Community Choice Aggregation Program

The Town of Carlisle is pleased to provide a Community Choice Aggregation Program (aka, Community Choice Power Supply or Municipal Aggregation) (“Program”). This Program enables local government to combine the purchasing power of its residents and businesses to provide them with an alternative to Eversource Basic Service (M.G.L. c. 164, § 134). This Program only affects the supply portion of a participant’s monthly bill. It does not affect the delivery portion of a participant’s monthly bill. Eversource delivers electricity throughout Carlisle regardless of supplier, but Carlisle chooses the supplier for the Program. Each time Carlisle initiates a new supply contract, the new supplier will provide electric power supply for all consumers currently on Eversource Basic Service in Carlisle, unless they have previously opted out of the Program.  Consumers can opt out of, or into, the Program at any time.  However, consumers using independent suppliers may face penalties if they change suppliers before their existing contracts end.
