Northbridge Electricity Program

In early 2016, the Town of Northbridge joined 22 other communities to launch a community electricity aggregation (CEA) program designed to provide residents and businesses with competitive choice, long-term price stability, and reduced electricity rates. Also known as municipal electricity aggregation, the program relies on bulk-purchasing methods that generate economies of scale, resulting in reduced electricity supply costs for participating National Grid account holders. 

The program has since renewed with Public Power, LLC and will run for 36 months beginning September 2018 through January 2021 at a rate of 10.430 cents/kWh. See rates below.

Disclaimer: A goal of the CEA program is to produce savings for customers, but savings cannot be guaranteed compared to the utility’s basic service rate which changes every six months for Residential and Small Commercial customers, and every three months for Large Commercial customers. The aggregation program seeks to provide price stability and average savings over the full term of the program, but because future basic service rates are not known, there is no guarantee of savings.

Only the supply portion of your National Grid bill will be impacted. National Grid will continue to deliver your power as it has done in the past, but Public Power, LLC will be indicated as the supplier of record on the supply portion of your National Grid bill beginning in January 2018. There will be no change in the level of service you receive from National Grid as a result of participating in the Northbridge program.

How to enroll
Enrollment occurs automatically. National Grid account holders that are not currently participating will receive an opt-out letter detailing the program and providing answers to most commonly asked questions. This letter will also provide simple instructions on how to opt out (not participate) of the program.

For those moving to or within Northbridge, you may proactively contact the program supplier, Public Power, LLC, to re-enroll/enroll your new account in the aggregation program at the original rate for the duration of the term, ending January 2021. If you do not proactively contact Public Power, you will receive an opt-out notification letter detailing the program. Simply disregard the opt-out notification letter if you wish to participate in the program. Please note that your first month of service will default to National Grid Basic Service supply, but will then transition to the Northbridge program on your next available billing cycle.

Account holders that are currently under contract with a third party supplier will not receive an opt-out letter and will not be auto-enrolled in the program, however, these account holders may opt in by contacting Public Power, LLC.
Please note: account holders currently on with a third party supplier should review the terms & conditions of their existing supply contract for any early termination fees associated with ending their existing supply contract prior to opting into the Northbridge program.

How to opt out or discontinue participation
If you do not wish to participate, simply send back the self-addressed postage-paid card enclosed in the opt-out letter within 30 days of the letter’s postmark or contact the program supplier, Public Power, LLC, directly. You may also opt out of the program here.
