This Nodal Protocol Revision Request (NPRR) modifies the requirement that Resource Entities submit any changes to their emergency operations or weatherization plans from 30 days to twice per year. The twice-a-year submission requirement would align the Section 3.21 requirements with Section 22, Attachment K, Declaration of Completion of Generation Resource Weatherization Preparations, which is required to be submitted no later than June 1 and December 1 for the applicable summer and winter operating periods. The revisions proposed in this NPRR are consistent with a proposed amendment before the Public Utility Commission of Texas (PUCT) to P.U.C Subst. R. 25.53, Electric Service Emergency Operations Plans (Project 39160, PUC Rulemaking Proceeding Relating to Electric Service Emergency Operations).
