Dighton Community Electricity Aggregation (CEA)

Dighton CEA is an electricity supply program organized by the town of Dighton to provide residents and businesses with new, town-vetted options for electricity supply.  The delivery of electricity and billing for use is still completed through National Grid, so customers continue to receive one bill from the utility.

Electricity Options

In addition to the standard electricity supply product, the program also offers two options with 50% and 100% more renewable energy certificates. You can sign up for either option, return to the default or leave the program at any time. You can also check the sample bill for an illustration of a simple way to tell if you a part of the CEA program.

Dighton Community Aggregation Program rates

Standard ProductLocal Green 50%Local Green 100%
Renewable Energy Certificates (RECs)Meets all Renewable Energy Certificate requirementsIncludes 50% more Renewable Energy Certificates (MA Class I RECs), than required by the CommonwealthIncludes Renewable Energy Certificates (MA Class I RECs) equal to 100% of the user’s electricity consumption, in addition to meeting all renewable energy requirements
These rates are in effect for residential, commercial and industrial accounts from January 2021 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. Local refers to geographic areas permitted under MA Class I designation, namely New England, New York and eastern Canada.

Please note: Prices for all products in the program include a $0.001/kWh administration fee. Program prices apply only to the electricity supply portion of your electric bill. Delivery charges on your electric bill are not affected by the program.

For new Industrial customers and for those customers who have previously opted-out of the program, the Program’s supplier may offer a market rate.

RECs are the accepted legal instrument used to track renewable energy generation and to substantiate claims of renewable energy use.

Disclaimer: A goal of the program is to produce savings for customers, but savings cannot be guaranteed compared to the utility’s basic service rate which changes every six months for residential and commercial customers, and every three months for Industrial customers. The aggregation program seeks to provide price stability and average savings over the full term of the program, but because future basic service rates are not known, there is no guarantee of savings.

Enroll or change option

If you’re already participating in the Community Electricity Aggregation program, you can also use this form to sign up for additional renewable electricity with Local Green 50% or Local Green 100%.

Opting Up to 100% Local Green is a
powerful way to combat climate change!

If you are not participating in the Community Electricity Aggregation program, you can use this online form to enroll in one of the Community Electricity Aggregation options. If enrolling, once service has begun, your choice will be reflected on your following month’s electricity bill for the previous month’s service. Please note that based on your meter read date, it may take up to two billing cycles to get enrolled.

If you are currently a customer of a competitive supplier, you may be subject to penalties or early termination fees from your supplier if you switch from the competitive supplier to the Program during the term of your contract. There is no charge for leaving Basic Service, however, Industrial customers leaving fixed-price Basic Service may receive a billing adjustment  that may be a credit or a charge.

Be sure to use the name and address associated with the account!

Renewable Energy in the Dighton Community Electricity Aggregation program

The CEA program’s 50% Local Green and 100% Local Green contain additional renewable energy, above and beyond the state minimum requirements. All of this additional renewable energy qualifies for Massachusetts Class I (MA Class I) designation. MA Class I projects are located in New England, New York or Eastern Canada. The sources allowed under the designation are varied, but mostly include wind, solar, small scale hydro, and digester gas. 

Sign Up for 100%!

The 50% Local Green and 100% Local Green options are good choices for those who want to combat climate change and reduce their fossil fuel emissions.  They create more demand for electricity from renewable sources, which in turn incentivizes the development of new projects.

Helping to Build Renewable Energy Resources

Massachusetts requires all electricity suppliers to include a minimum amount of MA Class I Renewable Energy Certificates (RECs) that increases annually. This policy, called the Renewable Portfolio Standard, provides growing demand for renewable energy, which incentivizes new renewable generation facilities to be built.  All of the additional RECs in your program come from MA Class I resources that are part of our ISO-New England electricity grid. This means the renewable energy resources are located in New England or the energy is imported as allowed by ISO-New England from locations such as New York or eastern Canada. 

How big is our impact?

All 25 of the municipalities participating in the MASS CEA buying group, of which your community is one, offer 50% Local Green and 100% Local Green as optional products. If just 4% of residential households opt up (2% to 50% Local Green and 2% to 100% Local Green), it would result in extra demand equivalent to more than 10 typical onshore wind turbines (1.5 MW each). 

Those 10 wind turbines could power over 6,000 homes with clean energy and could displace over 45,000 MWh with clean electricity, which would avoid:

  • 29 million pounds of carbon dioxide, equivalent to taking over 2,800 vehicles off the road for one year
  • 3,600 pounds of sulfur dioxide
  • 6,750 pounds of nitrous oxide

Calculations based on ISO-New England emissions factors for 2017.
