Background

Status: Withdrawn
Date Posted: Feb 25, 2011
Sponsor: ERCOT
Urgent: No
Sections: 3.16, 3.18
Description: This Nodal Protocol Revision Request (NPRR) adds language to incorporate a percentage requirement limiting the amount of Regulation Service that Generation Resources may provide; and to provide for an annual ERCOT review of the percentage requirement limiting the amount of Regulation Service that Generation Resources may provide.
Reason: The reason for this NPRR is to: Increase the distribution of Regulation Responsibilities across the ERCOT System; Improve the dispatchability of On-Line Generation Resource capacity that is available to increase/decrease Security-Constrained Economic Dispatch (SCED) Base Points by minimizing Ramp Rate sharing between SCED and Regulation Service; and Reduce the number of Reliability Unit Commitment (RUC) and Supplemental Ancillary Service Market (SASM) procurements that result from Regulation Service becoming undeliverable in Real-Time due to either a transmission constraint or a Qualified Scheduling Entity’s (QSE’s) failure to provide.
