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 Community Electricity Aggregation (CEA) program has been renewed, with new prices for the period November 2025 until November 2028. Current participants do not need to take any action to remain in the Wareham CEA program and receive the new pricing.

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.
