Background

Status: Approved
Date Posted: Jun 15, 2007
Sponsor: ERCOT Staff
Urgent: No
Sections: 4.4.9.2, Startup Offer & Minimum-Energy Offer; 4.4.9.2.3, Startup Offer & Minimum-Energy Offer Generic Caps; 4.6.2.3 Day-Ahead Make-Whole Settlements; 5.6.2, RUC Startup Cost Eligibility; 5.7.1.1, RUC Guarantee; and 5.7.3, Payment When ERCOT Decommits a QSE-Committed Resource
Description: This NPRR Clarifies the sections that dealing with whether a Resource is Eligible for startup compensation in the Day-Ahead and Reliability Unit Commitment (RUC) Make-Whole payment calculations; modifies the definition of the hours used in calculating the RUC Decommitment Payment in Section 5.7.3; and Corrects the parentheses in three formulas in Section 5.7.1.1.
Reason: The current Protocol language in Section 5.7.3 does not address the possibility of a Resource being committed within the Operating Day some time after a RUC Decommitment within that Operating Day. Also, the current language in Section 5.7.3 does not clearly define the hours to use in the RUC Decommitment Payment calculation when the RUC Decommitment spans multiple Operating Days. In addition, the Startup Eligibility in Day-Ahead and RUC Make-Whole payment calculations needs clarification.Three formulas need parentheses corrections.
