Description: This Nodal Protocol Revision Request (NPRR) revises the Initial Estimated Liability (IEL) description to clarify that for generation the IEL is based on estimated Qualified Scheduling Entity (QSE)-to-QSE energy sales. A parallel change has been made to the Counter-Party Credit Application. This NPRR also restores the IEL for traders, inadvertently omitted from NPRR741, Clarifications to TPE and EAL Credit Exposure Calculations, and originally defined in NPRR620, Collateral Requirements for Counter-Parties with No Load or Generation. Additionally, this NPRR corrects subscripts in the Minimum Current Exposure (MCE) formula that were inadvertently overwritten by NPRR743, Revision to MCE to Have a Floor For Load Exposure; modifies the RTQQNET and DARTNET in the gray boxed language for NPRR741 to match the current baseline Protocols; and simplifies the MCE formula. This NPRR also removes an obsolete reference to “Deferred Invoice Exposure”, a concept removed by NPRR728, Removal of Language and Definitions Related to NPRR484, Revisions to Congestion Revenue Rights Credit Calculations and Payments, and NPRR554, Clarification of Future Credit Exposure Calculation.
Reason: Market efficiencies or enhancements
