Please note: 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 Charlton Community Electricity Aggregation (CEA) program.
Prices for all options in the Charlton 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 against National Grid’s fixed Basic Service rate cannot be guaranteed because National Grid’s rates change every six months for residential and commercial customers and every three months for industrial customers.
