NOTICE TYPE: M-A021726-01 NPRR

SHORT DESCRIPTION: Implementation Details of NPRR1266, Opt-Out Status Held by a Transmission-Voltage Customer Cannot be Transferred

INTENDED AUDIENCE:  All Market Participants

DAYS AFFECTED: March 1, 2026

LONG DESCRIPTION: On March 1, 2026, Protocol language associated with Nodal Protocol Revision Request (NPRR) 1266, Opt-Out Status Held by a Transmission-Voltage Customer Cannot be Transferred, will be implemented.  

NPRR1266 adds a statement that a transmission-voltage Customer that is a Securitization Uplift Charge Opt-Out Entity may not transfer its status as a Securitization Uplift Charge Opt-Out Entity to other entities; and adds a requirement that a Transmission Service Provider (TSP) associated with an Electric Service Identifier (ESI ID) originally granted opt-out status must, on at least a monthly basis, compare the customer names of those transmission-voltage Customers originally granted opt-out status as of November 29, 2021, determine if any of the names associated with those ESI IDs have changed since that date, and inform ERCOT of any such changes identified. This TSP requirement excludes TSPs that are themselves Securitization Uplift Charge Opt-Out Entities.

Upon evaluating the monthly submissions by the application TSPs, ERCOT will notify the Public Utility Commission of Texas (PUCT) Staff and the Retail Electric Provider (REP) of record associated with any ESI IDs ERCOT has reason to believe reflect a changes of transmission-voltage Customer since November 29, 2021.  ERCOT will subsequently remove the ESI ID's status as an Opt-Out Customer and notify the REP of record associated with the ESI ID upon any finding by the PUCT that the original Customer is no longer associated with the Securitization Uplift Charge Opt-Out Entity's ESI ID.

ADDITIONAL INFORMATION:  Pursuant to Protocol Section 21.6, Nodal Protocol Revision Implementation, ERCOT is required to provide notice as soon as practicable, but no later than ten days prior to implementation.  

NPRR1266 and the associated documents can be found on the ERCOT website.
