NPRR221 Day-Ahead Market and Real-Time Market Default Allocation Changes
ReasonThis NPRR alleviates concerns about DAM participation in the event of a large default in the DAM. Instead of short paying DAM sales for default amounts in the DAM and only allocating to QSEs on a Load Ratio Share basis for default amounts in the RTM, this NPRR allocates default amounts to all QSEs and CRR Account Holders based on their maximum level of MWh activity in ERCOT-run markets. This NPRR also reduces exposure to defaults in the DAM by accelerating the DAM Invoice payment due date by one day.

Summary
This Nodal Protocol Revision Request (NPRR) changes the way default amounts (amounts owed to ERCOT by defaulting Counter-Party 180 days after the default occurs) in the Day-Ahead Market (DAM) and Real-Time Market (RTM) are allocated. This NPRR assigns a share of the default to each Counter-Party based on the greatest of the Counter-Party’s MWh activity in either the CRR market or DAM or RTM at the Counter-Party level for the calendar month prior to the month in which the default occurs. The Counter-Party share of the default is invoiced to the Counter-Party’s Qualified Scheduling Entities (QSEs) or Congestion Revenue Right (CRR) Account Holders, pro rata based on each of the Counter-Party QSE’s or Counter-Party CRR Account Holder’s share of the Counter-Party’s maximum MWh activity. The level of MWh activity in the CRR market and DAM is measured as the greater of the MWh purchases or sales in that market and the level of MWh activity in the RTM is measured as the greater of the Counter-Party’s MWh Load or generation, excluding generation from Reliability Must-Run (RMR) Resources and other Resources during Reliability Unit Commitment (RUC)-Committed Intervals. Language that currently exists in Sections 9.4.3 and 9.7.3 was consolidated and used to create new Section 9.19. This NPRR also accelerates the DAM Invoice payment due date by one day. This NPRR also includes revisions to synchronize the Nodal Protocols with the zonal Protocols as revised by Protocol Revision Request (PRR) 817, Cease Late Payment Charges for Defaulted Entities, to clarify how much security may be held back to be used to pay subsequent minor Invoices as they come due.
