Agenda
• EDS SLA• EDS 2
– Release 3: Telemetry & State Estimator– Release 4: NOMCR
• EDS 3– Release 5: SCED– Release 6: LFC– Release 7: CRR
• EDS 4– Release 8: COMS– Release 9: DAM / RUC / SASM
3TPTF6/10/2008 3
EDS SLA Metrics (April ‘08)
SCED availability increase 10% from the previous month, ongoing issues with MMS 3
4TPTF6/10/2008 4
EDS SLA Metrics (May ‘08)
SCED availability decreased 5% from the previous month due to combined cycle configuration number issue
5TPTF6/10/2008 5
Significant Environment Outage – Month of May ‘08
• Market Information System (MIS) / Market Manager– Total Outage Time – 10 hours– Primary Issues
• Application process hung, Out of memory fault, Deployment (release) issues• Market Management System (MMS)
– Total Outage Time – 3.5 hours– Primary Issues
• Application server process hung (JBOSS)– Outage time significantly reduced from monitoring– MMS 4 should resolve this issue
• Database table locking from clean-up / purge jobs• LMP’s
– Total “Outage” Time – 20 hours– Note: LMP “Outage” includes time where LMP’s were compromised due to ERCOT system
issues. This does not include LMP issues due to MP’s input data (e.g. ICCP, Energy Offer Curves, etc) unless that data caused an unhandled fault in SCED.
– Primary Issues• LMP’s not updating to MIS / Public Reports• Bad telemetry data from MP causes SCED to fail
– HSL < LSL while EOC does cover the full sustainable capacity of resource causes SCED to fail
– To be resolved in MMS4• Transformer constraint causes SCED to fail
– EMS MMS view required update after EMS release– Resolved after occurrence
6TPTF6/10/2008 6
ICCP Servers Update
• Austin ICCP Servers– Production Servers Upgraded
• Taylor Production Servers – ICCP Associations In Progress– 15 of 23 QSE Associations Completed– 6 of 25 TSP Associations Completed
• ICCP High Availability
7TPTF6/10/2008 7
Wind Telemetry
Wind Telemetry• 54 Wind Units• ICCP Telemetry Available for all Units
• Direction, Speed, Barometric Pressure, Temperature
• Telemetry Accuracy• Incorrect Values
• Telemetry Data Quality• Good, Remote Replaced
• Good, Remote Suspect
Contacting QSE’s
8TPTF6/10/2008 8
Wind Telemetry
• MMS UI Feedback– Concerned about the amount of work needed to view/update
COPs, etc. for multiple resources. Current UI allows user to view multiple days for one unit, not multiple units for one day
– Concerned about the way error and confirmation messages display (not implemented yet)
– Concerned about raw .xml displaying on the Awards tab (not implemented yet)

Over 40 units participated in testing 22 test sessions had to be rescheduled due to failed test attempts or other delays 14 additional test sessions were conducted to handle additional tests (JOUs, re-tests) The test team averaged over 11 test sessions a week for the last 3 weeks of May to meet the test
completion milestone (original plan had 6 scheduled).

reached. Changes in all Resource HDLs/LDLs and Output Schedules as well as GTBD affect the selection of marginal units

ERCOT has executed during April and May:
13 DAMs (constrained and unconstrained, last two without guardrails/scripting)
2 SASMs, 6 DRUCs, 2 HRUCs
QSE participation level excellent overall
ERCOT is suspending DAM execution in existing software environment; will maintain and support the existing EDS environment to allow for QSE market submissions and testing
Suspension will allow focus on expediting migration to MMS4 for EDS, address missing integration to achieve a more realistic DAM/RUC, QSE/ERCOT to focus on EIP testing and delivery
