  5. Release 4 – NMMS / NOMCR Sep Oct Nov Dec Jan 2008 2007 Feb Network Model Verification NOMCR Checkout E2 R4 R4: NOMCR / Network Model verification • Start of EDS 2 - R4 NOMCR has been moved to start the week of 3/17/2008 • NMMS became available in a “Sandbox” environment enabling market participants to become familiar with the system 1/28/2008 • NMMS/NOMCR overview training has been completed by the market participants • Citrix connections and digital certificates have been successfully installed and validated for 100% of the market participants • MOD on Demand module became available in a “Sandbox” for planners • Access have been granted and validated with the market participants to use PTC and MOD application functionalities • Testing scenarios and acceptance testing are currently in the development phase • Market participants have been scheduled to attend CIM class on 2/26/08 • Quick reference materials and users guide on how to use the system, create and maintain projects, and change requests were distributed to the market participants • A narrated web-based version of the NMMS course and training material are now available on lineat: http://nodal.ercot.com/training/courses/nc09.html#materials TPTF

  7. Release 5 - SCED Sep Oct Nov Dec Jan 2008 2007 Feb 6-month LMP Posting RT ICCP E3 R5 SCED R5.1 SCED R5.2 SCED R5.3: RT ICCP SCED R5.4: LMP Post Legend: % in parentheses are from the 1/21 TPTF update TPTF

  8. SPPs –West 345Kv Hub Invalid CC Configuration 02/9 02/10 2/11 02/12 02/13 Given sufficient inputs the output of SCED are reasonable and can be sustained over a period of time. TPTF

  9. LMP Reasonableness • Market Operations presented a document to TPTF at the Nov 5&6th meeting on reasonableness. • The document described preconditions of data accuracy and system functionality and a few basic scenarios to validate the system including: • No constraints are activated - All nodes will have the same final LMP • No constraints are activated and GTBD (Generation to be dispatched) is increased - All nodes will have the same final LMP but will be higher than the LMP in the case with lower GTBD • A single constraint is activated – The LMP at the nodes with negative Shift Factor will be higher than LMP at the nodes with positive Shift Factor • All constraints are competitive - no price mitigation is done on the offer curves TPTF

  10. This covers scenario 1 through 4 TPTF
