1 TRDTF Transmission Reliability Database Task Force Update & Approval Vote Brian Keel SRP 10.06

2 WECC TRDTF PCC & OC presentations in 2005 & 2006 Late 2005 –Asked to re-tool the database with Operator input Convened the Transmission Reliability Database Task Force = TRDTF

3 WECC TRDTF Members: Brian Keel SRP – Chair Sheldon Yan BCTC Phil Park BCTC Jeff Billinton AESO Chuck Miller WACM Baj Agrawal APS Tom Glock APS Roy Ellis BPA Wen Li BCTC Jose Silva SRP

4 WECC TRDTF TRDTF Meetings: –PDX & & –SRP & & & 4.17 –Conference Call – Respond to website comments 8.24

5 WECC TRDTF Purpose –Develop a transmission outage database for Performance Category Upgrade Requests –RPEWG – Monitor, Evaluate and Report Performance to WECC – core charge –Continued…

6 WECC TRDTF –WECC aggregate transmission line performance monitor and tracking –Facilitate Probabilistic Planning –Provide for a common format for general use if desired, i.e., all of Western adopted

7 WECC TRDTF Completed Documents –Users Manual for Reporting WECC Common Transmission Outage Database –Forced Outage Performance of 200kV and above Transmission Lines, Cable and Transformers –Costs of Implementation Developed –Input Spreadsheet Formed Recently released to WECC website for review

8 Users Manual –Users Manual for Reporting WECC Common Transmission Outage Database –Two Parts Outage Information Table Transmission Circuit and Transformer Attribute Table

9 Outage Information Table Transmission Lines, Transmission Cables and Transformers –Operator –Equipment Code –Start – Stop Time –Outage Cause Code –Outage Mode – Independent, Dependent or Common Mode

10 Attribute Tables –Transmission Circuits/Cables From, To, Miles, Type, kV, Conductors per phase, Overhead ground wire, insulation, cable type, Structure materials and types, common corridor, terrain and elevation. –Transformer 3 Phase or Single Phase, Location, high & low side kV, Rating, In Service/Retirement Dates.

11 Forced Outage Performance… Annual Report on Aggregated Data Momentary and Sustained Outage Performance Circuit, Cables and Transformer –Per circuit, per 100 miles, duration –kV, cause code, cause code & common mode (if applicable)

12 Costs of Implementation Survey of TRDTF –SRP, APS, Western (4 offices), BCTC, and WECC 1 st Year Costs –$6k – $55k, $30k Avg. Subsequent Years –$1k - $24k, $10k Avg.

13 Input Spreadsheet WECC Website Posting current Field testing until February 1, 2007 with 2006 data Edited per field testing Re-released March 1, 2007 Complete data due May 1, 2007 Subsequent years, annual data due February 15 PCC Reps are Responsible for Reporting

14 Implementation Responsibilities WECC Staff –Receives annual data –Compiles and Manages Continuously –Answers Database how to questions –Produces the Annual Report –Provides information to RPEWG

15 Implementation Responsibilities RPEWG –Members only have access to Raw Data –Access to data governed by RPIC Approved Exhibit C –Raw outage information to compare performance to WECC Performance Criteria, Table W-1

16 Implementation Responsibilities RS - Reliability Subcommittee –A designated contact, RS member, responds to usage questions, or changes to database structure, format, definitions, interpretations and Final Report. –Reviews and Approves for release Final Report –RS Designee can call formation of Task Force

17 WECC TRDTF Exhibit C – Collection and Review of Transmission Forced Outage Data –Passed in RPIC 8 to –Defines Access to Transmission Reliability Database Only members of RPEWG and WECC Staff members will have access to raw data RPEWG members will be posted on WECC website

18 WECC TRDTF Conclusions: –Operator and Planning Input –3 Support Documents written –Inputs, Outputs, and Procedure Defined –Survey of Member and WECC costs –Confidentiality covered in Exhibit C

19 For PCC/OC Approval For Approval vote – Approval of the (2) Documents: –Users Manual for Reporting to WECC Common transmission Outage Database; –Forced Outage Performance of 200kV and above Transmission Lines, Cables and Transformers; Charges WECC Staff/RPEWG to collect and aggregate the transmission outage data and Reliability Subcommittee to issue Annual Report starting in May 2007 for 2006 outage data
