Established under the Massachusetts Electric Utility Restructuring Act of 1997, the Renewable Energy Portfolio Standard (RPS) was amended per the Green Communities Act of 2008 . The Green Communities Act spurred the development of three programs, introduced in January 2009:
- RPS Class I (evolved from the original RPS program)
- RPS Class II
- Alternative Energy Portfolio Standard (APS)
The revised and new standards are in the Massachusetts General Laws in Chapter 25A Section 11F (RPS Class I and Class II) and Section 11F 1/2 (APS).
