Background

Status: Approved
Date Posted: Aug 18, 2009
Sponsor: ERCOT
Urgent: No
Sections: 6.6.9, 6.6.9.1, 6.6.9.2, 8.1.1.2
Description: This Nodal Protocol Revision Request (NPRR) replaces the seasonal testing requirement with unannounced Generation Resource testing and adds a requirement for Qualified Scheduling Entities (QSEs) to seasonally update their Resources’ High Sustainable Limits (HSLs). The NPRR also leverages existing emergency operations Settlement functionality to provide a mechanism to compensate a Generation Resource for the additional energy above the pre-test Security-Constrained Economic Dispatch (SCED) Base Point during the unannounced Generation Resource test period. This NPRR synchronizes the Nodal Protocols with the process added to the zonal Protocols pursuant to Protocol Revision Request (PRR) 750, Unannounced Generation Capacity Testing.
Reason: To provide a mechanism for ERCOT to verify that reported HSLs truly reflect a Resource’s capability.
