Resolution from 01-22-2003

(1) Further true-up resettlements for 2002 will be suspended and (2) True-up resettlement (starting with January 1, 2002) will resume when adequate accuracy can be assured (as developed by the RMS and approved by the TAC) and 45 days after SCR 727 has been implemented.  Every effort will be made to resume true-ups by April 1, 2003.  Progress toward completion criteria will be reviewed at each RMS Meeting and reported to the TAC and the Board monthly.  If the April 1, 2003 date cannot be met, the Board shall be advised and a revised target resumption date shall be given.  


RMS recommended Resettlement Criteria

1 Develop functionality and provide data extract as defined in SCR 727.

2 Market Sync completion criteria will be 95% complete for ERCOT and CR groups and 95% complete for each TDSP for Priorities 1,2,4(1) and 5 as reported on the Market Sync Reporting tool status.

3 Outstanding QRE issues documented by ERCOT as of 12/16/02 be 95% complete. (“In Progress” and “In Analysis” as reported to RMS 12-18-2002)

4 ERCOT shall have the organization and procedures in place to daily synchronize ERCOT’s Siebel and Lodestar systems, and synchronization of Siebel and Lodestar systems shall be in place before the initial release of SCR727 data to Market Participants.

rms action plan
RMS Action Plan
  • Continue to close QRE requests, reduce the number of market sync miss-matched records, and syncing of Siebel & Lodestar.
  • Develop a tactical plan to operational-ize SCR 727 extract so MPs use this data to identify and repair ESI ID components and identify out of sync records after August 11, 2002.
  • The RMS will bring all the restart resettlement criteria including additional details on SCR 727 extract for a TAC vote at the March 2003 TAC Meeting.
tac direction
TAC Direction
  • ERCOT: make SCR 727 data extracts available as soon as possible
  • RMS: Consider effected ESI IDs (customers), and the results from the February 7th Siebel and Lodestar synchronization activities, and bring an amended resolution to the TAC for consideration at its March Meeting.
  • The motion was approved by a 25 to 0 vote with 1 abstention.
