Background

Status: Approved
Date Posted: May 22, 2006
Sponsor: Reliant Energy
Urgent: Yes
Sections: 4.7.2 (2), 6.9.2.1.1
Description: The PRR revises Section 6.9.2.1.1, Replacement Reserve Under Scheduled Capacity, to charge QSE™s for ERCOT-wide RPRS based on their net ERCOT-wide position. A clarification is also included for Section 4.7.2(2) which refers to sections of the Protocols that use the Schedule Mismatch amount
Reason: When ERCOT procures Replacement Reserve Service (RPRS) for System-wide Insufficiency, the current Protocols charge QSEs based on their net position in each zone, instead of the QSE™s overall ERCOT-wide position (which is the appropriate comparison in the event of procurement for system-wide insufficiency). This PRR modifies the calculation of the charge to assess an underscheduled charge for system-wide RPRS to QSEs when they are net-short on a system-wide basis
