Program Details

IMPORTANT ENROLLMENT INFORMATION
Medford has renewed its Community Electricity Aggregation (CEA) Program, with new prices starting in December 2022. Current program participants do not need to take any action – you will automatically receive the new pricing as of December 2022. Most Medford residents already participate in the CEA Program. 

Because the Program is transitioning between suppliers, from the previous supplier, Dynegy, to the new supplier, NextEra Energy, Dynegy is no longer processing new enrollments. Those who wish to enroll in the Program should still complete the enrollment form, or contact NextEra Energy directly at (877) 960-8880. NextEra Energy will then process your enrollment to take effect in December 2022. The new program price will be reflected on your January 2023 bill for December 2022 service.

Click here to see the new prices, how to tell if you are a current participant, and how to join if you are not already a participant. Please call (833) 637-3232 with questions.


Medford Community Electricity Aggregation (CEA) is a program offered by the city of Medford’s Office of Planning, Development, and Sustainability is a program offered by the city of Medford to provide new electricity supply options and more renewable energy to Medford residents and businesses.  The Program doesn’t replace National Grid (or Eversource), the electric utility in Medford, that still continues to deliver electricity, repair outages and manager all billing, so that customers continue to receive only one bill from their utility.

Medford CEA is the only electricity program offered by our City – beware of look-alike offers and always look for the city seal on materials sent to you!

Enroll in the Program

Most residents and businesses in Medford already participate in the Medford CEA Program. Check your electricity bill to see if you’re one of them. In the Supply Services section, the Supplier should currently be listed as Dynegy – Medford for usage up until the December 2022 meter read, whereupon, the supplier name will change in January 2023 to NES – Medford Energy Aggregation once the renewal takes effect.

The Program will periodically send Customer Notification Letters to new or newly eligible electricity customers, which includes program details, information about product prices, and renewable energy. Customers who receive this letter and choose to participate will be automatically enrolled. To enroll sooner, use our online forms.

Future savings cannot be guaranteed because Basic Service rates change every six months for residential and commercial customers and every three months for industrial customers.

Products described as Green contain additional Renewable Energy Certificates (RECs) above that required by MA law. The additional RECs qualify for MA Class I designation and come only from solar, wind, anaerobic digestion and low impact hydro. Local means 100% of the additional RECs are sourced from New England.

Goals of Medford CEA

Competitive, Stable Price

Using strategic purchasing, combined with the bulk purchasing power of thousands of households and businesses in the Program, Medford Community Electricity Aggregation provides competitive, stable rates, though savings compared to utility Basic Service cannot be guaranteed.

Support Renewable Energy Sources

Medford CEA’s standard and optional products include more renewable energy than required by Massachusetts. This means you can use cleaner electricity and support the growth of renewable energy generation in our region.

Increased Choice and Easy Participation

The Program offers different options for electricity supply so that everyone in Medford can find an option that fits their budget and climate goals.

Participants in Medford CEA may leave the Program at any time without penalty.

How It Works

Medford CEA does not replace National Grid or Eversource as your electric utility. Your utility will continue to deliver electricity, repair outages and manage all billing. The Program offers alternatives for the Supply portion of your bill. See the Understanding Your Bill section on National Grid’s or Eversource’s websites to see the difference between Supply and Delivery sections.

The Program is open to electricity customers in Medford, whether they be a resident, business, renter, or owner. 

The Program has voluntary participation and automatic enrollment.

  • Voluntary participation: customers can leave the Program at any time without penalty.
  • Automatic enrollment for new customers: In Medford, most residential and business customers are already enrolled in the Program. New customers or newly eligible customers will periodically be sent a Customer Notification Letter notifying them of their choice to participate in the Program or leave before it starts (opt out). Customers have 30 days to make a choice and those who do not opt out are automatically enrolled in the Program. To enroll sooner, use our online forms.
  • Opt-in required for some: Those Medford residents and businesses who have already chosen an electricity supplier other than National Grid or Eversource will not receive the Customer Notification Letter, though they can voluntarily opt in to the Program at any time. The Department of Public Utilities advises all customers of third party suppliers to check their contract terms as their supplier may charge them a fee or a penalty to leave before the end of their contract with their supplier. 

Solar electricity consumers will not be impacted and will continue to receive all net metering credits while participating in the Program.

Budget Billing and Low Income Delivery Rate customers will continue to receive those benefits while participating in the Program.
