Description: This Nodal Protocol Revision Request (NPRR) addresses a number of changes pertaining to the Emergency Response Service (ERS): 1) Allows previously committed ERS Resources to participate in Must-Run Alternative (MRA) Agreements as ordered in Public Utility Commission of Texas (PUCT) Project No. 45927, Rulemaking Regarding Emergency Response Service. 2) Modifies the methodology for evaluating the performance during the first partial interval for ERS Loads on the alternate baseline. The current methodology produces incorrect results when the average Load for the first partial interval is above its maximum base Load, but in reality the Load responded according to the instruction. 3) Provides edits pertaining to the self-serve capacity associated with an ERS Generator. This change is necessary to define the acceptable parameters for self-serve capacity. 4) Adds Protocol language that will set the ERSTESTPF to significantly lower values and in some instances to zero for ERS Resources with three consecutive test failures in a 365 day period. In those instances where the ERSTESTPF are set to zero there will be no ERS payment for these Resources for the Standard Contract Term for which the third test failure occurred. 5) Provides additional administrative changes and clarifications to existing Protocol language pertaining to ERS.
Reason: Addresses current operational issues; Administrative; Regulatory Requirements
