Duquesne Light accepts payments and sends bills through Electronic Data Interchange (EDI). If your business is EDI-ready, or if you're considering this business investment, read DLC's EDI Guidelines and then execute two originals of the EDI Trading Partner Agreement, available here or from your DLC Account Manager.

Upon execution of the agreement, a DLC representative will contact you to explain testing requirements and schedule a date for testing to begin. Following completion of all testing, your organization's bill will be switched to EDI.


Number of Accounts

This EDI billing/payment option is available to all customers with EDI capability who have at least 100 subordinate accounts. If you have less than 100 accounts with DLC, there are third party billing agents that you can contact.

EDI Software

If your organization does not already have EDI capability, you will need to purchase and install EDI translation software. The software must be capable of receiving the American National Standards Institute (ANSI) X-12 V4010, Utility Industry Group (UIG), Transaction Set 810 Invoice.

VAN Mailbox

You will need to establish an electronic mailbox with a Value Added Network Service Provider (VAN). You must have access to a VAN for EDI 810 invoices and EDI 820 payment/remittance orders.

Value Added Service Bank

You will need to contact your banking institution and verify that they provide services as a Value Added Service Bank. Your bank must be capable of providing electronic payments in one of two ways:

  • Remittance data per the American National Standards Institute (ANSI) X-12, Utility Industry Group (UIG) , 820 Payment and Remittance Order; or
  • National Automated Clearing House (ACH) payments in Corporate Trade Exchange (CTX) format.

If your banking institution does not provide services as a Value Added Service Bank, you or your bank will need to contact Mellon Bank, DLC's banking institution, for EDI to exchange any information and perform required setup.
