As defined in the new TOD rate schedule:

• Peak: weekdays 3:00 p.m. to 7:00 p.m.
• Super Off-Peak: every day from 1:00 a.m. to 5:00 a.m.
• Off-peak: All other hours

Monday through Friday 5:00 a.m. to 3:00 p.m. and 7:00 p.m. to 1:00 a.m.

Saturday and Sunday 5:00 a.m. to 1:00 a.m.

On weekdays there are three time periods: Peak, Super Off-Peak and Off-peak. 

On weekends there are only two time periods: Super Off-Peak and Off-peak. 

Those hours that are Peak on weekdays will be considered Off-Peak on the weekends. 

We also apply seasonal charges during the shoulder months of March, April, October, and November.

Holiday rates remain unchanged.

The TOD rate is being rolled out in phases. In the first phase, there isn’t as much variation in the peak period prices. However, in phase two, the differences will widen further; creating a wider differential between the Super Off-Peak and the Off-Peak price. It will be helpful to get accustomed to maximizing Super Off-Peak use via flexible loads in phase one so that you can realize bigger savings in phase two.

CMLP's residential rates are about 30% lower than those customers who live in investor-owned utility areas served by National Grid, Eversource, and Unitil. Our residential rates, however, are higher than those of other municipal utilities because of deliberate local choices to invest in programs and services that directly benefit our customers and community.

CMLP’s energy supply is 100% carbon-free. Not many Massachusetts light plants can claim this.

CMLP offers a wide range of programs and incentives that are not always available—or as robust—from other providers. These include incentives and support for solar installations, heat pumps, electric vehicles and chargers, weatherization and energy efficiency upgrades, and other customer-focused programs. These investments help customers reduce long-term energy costs, lower emissions, and improve comfort and reliability.

In addition, CMLP maintains local control, high reliability standards, and responsive customer service, with decisions made by and for the community rather than by shareholders.

While the price per kilowatt-hour is an important consideration, many customers find that the overall value—including rebates, incentives, energy savings, and local service—makes CMLP’s rates competitive when viewed over time.

We encourage customers to consider both rates and available programs when comparing electric service options.

CMLP staff, often under the oversight of a third party rate expert, recommends rate adjustments, when needed, to CMLP’s governing board. With consideration of input from the community, the governing board determines rates. The decision to adjust rates is based on factors such as changes in wholesale electricity costs, infrastructure investments, and overall financial health of the utility.

The amount of any rate adjustment is proposed by CMLP staff based on a thorough analysis of costs and revenue requirements. The proposal is then reviewed and approved or adjusted by the CMLP governing board. Public meetings are held to ensure transparency and allow for community feedback before any changes are finalized.
