Renewable Energy Portfolio Standard for Retail Electricity Suppliers

The Massachusetts Renewable Energy Portfolio Standard for retail electricity suppliers was established in Section 11F of the Massachusetts General Laws, Title II, Chapter 25A. It began with a requirement that suppliers source 4% of energy from renewable sources by 2009, and was updated by the Green Communities Act of 2008 to increase by 1% annually. Eligible technologies include solar thermal electric, landfill methane, anaerobic digester gas, geothermal energy, and biomass fuel.
