Municipal Energy Aggregation

What is municipal aggregation?

Municipal aggregation is the process by which a municipality (meaning Canton, MA) purchases electricity in bulk from a competitive supplier on behalf of the residents and businesses within the community. 

In a municipal aggregation:

  1. Canton would procure competitive electric supply on behalf of participating customers.
  2. Canton could join with other municipalities to procure competitive supply.
  3. Customer participation is voluntary.  Canton will provide customers an opportunity to opt-out of participating in a municipal aggregation program.  Customers who do not opt out will be automatically enrolled in the aggregation program, but may opt out at any time after that.
  4. The electric utility company will continue to provide electric transmission and distribution service to participating customers.


How does a municipality create a municipal aggregation?

A municipality must:

  • Vote to initiate the municipal aggregation program (May 2021).
  • Prepare a municipal aggregation plan in consultation with the Department of Energy Resources, often in partnership with a consultant (Consultant search underway for this service).
  • Allow an opportunity for citizen review of the municipal aggregation plan.
  • Submit a municipal aggregation plan to the DPU for review and approval.
