• No Resources were decommitted

• ERCOT system operations approved this result


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%.

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

.


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.

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 [email protected] 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.


Support Metrics

* This week, 23 out of 267 questions were responded to outside of the 24 hour time frame.

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.


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



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.



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.

• First RTM Invoice will be posted on 5/6– It will invoice the RTM Initial Statement for operating day 4-21

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:

1) a contingency outages generators or Energy only offers/bids, and;

2) 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.


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)

* Denotes MIS Certified reports

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.


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).


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.


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
