Welcome to Nantucket PowerChoice, a local Town electricity program. Nantucket PowerChoice offers Nantucket residents and business long-term electricity price stability, consumer protections, and the potential for savings (though savings cannot be guaranteed).

In addition, Nantucket PowerChoice directly supports the development of new renewable energy projects on Nantucket through the Nantucket Local Solar Rebate Program.

By helping to build new solar projects on Nantucket, you help to reduce Nantucket’s reliance on fossil fuels during peak electricity use periods, which can bring down electricity costs for everyone.

Two consumer-friendly electricity options

You may choose between two options in Nantucket PowerChoice for greater control over the price and environmental characteristics of your electricity supply. Both options offer transparent pricing, no hidden fees, and the ability to leave the program at any time. Your participation in either option includes a fee of $0.001/kWh to support the Nantucket Local Solar Rebate Program.

For 100% renewable electricity, opt up to the PowerChoice Green option online or by contacting customer support with the Town’s program consultants.

How it works

A municipal electricity aggregation is a group electricity purchasing program. Participating in Nantucket PowerChoice 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.

Understand your bill

Nantucket PowerChoice is integrated into your existing National Grid electricity bill. You can use your National Grid bill to learn if you are enrolled in the program and in which option you are enrolled.

Savings cannot be guaranteed

Please note that, while Nantucket PowerChoice 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.
