NPRR520  Real-Time Mitigation Rules and Creation of a Real-Time Constraint Competitiveness Test

This primary changes in this Nodal Protocol Revision Request (NPPR) are the following: -The Monthly and Daily Constraint Competitiveness Tests (CCTs) will be replaced with a CCT that is performed as part of the Security-Constrained Economic Dispatch (SCED) process considering only those constraints that are active in SCED and using the current system conditions -The Element Competitiveness Index (ECI) calculation for the Long-Term and SCED CCTs will only be performed on the import side of a constraint -The designation of a constraint as competitive or non-competitive in the SCED CCT will not be dependent on the designation during the Long-Term CCT -The Independent Market Monitor (IMM) is given the ability to designate constraints as either competitive or non-competitive, regardless of CCT results -Only those Entities with decision making authority that have a significant impact in making a constraint non-competitive will be considered for mitigation in SCED -Only those Resources that have a significant contribution in getting the Entity with decision making authority considered for mitigation for a Non-Competitive Constraint will have mitigation applied in SCED -The formula for mitigating energy offers in SCED is changed to include a small adder to the reference price from SCED Step 1 in order to minimize issues caused by the tie breaking logic The use of Mitigated Offer Floors in the SCED process is removed.
