Summary
This NPRR removes Operating Reserve Demand Curve (ORDC) Phase 2; changes the High Ancillary Service Limit (HASL) calculation to remove Non-Frequency Responsive Capacity (NFRC) included in a Generation Resource’s High Sustained Limit (HSL), thereby creating the opportunity for an ORDC payment for the NFRC capacity through Ancillary Service imbalance Settlement; and clarifies the HASL definition between use in the Resource limit calculator, Reliability Unit Commitment (RUC) optimization, and the capacity shortfall ratio share.
