Background

Status: Approved
Date Posted: Jun 6, 2010
Sponsor: ERCOT
Urgent: No
Sections: 5.7.4.1.1
Description: This Nodal Protocol Revision Request (NPRR) proposes revisions to paragraphs (9) and (10) of Section 5.7.4.1.1 to conform these paragraphs with paragraph (1), and to clarify how to perform Settlements pursuant to paragraph (1).
Reason: NPRR050, Clarifications for HSL Values for WGRs and WGR Values to be Used in the RUC Capacity Short Calculation, made changes to the treatment of capacity for Wind-powered Generation Resources (WGRs) when calculating the Reliability Unit Commitment (RUC) Capacity Shortfall for a Qualified Scheduling Entity (QSE). This conceptual change was described in paragraph (1) of Section 5.7.4.1.1. However, the corresponding changes were not made to paragraphs (9) and (10), which implement the capacity shortfall calculation. This NPRR provides transparency to the as-built system implementation that supports paragraph (1).
