Marlborough Community Choice Power / Municipal Aggregation

Learn more about the City's electric supply program

The City of Marlborough, through its broker Colonial Power, periodically solicits bids for electricty supply. The rate consumers are charged for supply services makes up a portion of your electricity bill. By aggregating Marlborough's customers, we are able to secure lower rates for supply than a single customer may be able to do on their own. Below is a set of documents related to Marlborough's Community Choice Power Supply Program.

UPDATE August 2020: Participants in the Municipal Aggregation Program will receive this postcard in August 2020 informing them of the new rate change and term of contract.
