to recommend approval of NPRR1140 as recommended by PRS in the 9/15/22 PRS Report and the 9/27/22 Revised Impact Analysis; with a proposed effective date of 11/4/22 for Section 9.14.7 and upon system implementation for all remaining language
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.
