  2. Agenda • Progress Update • Scope Review • KEMA Assumptions Review

  3. Progress Update • ERCOT contacts for Inventory and Impacts review identified by CBCG • KEMA started to ask these contacts for possible date for meetings over the next 3-4 weeks • Impacts assessment at the process level in progress • Market Participant Surveys ready for distribution later this week

  4. Implementation Impacts Assessment Scope • Quantitative and qualitative treatment of: • Systems Costs • Staffing • Risk Transition • Training • On-going Maintenance & Support

  5. KEMA Assumptions Review • Assumptions: • Classification of Market Participants • Change Case Description/Definition • Confidentiality • Data Gathering • Impacts Assessment

  6. Classification of Market Participants • Market Entities: • ERCOT • Qualified Scheduling Entity (QSE) • Resource Owners (PGCs) • Load Serving Entity (LSE) • Transmission and/or Distribution Service Provider (TDSP) • Why not the 9-segments? • An IOU or Municipal can play multiple Market Entity roles • No simple way to separate by segment and avoid “double counting” • The Implementation Impacts Analysis will provide detailed cost estimates

  7. Market Participant Relationships

  8. Study Market Segments • Nine Market Segments • Investor Owned Utilities (IOU) • Municipally Owned Utilities (MOU) • Electric Cooperatives (EC) • Independent Power Producers (IPP) • Power Marketer (PM) • Retail Electric Provider (REP) • Retail Customer • ERCOT ISO • Public Utility Commission of Texas (PUCT) • Market Segments Costs based on Entity costs

  9. Change Case Description / Definition • Three Change Cases Considered: • 1) Texas Nodal Team (TNT) • Defined in Concept (White) Papers • Detailed in Draft TNT Protocols • CBCG to identify SMEs and Contact Information • 2) Nodal Light • Defined in Change Case Summary • Additional information may be needed • CBCG to identify SMEs and Contact Information • 3) NE-ISO Replication • Defined in Change Case Summary • Additional information may be needed • CBCG to identify SMEs and Contact Information

  10. Confidentially • Information may be available in the public domain • KEMA will: • Maintain strict confidentiality of any identified competitive information • Remove identity for use in the corresponding generic Entities results • Review and Sharing of Information with: • Cost Benefit Concept Group (CBCG) • Texas Nodal Team (TNT)

  11. Data Gathering • Data Collection for: • Existing and planned (~1yr) Hardware expansions • Existing and planned (~1yr) Applications expansions • Staffing, Training, and Support Cost Data • KEMA will use other sources of data such as: • Historical organization experience • Current costs from surveys and inventories • Vendor estimates • Market research and publications • Analyst judgement

  12. Data Gathering • Market Participant Survey (See handout) • Market Segment Representative Roles/Responsibilities: • Act as key liaison/contact for other Market Participants • Assist KEMA in monitoring progress of responses • Individual Market Participants • Separate survey completed for each “Role” • Questions on Survey through KEMA/CBCG • TWO weeks allotted for responses – due by June 18

  13. Data Gathering • ERCOT Information • Existing Systems, Applications, and Staffing • Planned expansions or changes prior to Nodal Market 2007 • Clearly identify Nodal Drivers for Nodal Market 2007 • KEMA will analyze, sort and compile the surveys • Generic Market Entities systems • No substitutes or proxies for missing data responses

  14. Data Gathering – Process Summary

  15. Impacts Assessment • Implementation Impacts Assessment • By Market Process Timeline • New Nodal Business Process Derived from Change Change Cases description: • Pre-Day Ahead Activities • Day-Ahead Activities • Adjustment Period and Operating Period Activities • Real Time • Post-Operating Day Activities

  16. Impacts Assessment - Process Summary

  17. Deliverables – Implementation Impacts • Preliminary outline and results (~summer) • Summary of Impacts • Summary of costs • Major cost drivers and cost risks • Treatment of other major risks • Qualitative impacts • Detailed cost spread sheets (Excel workbook format) • For ERCOT • For Market Participants, based on reasonable categorization of market participants
