Please note: Prices for all options in the Rockland Community Electricity Aggregation (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. Program prices apply only to the electricity supply portion of your National Grid electric bill. Delivery charges on your National Grid electric bill are not affected by the CEA program.

National Grid’s fixed Basic Service rates change every six months for residential and commercial accounts and every three months industrial accounts.  Future savings compared to National Grid 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.
