PSEG We make things work for you

Supplier Registration

PSEG has a number of web based tools to enhance our communications with our supplier base.

Potential Suppliers Registration


PSEG encourages potential suppliers to register their business on the PSEG Supplier Management System.  Registering your business on our website will ensure all PSEG buyers have detailed and accurate information about your business to make informed buying decisions.  Completing a supplier profile on the PSEG Supplier Management System is the first step to doing business with PSEG. 

Please create a supplier profile in the PSEG system or to update an existing profile.

Registration for Current/Active Suppliers


Welcome to the PSEG family of suppliers.

As an important part of PSEG’s continuing efforts to improve supplier relationships, PSEG requires all current/active PSEG suppliers register their business our new Supplier Certification Portal hosted by Dun & Bradstreet (D&B).  This will ensure PSEG meets mandated compliance requirements regarding Supplier authentication and verification while also giving suppliers the ability to update or establish a D&B profile.

All companies must have a D&B D-U-N-S Number to register. If you are not sure of your D‑U‑N‑S number or do not have one, you will be prompted to search for an existing D-U-N-S Number assignment. If you are unable to locate the D-U-N-S number, you will be provided with instructions on how to obtain one.


Current suppliers should have received an email notification with a user id and password.  There is a nominal feel for this registration, and it is payable online via credit card.

If you are a current PSEG supplier and have a user id and password, please log in here: 

Otherwise, If you have questions or need assistance with the registration process, please contact D&B Customer Support at the following numbers:

  • United States: (866)322-2761
  • Outside the United States: (866)322-4685

Tier II Reporting


PSEG's Tier II Supplier Diversity Process has been established to encourage the use of minority and women business owners by our prime suppliers. This use includes subcontracting and the acquisition of materials or services from diverse suppliers which add to the value of the product purchased by PSEG. The policy on Tier II suppliers supplements PSEG's overall supplier diversity efforts. Under this initiative, all prime suppliers who have a Tier II process will be viewed as supporting and adding value to the Supplier Diversity process at PSEG.

On a quarterly basis, PSEG suppliers are requested to report their Tier II Diverse Spend electronically to the Office of Supplier Diversity. This data is due by the 15th of the month following each calendar quarter. Our online reporting system allows suppliers to quickly and easily report their direct and indirect spend with diverse-owned suppliers in support of their work for PSEG.
