Signing up for Service

Customers moving in to PSEG Long Island service territory should be sure to call the company's customer service line at least 3 business days in advance to ensure that service begins in time. You can also turn on service in person at your local PSEG Long Island office.

PSEG Long Island service territory includes cities like Hampstead, Huntington, Islip, and more cities across Queens, Nassau, and Suffolk counties.

You will need to provide the following information to open a new account with PSEG Long Island:

  • Social security or passport number
  • New Address
  • Planned move-in date
  • Telephone Number

PSEG Long Island's main customer service line can be reached at 1-800-436-PSEG (7734) from 8:00 AM to 8:00 PM, Monday through Friday.

How to Choose an ESCO

PSEG Long Island is your local utility, which means they are your automatic provider of electricity service. This includes:

  • Delivery, or all costs related to getting energy to your home
  • Supply, or the cost of the actual energy you consume + customer service charges

If you choose an alternate Energy Supply Company (ESCO) you can save on your supply charges. You will need to open your PSEG Long Island account before shopping around for an ESCO plan, since the ESCO will need your account information to take over supply service.

We recommend fixed rate plans across the board, because they offer more stability. These plans come with contracts, so you should be aware of common contract conditions before signing up.

Learn more about what an ESCO does.

Terminating your Service

If you are moving out of PSEG Long Island territory, you will need to call customer service or visit in person at least 3 business days in advance of your move, to be sure that you are not billed for extra days. 

In order to cancel your ESCO contract, you will not need to take any extra steps.

However, to avoid paying an early cancellation fee, you will need to contact your ESCO usually around 30 days in advance. Check your contract conditions to know your plan's specifics.

Understanding your Bill

Your PSEG Long Island bill is divided up by supplydelivery, and state and local taxes. Most residential customers are classified under the SC1 rate category.

The New York Public Service Commission (NYPSC) regulates your PSEG Long Island charges - which means that all rate increases have been approved by NYPSC.
