Disclaimer: A goal of the aggregation program is to produce average savings over the full term of the Program, and price stability for customers, though 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 Commercial customers.

Program rates will be in effect from December 2022 to December 2024.
National Grid Basic Service rates change on May 1 and November 1 for Residential and Small Commercial accounts, and February 1, May 1, August 1 and November 1 for Large Commercial accounts.
