Hamilton CCA is a municipal aggregation, or Community Choice Aggregation, program operated by the Town of Hamilton. With Hamilton CCA, National Grid continues to deliver electricity and manage all electricity billing. The only change is the source and cost of electricity supply, chosen by the town of Hamilton.
Hamilton CCA has a standard option, Local Green, which has five percent more renewable energy content than required by state law. Participants in the program receive Local Green unless they affirmatively choose one of the other electricity options.
Includes 5% more Renewable Energy Certificates, than required by the Commonwealth
Local 50% Green
Includes 50% more Renewable Energy Certificates, than required by the Commonwealth
Local 100% Green
Includes Renewable Energy Certificates equal to 100% of the user’s electricity consumption, in addition to meeting all renewable energy requirements
Meets all Renewable Energy Certificate requirements
Hamilton CCA pricing will be in effect from December 2020 through December 2023.
Products described as Green contain renewable electricity above that required by state law. The additional renewable electricity qualifies for MA Class I designation and comes only from solar, wind, anaerobic digestion and low-impact hydro located within New England. Local refers to New England.
All of the additional Renewable Energy Certificates (RECs) included in the program are designated as MA Class I. RECs are the accepted legal instrument used to track renewable energy generation and to substantiate claims of renewable energy use. Learn more about the RECs that are included on the Renewable Energy page.

How to Participate in Hamilton CCA
Most residents and businesses in Hamilton already participate in the CCA program. Check your electricity bill to see if you’re one of them: the Supplier should be listed as Constellation – Hamilton CCA (click for a bill sample). If National Grid is still listed as your supplier, you may complete the enrollment form to sign up for Hamilton CCA. If a different supplier is listed, contact that supplier to check for penalties or termination fees that they may charge before you join the CCA program.
Participation in the Hamilton CCA program is voluntary: you can leave the program at any time without fee or penalty.
The program will periodically send Customer Notification letters to new or newly eligible electricity customers, which includes the program details, information about product prices, and renewable energy certificates. Customers who receive this letter and do not choose to opt out will be automatically enrolled. To enroll sooner, use our online form.
