Completed on Feb 15th. The calculation of the LMPs are reasonable given the input data, but the input data needs improvement.

Legend: % in parentheses are from the 2/22 TPTF update

14TPTF4/1/2008 14

Recent Issues with LMPs

• Poor quality of ICCP data will cause SE & TCM to not publish results to MMS; therefore stale LMPs & BPs or uniform LMPs

• EMS – MMS interface shuts down daily (reported Oracle issue); therefore stale LMPs & BPs

• COP / TPO / OS submissions to SCED are sufficient

EMS MMS

Market Participant

Starting in Mid-April, ERCOT will contact MPs Real-Time desks when data issues cause SE / TCM failures. This will be done 24x7

LFC 6.3 pre-Test

• Prior to R6.3 (total system test) the market desires an open loop test to validate SCED dispatch. Approach to accomplish this:– QSEs w/ Resources submit Excel files with EOC, OS, INC/DEC

on 4/8 that deconstruct Zonal activities for Operating period 4/7 7-9am

– Perform open loop test on 4/25 from 7-9am– Perform open loop test on 5/5 from 10-noon– Perform open loop test on 4/12 from 4-6pm

• ERCOT to provide QSEs with settlement impact resulting from OOME and Local Balancing had units followed SCEB BP

• Please refer to details provided during the 3/14 workshop: http://www.ercot.com/calendar/2008/03/20080314-EDS3-6.html
