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.
