  1. IT Update on Impact of Additional Congestion Zones

  2. IT Update – Additional Congestion Zones • EMMS • Proportional increase in processing window for Real Time Balancing Energy market • Going from 4 to 5 zones will cause up to a 30% increase • Current: 70-160 seconds (per 15 minute interval) • New: 100-200 seconds • When zonal congestion exists the market execution time increases exponentially • Increased market execution times will be managed by moving the market start time to allow for an end time that meets protocol

  3. IT Update – Additional Congestion Zones • Lodestar • Batch performance likely to increase proportionately to the percentage increase in the number of CM Zones • Going from 4 to 5 zones would cause a 25% increase • Current: 2 hours per trade date • New: 2.5-2.75 hours per trade date • Job processing time increases could limit the number of trade days that can be settled per night • Current: 4-5 settlement runs per night • Processing times will increase gradually over the course of the year since new zones initially impact only “Initial” runs • In 2003, system improvements have been able to offset the increase in processing due to additional zones • Replicated source system implementation should provide more flexibility to run more trade days each night

  4. IT Update – Additional Congestion Zones • Data Archive/Data Warehouse • Increase in data volume will result in incremental storage needs and lengthened batch processing windows • Data extract volumes will increase for certain extracts • Portal • Nominal TCR impact (greater data volumes)

  5. IT Update – Additional Congestion Zones • We can provide more detailed impact metrics in February (after the 5th CM Zone is added) • Questions?
