Green Municipal Aggregation (Community Choice Electricity)

We purchase additional renewable energy on behalf of residents of 42 communities, and the cost of that is included directly on their electricity bills within the supply price. Because we are a 501c3 nonprofit, payments for additional renewable energy are considered charitable contributions and are federally tax-deductible if you itemize.

Municipal aggregation (often called Community Choice Electricity) is the process by which a municipality (a town or city) purchases electricity in bulk from a competitive supplier on behalf of the residents and businesses within the community. The fundamental characteristic that distinguishes GMA from traditional aggregations is that the default electricity supply in a GMA includes more Class I renewable content than required by the Massachusetts Renewable Portfolio Standard (RPS) and Clean Energy Standard (CES).

This process 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 that our organization devised with energy broker Good Energy so that communities could support local renewable energy. When a community decides to enact GMA, 

• it undergoes a municipal process to approve and pass GMA,
• it goes out to bid for an electricity supplier and secures a long-term price and a cleaner electricity supply, and
• that supplier replaces the utility's Basic Service on residents' bills, offering a more stable price (usually cheaper in the long run, too), and adding more renewable energy than required by state law.
