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 three months for industrial customers and every six months for residential and small 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.

Program rates will be in effect from July 2017 to August 2020.  
Eversource Basic Service rates change on January 1 and July 1 for Residential and Small Business & Street Lighting accounts, and January 1, April 1, July 1 and October 1 for Large Business accounts.
