Summary

This Nodal Protocol Revision Request (NPRR) changes language in select provisions in Section 6, Adjustment Period and Real-Time Operations, related to Must-Run Alternatives (MRAs) primarily in grey-boxed language from NPRR885, Must-Run Alternative (MRA) Details and Revisions Resulting from PUCT Project No. 46369, Rulemaking Relating to Reliability Must-Run Service, in order to align the terminology for Energy Storage Resources (ESRs) for the single-model era and specify how Qualified Scheduling Entities (QSEs) representing ESR MRAs would be settled for the provision of MRA Service. The Settlement changes reflect that ESR MRAs would not have fuel costs, but would have costs associated with charging.
