Major challenge for Nodal is the successful integration of CIM data between NMMS, EMS, MMS and other Nodal systems

CIM critical dependency is on successful model integration of EMS, MMS and NMMS

Market Trials Mitigation

NMMS

Initial Design complete. Refactoring in progress.

ERCOT NMMS testing exporter since April

2007

Data Model: updated per downstream system

request. Will need to sync up data model versions in

the future

Data: ON GOING, waiting for EMS importer

NOMCR Market Trials • Model exchange with multiple vendors on-going

• Planning Interoperability Test with all vendors at ERCOT

MMS

Initial Design complete. Refactoring in progress

MMS CIM importer testing since November

2007. Outstanding issues communicated to

NMMS team

Data Model: Few critical issues remain. MMS

Application able to import NMMS Nodal Model. Will

need to sync up data model versions in the

future

Data: ON GOING,

Starting to use CIM for 9.3 Trials

• ABB maintaining detailed prioritized spreadsheet with all modeling and data issues.

• ERCOT helping define and execute CIM importer tests during MMS3 pre-FAT&FAT and MMS4 pre-FAT&FAT

• ERCOT performing internal due diligence of all CIM attributes necessary to execute all functions

• Regular conversations on the status of the CIM importer between ERCOT & ABB (technical leads, project engineers and project managers)

EMS

Initial Design in progress. Network Model testing in progress.

Data model: Network model validation in

progress. Will need to sync up data model

versions in the future

Data: ON GOING

Not Using CIM • ERCOT escalation to AREVA mgmt on delay of product

• ERCOT personnel planned to be at AREVA to push delivery

• ERCOT doing preliminary testing in parallel to reduce testing cycle

• ERCOT setting up hardware in advance of product delivery
