Sections:
Description: This System Change Request (SCR) proposes to modify the ERCOT Network Model Management System (NMMS) and Topology Processor to incorporate Geomagnetically-Induced Currents (GIC) modeling data for maintaining GIC System models for the Electric Reliability Council of Texas, Inc. (ERCOT) planning area for compliance with North American Electric Reliability Corporation (NERC) Reliability Standard, TPL-007-4, Transmission System Planned Performance for Geomagnetic Disturbance Events. The NMMS and Topology Processor should allow applicable Entities to provide the necessary data for the GIC System Model, per Section 6.11 of the ERCOT Planning Guide and in accordance with ERCOT’s GIC System Model Procedure Manual. Additional changes are requested to include automated email notifications of the need for the GIC modeling data submittals and updates.
Reason: Market efficiencies or enhancements, Regulatory requirements
