  1. NERC TADS Update Andrew Slone, Engineer, Reliability Performance Analysis WECC RPEWG Meeting May 14, 2013

  2. Agenda • TADS Transition • Quarterly Reporting • Key Inventory Fields • Bulk Electric System Alignment • TADS Training/Webinars • WECC Specific TADS Information • WECC TO Direct Upload • Importing TRD Data Into TADS • WECC-FAC-501 Study Update

  3. TADS Transition Timeline

  4. TADS Quarterly Reporting • TADS Changing from Annual to Quarterly Reporting Schedule • Transmission Owners Should Submit TADS Outage Data 45 Days After Each Quarter • Data Changes for Prior Quarters: • During entry period, can update prior quarter outages • Freeze Period • After entry period ends, prior quarter outages are “frozen” and cannot be edited • Current quarter outages, however, can be added/updated • Deep-Freeze • At end of Quarter 4 reporting, all outage and inventory data can no longer be edited

  5. TADS Key Inventory Fields • TADS Changing from Summary Inventory to Individual Inventory • Inventory Forms Closely Resemble TRD, but Some Differences • Entity Unique Element ID Added • In lieu of TO Operator name and Element ID (e.g. TOElement1) • Can be Alphanumeric, including underscore • {Regional Entity, NCR, Element ID} combination will be unique NERC-wide • Instead of “In-service Date”, “Change/Reconfiguration Date” • Should be modified when circuit miles change to calculate proper equivalent circuit miles • Instead of “Parent Code”, “Precursor Element” • Can input multiple Precursor Elements

  6. TADS Key Inventory Fields • Common Corridor (WECC Only) • Common Corridor information can be bulk uploaded into webTADS • Follows TRD definitions • AC Multi-Circuit Structure Miles calculated from Common Corridor • TADS Considers Element In-service Date as 1/1/2013 if Element In-service Date is ≤ 12/31/2012 • BES Exception Field to handle new BES definition

  7. TADS Bulk Electric System Alignment • TADS to Align with New Bulk Electric System Definition in 2014 • Includes the Following BES Elements: • AC Circuits • DC Circuits • Transmission Transformers (No GSUs) • AC/DC Back to Back Converters • Two New Voltage Classes • BES 100-199 kV • BES Less than 100 kV* • *The Bulk Electric System definition has a bright-line at 100 kV, but there is an option to include Less than 100 kV Elements by special inclusion

  8. TADS Bulk Electric System Alignment • Elements > 200 kV, but excluded from BES? • 2013: Continue to report in TADS • 2014: Mark Element in inventory as “BES Excepted” and retire Element as of 1/1/2014. Element is no longer TADS-reportable. • BES Exceptions Approved After 1/1/2014: • Mark Element in inventory as “BES Excepted” and retire Element as of BES Exception approval date. • Element is no longer TADS-reportable after BES Exception approval date.

  9. TADS Training • 3 Combined Software/Data TADS Training Classes Prior to June 30 Deadline • Will cover enough material for successful June 30 data submission • Additional Training Dates TBA for July, August, and September • Will cover enough material for successful September 30 data submission

  10. WECC Specific TADS Information • WECC Transmission Owner Direct Upload • WECC TOs will now upload to TADS directly instead of WECC DRE • WECC 2012 TRD inventory data already uploaded into webTADS • By June 30, WECC TOs should verify that all of their Element IDs are in webTADS and that circuit mileage for Elements is accurate as of January 1, 2013 • By September 30, WECC TOs should upload their outage data into webTADS • Possible to Have WECC-Specific Training, if Desired

  11. WECC-FAC-501 Enhancements • Trend average outage rates for the 7 sectors with more outages on lines with the standard over time • Evaluate whether average outage rates have changed since 2008 • Use outage rates per mile to see if the results are the same • Study cause code impact on the 7 sectors: • Controllable cause codes • Failed AC Substation Equipment, Human Error, Failed AC Circuit Equipment, Failed Protection System Equipment • Contamination, Foreign Interference, Power System Condition • Vandalism (Terrorism, or Malicious Acts) • Environmental, Vegetation, Fire, Other • Uncontrollable cause codes • Lightning, Weather excluding lightning, Unknown • Consider outage duration, start time and climate (e.g., terrain) • Consider violation records (FAC-501-1 and PRC-STD-005-1) • IPC and BPA Pre-2008 Outage Analysis • Analyzing Pre-2008 and Post-2008 Outage Data to Determine Effectiveness of WECC-FAC-501 Standard
