Public Utility Regulatory Policies Act (PURPA) of 1978, Fact Sheet.
The Public Utility Regulatory Policies Act (PURPA) of 1978, passed under the Carter Administration in response to the 1973 energy crisis, sought to encourage energy conservation, use of renewable energy, and consumption of domestic sources of energy by creating a market for power from non-utility power producers. PURPA sought to reduce the monopoly power of regulated utilities by forcing them to purchase electricity generated by competing energy generators.
Why were utilities granted regional, regulated monopolies decades earlier? What might have been the pros and cons of deregulating the utility sector? What interests might be served by deregulation?
