Hamilton Community Choice Aggregation

Hamilton CCA is has been renewed for another three years, from December 2020 until December 2023. The program is adding a new renewable electricity option with 50% more renewable electricity than required by the state. Learn about all the options and pricing.

No action is required to continue with the program.

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 through a competitive bidding process. 

Program options

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

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.

National Grid Basic Service Rates

$0.12388/kWh for Residential, November 2020 – April 2021
$0.10763/kWh for Commercial, November 2020 – April 2021
$0.11325/kWh for Industrial, November 2020 – January 2021
Future savings against National Grid’s fixed Basic Service rate cannot be guaranteed because National Grid’s rates change every six months for residential and commercial customers and every three months for industrial customers.

Goals of Hamilton CCA

Competitive Pricing

Hamilton CCA seeks to procure electricity supply contracts when the market is favorable. Combined with the bulk-buying power of thousands of households and businesses in the program, Hamilton CCA aims to produce savings for customers compared to National Grid’s Basic Service rates. Savings, however, cannot be guaranteed.1

Price Stability

Hamilton CCA secures multi-year, fixed price contracts. In contrast, National Grid Basic Service rates change every six months for Residential and Small Commercial customers, and every three months for Industrial customers.2 

Local Renewable Energy

Hamilton CCA’s standard product includes five (5) percent more local renewable energy, known as Massachusetts Class I, than required by the State. This means you can have cleaner electricity, while helping to support the growth of renewable energy in our region. The Program also includes three optional products which include either 50% or 100% more renewable energy than is required by the State, or no more additional renewable energy than is required by the State.

No Obligation

Hamilton CCA allows participants  to leave the program or switch between options within the program at any time and without penalty.

How to Participate in Hamilton CCA

If you are not already participating in Hamilton CCA, you can enroll in any of the available products at any time by completing the enrollment form

As of the first meter read in December 2020, all eligible accounts already participating in Hamilton CCA will be automatically transferred to the electricity service at the new rates.

That means no action is necessary to participate! 

  • If you would like to choose one of the other options, please complete and submit the enrollment form
  • If you would not like to participate (opt out), please complete and submit the opt-out form

If you already have a competitive electricity supplier, you may enroll in the Hamilton CCA program when your existing contract ends. Or, if you are thinking about terminating your existing competitive electricity supply contract early, be sure to find out if there are penalties or fees for early termination before making your decision.
