How to Choose an ESCO

As your local utility company, National Grid responsible for delivering electricity to your home. They are also the default electricity and natural gas supplier in the areas they serve. But did you know that you have a choice of energy supplier? Alternate Energy Supply Companies (ESCOs) offer you a wider range of price and payment options, including some great deals

Terminating Service

If you are moving out of National Grid territory, you will need to call customer service or notify National Grid online at least seven (7) days in advance of your move, to be sure that you are not billed for extra days. For natural gas customers, a technician may need to come to your home to get an accurate final meter reading.

If you purchase energy from an ESCO, we recommend contacting them at least 30 days in advance in order to avoid paying an early cancellation fee. Check your contract conditions to know your plan's specifics.

Understanding Your Bill

Your National Grid bill is divided up by supply, delivery, and state and local taxes. Most residential customers are classified under the SC1 rate category.

The New York Public Service Commission (NYPSC) regulates your National Grid charges, which means that all rate increases are approved by NYPSC as fair.
