NPRR527 Required Combined Cycle Telemetry for Operational Awareness and PDCWG Analysis
ReasonThis NPRR allows the Performance, Disturbance, Compliance Working Group (PDCWG) to accurately measure the Primary Frequency Response of individual components of Combined Cycle Generation Resources while using ERCOT collected data necessary to analyze each Measurable Event. Revisions to the ERCOT Nodal ICCP Communications Handbook will be required as a result of this NPRR. The Qualified Scheduling Entity (QSE) Managers Working Group (QMWG) and the PDCWG unanimously agreed that this telemetry needs to be submitted to ERCOT at their 11/28/12 joint meeting. However, in subsequent discussion and vetting of the NPRR in PDCWG meetings, member consensus has developed on the need to have a total Non-Frequency Responsive Capacity (NFRC) value for each Combined Cycle Generation Resource in operation instead of a value of NFRC for each combustion turbine and steam turbine generator component.

Summary
This Nodal Protocol Revision Request (NPRR) requires Combined Cycle Generation Resources to telemeter individual High Sustainable Limits (HSLs) for gas and steam turbines. The HSLs for combustion and steam turbines were previously submitted in the zonal market and ERCOT requests this practice be resumed in the Nodal market.
