Fairhaven Community Electricity Aggregation

In early 2016, the town of Fairhaven 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 has increased the default electricity option to include an additional 10% renewable electricity in addition to new options with even more renewable electricity.

If you do not want to receive the additional 10% of renewable electricity, complete the Change Option form below and select Fairhaven Basic to continue to receive the aggregation program benefits, but without the additional renewable electricity.

Electricity Options

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

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

You can also check the sample bill for an illustration of a simple way to tell if you a part of the CEA program.

These rates are in effect from January 2021 through December 2023. Green refers to the extra renewable energy which qualifies for Massachusetts Class I (MA Class I) designation. It also meets additional standards to provide Fairhaven with the cleanest options and the most local impact: it comes only from Local projects – solar, wind, anaerobic digestion and low-impact hydro located within New England.

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% or to select the Fairhaven Basic option, which contains only the minimum amount of renewable electricity required by state law.

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.

Additional Clean Electricity in the Fairhaven CEA

Fairhaven is committed to supporting the growth of new, local renewable energy sources in our region. The State of Massachusetts has progressive policies that require the utilities to supply more renewable energy over time, however, the pace of the change needs to be faster to mitigate the effects of climate change. Fairhaven CEA is leveraging the buying power of our community to bring more clean electricity to our residents and businesses.

Fairhaven’s standard product, Local Green, has 10% extra renewable energy included, above and beyond the state requirements. 

Participating in Local Green 10% is only the first step in fighting climate change. Fairhaven also offers optional products with 50% and 100% renewable energy to let you take an even bigger step in the fight against climate change. 

Opt Up to 100% Clean Electricity!

Buying from New England, Buying Clean

In the Fairhaven CEA, all extra renewable energy qualifies for Massachusetts Class I (MA Class I) designation. It also meets additional standards to provide Fairhaven with the cleanest options and the most local impact: all renewable electricity is sourced only from New England and includes only wind, solar, small -scale hydro and digester gas plants.

Green Energy Consumers Alliance, the MA-based non-profit that sources for all of Fairhaven’s extra renewable energy, helps bring new renewable projects to New England through long-term contracts and strategic targeted project support. The renewable energy sources that Green Energy Consumers can provide to Fairhaven CEA are shown below.

Electricity generation sources, Green Energy Consumers Alliance

Only New England Sources

MA Class I-designated renewable energy can come from New England or adjacent parts of Canada and New York. It is one of the most stringently green standards in the country, but Fairhaven CEA is even better: we exclusively source our extra renewable energy from within New England. We’re helping to keep our energy impact local, supporting New England’s clean energy economy.

Only Zero-Emission or Methane-Destroying Sources

The Fairhaven CEA’s extra renewable energy only comes from zero emission sources, such as solar, wind, low-impact hydro1, or sources that destroy the potent greenhouse gas methane, such as anaerobic digestion2. Although traditional biomass, such as wood-fired generation, is eligible as MA Class I, the Fairhaven CEA does not include and does not plan to include any for its extra renewable energy. 

Helping to Build Clean Energy

Massachusetts has a requirement for every electricity supplier to include a minimum amount of MA Class I renewable energy, and that amount increases each year. If you don’t meet the requirements, you pay a penalty. This policy, known as the Renewable Portfolio Standard, provides growing demand for renewable energy, which incentivizes new renewables to be built. By purchasing a significant quantity of extra MA Class I renewable energy, Fairhaven CEA is increasing demand, incentivizing developers to build even more renewable energy projects.


1 Hydro projects that do not exceed 30 MW built after 1997 or have capacity additions or efficiency improvements made after 1997 (MA Class I eligible), and Low Impact Hydro Institute (LIHI) certified.

2 Methane has a global warming potential (GWP) 28-36 times greater than CO2 over a 100 year period. Combustion destroys methane and releases some CO2, resulting in a net reduction in GWP.
