5. QSE Qualification Call Overview: Overview and Scope of Call
All topics will be focused on QSEs and will serve as the primary means for ERCOT to communicate information to the QSEs
The qualification focus of the call will last through the month of January, 2010
Feb, 2010 the call focus will shift to Real Time Market and LFC
The QSE Qualification Call will cover agenda items related to
Frequently Asked Questions and issues experienced
Any program updates to scope, schedule or activities
Nodal production environment status and known issues
Overall status of QSE Qualification
Other non-qualification related agenda items
ERCOT Readiness Team MP Outreach Effort
Nodal Telemetry Outreach Effort 5

6. Environment Report: Planned / Unplanned Outages
Planned Outages (note these are outages planned to occur during supported environment hours)
Currently there are no planned outages to report
Unplanned Outages
12/30/2009: ERCOT released the Nodal Production environment early on December 29, During this early release period it was discovered that resource data was corrupted, placing some resources under the wrong QSE. ERCOT confirmed that 1 QSE accessed the Resource Parameters interface and was able to retrieve another QSE’s Resource Parameters
The environment was immediately shut down until resolved
ERCOT Legal will notify impacted QSEs and file a notice of protocol violation with the Commission
Root cause: A tool used to load data into the development environments was erroneously pointed at the Nodal Production environment
Corrective Action:
Development data loader is now separate from Production data loader
Improved verification process
Back up of environment DB prior to data load process 6

7. Environment Report: Known Issues
ERCOT will post known issues every Friday to the readiness center at:
New issues and resolved issues will be presented and discussed weekly on this call
<Review Known Issues Spreadsheet> 7

8. Environment Report: Changes to Supported Environment Hours
Environment Availability for January 2010
The Nodal Production Environment will be available Monday – Thursday from 8am – 6pm
Outside of these hours, ERCOT will be executing performance testing and patch migrations based on testing results
For those MPs that provided ERCOT test certificates, there will be test notifications sent to your listeners during these internal ERCOT tests
ERCOT transactions will be limited to using Sundays as trade dates
MPs should avoid Sunday for submitting qualification transactions
Please note that only functionality that pertains to the CRR and QSE qualification activities has been validated and are supported
Other features (such as reports and other MIS functionality) may be present in the environment but may have issues
ERCOT is still in the process of validating features to be released for Market Trials Phase 3 8

10. Standing reports and updates: General Reminders / Updates
URLs for access the Nodal Production systems
MIS:
Market Manager: Click the ‘Applications’ tab in the upper menu. Link is in the ERCOT Applications portlet
CRR: Click the ‘Markets’ Link in the upper menu. Click CRR in the Market sub menu
EWS:
Market Trials Phase 3 Kick Off / MRS 2
ERCOT will host these on Jan. 28th, starting at 9am
Location is the Austin Met center as well as via WebEx
Details are posted at
Reminder: Market Trials address change: ERCOT asks that MPs use the address for questions from this point forward
This will begin the phasing out of and addresses.
A centralized address will no longer require MPs to “guess” which address to use for their questions
We have implemented a more effective method of routing and responding to s using this address
The old eds s can continue to be used until 2009 hold over efforts are completed (such as telemetry outreach)

11. Nodal Telemetry Outreach Update
Recap of NTO Objectives and Timelines:
Market Participant
Data Type / Measure
For SE
(Due 12/31/09)
For SCED
(Due 02/01/10)
QSEs with Resources
Gen Unit Gross Power Flow (MW/MV) ■
Gen Unit Net Power Flow (MW/MV)
Breaker/AVR Status (ST)
Generation Plant Auxiliary Load (MW)
All other ICCP as required per ICCP Communication HB
TSPs
All ICCP as required per the ICCP Communication HB
ERCOT’s goal is to have all Nodal telemetry completed by Feb 1, 2010
The Focused Input Test (FIT) series for State Estimator ended in Dec 2009 (the final FIT window was conducted Dec 1 – 3, 2009)
Telemetry support for State Estimator is being provided on a daily basis during business hours as of January 4, 2010.

12. Nodal Telemetry Outreach Update
Telemetry Dashboards
As part of dashboard and status reports for Market Trials, ERCOT will maintain QSE and TSP Telemetry Dashboards on the Readiness Center at (
Telemetry Dashboards will be published following each nodal database load
The next Telemetry Dashboard publication is scheduled for JAN 29 and will reflect telemetry status as of the JAN 20 nodal database load and will include measurements for all nodal telemetry as required to support both State Estimator and SCED
Current QSE Telemetry Status
Of the 46 QSEs who are receiving point lists:
28 QSEs have provided 100% of their nodal telemetry for State Estimator
4 QSEs have provided less than 80% of their nodal telemetry for State Estimator
14 QSEs have point lists under review with ERCOT
Over 90% of the nodal points required to support State Estimator have been provided to date

13. Nodal Telemetry Outreach Update
Next Steps
In JAN 2010, the focus of the Nodal Telemetry Outreach shifts from State Estimator to SCED. Approximately 1000 nodal ICCP points for Generation will need to be added to the network model to support SCED execution in Market Trials Phase 3.
The status indicators for SCED telemetry will be updated in the QSE Telemetry Dashboard on the Readiness Center Following the JAN 20 nodal database load.
Beginning next week (the week of JAN 12), ERCOT will begin working with QSEs to address nodal data quality issues in addition to missing nodal points
Also beginning next week (the week of JAN 12), ERCOT will begin working with QSEs that have Load Resources and Controllable Load Resources to complete missing nodal Ancillary Service points—approximately 1700 such points will need to be added.

14. Qualification Update ERCOT Opened the Nodal Production environment:
MMS on 12/30/2009
CRR on 1/4/2010
Mandatory qualification activities will continue through Jan 28
ERCOT has identified 39 QSEs that did not participate in qualification activities in 2007 and 2008 and will require a formal qualification conference call
All of these QSEs have been contacted; 22 have responded and scheduled a qualification call
The schedule of calls may be confirmed at Note that this is updated every Friday
Currently 1 QSE that participated in the 2007 / 2008 qualifications has requested an optional qualification call (requests can be sent to )
39 QSEs have completed qualification out of 287
A dash board is posted every Friday of QSEs that have completed qualification (note those QSEs that qualified last week will be posted this Friday)
