Please note: program prices apply only to the electricity supply portion of your Unitil electric bill. Delivery charges on your Unitil electric bill are not affected by the Fitchburg Community Electricity Aggregation (CEA) Program.

Prices for all options in the Fitchburg CEA 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.

Future savings compared to Unitil Basic Service cannot be guaranteed because future Basic Service prices change every seven months for residential and commercial customers, and every three months for large commercial customers.


Products described as Green 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.
