Program Details

Medford Community Electricity Aggregation (CEA) is a program offered by the City of Medford’s Office of Planning, Development, and Sustainability to provide new electricity supply options and more renewable energy to Medford residents and businesses. The program doesn’t replace National Grid, the electric utility in Medford, which still continues to deliver electricity, repair outages, and manage all billing, so 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!

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 NES – Medford Energy Aggregation.

The Program will periodically send Customer Notification Letters to new or newly eligible electricity customers, which includes program details, including 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.

Medford CEA has a standard product, called Medford Local Green, which has more renewable energy than required by Massachusetts. Participants in the Program receive Medford Local Green unless they affirmatively choose one of the other electricity products.

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

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.
