Program Details

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

Program Products

Are you participating in the program? Check your electricity bill to see if you’re one of them: the Supplier will be listed as Direct Energy – CharltonCEA. Join the program or change your option at any time here. Compare costs with our calculator here.

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 Town’s contract with the supplier. At the start of the Town’s next supply contract, you will be transferred to the then-current program pricing.

More Ways to Save

• 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 the Charlton CEA supply. Go to this page to enroll.
• Heat Pump Discount Rate: Starting November 1, 2025, most electricity customers with heat pumps will receive a discount through National Grid’s ‘heat pump’ delivery rate. 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. 
  • Automatic enrollment: Customers with Mass Save®-supported heat pumps installed on or after Jan 1, 2019 will be automatically enrolled starting Nov 1, 2025 — no action needed.
  • Winter discount: Reduced delivery rates apply Nov 1 – Apr 30 each year.
  • Estimated savings: About $540 per winter (Mass. DPU).
  • No impact on supply: Only affects delivery charges; aggregation supply rates stay the same.
  • Non-heat-pump customers: Remain on standard delivery rates.
  • Enrollment notices: Sent by late Oct 2025.
  • Manual enrollment: All other customers need to reach out to National Grid to enroll.
