Green Municipal Aggregation (Community Choice Electricity)

We purchase additional renewable energy on behalf of residents of 39 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.

Key takeaways from our 2023 report on Massachusetts:

• Of the 351 municipalities in Massachusetts, 167 cities and towns currently have an aggregation plan approved by the Massachusetts Department of Public Utilities (DPU). See our new interactive map above!
  *Note that 49 cities and towns receive their power supply from municipal utilities. 
   
• These plans range from including no Class I renewable options (“brown”) to including 30% or more Class I renewable options than are required by state law (“very dark green”), depending on how much renewable content each municipality has opted to incorporate into their program.

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.
