NPRR741  Clarifications to TPE and EAL Credit Exposure Calculations

This Nodal Protocol Revision Request (NPRR): • Simplifies equations for Estimated Aggregate Liability (EAL) and moves Potential Uplift (PUL) to Total Potential Exposure Any (TPEA); • Removes contradictory language for when Initial Estimated Liability (IEL) is to be used; • Applies consistent variable subscripts across applicable Protocol sections; • Corrects defined terms and subscripts; • Eliminates the Congestion Revenue Rights Activity (CRRA) flag to simplify the Total Potential Exposure (TPE) equation. This flag was used to set inclusion of EAL for all the CRR Account Holders represented by the Counter-Party (EALa) in either TPEA or Total Potential Exposure Secured (TPES); • Groups additional parameters to utilize standard change control process; • Clarifies components of Real-Time Liability (RTL) and Outstanding Upaid Transactions (OUT); and • Corrects Minimum Current Exposure (MCE) formula to conform to as-implemented form.
