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 by 1% every year. For 2020, it is 27.7056%. Within that, 16% must be from newer renewable energy projects in New England (Massachusetts Class I RECs).

This requirement applies to National Grid and also to any other electricity suppliers, such as Direct Energy, which is 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.
