In July 2008, Governor Patrick signed a major energy reform bill, the Green Communities Act (S.B. 2768). As part of that legislation, Massachusetts created the Alternative Energy Portfolio Standard (APS), which requires meeting 5% of the state's electric load with "alternative energy" by 2020 according to the following schedule:

  • 1.00% by 2009
  • 1.50% by 2010
  • 2.00% by 2011
  • 2.50% by 2012
  • 3.00% by 2013
  • 3.50% by 2014
  • 3.75% by 2015
  • 4.00% by 2016
  • 4.25% by 2017
  • 4.50% by 2018
  • 4.75% by 2019
  • 5.00% by 2020

The “alternative energy generating sources” include combined heat and power (CHP) projects, gasification with capture and permanent sequestration of carbon dioxide, flywheel energy storage, paper-derived fuel sources, or energy efficient steam technology. These projects must be new (start date after January 1, 2008) and must receive a statement of qualification from the Department of Energy Resources (DOER) to qualify.

In 2009 and 2010, ~99% of compliance was met using efficient CHP technologies.

Legislation passed in August 2012 requires that the state's executive office of energy and environmental affairs study adding technologies that generate "useful thermal energy" to the list of eligible technologies under this standard. That study will be completed by the end of December 2012.
