Sections:	6.10.4.4, Schedule Control Error; 6.10.5.4, Responsive Reserve Services Performance Monitoring Criteria; 6.5.4, Responsive Reserve Service; 6.10.3, Ancillary Services Qualification Criteria and Portfolio Test Methods
Description:	Correct the Schedule Control Error (SCE) to reflect Loads acting as Resource (LaaR) obligation when it is deployed. Revise the Responsive Reserve Service (RRS) Performance Monitoring Criteria to accurately reflect compliant performance by Qualified Scheduling Entities (QSEs). Moved language regarding LaaRs and bids from Combined Cycle plants from Section 6.10.5.4 to Section 6.5.4 since this is a more appropriate place for this language. Revised Section 6.10.3 to update Ancillary Service (AS) Re-Qualification language to reflect new criteria.
Reason:	The SCE equation should be corrected so a QSEâ??s SCE does not go positive during a low frequency event with LaaR deployment and cause the QSE to move their portfolio down. The current RRS criteria was intended to cover QSEs providing only RRS and did not consider other Ancillary Service deployments. The proposed criteria better indicates QSEs who are compliant and is more reasonable to use when determining if QSEs should be granted AS Re-qualification based on past performance.
