Background

Status: Approved
Date Posted: Jun 7, 2022
Sponsor: ERCOT
Urgent: No
Sections: 5.7.1.3 and 9.14.7
Description: This Nodal Protocol Revision Request (NPRR) proposes changes to permit Generation Resources recover their fuel costs when instructed to start due to a Reliability Unit Commitment (RUC) and operate above the Generation Resource’s Low Sustained Limit (LSL). Specifically, this NPRR makes the following changes: • Remove the Max (0) function from the Revenue Less Cost Above LSL During RUC-Committed Hours (RUCEXRR) equation for Resources that have been granted a fuel dispute; • Add a Reliability Unit Commitment Fuel Cost Adder (RUCFCA) to the Real-Time Energy Offer Curve Cost Cap (RTEOCOST) to represent the incremental cost of fuel for generation above LSL; and • Provide clarification to Protocol Section 9.14.7 to allow for the recovery of such fuel costs via RUC Settlements.
Reason: Addresses current operational issues; Market efficiencies or enhancements
