The full form of PURPA is Public Utility Regulatory Policies Act. It’s used on Governmental ,Rules & Regulations in United States

The Public Utility Regulatory Policies Act (PURPA, Pub.L. 95–617, 92 Stat. 3117, enacted November 9, 1978) is a United States Act passed as part of the National Energy Act. It was meant to promote energy conservation (reduce demand) and promote greater use of domestic energy and renewable energy (increase supply). The law was created in response to the 1973 energy crisis, and one year in advance of a second energy crisis.

Upon entering the White House, President Jimmy Carter made energy policy a top priority. The law started the energy industry on the road to restructuring

The Public Utility Regulatory Policies Act of 1978 (PURPA) was enacted following the energy crisis of the 1970s to encour­age cogeneration and renewable resources and promote competi­tion for electric generation. It also sought to encourage electrici­ty conservation. Implemented by the Federal Energy Regulatory Commission (FERC or Commission) and the states, the statute imposes mandatory purchase obligations on electric utilities for power generated by cogeneration facilities and small power production facilities of 80 megawatts (MW) or less. Much has changed since enactment of the act 42 years ago, including the development of organized wholesale electricity markets, federal and state programs encouraging renewable resources, and the adoption of policies at FERC to promote open access transmis­sion policies. Utilities and state regulators have raised concerns with the Commission and Congress about PURPA’s implemen­tation and needed reforms to its mandatory purchase obliga­tion provisions. In response to the concerns, FERC is currently considering changes to its regulations implementing PURPA, and legislation was introduced in the House of Representatives in the 115th and 116th Congresses to modernize the statute. The American Public Power Association (APPA or Association) supports FERC’s proposed rule changes and believes PURPA needs to be updated to reflect today’s energy marketplace.
