As part of the Green Communities Act of 2008, the Renewable Portfolio Standard (RPS) in Massachusetts is one standard that requires retail suppliers of electricity to get a certain percentage of the electricity they sell to customers from qualifying renewable energy generating facilities, such as solar energy systems and wind turbines. Each year since 2009, the amount of electricity that suppliers need to source from renewable energy generating facilities increases by 1%. Currently, all electricity suppliers in Massachusetts must have 14% of electricity they supply from renewable energy generating facilities in the state under RPS requirements. Other programs adopted by Massachusetts that continue to make our electricity supply 'greener' can be found on the DOER's Program Summaries page

If you would like to have more of your electricity come from renewable resources, you can purchase renewable energy credits or select a competitive electricity supplier that will purchase renewable energy credits for you. Learn more about renewable energy credits and competitive suppliers here.
