  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

  3. Agenda • DAM summary for 4/13 and 4/15 • QSE Activities for Next Week • FAQ • General Reminders/Updates • Environment Report • Planned outages • Known Issues • Dashboard Update • Settlements/COMS • Special Topics • Question and Answers / General Discussion • Appendix ERCOT asks that Market Participants log into the WebEx session using their company name and then their name. This will allow ERCOT to take roll-call offline. http://nodal.ercot.com 3

  4. Market Trials 2010 Roadmap http://nodal.ercot.com 4

  5. Submission Overview for Apr 13 Submission overview Overall, 156 QSEs participated for Op Day 4/14 http://nodal.ercot.com 5

  6. Submission Overview for Apr 13 Submission overview http://nodal.ercot.com 6

  7. Submission Overview for Apr 13 Submission overview • Energy Bids from QSEs – 80% of Load was requested. http://nodal.ercot.com 7

  8. Submission Overview for Apr 13 Submission overview • AS Offers • 31 QSEs submitted • No AS insufficiency • AS Self-Arrangement from QSEs • 50% of AS Obligation was requested, ~43-47% received • 38 QSEs sent in AS Self-Arrangement • Energy Only Offers – 82 QSEs submitted EOOs • PTP Obligation Bids – not allowed this week http://nodal.ercot.com 8

  9. Submission Overview for Apr 15 Submission overview Overall, 179 QSEs participated for Op Day 4/16 http://nodal.ercot.com 9

  10. Submission Overview for Apr 15 Submission overview http://nodal.ercot.com 10

  11. Overview for Apr 15 • RRS - Hour 3 cleared at $567 and Hour 19 cleared at $633.49 Analysis: • Hour 3 - Due to a multi-hour block as the marginal offer with high prices • Cost of the block covered by the one hour that the unit is marginal. • Hour 19 - still under review http://nodal.ercot.com 11

  12. Submission Overview for Apr 15 Submission overview • Energy Bids from QSEs – 120% of Load was requested. http://nodal.ercot.com 12

  13. Submission Overview for Apr 15 Submission overview • AS Offers • 30 QSEs submitted • No AS insufficiency • AS Self-Arrangement from QSEs • 50% of AS Obligation was requested, ~37-44% received • 45 QSEs sent in AS Self-Arrangement • Energy Only Offers – 90 QSEs submitted EOOs • PTP Obligation Bids – not allowed this week http://nodal.ercot.com 13

  14. RUC Overview for Apr 15 RUC overview • ERCOT committed three Resources: • TXCITY_CC1_1 for Hours 7-10, 18 • TXCITY_CC1_2 for Hours 11-17 • FRNYPP_CC1_4 for Hours 1-24 • No Resources were decommitted • ERCOT system operations approved this result http://nodal.ercot.com 14

  15. Next Week’s Activities DAM executing on 4/20 and 4/22 (Op Days are 4/21 and 4/23) • Changes from this week’s activities: • Self-Arranged AS no longer requested at 50%; should be submitted at a reasonable quantity that reflects the QSE’s business • PTP Obligation Bids can be submitted again; guardrails are up to 5 bids totaling 50 MW per QSE per hour. • Virtual Bids/Offers guardrails relaxed to 10 transactions per QSE per hour, with no MW restriction; bids/offers should be reasonable • Remember that Tuesday’s Load Bid MW target is 80% of forecasted load, and Thursday’s is 120%. http://nodal.ercot.com 15

  16. Next Week’s Activities DRUC executing on 4/20 and 4/22 after DAM (at 1430) • COP updates required after DAM and DRUC complete (resource status, AS schedule) • COPs will therefore be disconnected from zonal/telemetry - this is expected. Note that outages from zonal will be transferred into nodal starting next week • This transfer will represent approximately 85% of the actual zonal outages http://nodal.ercot.com 16

