What is Community Choice Electricity Aggregation?
Community Choice Electricity Aggregation (CCE) is a program in Massachusetts that came out of the Restructuring Act of 1997, specifically Chapter 164: Section 134. Aggregation of electrical load by municipality or group of municipalities; adoption of energy plan. The Act empowers cities and towns to create large buying groups of residential and business electricity accounts in order to seek bids for cheaper supply rates, essentially bulk-purchasing. The purpose of the Act was to ensure that the benefits of energy deregulation were passed onto residential customers and businesses by providing the ability to “aggregate” their accounts within their municipal boundaries in order to obtain competitive bids from Third Party Suppliers (TPS). Grouping residential accounts together creates economies of scale, enabling participating municipalities to achieve greater savings for account holders as a whole. You may find more information about the electric industry in the state by visiting the Department of Public Utilities (D.P.U) website or the Department of Energy Resources website on municipal aggregation.

What are the objectives of community choice electricity aggregation?
The objective of CCA is simply to lower the cost of electricity bills through the formation of a buying group composed of residents and businesses of one or more municipalities without interfering with the level of service provided by the utility, in this case, Eversource, distributing the electricity supply.

How does community choice (electricity) aggregation work?
First, the municipality must pass an article at a town meeting or a motion at City Council. The municipality then selected Good Energy, L.P. to seek bids from TPS to obtain competitive electricity rates for participants. An account holder will be able to opt out of the program during a 30-day period at the onset of the program. They may also leave the program at any point with no associated termination penalties or fees.

How does community choice (electricity) aggregation impact my electricity bill?
The goal of CCA is primarily savings and long term price stability, though savings cannot be guaranteed, due to the fact that there is no visibility into future rates. Participants will see no change in their utility bill other than a change in price on energy supply. They will continue to receive a single bill, make one payment, and continue to receive the same level of service from Eversource.

What other Massachusetts municipalities participate in aggregation programs?
Arlington will be joining over 60 Massachusetts municipalities, including Somerville, Winchester, and Brookline, to take advantage of the state law that allows this type of municipal aggregation. View a list of them on them here.

Will the single bill come from Eversource?
Yes, your single bill will continue to come from Eversource.

When will the community choice (electricity) aggregation go into effect?
The program will launch in August, 2017. Participants will see the new supply charge reflected on their September bill for the previous month’s service.

What do I need to do in order to participate?
If you are currently receiving your electricity supply from Eversource basic service, you do not need to do anything. You will automatically be enrolled in the program unless you choose to opt out.

Do I have to participate in the community choice (electricity) aggregation program if I don’t want to?
No, residents and businesses can opt out without penalty during a 30-day opt-out period. Opt-out notices will be provided via USPS mail prior to the program commencing. Simply return the opt-out notice within 30 days and your account(s) will not be included. Participating account holders may leave the program at any time without penalty.

What part of my electricity bill will this program affect?
Your electricity bill has two cost components – delivery and supply. The aggregation program only changes the supply component of your bill. The delivery portion of your bill will not be affected.

When will I begin seeing a change in my electricity bill?
Enrollment will take place in July, 2017. The program will then actually begin in August. Changes will be reflected on the following billing cycle.

Under the program, can I continue to participate in Eversource’s budget billing/equal payment plan?
Yes, you can continue to participate in a budget billing/equal payment plan.

Will the community choice (electricity) aggregation program include both electricity and natural gas?
No, the program will focus exclusively on electricity.

What if I choose to leave the program early?
Residents and businesses who are enrolled in the program may terminate their participation at any time without any early termination or exit fees.

How will I be notified that my account(s) was successfully enrolled in the community choice (electricity) aggregation program?
Each eligible account holder will receive written notification after the bid informing them of the winning supplier price compared to Eversource’s rates, in addition to the account holder’s right to opt out. After the 30-day opt-out period has ended, each eligible account holder will receive a letter from Eversource confirming enrollment and that supply service will soon be switched to the winning supplier.

Can businesses participate in the program?
Yes, any account currently on basic service that is not enrolled with a TPS is eligible and will be automatically enrolled unless they choose to opt out.

I switched to a third party supplier and a few months later, my rate increased and I was paying much more than the utility rate. How do I know this won’t happen again by participating in this program?
The final contract will require the winning supplier to maintain the new rate for the entire term. This is called a fixed rate.
Please note: the Town will re-evaluate pricing for the additional local renewable energy portions for the Arlington Local Green, Arlington Premium 50% Local Green, and the Arlington Premium 100% Local Green options after 18 months. This may result in new pricing for the January, 2019 – December 2019 period for the Local Green options only.

How do I know the community choice (electricity) aggregation rate will always be below the utility rate?
The consultant has extensive knowledge of how utility tariff rates are determined, and as such, has structured a term with the goal of providing annual savings throughout the term of the contract.

