Promoting Smart Growth & Regional Planning
Community Choice Aggregation
MAPC is committed to helping cities and town in the Commonwealth and the nation to develop green municipal aggregation programs that will truly reduce greenhouse gas emissions and fight climate change, as well as provide cost savings and price stability.
Municipal aggregation – also known as community choice aggregation - allows a city or town determine where its electricity comes from. The following page contains background information as well as links to MAPC's for more information.
In a municipal aggregation, a city or town contracts with an electricity supplier on behalf of residents and businesses who have not already selected a competitive supplier. Most residents and businesses currently get electricity supply, referred to as basic service, from their electric utility (e.g., National Grid or Eversource). Under state law, however, electric utility customers can choose an electricity supplier other than their utility, and the utility will continue to deliver the electricity, maintain poles and wires, and provide other customer services. Customers still receive a single electricity bill.
Goals of Aggregation
Typically, most aggregations in Massachusetts have pursued cost savings and price stability as primary goals. Aggregations can purchase for longer periods than the utility, providing more price stability. And aggregations can choose when to purchase, to take advantage of good market conditions.
Some aggregations have also set a goal of purchasing more renewable energy; however, these purchases were unlikely to lead to the construction of new renewable energy.
