  1. MARS Taskforce RMS Update October 15, 2008

  2. MARS Taskforce October 8, 2008 Meeting • Reviewed Project Schedule for Planning Phase provided by ERCOT • Business Requirements - 12/02/2008 • ERCOT Enhanced LSE Design- 12/09/2008 • Conceptual Design - 01/07/2009 • Detail Designs - 02/09/2009 • Test Plan - 02/16/2009 • Planning Complete 02/20/2009

  3. October 8, 2008 Meeting • Reviewed: • 4 of Currently 13 Use Cases • Use Case #1 – NAESB Acknowledgement • Use Case #5 – Later Timestamp overwrites Earlier Timestamp • Use Case #6 - Data available to CRs through web services • Use Case #13- No change to be made to retail transaction processing - Retail market NIDR 867_03F stop date vs. IDR 867_03F stop date used to complete a service order.

  4. What is Use Case #13? • Retail market NIDR 867_03 (Final) stop date vs. IDR 867_03 (Final) stop date used to complete a service order and the impacts of the difference when using Advanced Meter data in settlement . • How the REP of Record (ROR) history is maintained for ESI IDs with Advanced meters? • How/what usage is used in settlement and what is affiliated with the 810?

  5. Use Case #13 – Taskforce Recommendation • For the Interim Settlement Solution MARS recommends that ERCOT be allowed to continue their current processes for Non-IDR 867_03 Final transactions, this would mean: • NIDR 867_03 Finals (F) will continue to be used to complete service orders and maintain the REP history. Therefore, ERCOT will continue to stop the REP history with the day prior to the date received in the 867_03 Finals at 23:59:59. • For the Long-Term Settlement Solution on this issue, MARS recommends that this issue should be thoroughly vetted by the Advanced Metering Implementation Team (AMIT) and Market Stakeholders for the appropriate market resolution because of the numerous settlement implications.

  6. October 8, 2008 Meeting • We started brainstorming what business and technical requirements would be needed by Market Participants for the design of the TDSP’s FTP Site. • Follow-up meetings will include feedback from several questions and action items that were identified during this discussion for the CRs and TDSPs

  7. Next Steps for MARS • Our next scheduled meeting dates: • Day/Date : Thursday, October 23, 2008 • Day/Date : Thursday, October 30, 2008 • Day/Date : Monday, November 10, 2008 • Location: ERCOT Met Center Conf. RM 206A • Agenda for these meetings: • Continue to review and finalize use cases • Continue to better define requirements and resolve issues and/or gaps • Continue to complete and resolve action items by providing timely feedback
