Program Details

The Town of Charlton launched the Charlton Community Electricity Aggregation (CEA) program for residents and businesses in July 2017. The primary goals of the program are to provide annual savings and rate stability for participating consumers. The program was approved by the Board of Selectmen and the Massachusetts Department of Public Utilities.

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 Industrial 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.