  17. FAQ Q: Why did my fixed quantity Energy Bid clear above my bid price? A: There is a known effect of the DAM optimization wherein fixed quantity bids could be cleared higher than their bid price (and fixed quantity offers could clear lower than their offer price). This is due to a rule that fixed quantity bids/offers cannot set the price. The issue is described at length in Appendix 7 of the DAM requirements, posted at http://nodal.ercot.com/docs/pd/mms/pd/damsasmr/mms_dam_and_sasm_req_09q1_v4_0%20%28blackline%29.doc. http://nodal.ercot.com 17

  18. General Reminders/Updates • Network Model Update • Next scheduled load is 5/3 • An updated settlement points and MP short name list was posted for the 4/14 model load at http://nodal.ercot.com/readiness/markettrials/index.html • Phase 5 Kick Off WebEx set for April 29, 2010, from 1:00 until 4:00 Central. • Details on the calendar page at http://www.ercot.com/calendar/2010/04/20100429-MT • Phase 5 Handbook for DAM/RUC/SASM was posted on 3/31 • http://nodal.ercot.com/readiness/markettrials/dam/index.html • New AS Plan for next week • We have updated the AS Plan to mirror the zonal AS Plan, effective Op Day 4/18 (previously we were using test data that was flat throughout the day). We will update the nodal AS Plan every month when the zonal plan is updated • NOTE: This means that your AS Obligations will change next week. http://nodal.ercot.com 18

  19. General Reminders/Updates Trade confirmation testing • ERCOT will maintain a list of QSEs that desire to test trade confirmation/bilateral process with other QSEs during market trials • Email sent to Nodal Project Managers with a .xls attachment. • Please fill out the spreadsheet, or send the following information, to MarketTrials@ercot.com with the subject line ‘Trade Confirmation Testing Contacts’ by today (Friday, April 16, 2010). • QSE short name • Contact name for trade confirmation • Phone number • Email address • Once we have received this contact information, we will compile and distribute it to all QSEs participating so that the trading contacts can work together to complete their testing. Note that this information will only be shared with other trading contacts who have volunteered their own information. http://nodal.ercot.com 19

  20. Support Metrics Market Participant Inbound Questions Last Week This Week * This week, 23 out of 267 questions were responded to outside of the 24 hour time frame. http://nodal.ercot.com 20

  21. Day-to-day operations summary: Planned / Unplanned Outages • Outages • Planned Outages • 04/23/10 – 04/25/10 • ERCOT will be performing the initial release for Phase 5 on 4/23 • Due to the size and complexity of the release, it will be necessary to take systems down periodically throughout the weekend • ERCOT will be running a series of tests that Sunday which may result in notifications and / or data in the Nodal Production systems that are associated with that test. • 04/16/10 06:00 P.M. – 04/16/2010 07:00 P.M & 04/17/10 10:00 A.M. – 04/17/2010 11:00 A.M. • Market Manager site failover testing is planned during this period. A brief delay in processing may occur. If authentication errors are encountered, signing back into the application will resolve the issue. • Unplanned Outages • 04/13/10 12:00 P.M. – 04/13/2010 02:30 P.M. • Authentication exceptions were being reported against EWS submissions. Issue occurred as a result of an update to the identity management system. Market Manager was fully functional during this time period. • 04/12/10 09:00 A.M – 6:00 P.M • MPIM Application performance issues were noted during the day. MPs were unable to assign certain roles to user certificates. Any new certificates created during this period with “NMMS” or “EMMS” roles will need to be completely terminated and reissued. http://nodal.ercot.com 21

  22. Environment Report-Known Issues Full DAM/RUC/SASM known issues list will post every Friday night at http://nodal.ercot.com/readiness/markettrials/dam/index.html New DAM/RUC/SASM known issues • There is an issue with the DAM when AS Offers are submitted for two Load Resources that are mapped to the same load point (PTID) in the network model. This is a valid modeling scenario and the DAM software will be updated to deal with this scenario. In the interim, DAM Operators will need to cancel one of the two AS Offers submitted until the defect is fixed., which is planned for the 4/23 release • Two prices were reported for settlement point BVE_CC1. This was due to a modeling error with the 4/14 model load. There are two physical combined cycles “BYU_CC1” and “BVE_CC1” mapped to the same logical resource node. • If causing import issues with your system, workaround is to delete one of the two settlement point prices prior to import • We will communicate the date of fix later http://nodal.ercot.com 22

