Westborough Power Choice is a Town electricity aggregation program, which is a kind of group electricity buying program.

The program gives Westborough residents and businesses an alternative to National Grid’s Basic Service and other electricity supply offers in the marketplace without high pressure or fees. The program impacts the supply services portion of each participant’s electricity bill.

Through the program, electricity customers in Westborough receive more renewable electricity, long-term stable prices, consumer protections, and the potential for savings (though savings cannot be guaranteed). The additional renewable electricity added by Westborough comes through the purchase of renewable energy certificates (RECs) from Massachusetts Class I-eligible systems.

New electricity accounts in Westborough will be eligible for automatic enrollment in accordance with State law and will receive a letter in the mail from the Town prior to enrollment.

Cleaner electricity and consumer-friendly choices

As a new participant in Westborough Power Choice, you will be automatically enrolled in the Standard plan and receive 42% of your electricity from premium renewable sources in New England, which include 22% required by state law and another 20% added voluntarily by Westborough. You also have two additional choices: the 100% Green plan for 100% clean, renewable electricity, and the Budget plan for only the minimum amount of renewable electricity required by state law.

How it works

A municipal electricity aggregation is a group electricity purchasing program. Participating in Westborough Power 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.

Savings cannot be guaranteed

Please note that, while Westborough Power 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 commercial customers and every 3 months for industrial 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.
