For those of you who are NSTAR (https://eversource.com) customers, you may be confused as to the new changeover to the company name Eversource. Especially if you happened to miss the announcement from NSTAR about the change, you may be wondering how you can now make payments on your energy bill through them. The processes are similar to when they were NSTAR, but the website does seem much easier to log in to for payments as well as an overall better presentation online.

If you would like to make a payment toward your account balance with Eversource, find the method below that you would like to use and submit your payment as described.

Option 1: Online Payments for Eversource (NSTAR)

To make an online payment for your Eversource account, you will need to first go through the company’s online registration page, which you can find by clicking here: https://eversource.com/Security/Account/Register. (this used to be the nstar.com pay bill area, which still exists but should not be used). On the registration page, you will need to enter your personal and account information as well as create your user ID and password to use for signing in to your account.

After you have the login account all set up and verified, you can head to the Eversource Log In page. Here, you will type in your user ID and password into the boxes labeled as such, then click the “LOG IN” button.