How are we sure that a competent and reputable supplier was selected? 
Only TPS licensed by the state were eligible to bid. In addition, an in-depth request for proposal was disseminated by the energy consultant to interested TPS requiring them to provide their qualifications. Among other things, the request required suppliers to demonstrate financial strength, experience, in addition to customer service capabilities.

Will my utility be eligible to bid?
No, by law, utilities are not permitted to bid. With regard to supply, the utility only provides default service, however, the utility will always be responsible for delivering your electricity.

How long will the contract term be for?
The contract term will be 28 months in duration.

Do I have to sign a contract?
No, there is no contract to sign. The program is designed to be as easy as possible for participants. Accounts are automatically enrolled as long as they are currently receiving supply from the utility. Regular updates will be posted on the municipality’s website as the opt-out period approaches.

If I opt out, can I opt back in at a later date?  
Residents and small commercial accounts who are enrolled in the program may terminate their participation in the program at any time without any early termination or exit fees. They may also re-enroll in the program at a later date with no associated re-enrollment fees at the rates scheduled under the original program terms. The aggregation program rate will be reflected on the account holder’s utility bill on the next available billing cycle. Because switching suppliers requires at least two days to process by your utility, you are encouraged to re-enroll in the program at least five business days prior to the meter read date indicated on your utility bill in order to ensure re-enrollment occurs on a timely basis.

What if I have a photo-voltaic or solar panel system?
Having a solar system which allows you to earn net metering credits, e.g., Solarize Arlington, does not preclude you from participating in the aggregation program. As long as the account holder is receiving supply from Eversource, they are able to participate in the aggregation program and will continue to receive net metering credits from the utility. Net metering will work in the same way as before you joined the CCA program. Your net metering credits will continue to appear on your Eversource bill and will continue to be calculated based on Eversource’s Basic Service price. In addition, there is no change in SREC eligibility or the ability to sell the SRECs. For a more detailed explanation, please click here.

Who do I call if there is an outage or issues with my electricity bill?
All service and billing questions will continue to be directed to Eversource at
(800) 592-2000.

How do I contact the winning supplier?
Dynegy is the winning supplier for the program. They may be reached by phone Monday through Friday from at 9AM to 8PM EST (866) 220-5696, or via email at

Will the utility take longer to restore my electricity if I am with a third party supplier? 
No, the delivery of your electricity is always the responsibility of the utility. As a result of energy deregulation in 1997 in Massachusetts, utilities are only able to collect revenue from delivering the power to your meter, not from the actual supply. This is why utilities in Massachusetts are indifferent to the supply portion of the bill. Simply put, your utility does not make any money on the actual electricity they supply to your account(s). They only generate revenue from the delivery of that electricity.

Will I be charged a higher delivery rate?
Delivery rates do not change based on participation in a CCA program. Utility delivery rates are regulated by the state and the Federal Energy Regulatory Commission (FERC).

I am currently receiving offers from third party suppliers promising lower electricity rates. What should I do?
TPS are currently very active within the Commonwealth. This is due to the recent significant increases in electricity rates for all utilities within Massachusetts. We strongly advise any account holder to read the complete contract fine print and have a clear understanding of any termination penalties, along with rate details, before agreeing to purchase electricity from a TPS.

Will other third party supply offers stop if I participate in the program?
No, unfortunately you may continue to receive other TPS offers. It is important, therefore, to remember the details of the aggregation program, i.e., the duration of the program, rate, etc. Very often, due to the length of time commonly associated with these types of programs, participants forget the program is still in effect, when in fact there may be months or even years remaining. Sometimes this results in a participant inadvertently leaving the program for what they may believe to be a better offer. You are encouraged to remember that the CCA program is operated under the due diligence of your municipality and though not impossible, it is unlikely that other offers will be more competitive. Please regularly visit this site and your municipality’s site(s) for updates.

Does my municipality profit from the program?
No, your municipality does not profit from a CCA program.

What administrative functions will the municipality be performing related to this program?
The energy consultant will be responsible for managing all aspects of the program and keeping the municipality appropriately informed.

How can I get more information about the community choice (electricity) aggregation program?
Various public meetings and information sessions will take place in your area. Please check for announcements from your municipality and local news outlets.

What if the selected supplier goes out of business or is bought?
Good Energy’s due diligence process required bidding suppliers to meet strict qualification requirements. Among other things, the request required suppliers to demonstrate financial strength and experience, as well as customer service capabilities. This process minimized any chance of a supplier going out of business. If the supplier is bought, the purchasing entity will continue to provide supply service under the existing contract terms.

Is there any change to my meter? If so, how/who reads the meter?
No, there are no changes to your current meter. Eversource continues to read your meter.

Is a deposit required?
No, no deposit is required.

What happens at the end of the community choice (electricity) aggregation supply contract term?
Good Energy will work with your community to obtain renewal pricing. Similar to the original term, eligible customers will be given the opportunity to opt out.

Does the municipality pay any administrative fees?
No, the municipality does not pay any administrative fees.
