  1. PRR Impact Analysis Update Steve Wallace Program Management Office October Board Meeting

  2. PRR Requests and Impact Analysis Plan • Why this topic now? • ERCOT going through its annual budget and fee setting exercise • F&A Committee and Board have requested that ERCOT staff provide additional details as it relates to PRR’s and SCR’s so that the long term costs of the PRR/SCR are part of the Board approval process • Current rate of PRR requests/adoption more than double 2002 rate and increasing • This rate of PRR’s has significant impact ERCOT staff to create impact analysis and implement and maintain the approved PRR’s (short and long term, $’s/FTE’s not in plan) • We are still in an additive phase for the PRR’s & SCR’s vs. replacing functions/protocols

  3. Sample Unplanned PRR/SCR Impacts *= Long term staffing support in business and IT requested as part of 2004 budget/fee request

  4. PRR Requests and Impact Analysis Plan • Current process for impact analysis set to improve with PRR 441 (Protocol Revision Impact Analysis and Implementation Information Enhancement) • Recommendation: • Using PRR441 as a base (Enhanced Impact Analysis), each PRR brought to TAC with completed impact analysis and initial 3 year estimated project and staff costs. Deliver updated information to Board as available as part of TAC packet. • Work to deliver high level impact analysis and estimates prior to PRS meeting (target is 80-90% of PRR’s prior to PRS, Urgent Timeline Issue, late postings, etc.) • Direct ERCOT staff to fully support PRR 441 with the additional financial details, effective with January PRS, TAC, F&A and Board meetings • Deliver with the following confidence levels, impact analysis to: • PRS – 60%, initial high level estimate • TAC – 70%, high level estimate, including PRS changes to PRR/SCR • BOD – 80%, planning estimate, including TAC changes to PRR/SCR • Follow the enhanced template and program process flow shown on next slide • Enhanced process will give PRS, TAC, F&A and the Board the financial and staffing impacts of proposed PRR’s and SCR’s.
