Wareham CEA details

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 has been renewed for an additional term through Fall 2025. The Town will announce the program rates this Fall and take effect on the December 2023 meter read. All current participants will receive a notice in the mail about a month before the new rates take effect. View December 2023 Prices here.

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.
