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
WECC TRDTF

• 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
WECC TRDTF
• TRDTF Meetings:– PDX 2005
• 11.16 & 11.17• 12.14 & 12.15
– SRP 2006• 2.15 & 2.16• 3.23 & 3.24• 4.16 & 4.17
– Conference Call – Respond to website comments• 8.24
WECC TRDTF
• Purpose– Develop a transmission outage database
for Performance Category Upgrade Requests
– RPEWG – Monitor, Evaluate and Report Performance to WECC – core charge
– Continued…
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
WECC TRDTF
• Completed Documents– User’s 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
User’s Manual
– User’s Manual for Reporting WECC Common Transmission Outage Database
– Two Parts• Outage Information Table• Transmission Circuit and Transformer Attribute
Table
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
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.
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)
Costs of Implementation
• Survey of TRDTF– SRP, APS, Western (4 offices), BCTC, and
WECC
• 1st Year Costs– $6k – $55k, $30k Avg.
• Subsequent Years– $1k - $24k, $10k Avg.
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
Implementation Responsibilities
• WECC Staff– Receives annual data– Compiles and Manages Continuously– Answers Database ‘how to’ questions– Produces the Annual Report– Provides information to RPEWG
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
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
WECC TRDTF
• Exhibit C – Collection and Review of Transmission Forced Outage Data– Passed in RPIC 8 to 2 - 9.21.06– 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
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
For PCC/OC Approval
• For Approval vote – • Approval of the (2) Documents:
– User’s 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