  23. Environment Report-Known Issues New DAM/RUC/SASM known issues (cont’d) • MMS Phase 2 validation notification messages for Self Arranged AS transactions have an incorrect transaction type identified in the MRID being relayed back. Currently a value of “SAS” is being sent when it should return “SAA” instead. • Get real-time SPP MarketInfo service returns incorrect GMT offset associated with the start time field. The offset currently being returned is set to -06:00 hrs when it should reflect -05:00 hrs. • Request for “AggregatedASOfferCurves” data via EWS MarketInfo service is failing with xsd validation error message. Workaround is to download the report from MIS or via the Get Reports service. • Market Manager – Dropdowns on the Trades page are static and not checking the latest info on the first load of the page. Select a different trade date, then reselect desired trade date and the drop downs will refresh and become dynamic. http://nodal.ercot.com 23

  24. Environment Report-Known Issues New MIS known issues • NP5-751-CD, Daily RUC Committed or Decommitted Resources and NP5-752-CD, Hourly RUC Committed or Decommitted Resources, are currently on the known issues list as delayed reports for Phase 4. These will instead be moving to early Phase 5 delivery. I will be communicating the information contained within these reports either on this weekly call or via email to the Nodal PMs. http://nodal.ercot.com 24

  25. Nodal Scorecard MP16 DAM Participation Metric Results • MPs measured on 50% participation • 5 DAM runs so far (4/1, 4/6, 4/8, 4/13, 4/15) • Submission of DAM specific transactions • All QSEs (includes sub-QSEs) • QSEs with Resources • 54/78 (88% generation) • COPs, TPOs do not count as participation (they count towards Real-Time Metric (MP15A)) • QSEs without Resources • 95/191 • If QSE without Load, transaction choices are Energy Bids, Energy Only Offers, PTP Obligation Bids • 76% load participation • AMBER/RED scores go live on 4/21, MPs contacted this week http://nodal.ercot.com 25

  26. COMS/Settlements Update • Next weeks Operating Dates will be Settled (4/21 and 4/23) • DAM Statements and Invoices and RTM Initial Statements will be posted according to Protocol Timelines • Must have DAM awards or own CRRs to receive a DAM Statement • Extracts will be posted within 48 hours of Statement approvals • COMS/Settlements known issues list will be posted next Wednesday, 4/21 • http://nodal.ercot.com/readiness/markettrials/coms/index.html • May CRR Auction Invoices will be posted on Monday, 4/19 • Phase 5 Settlement Calendar Extract will be posted Friday, 4/23 • Dedicated COMS call beginning the first week in May http://nodal.ercot.com 26

  28. Special Topics DAM run on 4/13: • A resource with an exclusive TPO was not fully dispatched for energy, even though the LMP at that resource node was greater than the resource’s incremental offer price for two operating hours (discovered by the price validation tool). This occurred because the SPP for this resource node during one post-process of the DAM engine was different than that during another due to a shift factor inconsistency. • This inconsistency will happen when: • a contingency outages generators or Energy only offers/bids, and; • this contingency results in binding/violated constraints. • In Network Security Monitor (NSM)/Network Constrained Unit Commitment (NCUC), contingencies that outage generators or loads require special process. The main point is to preserve power balance in post contingency scenario. • LMP calculations require shift factors at electrical buses/settlement points, which is based on network topology only. • But due to special processing in NSM/NCUC, the optimization results in situations where LMP and MW on offer/bid curve are not consistent. http://nodal.ercot.com 28

