Reliant Energy login : "My Account" bill pay for residential customers

Residential customers can use the Reliant Energy login and account management features available in the My Account section of the Reliant Energy website.

Reliant Energy makes the My Account sign-up process quite simple. All customers need to do is provide their 9-digit Reliant Energy account number to get started.

Where is my Reliant Energy account number?

The account number can be found on the top right corner of the electricity bill. If an electricity bill can´t be found, customers can also find their Reliant Energy account number on the Weekly Summary email and the Bill Reminder email that is sent out by Reliant.

Can I sign up with the Reliant Energy login without my account number?

Yes! For customers that cannot locate their Reliant Energy account number in the three places mentioned above, all that's needed is:

  1. to specify the customer type: Residential, Business, Sole proprietorship, or "other"
  2. Last name (surname) on the account
  3. the service address, street number (exclude the street name)
  4. the account holder's date of birth (mm/dd/yyy)
