Frequently Asked Questions

Massachusetts customers have two separate accounts for their gas and electric service, with two separate logins. Electric accounts require an email address to login, gas account require a username to login. We realize this is a source of some confusion, and we are exploring long-term solutions to unite the accounts, but in the meantime you will need to log into each account separately.


If you are on the Massachusetts Gas site and want to switch to the Electric site, click on the “Gas” link in the top left corner of our site and select "Electric" instead. If you're using a mobile device, click on the "Change Location" link in the top left corner of your screen and select Massachusetts as your region and then select Electric. 

To access your gas bill:
