NPRR1146  Credit Changes to Appropriately Reflect TAO Exposure

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.
