  13. Delay of True Up Settlements • Variances between extracts and SCR 727 data have caused delays in retailers ability to validate settlement data. • ERCOT Staff is working to correct variances, but True Ups continue. • Thus any corrections would be uplifted instead of being properly settled against the market. • Proposal would continue to provide settlement updates, but would allow for True Up after data corrections have been made.

  14. Proposed language The Board finds that due to unusual circumstances arising from errors in Data Archive extracts needed by market participants to reconcile retail customer assignments and usage data, ERCOT should delay 2003 True-Up Settlement Statements to allow market participants to verify their settlement statements using complete data extracts obtained from ERCOT. Pursuant to the authority of the Board of Directors Section 9.2.7 of the ERCOT Protocols, all true-ups for 2003 shall be delayed until market participants have a reasonable amount of time to load complete data extracts and analyze the data, and sufficient time to process any alleged variances as follows: (1) 2003 True-Up Settlement Statements will begin no earlier than 120 days from the date that ERCOT provides the first complete SCR 727 data extracts related to 2003 to market participants, as determined by ERCOT, and (2) alleged data variances indicated in the extracts affecting 2003 True-Up Settlement Statements must be submitted to ERCOT in chronological order beginning 90 days from the date that ERCOT provides the first extract related to 2003. Pursuant to the authority of the Board of Directors Section 9.2.5 of the ERCOT Protocols, beginning October 1, 2003, ERCOT shall issue Resettlement Statements beginning with 2003 Trade Days June 10, 11, 12, 13, 16, 17, 19, 20, 21, 22, 24, and 25 and continue thereafter with Resettlement Statements for January 1, 2003, and following Trade Days, until such time as the True Up Settlement Statements for 2003 begin, as provided in this resolution.
