Disclaimer: A goal of the aggregation program is to produce savings for customers, but savings cannot be guaranteed compared to the utility’s basic service rate which changes every six months for Residential and Small Commercial customers and every three months for Large Business 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 2023 to December 2025.
National Grid Basic Service rates change on May 1 and November 1 for Residential and Commercial accounts, and February 1, May 1, August 1 and November 1 for Industrial accounts.
