8.IDCWG Maintenance

  1. IDC operation:

i.IDC Alarms  Raja Thappetaobula will discuss an issue related to IDC TLR not showing up, which may lead to a MISO requested IDC change order to develop a backup IDC TLR alarm.

  1. Event/incident reports – OATI
  1. Review Help Desk calls

9.New Projects, Issues, Other

  1. WebSDX Documentation
  2. The working group will review Version 1.0 of the Balancing Authority webSDX User Guide for Providing Generator Outputs andPriority and Version 2.3 of the webSDX User Administrator Registration Guide to determine if these documents require revision to support implementation of IDC CO-322.
  3. The Documentation Self-Directed Work Team developed and will request approval of Version 9 of the webSDX User’s Manual. The draft user’s manual is posted under Related Files at
  4. The Documentation Self-Directed Work Team developedand will request approval of its scope*.
  5. Timeline for IDC Model Uploads and Updates* LaChelle Brooks updated the timeline for IDC model uploads and updates for working group review and approval.
  6. Data in NERC Monthly Summary of TLR Logs versus data in the TLR Logs*Neil Shah will provide an overview of potential discrepancies between data shown in the NERC Monthly Summary of TLR Logs versus data is the TLR Logs. The monthly summaries are available at Mr. Shah provided two examples of the potential data discrepancies.

Example:

Row 219 in the Monthly Summary Report for August 2010 shows summary of a TLR Event (max level - 5B) on FG # 6002 – MHEX_S which lasted 0.2 hours. The summary also shows 192,942MWs of curtailment. The TLR Log file (please see attached) for the same event shows 1508 MWs. Similarly for a TLR Event (Row 250) on the same flowgate which lasted 0.97 hours, the summary shows 44,149.2 MWs of curtailment while the TLR log files (also attached) shows 345 MWs of curtailment.

  1. IDC Data Requests  Vice Chair Watson and Raja Thappetaobula will report on their efforts to develop a proposal that will allow IDC users increased functionality to query the IDC.
  2. Book of Flowgates Archived Base Case  Currently the Book of Flowgates allows user to download the current and prior month IDC base cases. The working group will consider expanding the existing download functionality to allow users to download the past 35 monthly IDC base cases.
  3. External Wind Farm Modeling  At its last meeting, the working group extensively discussed the IDC modeling of a wind farm located in a balancing authority within the SPP reliability coordinator reliability area that is serving firm load in the TVA balancing authority using firm transmission service. The working group discussed entity responsibilities for submission of wind farm generator outages and related information to the webSDX. SPP and TVA will provide a status report of their ongoing discussions.
  4. Reliability Coordinator Acknowledgement of TLR CurtailmentsAt its last meeting the working group discussed reliability coordinator acknowledgement of TLR curtailments. OATI was tasked to query the IDC to determine how often the reliability coordinators do not acknowledge TLR curtailments. OATI will report its findings.
  5. NERC Data Exchange WebsiteOATI hosts the NERC data exchange website at The site hosts TDF and GSF matrices and TLR event data. The site is available to the public using a single user id (NERC) and password ($z905kz$). Larry Kezele will provide an overview of the website and its history of development.
  6. Change Order Prioritization  The working group will continue its discussion of prioritizing change order development for 2012.
  7. GSF and GLDF Calculations  OATI will inform the working group of recent efforts to identify the cause of sporadic inaccuracies in the IDC’s calculation of GSF and GLDF matrices.
  8. Reference Document Review
  9. Parallel Flow Calculation Procedure Reference Document – At its August 2011 meeting, Larry Kezele recommended that the working group not expend additional resources to revise the Parallel Flow Calculation Procedure Reference Document, given that theNAESB BPS will be rewriting the TLR business practices to implement the approvedpermanent solution.
  10. Reliability Coordinator Reference Document – At its August 2011 meeting, Chair Bahbaz requested the Documentation SDWT to review the status of the Reliability Coordinator Reference Document.
