Options & Pricing

New electricity customers in Nantucket will be automatically enrolled in the PowerChoice option. For 100% renewable electricity, you may opt up to PowerChoice Green for a small premium.

The Commonwealth of Massachusetts requires that all electricity supply products include a minimum of 49% from renewable energy resources in 2021, 51% in 2022, 59% in 2023, and 62% in 2024. PowerChoice meets the minimum requirement. PowerChoice Green exceeds that requirement. Participants in both PowerChoice and PowerChoice Green support the Nantucket Local Solar Rebate Program and the development of new residential solar electricity projects on Nantucket.

Nantucket PowerChoice prices are long-term prices, while National Grid’s Basic Service prices change frequently. The Nantucket PowerChoice goal is to provide value when compared with the average of National Grid’s changing prices, though savings can never be guaranteed.

Massachusetts minimum renewable energy requirements

The Massachusetts Renewable Energy Portfolio Standard (RPS) and Alternative Energy Portfolio Standard (APS) require all electricity suppliers to integrate a minimum amount of energy from specific renewable and alternative energy sources into the electricity supplied to their retail customers. The total required amount increases each year.

The minimum requirement for renewable electricity from new energy projects in the New England region (MA Class I RECs) is 18% in 2021, 20% in 2022, 22% in 2023, and 24% in 2024.

This requirement applies to National Grid and all electricity suppliers, including the electricity supplier serving Nantucket.

Renewable energy certificates

The Nantucket PowerChoice program purchases renewable energy certificates, or RECs, to integrate renewable energy into the Town’s electricity supply. In general, RECs are used to determine the environmental content of electricity. Each REC represents proof that 1 megawatt-hour of electricity was generated by a renewable energy resource.
