In 2019, the Town of Wareham launched its Wareham Community Electricity Aggregation (CEA) program designed to provide residents and businesses with competitive choice and long-term price stability, understanding that future savings cannot be guaranteed because future Eversource Basic Service rates are unknown.

Wareham CEA program rates

The aggregation programs for all municipalities participating in the MASSCEA buying group have been renewed for an additional term through late fall 2025. New pricing, shown below, will go into effect starting December 2023. The programs’ supplier will remain Constellation.

Most customers do not need to take any action to receive the new pricing. However, due to requirements from the Department of Public Utilities, customers currently in the 50% or 100% Green products must affirmatively re-enroll or their accounts will be returned to Basic Service.

To re-enroll we recommend submitting a request through the enroll form below. Alternatively you can contacting the supplier, Constellation, at (833) 461-0813.

In addition to the standard electricity supply product, the Program also offers an option with 100% total energy from renewable energy certificates. You can sign up for either option, return to the default or leave the program at any time. You can also check the sample bill for an illustration of a simple way to tell if you a part of the CEA program.

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 change 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.

All of the additional RECs included in the program are designated as Massachusetts Class I. RECs are the accepted legal instrument used to track renewable energy generation and to substantiate claims of renewable energy use.
