1 WECC Reliability Based Control Field Trial

2 Overview Basic plan for the FT FT document – what’s new/different Roles & responsibilities Readiness - EMS changes? Data reporting Evaluation Questions

3 Who, what, when, where, how, why All of us – BAs, RC, PWG, SDT Monitor, act, collect, report, analyze, summarize March 1, 2010 – February 28, 2011 Real-time & Historical EMS Changes? Monitoring Tools? Support the SDT and for “our” benefit

4 FT Document – Major Changes Version 4 vs Version 8 Potentially obfuscating changes have been addressed\  ATEC is now a standard  ADI references have been removed References to AGC status, suspension of control, response to BAAL violations have been revised Revised Timeline – start date & milestones Evaluation criteria expanded to monitor all paths Loosened verification of BA operator readiness Additional data collection/reporting to address WECC concerns

5 Who-What All BAs with Peak Load or Max Gen > 500 MW must participate All BAs must be able to meet the data collection reporting requirements in Appendix A.  ACE, Frequency related clock-minute values  Count minutes in different violation categories All BAs will control to meet BAL-001 and BAL-007 While CPS2 is waived, it must still be calculated BAL-007 – a frequency based ACE clock-min limit (BAAL) with a 30 min time limit BAs must still continue to calculate and report all NERC required quantities.

6 No EMS modifications are required and BAs may “loosen” control within limits “Loosen” control will differ depending on software BAs can modify their EMS – if they wish BAs can self-implement the BAAL calculation and monitoring of ACE or use tools provided by the SDT The SDT tools are for monitoring only and reference the ACE history (e.g. a PI database) BAs verify to PWG that Operators are trained in RBC Support the SDT in assessment of RBC Consider in WECC control metrics that reflect VGS How-Why

7 August 2009 – Workshop September 2009  PWG posts updated FT document  BAs begin preparing for FT October 2009  OC approves the FT plan and document  OC posts the FT plan for Board approval December 2009  Board approves FT plan When - timeline

8 When – timeline continued January 2010  PWG conducts final workshop or conference call (TBD)  RC certify readiness February 2010  BAs annual update of frequency bias terms  BAs certify readiness  BAs forward 2 weeks of FT data to PWG/WECC  RC certifies all BAs are providing requisite data  PWG forwards list of participating BAs to SDT for CPS2 compliance waiver  PWG announces commencement of FT March 2010  FT begins 03/01/ :00:00 CST  3/15/2010 – BAs submit two weeks of data

9 When – timeline continued April 2010 – March 2011  BAs submit data  BAs note and describe circumstances where ACE exceed BAAL for more than 10 or 20 consecutive clock-minutes  PWG / SDT conference call and review of BA data Open conference call – BAs may participate Consider enhancements/improvements to the FT
