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 ACEclock-min limit (BAAL) with a 30 min time limit
BAs must still continue to calculate and report all NERC required quantities.

6. How-Why
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

7. When - timeline August 2009 – Workshop September 2009 October 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

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
