Program Details

Charlton has renewed its Community Electricity Aggregation (CEA) Program, with new prices starting in December 2022. If you participate in Charlton CEA Standard, no action is necessary to receive the new rates (most residents and businesses participate in this option). You will automatically receive the new pricing as of December 2022.

Charlton Community Electricity Aggregation (CEA) is an electricity supply program organized by the town of Charlton to provide residents and businesses with new, Town-vetted options for electricity supply. The delivery of electricity and billing for use is still completed through National Grid, so customers continue to receive one bill from the utility.

Program Products

Charlton CEA has a standard product, called Charlton Standard. Participants in the Program receive Charlton Standard unless they affirmatively choose the 100% renewable energy product called Charlton 100% Local Green.

How to Participate in Charlton CEA

Most residents and businesses in Charlton already participate in the Charlton CEA Program. Check your electricity bill to see if you’re one of them; the Supplier will be listed as Direct Energy – CharltonCEA. If National Grid is still listed as your supplier, you may complete the enrollment form to sign up for Charlton CEA.

Participation in the Charlton CEA Program is voluntary; you can leave the Program at any time without fee or penalty.

The Program will periodically send Customer Notification letters to new or newly eligible electricity customers, which includes program details, information about product prices, and renewable energy certificates.
