  7. 168-Hour Test Breakdown of Activities: Objective / Participation Requirements • Objective • Conduct a full rehearsal of the Nodal Day-Ahead Market (DAM), Reliability Unit Commitment (RUC), Real Time Market and Load Frequency Control (LFC) • Continuous seven day period of Market Systems and 48 hours of Closed Loop LFC • Components required and to be exercised during the 168-Hour test: • The Day Ahead functions including DAM, DRUC, HRUC and WRUC • The Real Time systems performing SCADA, Network Security Analysis, Transmission Constraint Management, SCED, and LFC • The Nodal support systems including Network Model Management, Outage Scheduler, Outage Evaluation tools • Credit Monitoring and Management (CMM) • Settlements and Billing • Posting of applicable Reports and Extracts Technical Advisory Committee

  8. 168-Hour Test Breakdown of Activities: Objective / Participation Requirements • Participation Requirements: • The value of the 168-Hour Test is dependent on participation by the Market. • The 168-Hour Test is required by all registered Market Participants intending to be involved in the Nodal Market • Participation data and metrics will be published and made readily available to the ERCOT Board, Independent Market Monitor and the related Market Participant Forums (NATF, TAC) • Metrics will also include comparisons of Zonal Resource Plans to Nodal COPs. • Participation should be reasonably reflective of post Go-Live behavior Technical Advisory Committee

  9. 168-Hour Test Breakdown of Activities: Entry / Exit Criteria • Entry Criteria for the 168-Hour test will be as follows: • All defined Market Trials Testing up until the 168-Hr test has been completed in accordance with the Market Trials Handbooks published to the Nodal Readiness Center • ERCOT declares readiness for initiating the 168-Hour test to TAC and the Board and obtains director level sign off from ERCOT management. • Exit Criteria: • 168 hours of continuous Nodal systems testing have been completed without encountering any major system issues that would prevent the Nodal Market from going live while maintaining system security and reliability as required by the ERCOT Protocols, Operating Guides, other binding documents, and NERC Reliability Standards. • ERCOT provides a test summary report to TAC and the Board outlining the successful testing processes. Technical Advisory Committee

  41. Appendix Technical Advisory Committee

  42. Defects, Issues, Quality of Solution: Definitions • Defects: • A technical error or problem between ERCOT’s internal system or between ERCOT and the market • Deferred defects are Severity 3 defects, that have been deferred until after Go-Live, but have a confirmed workaround in place • Quality of Solution: • Data Issues: • Heavily dependant on inputs • No significant software issues • On-going analysis of results and inputs • Performance Issues: • ERCOT is constantly looking to improve performance • Monitoring in place to detect issues • Known Issues / Market Facing Issues • Issues uncovered during internal or market trials that impact Market Participants Technical Advisory Committee

  43. Nodal Program Risks & Issues: Definitions Definitions for Category, Probability and Severity of Risks & Issues: • Category • Scope : Will require a scope change • Schedule: Will require a schedule change • Budget: Will require a budget change • Probability • High : Probability to occur is ≥ 90%; perceived impact would require a Change Request over the next 1-3 months • Medium: Probability to occur is between 31 – 89%; perceived impact would require a Change Request over the next 4 -10 months • Low: Probability to occur is ≤ 30 %; not expected to require a Change Request • Severity • High: Milestone impact, or budget impact >$250,000 • Medium: Milestone impact - but expected to be mitigated, or budget impact between $0 - $250,000 • Low: No milestone impact, or no budget impact Technical Advisory Committee

  44. Readiness Criteria – Metrics by Area (Planned, Active, or Complete) • 75 metrics are considered to be Readiness Criteria for TAC, BOD Go-Live votes • All of these metrics are considered as “Readiness Criteria” that will be included in TAC/BOD Go-Live votes. • Once a Readiness Area is approved for Go-Live, metrics falling within that Readiness Area will be considered complete • * 26 Complete include the 19 newly completed metrics on Slide 3 Technical Advisory Committee

  45. Readiness Criteria – Completed Metrics • ERCOT has 19 newly completed nodal metrics • 7 Metrics related to TAC/Board have signed off (NMMS, OS, and CRR). • 5 EMS metrics • 7 Metrics for general readiness Technical Advisory Committee

  46. Readiness Criteria – From now to Go-Live 24 Metrics not yet active, but still planned to be measured before Go-Live. Technical Advisory Committee

  47. Readiness Criteria – From now to Go-Live (continued) Metrics will be closed as TAC/BOD signoff is garnered for various systems and readiness areas Technical Advisory Committee
