Please note: Prices for all options in the Waltham Community Electricity program include a $0.001 /kWh administration fee. Program prices could increase as a result of a change in law that results in a direct, material increase in costs during the term of the electricity supply agreement. Program prices apply only to the electricity supply portion of your Eversource electric bill. Delivery charges on your Eversource electric bill are not affected by the WCE program.

Eversource’s fixed Basic Service rates change every six months for residential and commercial accounts and every three months industrial accounts.  Future savings compared to Eversource Basic Service cannot be guaranteed because future Basic Service prices change every six months for residential and commercial customers and every three months for industrial customers.

MA CLASS I RECs

The optional products Waltham 50 and Waltham 100 contain an amount of RECs above that required by the Commonwealth. The additional RECs qualify for MA Class I designation and include generation from solar, wind, anaerobic digestion, or low-impact hydro located within New England.
