Status: Approved
Date Posted: Dec 24, 2008
Sponsor: QSE Managers Working Group (QMWG)
Urgent: Yes
Sections: 4.10.6, 5.5.1, 7.3.2
Description: This Protocol Revision Request (PRR) provides specific details for WGR-only QSEs such that the scheduling metric will apply to more Operating Hours.
Reason: This PRR is the result of a task assigned by Wholesale Market Subcommittee (WMS) to the QMWG on April 16, 2008. A discussion about ERCOT’s Balancing Energy calculations in the Scheduling, Pricing, and Dispatching (SPD) software led to the conclusion that the energy schedule of a WGR-only QSE must match the Resource Plan operating level before the ERCOT Operator enters the balancing offset. Section 4.10.6 specifies a measure for this but excludes Resource Plan updates that occur after the end of the Adjustment Period.
