  1. WELCOME TO THE 2006 JPA PLANNING COMMITTEE MEETING

  2. INTRODUCTIONS

  3. JPA AGENDA • Welcome/Introductions • Power Marketing Updates (Oretta) • PD Remarketing • O&M Contracts • Meter Testing Program (Radosevich) • Short Circuit Working Group Update (Field) • OATT NOPR Update (Moulton) • POISE Update (Steward) • 10 Year Studies & Maintenance/Construction Program (Johnston & Radosevich) • Right-of-Way Studies & Standards (Radosevich) • JPA 2006-2007 Goals (Moulton) • Next Meeting • Action Items

  4. POWER MARKETING UPDATES MARY ORETTA (602) 605-2639 oretta@wapa.gov

  5. POWER MARKETING UPDATES • PD Remarketing • O&M Contracts

  6. METER TESTING PROGRAM DAVID RADOSEVICH (602) 605-2605 RADOSEV@wapa.gov

  7. Western’s Integrated Meter Validation Program • Old procedure (standard) is to remove meter from service and bench test to provide an accurate validation of the meter • New procedure being established provides an accurate validation and is preferred because: 1) Does not interrupt power metering or billing 2) Performed faster (costs less to do) 3) Same degree of accuracy 4) Meter is not removed from service 5) Validates meter under actual load conditions

  8. Integrated Meter Validation Procedure • New procedure utilizes an RD-33 reference standard to validate the accuracy of the revenue meter while still in service 1) It measures the actual voltage and current applied to the meter to calculate power 2) It also monitors the KYZ pulse output of the meter 3) It then compares the calculated MW to the pulses received, providing a percent error based on this comparison

  9. Integrated Meter Validation Procedure • Accuracy of the In-service Validation Test is the same as the bench test, since they both use the RD-33 • While the in-service validation is a single test, the bench test consists of several independent tests: 1) All four quadrants (Watts Fwd, Watts Rev, VARS Fwd, VARS Rev) are tested in a bench test 2) In each quadrant, three tests are performed: Full Load (5A) at Unity PF Light Load (0.5A) at Unity PF Full Load (5A) at 0.5 PF

  10. Integrated Meter Validation Procedure • Since the MW load and power factor vary from line to line, the maximum acceptable error for the in-service validation is set to the maximum error allowed in the bench test, 0.3% • If the in-service validation fails to meet this tolerance requirement, a full bench test shall be conducted on the meter • If the loading on the line is insufficient to perform an in-service validation test, a bench test is performed

  11. Integrated Meter Validation Procedure QUESTIONS??

  12. SHORT CIRCUIT WORKING GROUP TOM FIELD (602) 605-2517 field@wapa.gov

  13. JPA SWAT Short Circuit Study Group Update July 12, 2006 Phoenix, AZ

  14. Short Circuit Work affects System Reliability • Relay Misoperations – Fail to Operate or Operate When They Shouldn’t • Equipment Damage due to Failure to Operate Relays • Circuit Breakers and Other Equipment Failure because not Properly Rated

  15. Power System Operational Reliability • Correct Relay Operation • Correct Breaker Ratings • Reliability Depends on Accurate Fault Current Calculations

  16. Reasons to Form Regional Short Circuit Working Group • The interconnected system requires cooperation between everyone for accurate short circuit data • There was no formalized mechanism in place by WECC or other Arizona regional groups for coordination of the short circuit case

  17. SWAT SCWG Footprint

  18. 4 Main Areas of Work • Annual Operating Case • Common Impedance Maps • Common Study Methodologies • Annual Standards Review

  19. Annual Short Circuit Operating Case • Improved Short Circuit Data for Relay Settings • Improved Short Circuit Data for Breaker Duty Evaluations • Improved Short Circuit Data for Safety Grounding and Arc Flash Evaluation • Improved Reliability of System Operation and Safety of Maintenance Personnel

  20. Common Impedance Maps • Useful for seeing Short Circuit Case and Planning Case Updates • One set of maps reduces duplication of effort • Easy to make changes for annual operating case by marking drawings

  21. Common Methodologies • One set of breaker methodologies chosen for the jointly owned stations • Other methods, such as safety grounding, etc. developed as guidelines • Information sharing forum

  22. Annual Standards Review • Breaker Duty Studies, TRV Studies, Switching Studies, and Safety Grounding Studies based on standards • Standards can change without a change in study methodologies • Annual review of standards changes to determine if study methodology changes required

  23. SWAT SCWG Accomplishments • Webpage setup and linked to SWAT Website • Charter (Scope) Finalized • All SWAT Transmission Owners joined • 6 meetings held since starting in January • Monthly meeting schedule • Impedance Map Plan Developed • Working on Combining First Case

  24. SWAT Webpage

  25. SWAT SCWG Webpage

  26. SWAT SCWG Charter

  27. SWAT SCWG Webpage

  28. SWAT SCWG Webpage

  29. Impedance Maps Work • Most Impedance Maps Are Out of Date • List of Items to be Placed On Maps Developed • A Single Set of Impedance Maps to be Generated • Requested SWAT to Develop WestConnect Funding of Impedance Map Generation • Only 2 WestConnect Members not Members of SWAT SCWG

  30. SWAT SCWG Webpage

  31. Combined Case • Plan Developed • Conversions Currently being Checked • Zones for Members being Developed • Equivalents to be Checked • Cases to be Combined

  32. Future Work • Combine CCPG SCWG Case • Combine STEP SCWG Case (if developed) • Develop Common Methodologies • Review of Standards • Start on next Annual Case and Impedance Maps Update (refinements)

  33. Future Refinements • Add Mutual Coupling • Add Line Charging Capacitance • Add Motors • Check Transformer, Line, Shunt, Generator, and Load Data

  34. Questions?

  35. OATT NOPR UPDATE RONALD MOULTON (602) 605-2668 moulton@wapa.gov

  36. NOPR TIMELINE FOR FILING • Notice of Proposed Rulemaking (NOPR) was issued 5-18-06 • OATT NOPR Comments/Compliance Filing Team was formed 6-1-06 • Charter drafted 6-8-06 • Conference Call 6-8-06 to determine issues for response and develop Western’s approach • Regional representatives submit input to the team by COB 6-16-06 • Technical and Legal Team Leads compile input into first draft response by 6-30-06 • Review by Team representatives by COB 7-7-06

  37. NOPR TIMELINE (cont’d) • Technical and Legal Team Leads compile second draft for review by PSOC by COB 7-12-06 • PSOC review completed by 7-17-06 and coordinated with BPA • Team representatives respond to PSOC comments by COB 7-24-06 • Final draft response to DOE’s General Counsel for review by COB 7-26-06 • DOE’s General Counsel review completed by 8-2-06 • Western will submit the completed response to FERC by COB 8-7-06
