress, the Federal Water Power Act, in 1920. Originally charged with regulating the nation's water resources, the FPC later assumed responsibility for regulating the electric power and natural gas industries that sell or transport electricity or gas for resale in interstate commerce. With respect to the gas industry, the general regulatory principles of the FPC were defined in the Natural Gas Act, as amended. In 1977, the FPC passed into history and the Department of Energy was created, incorporating the independent regulatory agency known as the Federal Energy Regulatory Commission.
