  1. Protocol Revision Subcommittee Presentation to the ERCOT Technical Advisory Committee August 4, 2005

  2. PRS Summary • 2006 System Prioritization Tasks • 7 PRRs for Approval

  3. 2006 PRS Prioritization • TAC tasked PRS to: • Validate that prioritization definitions used by ERCOT and market reviews were the same • Review ERCOT project list & CBAs • PRS reviewed definitions used by ERCOT – same definitions • PRS reviewed more than 24 ERCOT projects & CBAs • Improved understanding of ERCOT projects and provided input on ERCOT CBAs

  4. 2006 PRS Prioritization • PRS Findings • ERCOT identified 2 1.1 projects currently below the line that should be moved above the line (reliability related) • PRS identified 1 2.1 project that ERCOT should review for possible move (PRR 409 related to Voltage Support) • Given current projected funding, several projects will likely be “bumped” down below the line • PRS continues to identify 1.1s from new PRRs • Mass Customer Transition is a 1.2 until project is scoped

  5. 2006 PRS Prioritization • PRS Findings • Data Extract projects are 1.2s and not likely to be completed but provide value to the market through increased transparency • Extracts can increase efficiency, in part, by reducing disputes that occupy stakeholder/ERCOT time • Extracts need to be integrated into ERCOT work plans instead of special project designation • Policy Question – how can good ideas be implemented to take advantage of stakeholder knowledge and contributions?
