Program Details

The Town of Sudbury launched the Sudbury Community Electricity Aggregation  program for residents and businesses in August 2017. The primary goals of the program are to provide a cost-effective, stable and responsible alternative to utility electricity rates for participating consumers. However, the program also offers participants exciting renewable energy options from which to choose. The program was approved by the Board of Selectmen and the Massachusetts Department of Public Utilities.

Below is a chart comparing the rates for the Sudbury Community Electricity Aggregation program to Eversource’s winter 2020 rates.

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.
