Carver Community Electricity Aggregation

In early 2016, the town of Carver joined other Massachusetts communities to launch a Community Electricity Aggregation (CEA) program designed to provide residents and businesses with competitive choice and long-term price stability. Now, the program also provides options with more renewable electricity than the minimum required by state law. 

Electricity Options for Carver CEA

Starting on the electricity meter read date in January 2021, your electricity will be supplied by Constellation.

No action is needed to remain in the program on the default option.

In addition to the default option that meets the state mandated minimums for renewable electricity, the program also offers two options with 50% and 100% more renewable electricity. 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 Carver CEA program.

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. For additional detail on the additional renewable energy, read the Clean Electricity section.

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.

Community Electricity Aggregation program rate through January meter read

Until your January 2021 meter read, the following price will apply to the electricity you use while enrolled in the CEA program:

$0.10430/kWh for Residential, Commercial and Industrial customers.

This means that the electricity bill you receive in January, which covers the electricity used between December meter read and the January meter read, will reflect this rate. It will also include a statement alerting you that you’ve changed suppliers – this means simply that you’re participating in CEA and that your new supplier is now Constellation.

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.

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

Clean Electricity in the Carver 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. 

Opt Up to 100% Clean Electricity!

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 Clean Energy

Massachusetts requires all energy suppliers to include a minimum amount of MA Class I renewable energy that increases annually. If the supplier does not meet these requirements, the supplier is required to pay a penalty. This policy, called the Renewable Portfolio Standard, provides growing demand for renewable energy, which incentivizes new renewable generation facilities to be built.  

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.
