Since 1985, the Federal Energy
Regulatory Commission has encouraged the use of market-based
rates to make the electricity industry more efficient. Some
electricity is now marketed at regional exchanges and commodities
trading centers. This site provides links to the five functioning
independent system operators (ISOs) in the United States.
The Energy Information Administration compiles
selected annual statistics on wholesale trade. The complete
listing of electric utilities is found in the Form EIA-861
and more details on public utilities in the Form EIA-412.
