2 2 2 TPTF6/10/2008 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

3 3 3 TPTF6/10/2008 EDS SLA Metrics (April ‘08)  SCED availability increase 10% from the previous month, ongoing issues with MMS 3

4 4 4 TPTF6/10/2008 EDS SLA Metrics (May ‘08)  SCED availability decreased 5% from the previous month due to combined cycle configuration number issue

5 5 5 TPTF6/10/2008 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

6 6 6 TPTF6/10/2008 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

7 7 7 TPTF6/10/2008 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

8 8 8 TPTF6/10/2008 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)

22 22 TPTF6/10/2008 Telemetry Availability vs Mismatch and Convergence 6/5 6am-Noon

23 23 TPTF6/10/2008 Nodal SE Convergence: 6/5  6/5 7am: Bad Transformer SCADA at Nueces_B Station  6/5 8am: Lost 4453 Analog measurements & 8144 status measurements & Incorrect breaker status at station HOC  6/5 9am: Lost 4453 Analog measurements & 8144 status measurements  6/5 10am: loss in data caused N_Sharpe Phase Shifter tap to incorrectly estimate causing mismatches. 6/5 6am-Noon

24 24 TPTF6/10/2008 Limits during test period 6/5, 7am – 11am  GTBD within 500-1000MW of HDL (most units deployed as high as possible)

25 25 TPTF6/10/2008 Reference LMPs Vs GTBD (6/5)  Compensating for Resources “invisible” to SCED by 7:20 brought LMPs off cap  Flat spots from 8:15-8:50 and 10:30-10:45 due to 300-500MW of flat EOC on marginal units  Jumps from 9:30-10:00 due to switching between two groups of marginal units as dispatch limits are reached. Changes in all Resource HDLs/LDLs and Output Schedules as well as GTBD affect the selection of marginal units

26 26 TPTF6/10/2008 Reference LMPs Vs MCPE (6/5)  Reference LMP comparable to MCPE  LMPs in west zone were lower than reference LMP  Nodal LMP indicative of submitted TPOs – very good
