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 December 2018 to December 2020.  
National Grid Basic Service rates change on May 1 and November 1 for Residential and Small Business & Lighting accounts, and February 1, May 1, August 1 and November 1 for Large Business accounts.
