Overview

Medfield Community Electricity (MCE) is the Program offered by the Town with new electricity supply options that provide more renewable energy and stable prices for all Medfield residents and businesses. The program is a town-vetted alternative to Eversource’s default supply and other third party electricity suppliers.

The MCE program has been active for a year! Check out this presentation on the programs first year.

Anyone can get a lower supplier rate through Medfield Basic. Discounts are available if you are a low-income customer. You can also reduce your bill through heat pump discounts. Learn more below.

Participants in the Program will automatically receive Medfield Standard, the program default, unless one of the other optional products is selected. To choose a different product, click here.

Future savings cannot be guaranteed. The additional RECs qualify for MA Class I designation and come only from solar, wind, anaerobic digestion and low impact hydro. RECs are the accepted legal instrument used to track renewable energy generation and to substantiate claims of renewable energy use.

    • Estimated savings: About $540 per winter (Mass. DPU).
    • No impact on supply: Only affects delivery charges; aggregation supply rates stay the same.
    • Non-heat-pump customers: Remain on standard delivery rates.
    • Enrollment notices: Will be sent prior to the November 1, 2025 enrollment date.
    • Manual enrollment: All other customers need to reach out to Eversource to enroll.
