PROGRAM NEWS: Chelmsford Choice prices changing in November

Chelmsford currently has a contract with Constellation to supply electricity to Chelmsford Choice participants. That contract will expire in November of this year, and a new, 24-month contract with Dynegy will go into effect. The new contract will bring new prices.

The Constellation contract was signed in 2020 and has kept our prices low. However, electricity supply prices have risen significantly since then because of volatility in global energy markets. Chelmsford Choice prices will move to market levels when the Dynegy contract takes effect. The new prices are:

  • Chelmsford Choice Basic: 14.843 ¢/kWh
  • Chelmsford Choice Greener – 16.415 ¢/kWh
  • Chelmsford Choice Greenest – 17.849 ¢/kWh

While all program prices will be higher than current prices, they will be lower than National Grid’s upcoming residential Basic Service price, which will take effect on November 1. Please note that because National Grid’s prices change and future prices are not known, future savings compared with National Grid cannot be guaranteed.

Chelmsford Choice is a Town electricity aggregation program that gives Chelmsford residents and businesses a Town alternative to other electricity supply offers in the marketplace, without high pressure or fees. For participants, the program changes the price that is used to calculate the Supply Services charge on their National Grid electric bills.

The program offers consumer protections and the potential for savings (though savings cannot be guaranteed), while also helping to support Chelmsford’s sustainability efforts.

Three consumer-friendly electricity choices

As a new participant in Chelmsford Choice, you will be automatically enrolled in the Chelmsford Choice Basic option for 14.843 ¢/kWh. If you want more clean electricity from renewable sources like the sun and the wind, you can choose from two additional options, Chelmsford Choice Greener and Chelmsford Choice Greenest.

How it works

A municipal electricity aggregation is a group electricity purchasing program. Participating in Chelmsford Choice will change your electricity supplier and the price National Grid uses to calculate the Supply Services portion of your electric bill, but participating will not replace National Grid as your electric utility. How aggregation works.

Savings cannot be guaranteed

Please note that, while Chelmsford Choice offers the potential for savings when compared with National Grid’s Basic Service price, there is no guarantee of savings. This is because National Grid’s prices change every 6 months for residential and small business customers and every 3 months for large business customers and future National Grid prices are unknown.

Protect your National Grid account number

National Grid will never knock on your door or call you to talk about your electric bill.
Only provide your National Grid account number if you are ready to change your electricity supplier.
