LONG DESCRIPTION: ERCOT, the Texas SET Working Group, and the Market Coordination Team (MCT) would like to announce that preparations are underway for the next round of Retail Market Qualification Testing, Flight 0924. Flight 0924 will test for TX SET Version 5.0, and is scheduled to begin on Tuesday, August 6, 2024. Testing will be completed in the FlighTrak system.     

Testing for the TX SET V5.0 upgrade, developed pursuant to ERCOT Protocol 19.8, is required for all CRs and TDSPs that wish to remain eligible to serve customers in the ERCOT Market.

Testing is required for:

•           new Market Participants (CRs and TDSPs) entering the Texas Retail Market,

•           existing Market Participants (CRs and TDSPs),

•           entering new service territories,

•           testing additional business functionality,

•           changing service providers,

•           changing banking information, or

•           adding another entity to their business umbrella.

Market Participant business names should coincide between ERCOT registration, Public Utility Commission of Texas (PUCT), and Texas Secretary of State. Discrepancies in these names will delay ERCOT’s ability to generate qualification letters after testing is complete.

Out of Flight testing includes testing for changing service providers to an existing service provider and changing banking information but is not an option for qualification on the TX SET 5.0 standard.
