Fairhaven Community Electricity Aggregation (CEA)

Tax Deductions: The cost of the additional renewable energy provided through Fairhaven Community Electricity Aggregation is eligible for a federal tax deduction. To receive a receipt to file with your 2022 taxes, you must fill out the form here. Hard copy letters are not being mailed.

Fairhaven CEA is a program offered by the town of Fairhaven to provide new electricity supply options and more renewable energy to Fairhaven residents and businesses.  The delivery of electricity and billing for use is still completed through Eversource, so customers continue to receive one bill from the utility.

The program began in 2016 and has been renewed for another 35 months, starting January 2021 through December 2023.

Electricity Options

At the beginning of the program in 2016 through 2020, Fairhaven’s program only met the mandated minimums for electricity purchased from renewable energy resources. In 2021, the program has added 10% of renewable energy certificates to the standard option and now offers two more options with 50% and 100% more RECs so you can make an even impact in your support for renewable energy resources in New England. You can sign up for either option, choose a basic option without extra renewable electrify, 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.

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

These rates are in effect from January 2021 through December 2023.
Products described as Green contain Renewable Energy Certificates (MA Class I RECs) above the amount required by the Commonwealth and come only from solar, wind, anaerobic digestion and low-impact hydro located within New England. Local refers to generation located in New England.

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.

Renewable Energy Certificates (RECs) are the accepted legal instrument used to track renewable energy generation and to substantiate claims of renewable energy use. The additional RECs voluntarily purchased by the program qualify for MA Class I designation.

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

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 Fairhaven CEA

Fairhaven CEA is committed to supporting the growth of new renewable energy resources in our region. While the Commonwealth requires electricity consumers to include more renewable energy generation over time, the pace of change needs to be faster to mitigate the effects of climate change. Fairhaven Community Electricity Aggregation is leveraging the buying power of our community to support renewable energy generation in New England.

Using our combined buying power for change

Fairhaven’s standard product, Local Green, includes 10% Renewable Energy Certificates (MA Class I RECs), in addition to the requirements of the Commonwealth (Read more about the renewable energy requirements in Massachusetts). Most residents and businesses in Fairhaven participate in the program and use the Local Green product. Across our entire community, these additional REC purchases add up to a substantial impact. For those who want to accelerate the transition to a sustainable future, the Fairhaven CEA offers electricity products that add 50% and 100% renewable energy certificates (MA Class I RECs). 

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

Supporting renewable resources on our electricity grid

All of the additional RECs in Fairhaven CEA come from MA Class I resources that are part of our ISO-New England electricity grid. This means the energy sources 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. 

Fairhaven CEA goes even further: all of our MA Class I RECs come from sources exclusively located in New England. See below for a map of our sources.

Location matters

Our REC purchases stands in contrast to some electricity supplies who obtain RECs from national sources (e.g. Texas), where the electricity is not part of our ISO-New England electricity grid.  These suppliers  purchase national wind RECs for a fraction of the cost of a New England equivalent, but you get what you pay for: national wind RECs are cheap because places like Texas, where they are often sourced, don’t have high development costs for energy projects. To change our electricity generation from burning natural gas and other fossil fuels to renewable sources, our program purchases RECs that are sourced in New England and meet the MA Class I standards. That way, our program is supporting the fuel shift and the transition to a sustainable future. 

Supporting Zero-Emission and Methane-Destroying sources

Fairhaven CEA’s extra RECs only come from zero emission sources, such as solar, wind, low impact hydropower1, and sources that destroy methane, such as anaerobic digestion. Methane has a global warming potential (GWP) 28-36 times greater than CO2 over a 100 year period2. Combustion destroys methane and releases some CO2, resulting in a net reduction in GWP. Other forms of biomass are explicitly not purchased, due to their positive emissions of CO2 during their life cycles.

All of the extra renewable energy certificates in the Fairhaven CEA are provided through the local non-profit, Green Energy Consumers Alliance.

Resources that have recently been, are in, or are contracted with Green Energy Consumers as of October 2020.

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.
