  1. SO – CART Project Status Protocol Revision Subcommittee Update 2/23/06

  2. EMMS Release R4A RAP-C Modeling Enhancements Replace DSM6 High-Speed Frequency Recorder RTCA Archiving Performance Monitoring for SCADA / State Estimator EMMS Software Upgrade - OSI PI, OAG Satellite Communications for Black Start suppliers EDW EMMS Extracts Congestion Management Reports Aggregation of Combined Cycle Units Providing RRS SCE Performance and Monitoring Additional SMP Front End Incident Report OTS System CSC Thermal & Volt Limits Calculations/Posting Outage Scheduler Enhancements Phase II DC Tie Automation Topology Estimation System Phase I Network Model Management System (NMMS) SCR 747 – Removal of Price Administration for Zonal Congestion Market Notice of LaaR Proration Breaker to Breaker One Lines/System Map Improvements to VSA/DSA - Phase II MOMS EMS Upgrade SCR 746 – Dynamic Rating Data to TSP Using ICCP Link AIMMS 3.6 SO Projects Completed or near completion New or Not Started Active (at least in Initiation)

  3. RAP-C Modeling Enhancements Gives the ability to enter conditional RAPs Checks the topology for the defined condition and provides an indication that the RAP will work if the contingency occurs RTCA Archiving Real-time Contingency Analysis data necessary for IROL, SOL & Congestion Management Reports Performance Monitoring for SCADA/State Estimator Automatically evaluate the redundancy & observability of the network Monitors SCADA & SE performance Replace DSM6 High-Speed Frequency Recorder Monitors & Collects frequency disturbance data for PDCWG reports Satellite Communication for Black Start Suppliers Provides the ability to communicate via satellite phone during a system blackout or emergency situation EMMS Software Upgrade – OSI PI, OAG Upgrade to a more supportable version of ICCP EMMS Release R4A PRR342 PRR359 PRR413 PRR422 PRR485 Enhanced the OOM tool Provided more real-time update of the resource plan Replacement is nearing completion AS Simultaneous Selection Completed or Near Completion

  4. Congestion Management Reports PRR 492, PRR 515 RTCA Archiving provides the data and this project represents the reporting and user interface Reports will be used for identifying overloads and re-occurring congestion Aggregation of Combine Cycle PRR 502, OGR 149 Counts responsive reserve on the entire train instead of individual units SCE Performance and Monitoring PRR 525 Implemented sending EMS values to QSEs Enhancements to the EDW reporting function near completion Additional SMP Front End Provides QSE RTU connection Provides capacity for new QSE requests (Currently near capacity) Incident Report Automates the ability of the operator to generate a compliance violation email and route to the appropriate management OTS System (Operator Training Simulator) Training that can be applied toward operator certification hour requirements Ability to train on scenarios for historical and or new events CSC Thermal & Volt Limits Calculation/Posting Automates the process of calculating CSC limits Incorporates a 24 hour load study rather than a manual peak hour study Active (at least in Initiation)

  5. Outage Scheduler Enhancements Phase II PRR 425 Validate TO input data Introduce tracking of outage schedule changes DC Tie Automation Automate Comparison of eTags to QSE DC Tie Schedules Automate Operator offsets for DC Tie eTag/Schedule mismatches Monitor/compare eTag Net Scheduled Interchange to DC Tie SCADA on EMS Display Automate Inadvertent Energy Accounting Topology Estimation System Phase I Identify incorrect switching device status Proof of concept Pave the way for system integration and nodal requirements EDW EMMS Extracts Transition to new data archive Network Model Management System (NMMS) Improve Planning and Operational model consistency Improve data submittal interface between ERCOT and Market Participants Improve links between the Model and Outage Scheduler Active (at least in Initiation)

  6. Market Notice of LaaR Proration PRR 558 Before a floor of zero bid limit was established (negative bids were allowed) Breaker to Breaker One Lines/System Map NERC Audit stated that ERCOT needed a visual wide-area display to continually provide the operators with an overview of the entire ERCOT system The ability to quickly trace flows & problems for a transmission element from one breaker to the next Improvements to VSA/DSA – Phase II Automates the data input necessary to include transient stability studies as part of the real-time sequence SCR 747 – Removal of Price Administration for Zonal Congestion Newly initiated project MOMS PUC Study SPD enhancements EMS Upgrade Current HW reaching its lifespan ERCOT EMS current server and OS platform not compatible with AREVA roadmap AREVA support philosophy on the “old versions” No standard support for releases that are either 4 years old or two releases behind New functionality and applications to support Market Redisgn Security enhancements in the new AREVA development SCR 746 Dynamic Rating Data to TSP Using ICCP Link AIMMS 3.6 Necessary for MOMS and ERCOT Market System AVR Validation NERC Audit Item New or Not Started

  7. Single ITEST Environment for all EMS Changes Approximately 200 SIRs (MOS,POS & Portal) Weekly Database Loads Market Redesign effort Integration & Resource Constraints
