Description: This Nodal Protocol Revision Request (NPRR) makes changes to credit provisions related to Trading Activity Only (TAO) Qualified Scheduling Entities (QSEs) that appropriately reflect their credit exposure. Specific changes include: eliminating the Unbilled Real-Time Amount (URTA) for TAO QSEs; allowing TAO QSEs to request an M1 of about two days by agreeing to certain conditions including suspending Real-Time Market activities upon ERCOT notice (Day-Ahead Market activity is systematically restricted to Available Credit Limit); clarifying that a TAO QSE is a QSE that does not represent either Load Serving Entities (LSEs) or Resource Entities, thus ensuring that a QSE engaging exclusively in DC Tie exports and other trading activities will be classified as a TAO QSE; and determining Counter-Party’s Total Potential Exposure (TPE) by adding the separate credit calculations for the Counter-Party’s (i) QSEs that represent LSEs or Resource Entities, (ii) TAO QSEs that do not represent LSEs or Resource Entities, and (iii) Congestion Revenue Right (CRR) Account Holders.
Reason: Market efficiencies or enhancements
