Plainville Community Electricity Aggregation (CEA)

Plainville CEA is an electricity supply program organized by the town of Plainville 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

The aggregation programs for all municipalities participating in the MASSCEA buying group have been renewed for an additional term through late fall 2025. New pricing, shown below, will go into effect starting December 2023. The programs’ supplier will remain Constellation.

Most customers do not need to take any action to receive the new pricing. However, due to requirements from the Department of Public Utilities, customers currently in the 50% or 100% Green products must affirmatively re-enroll or their accounts will be disenrolled from the CEA returned to the utility Basic Service.

To re-enroll we recommend submitting a request through the enroll form below. Alternatively you can contacting the supplier, Constellation, at (833) 461-0813.

In addition to the standard electricity supply product, the Program also offers an option with 100% total energy from 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 in the Resources section for an illustration of a simple way to tell if you a part of the CEA program.

Products described as Green contain renewable electricity above that required by Massachusetts. The additional renewable electricity qualifies for MA Class I designation.

Please note: Prices for all products in the program include a 0.1 ¢/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.

For Commercial and Industrial National Grid Basic Service Rates please check out the National Grid supply rates page.

*Disclaimer: A goal of the CEA 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 change products.

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. Full enrollment in your chosen product is pending, based on the utility’s acceptance of your submission. If accepted, your program rate will be reflected in the Supply section of your utility bill in one to two billing cycles. 

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!

Please note: If you have a supplier block on your Utility account the supplier will not be able to enroll you in Community Electricity Aggregation. To check if you have a block and/or to remove a block please contact National Grid at (800)- 322-3223 or Eversource at (800)-592-2000

Renewable Energy in the Plainville Community Electricity Aggregation program

The CEA program’s additional renewable energy, above and beyond 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. 

The Plus option is a good choice for those who want to combat climate change and reduce their fossil fuel emissions. It creates 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 a 100% renewable energy as an optional product. If just four percent of residential households opt up to the 100% renewable Plus product, 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, avoiding:

  • 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.