  29. Special Topics JOUs and COP consistencies • In DAM, if the different owners of the jointly-owned unit have submitted conflicting COP statuses for the current day, online statuses will overwrite offline statuses when DAM is determining the initial condition of the unit (i.e., is the unit online or offline at the start of the next operating day. • In RUC, if the different owners have conflicting COP statuses for the next operating day: • If any owner has OUT status for any hour then the unit is considered OUT. • If all owners have submitted a COP, and at least one of them has an online status in a particular hour then the resource status for the unit is online (unless any owner has OUT) http://nodal.ercot.com 29

See MIS Handbook for a comprehensive list of reports available - http://nodal.ercot.com/readiness/markettrials/mis/index.html. * Denotes MIS Certified reports http://nodal.ercot.com 45

  46. Special Topics Phase 2 Validation reports and process • Phase 2 validation re-evaluates all submitted transactions at 7 am in the day-ahead with updated information, such as AS Obligation, CRR ownership, credit limits, etc. • If there is a validation error, ERCOT will cancel the transaction • We send a notification that a Phase 2 report is available for a particular transactions type, and notification containing the cancellation for the transaction. • You can query for the Phase 2 report via web service or on the Reports page of the Market Manager in order to view the reason for the cancellation. • Correct and resubmit prior to 10 am. • Note that submissions are locked out during the Phase 2 process, which is currently taking about 15 minutes to complete. http://nodal.ercot.com 46

  47. Special Topics Day-Ahead Self Commitment DAM clearing engine treats your TPO differently if you submit Startup and Minimum Energy (SU/ME) costs as $0 vs. NULL • If you submit with SU/ME as $0, DAM engine treats this as a normal offer where the QSE is not requesting SU/ME to be covered. HSL/LSL constraints will be respected. Also, if you are selected for an online Ancillary Service, you will also be awarded at least LSL on your offer curve. • If you submit with SU/ME as NULL, DAM engine is signaled to ignore the HSL/LSL constraints for the resource. In this scenario, the offer curve submitted will start at 0 MW and go to the max MW quantity desired – again, DAM will ignore LSL/HSL constraints. If the offer curve submitted doesn’t start at 0 MW, it will be extended to 0 MW by DAM. If the resource is selected for Ancillary Services, no requirement to also award TPO at LSL (since no LSL constraint honored in this case). http://nodal.ercot.com 47

  48. Special Topics Day-Ahead Self Commitment The purpose of the NULL: It allows a QSE to use part of a Resource to serve its own load, and then offer in the rest to the DAM and enable the offer to be co-optimized with its AS Offer. Example: A Resource has 100 MW LSL and 400 MW HSL, and the QSE has already committed 300 MW of the Resource through some other mechanism. The QSE wishes to offer the remaining 100 MW, which would otherwise be ignored due to the 100 MW LSL. Then going into real-time, so QSEs will need to update their TPO to cover the full capacity of the resource, from LSL to HSL, rather than from 0 MW. To do that if the resource is awarded in the DAM, the QSE must provide a reason code, which is DSCM. This functionality came about due to TPTF subgroup on the issue. It has not yet been added to the protocols but will during our protocol traceability/cleanup effort. http://nodal.ercot.com 48

  49. Special Topics Bid/Offer efficiencies • ERCOT has identified efficiencies in Bid/Offers submission with regard to the format of submission • This applies to all transaction that use a Bid ID or an Offer ID (Energy Only Offers, Energy Only Bids, PTP Obligation Bids, and CRR Offers) • Preference is for QSEs to submit the same Bid/Offer ID for each hour in the submission, versus submitting a different Bid/Offer ID for every hour. The market system treats the submission the exact same way, regardless of which format is used • Using the preferred format will optimize DAM system performance • For xml examples detailing this issue, please view a document that will be posted along with this presentation on the calendar page at http://www.ercot.com/calendar/2010/04/20100409-MT • This was discussed at NATF 4/6, we send an email to the nodal technical contacts that we have on file for all QSEs, and we will add it to the External Interfaces Specification http://nodal.ercot.com 49
