NOTICE DATE:  February 24, 2017


SHORT DESCRIPTION:  Implementation Details of NPRR272


DAY AFFECTED:  March 9, 2017

LONG DESCRIPTION:  On March 9, 2017, Nodal Protocol Revision Request (NPRR) 272, Definition and Participation of Quick Start Generation Resources, will be implemented.

This Nodal Protocol Revision Request (NPRR) allows for effective participation of Quick Start Generation Resources (QSGRs) in Security-Constrained Economic Dispatch (SCED).

The QSE for a QSGR that is available for deployment by SCED shall set the Current Operating Plan (COP) Resource Status to OFFQS, and the COP Low Sustained Limit (LSL) and COP HSL values to the expected sustainable LSL and HSL for the QSGR for the hour.  If the QSGR is providing Non-Spinning Reserve (Non-Spin) service, then the Ancillary Service Resource Responsibility for Non-Spin shall be set to the Resource’s QSE-assigned Non-Spin responsibility in the COP.

In order for SCED to recognize that the QSGR can be dispatched, the QSGR shall telemeter a Resource Status of OFFQS and a LSL of zero prior to receiving a deployment instruction from SCED. The QSGR that is providing Off-Line Non-Spin shall always telemeter an Ancillary Service Resource Responsibility for Non-Spin to reflect the Resource’s Non-Spin obligation and shall always telemeter an Ancillary Service Schedule for Non-Spin of zero to make the capacity available for SCED.

ADDITIONAL INFORMATION:  Pursuant to Nodal Protocol Section 21.6, Nodal Protocol Revision Implementation, ERCOT is required to provide notice as soon as practicable, but no later than ten days prior to implementation.   

NPRR272 and associated documents can be found on the ERCOT website.
