Registration Information

Pursuant to the ERCOT Protocols, ERCOT has ten (10) Business Days to approve or reject an LSE application for registration once it has been submitted and deemed complete. In order to ensure that ERCOT has adequate time to evaluate an application, any new CR wishing to participate in an upcoming retail market test flight should undertake the below-referenced steps at least ten (10) Business Days before the Application Processing Deadline indicated above. Failure to do so could render the CR ineligible for the upcoming flight.

The following steps must be completed by any new CR wishing to participate in an upcoming retail market test flight, and processed by ERCOT, before the Application Processing Deadline:

  • Apply for and receive a Data Universal Numbering System (DUNS) number that is accessible by ERCOT on www.dnb.com (Note: ERCOT must be able to view and access the DUNS Number through www.dnb.com by the Application Processing Deadline; merely obtaining a DUNS Number from Dun and Bradstreet the day of the Application Processing Deadline is not sufficient, as it may take Dun and Bradstreet several days to enter the DUNS Number into their system); 
  • Submit an LSE registration form and the appropriate application fee to ERCOT;
  • If registering as a Retail Electric Provider (REP), apply for REP certification with the Public Utility Commission of Texas; and
  • For more information, send an e-mail to RetailMarketTesting@ercot.com.
