Summary

This Nodal Operating Guide Revision Request (NOGRR) modifies the monitoring equipment installation deadlines established by NOGRR255, High Resolution Data Requirements, to January 1, 2029 in a manner consistent with North American Electric Reliability Corporation (NERC) Reliability Standard, PRC-028-01, Disturbance Monitoring and Reporting Requirements for Inverter-Based Resources. This language also clarifies that synchronized resources that have Standard Generation Interconnection Agreements (SGIAs) executed prior to July 25, 2024 (the date in which the Public Utility Commission of Texas (PUCT) approved NOGRR255) have 12 months beyond their Commercial Operations Date to comply with the new equipment standards.
