Southbridge Community Electricity is a program offered by the Town of Southbridge to provide residents and businesses more electricity supply options and more renewable energy. The program is a town-vetted alternative to National Grid default supply and other third-party electricity suppliers.
More Ways to Save! Anyone can get a lower supply rate through Southbridge Basic. Discounts are available if you are a low-income customer. Last year National Grid provided customers options to reduce your bill using heat pump discounts. This year, National Grid is lowering its heat pump rates further, effective November 1.

Future savings cannot be guaranteed. The additional Renewable Energy Certificates (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.

Please note: Customers that opt-out of the program and then seek to re-join, as well as new medium, large and very large business customers joining the program, may be offered a market price, rather than the program price shown in the table above. Such market price will be offered by the electricity supplier in writing, and you will not be enrolled in that price unless you affirmatively accept. The market price will be based on current wholesale prices and the supplier’s costs at the time the you seek to enroll, and the price will be fixed for the remainder of the Town’s contract with the supplier. At the start of the Town’s next supply contract, you will be transferred to the then-current program pricing.
