Status: Approved

Sponsor: ERCOT
Urgent: No
Sections:, 6.7.4, 9.5.3
Description: This Nodal Protocol Revision Request (NPRR) defines the System-Wide Discount Factor and clarifies the role of this factor in the formulas used in the Settlements of the Operating Reserve Demand Curve (ORDC). This NPRR also corrects an error in the formula for calculating the Real-Time Ancillary Service Imbalance Amount in Section 6.7.4. ERCOT notes that these Settlement formulas were not available prior to the design and implementation of ORDC Settlements and therefore were not included in NPRR 568, which created the ORDC. The revised formulas, which have been vetted by the Communications and Settlements Working Group (CSWG) and discussed with participants in ORDC training, will provide additional clarity needed for Market Participants to effectively shadow ORDC Settlement calculations.
Reason: Provides clarity to Settlements language and the formulas that were implemented for ORDC.
