What is PURPA

small solar arrayIn 1978, Congress passed the Public Utility Regulatory Policies Act (PURPA) to encourage fuel diversity via alternative energy sources and to introduce competition into the electric sector. The legislation originally encouraged industrial waste heat recovery and renewable energy resource development by small, non-utility power producers called "Qualifying Facilities" or "QFs." Now, wind and solar developers use PURPA to sell power at “avoided cost” rates to Oregon’s utilities. Although PURPA is a federal law, states are responsible for implementing significant aspects of the law, and Oregon has enacted its own complementary legislation in ORS 758.505, among others.
