Southborough Community Power Choice is a Town electricity aggregation program that gives Southborough residents and businesses a Town-vetted alternative to National Grid’s Basic Service and other electricity supply offers in the marketplace, consumer protections, and the potential for savings compared with National Grid’s Basic Service price (though savings cannot be guaranteed).

Two consumer-friendly electricity options

You may choose between two options in Southborough Community Power Choice. Both options offer transparent pricing, no hidden fees, and the ability to leave the program at any time.

How it works

A municipal electricity aggregation is a group electricity purchasing program. Participating in Southborough Community Power Choice will change your electricity supplier and the price National Grid uses to calculate the supply 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 Southborough Community 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 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.
