The City of Marlborough, through its broker Colonial Power, periodically solicits bids for electricity 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.

The City has signed a contract with First Point Power with a rate of $0.14919 per kilowatt-hour (kWh). This is a 100% wind Renewable Energy Credits - 100% renewable energy green product. This rate is in effect from March 2026 to November 2028.

• National Grid’s basic service rate of $0.15372 per kWh and meets Massachusetts renewable energy requirements.  This rate is in effect from February 2026 to July 2026.
