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!

More Ways to Save!

In addition to the supply options through the program, discounts are available for low income customers and customers with heat pumps. Learn more below.

Program Options

Are you participating in the Program? You can check if you participate and your supply option price by looking in the Supply Section of your National Grid or Eversource bill. Join the program or change your option at any time here. Compare costs with our calculator (National Grid) or Eversource.

Future savings compared to Eversource Basic Service cannot be guaranteed because future Basic Service prices change every six months for residential and commercial customers and every three months for industrial customers.

The additional RECs qualify for MA Class I designation and come only from solar, wind, anaerobic digestion and low impact hydro. RECs are the accepted legal instrument used to track renewable energy generation and to substantiate claims of renewable energy use. Learn more about the product details and renewable energy content here.

Please note: Customers that opt-out of the program and then seek to re-join, as well as new medium, large and very large business customers joining the program, may be offered a market price, rather than the program price shown in the table above. Such market price will be offered by the electricity supplier in writing, and you will not be enrolled in that price unless you affirmatively accept. The market price will be based on current  wholesale prices and the supplier’s costs at the time the you seek to enroll, and the price will be fixed for the remainder of the City’s contract with the supplier. At the start of the City’s next supply contract, you will be transferred to the then-current program pricing.

More Ways to Save Today

• Low-Income Discount: National Grid in Massachusetts has transitioned to a tiered low-income discount rate, replacing the previous flat 32% discount. Discounts now range from 32% to 71% based on income level and apply to the entire bill, including the cost of Medford Community Electricity Aggregation (CEA) supply. Go to this page to enroll. Eversource in Massachusetts provides a 42% discount to low-income customers that apply to the entire bill too. Go to this page to enroll. 
• Heat Pump Discount Rate: Beginning November 2025, most electricity customers with heat pumps will receive a discount through a new “heat pump” delivery rate offered by their electric utility – either National Grid or Eversource. This discount applies only to the delivery portion of electric bills, so customers in this community’s aggregation program remain eligible and can enjoy added savings.
  • Key details:
    • Most customers with qualifying heat pumps will be automatically enrolled in this rate.
    • The rate applies during the winter season (November 1 – April 30) each year.
    • The new rate lowers delivery costs but does not affect aggregation supply rates.
    • According to the Massachusetts DPU, households on the new rate could save around $540 over the winter.
    • There is no conflict between the new delivery rate and your aggregation program’s supply prices – the two are complementary in helping customers manage costs.
  • Eligibility and enrollment:
    • National Grid customers: Homes with a Mass Save®-supported heat pump installed on or after January 1, 2019 on a residential electric account will be automatically enrolled starting November 1, 2025. Customers not automatically enrolled may still qualify and can apply at the end of October 2025 via National Grid’s Heat Pump Rate page.
    • Eversource customers: Homes that received a Mass Save® rebate through their Eversource electric account for a heat pump installed after January 1, 2019 will also be automatically enrolled starting November 1, 2025. Those who installed a system before that date or did not receive a rebate may apply now on Eversource’s Heat Pump Rate page. Customers using electric resistance heating (baseboards, space heaters, or furnaces) do not qualify.
