Community Choice Energy

We're giving Boston residents greater control over the kind of energy they use in their homes, and the price of that energy.

Through this program, the City of Boston will pool the buying power of electricity customers. This will give communities the chance to buy energy as a group for everyone. This type of program is also known as municipal aggregation, or community choice aggregation.

What is Community Choice Energy?

Through Community Choice Energy, cities and towns combine the buying power of electricity customers in their communities.

Creating bulk buying groups

Under this type of program, cities and towns enroll residents who receive default electricity service into a single buying group. They may also require a greater percentage of renewable energy than the mandatory amount set by the state.


The City of Boston is committed to being carbon neutral by 2050.

Carbon neutrality means that Boston can only release as much carbon pollution as our local environment can absorb. To get to carbon neutrality, Boston must run on clean energy.

Benefits of the program

"Green" municipal aggregation is one of several tools Boston can use to buy more clean energy and reduce carbon pollution. This program may also allow Boston residents to:

Proposed Plan

Boston's Community Choice Power Supply Program Aggregation Plan is now available for public comment.

All comments must be received by Friday, May 17. The plan will then be filed with and approved by the Department of Public Utilities, which offers its own public comment period.

Read the Plan

View Public Notice

The plan sets out the rules for how the aggregation will work, including:
  • eligibility
  • voluntary participation
  • right to opt out at any time
  • equitable treatment for customers in the same class, and
  • enrollment and billing processes.
The plan does not:
  • set prices
  • establish the amount or type of carbon free generation which will be included, and
  • establish the term of the contract.

Those matters will be determined by the City after the plan is approved. The City is working with a community working group to explore those issues.

How to comment

If you would like to comment, you may do so in person at the City Clerk’s office, or you can submit written comments. Please email with “City of Boston’s Aggregation Plan” in the subject line, or mail your comments to:

Please note:

Comments must be clearly marked "City of Boston’s Aggregation Plan." They must be received (not postmarked) by 5 p.m. Friday, May 17, 2019, to be considered.


The City will follow the steps toward aggregation as laid out by the state. We will work with the state and a consultant to prepare a plan and get community feedback.

The City is also convening a working group to inform the proposed plan and guide how we put it in place. After we are approved by the Massachusetts Department of Public Utilities, the City will be able to start the program.

CCE Progress

We’re excited to work with Colonial Power Group and Community Paradigm Associates. They will help us design and roll out our Community Choice Energy program.

Colonial Power Group helps Massachusetts cities and towns launch and manage energy aggregation programs. They’ve brought their expertise to more than 60 municipalities so far.

Community Paradigm Associates specializes in municipal law and process. They will also help us with collaborative decision-making and community engagement. 

Working Group

The City is convening a working group of Boston residents. As we develop the Community Choice Energy program, they will serve as:

  • experts
  • advocates, and
  • community leaders.

The group will meet often over the duration of this process. For questions about the working group, please contact the Environment Department.
