  2. Antitrust Admonition ANTITRUST ADMONITION ERCOT strictly prohibits Market Participants and their employees who are participating in ERCOT activities from using their participation in ERCOT activities as a forum for engaging in practices or communications that violate the antitrust laws. The ERCOT Board has approved guidelines for members of ERCOT Committees, Subcommittees and Working Groups to be reviewed and followed by each Market Participant attending ERCOT meetings. If you have not received a copy of these Guidelines, copies are available at the Client Relations desk. Please remember your ongoing obligation to comply with all applicable laws, including the antitrust laws. DISCLAIMER All presentations and materials submitted by Market Participants or any other Entity to ERCOT staff for this meeting are received and posted with the acknowledgement that the information will be considered public in accordance with the ERCOT Websites Content Management Operating Procedure. http://nodal.ercot.com 2

  8. Market TrialsCongestion Revenue Rights Weekly Update September 24, 2010 http://nodal.ercot.com 8

  9. Known Issues • Topology Processor (software that creates the PSS/E file from the Network data) does not export the outages to CRR’s PSS/E file • CRR team has a workaround by using the TCR PSS/E file with outages and augmenting it for the CRR application • Update: Fixed. This was not only a code change, but a procedure change as well. The outages file shows line outages – however, the Topology Processor wants the breakers and switches instead of the lines. We currently believe that we will be using the ‘normal’ model build procedure for the December model from the Topology Processor. • Most recent build from vendor updated a parameter that caused the Counterparty credit limit editor page to be disabled. Vendor has fixed the issue, and the patch is scheduled for release in early October.

  25. Week in Review • 168 Hour Operating Days (9-9 through 9-15) • All DAM Statements and Invoices have posted • 9-14 RTM Initial Statements will post today, 9-15 will post on Monday, 9-27 • 9-17 was a No-DAM date. Testing DAM failure Operational Scenario • 9-2 and 9-3 Operating Days were not supposed to be supported Operating Days, but RTM Initial Statements were posted. DAMs were run internally, so there is DAM Market Input Data (such as DAES, DAEP). QSEs will have issues shadowing Real Time Energy Imbalance for those dates since they don’t have the DAMCODE extracts that show the Day Ahead Records. • Manual process for recovering missing TWTG was implemented on 9-15 for Interval Ending 96 http://nodal.ercot.com 25

  26. Next Week’s Activities Next week is the last week that Statements, Invoices and Extracts will be posted http://nodal.ercot.com 26

  27. RUC Short Fall Totals during 168 Hour Test http://nodal.ercot.com 27

  28. Environment Report-Known Issues COMS New Known Issues • TWTG is not being time-weighted according to SCED interval duration, it is being calculated as the simple average of generation over the settlement interval COMS Closed Issues • AIEC EOCPRCAP is not calculated correctly when RTPERFIP is missing • Day Ahead Start Up Eligibility is not working correctly with a DAM commitment that does not start in HE 1 is contiguous to a RUC Commitment that started in HE 1. • A DAM commit in an interval other than interval 1 for the current Operating Day should not look at any other commit in the current Op Day, to determine a DAM Start • QCLAW - RUC and SELF - SELF commits generate a QCLAW when they should not when self commits s are connected to each other • QCLAW - A SELF - RUC -DAM commit with the SELF being in later RUC process than the RUC should yield the SELF commits as QCLAW intervals • If a resource comes online at exactly 1 minute before the end of an hour (XX:59:00) the flag that determines Energy Eligibility in the DAM Make-Whole payment will not be generated correctly Reminder: ERCOT will post known issues every Friday to the readiness center at: http://nodal.ercot.com/readiness/markettrials/coms/index.html http://nodal.ercot.com 28

  29. Environment Report-Known Issues Settlements Remaining Defects: • The current implementation of TELHSLFLAG is not appropriately exempting resources from Base Point Deviation during startup.  The methodology proposed in NPRR 273 (exemption when the resource is in an ONTEST status) provides a feasible and efficient option for correcting this issue by go-live. • TWTG is not being time-weighted according to SCED interval duration, it is being calculated as the simple average of generation over the 15-minute settlement interval.  This issue will be addressed at QMWG (next week) along with other issues being incorporated into an NPRR for the Base Point Deviation charge. • Effective with the 09/28/2010 posting of the Public Reference Data Extract (PRDE) the QUEUE_STATUS column will be removed from the following tables: • RUCPROCESSHISTORY • CRRSETTLEPOINT Reminder: ERCOT will post known issues every Friday to the readiness center at: http://nodal.ercot.com/readiness/markettrials/coms/index.html http://nodal.ercot.com 29

  30. Settlements - FAQs Q: How do I calculate Real Time Ancillary Services Obligations (RUO, RRO, RDO, NSO)? A: The protocols in section 6.7.3 don’t show the actual market wide total bill determinants that are used in the calculation. The correct bill determinants are shown in the Nodal Settlements Matrix. “TOT” records should replace the records show below in red. The formulas will be corrected in a Settlements “clean-up” NPRR. Protocol Formula: RUO q = (SARUQ q + (RTPCRU q, m)+ PCRU q – RURP q – RUFQq) * HLRSq+ RURP q Matrix Formula: RUO q= (SARUQTOT + (RTPCRUTOT) + PCRUTOT– RURPTOT – RUFQTOT) * HLRS q + RURP q http://nodal.ercot.com 30
