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 electricity 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 10.042 ¢/kWh. If you want more clean electricity from renewable sources like the sun and the wind, you can choose from two additional options: The Chelmsford Choice Greener option provides a total of 62% clean, renewable electricity for 11.484 ¢/kWh. The Chelmsford Choice Greenest option provides all (100%) of your electricity from clean, renewable sources for 13.015 ¢/kWh.

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 supplier services portion of your electricity 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 electricity bill.
Only provide your National Grid account number if you are ready to change your electricity supplier.
