What Is GMA?
Massachusetts and Rhode Island state laws allow a city or town to choose the electricity supplier for residents and businesses within that municipality. This is called municipal aggregation or community choice aggregation. It allows for important energy decisions to be made at the local level rather than by an investor-owned utility or by a for-profit competitive electricity supplier.
Green Municipal Aggregation, or GMA, is a model we devised with energy broker Good Energy that adds more Class I or "new" renewable energy to residents' electricity at a competitive price. When a community decides to enact GMA, it goes out to bid for an electricity supplier and secures a long-term price and a cleaner electricity supply. That supplier replaces the utility's Basic Service, offers a more stable price (usually cheaper in the long run, too), and adds more renewable energy than required by state law.
