NOTICE TYPE:  M-A081514-01 Operations

SHORT DESCRIPTION:  Preparations for implementation of NPRR527 – ERCOT will be ready to receive required Combined Cycle Telemetry for Operational Awareness and PDCWG Analysis on September 10, 2014 

INTENDED AUDIENCE:  QSEs and Resource Entities

DAY AFFECTED:  September 10, 2014

LONG DESCRIPTION:  On September 10, 2014, ERCOT will complete its portion of the implementation of Nodal Protocol Revision Request (NPRR) 527, Required Combined Cycle Telemetry for Operational Awareness and PDCWG Analysis.

NPRR527 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.  Qualified Scheduling Entities (QSEs) representing Combined Cycle Generation Resources will be required to provide new Real-Time telemetry for Non-Frequency Responsive Capacity (NFRC) to ERCOT for each Combined Cycle Generation Resource.  ERCOT will be ready to receive this new telemetry point from QSEs on September 10, 2014. 

ERCOT Staff will solicit input on the implementation of NPRR527 at the August 21^st PDCWG meeting and the August 26^th QSE Managers Working Group (QMWG) before setting a deadline for QSEs to provide the telemetry required by NPRR527.  A follow up Market Notice will be sent with the timeline for full implementation and unboxing of Protocol language for NPRR527 at a later date.   The ERCOT Nodal ICCP Communication Handbook will also be revised to incorporate the additional telemetry requirement for NFRC.

ADDITIONAL INFORMATION: NPRR527 and associated documents can be found on the ERCOT website.

Information on upcoming releases can be found on the Project Priority List (PPL).
