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
  • 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
  •  

8
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.

9
168-Hour Test Breakdown of Activities Evaluation
Criteria
  • Evaluation Criteria was agreed on in coordination
    with the Market at the NATF and TAC forums
  • Evaluation Criteria will be reviewed holistically
    in that no one issue from this list will
    necessarily constitute a failure of the test
  • Evaluation Criteria is included in the Appendix
    of this presentation and in the 168-Hour Handbook

10

168-Hour Test Breakdown of Activities
Preparation Activities
  • Network Model Load
  • 09/01/2010 Network model to be used during the
    168-Hour test loaded to the Nodal Production
    Environment
  • Going forward the network model loads will
    generally follow the Zonal schedule
  • Data from Market Trials Phase 5 to be used in the
    168-Hour test
  • To the extent necessary to support settlement and
    credit operations, ERCOT will use estimated
    and/or settled data from Operating Days in July
    and August from MT5 as well as the CRR inventory
    from the September CRR auction (see above) during
    the 168-hour test.

12
Nodal Production Environment
13
Nodal Production Environment
  • During the 168-Hour Test, applicable Nodal
    systems will be managed as if the systems were
    fully in production 7x24, exercising the same
    procedures used for Zonal production operations
  • Change Controls during and leading up to the test
    shall adhere to a similar SLA as Zonal Production
  • If an outage is required, a Market Notice will be
    issued and determination will be made if this
    will require a restart of the 168-Hour test

14

168HR Supporting Materials
20
Evaluation Criteria
  • Validate ERCOT and Market Participants have the
    proper resources and expertise to manage a Nodal
    system for 7 days. This will be measured by the
    successful adherence to internal ERCOT procedures
    during the 168-Hour test to be validated by the
    ERCOT Training Department during the test and
    evidenced to the market within a report. Market
    Participants Nodal Accountable Executive will
    self attest to their criterion.
  • Credit monitor credit exposures, create credit
    reports and accurately reflect each market
    participants credit position based on their
    activity during the 168-Hour test.
  • Validate data model accuracy between all systems
    including integration of the upstream NMMS system
    with downstream systems (e.g. DAM, MMS, EMS and
    CRR). This will be measured by existing ERCOT
    procedures. All issues observed regarding
    inaccurate modeling during the 168-Hour test will
    be reported on by ERCOT to the ERCOT Board,
    Independent Market Monitor, and the related
    Market Participant forums (NATF and TAC) as to
    the problem found, root cause of the error in the
    first place, and what process changes are being
    implemented to ensure that similar model accuracy
    issues do not reoccur going forward. ERCOT shall
    attest to the data model accuracy in and between
    all systems as a result of TSP and Resource
    Entity data passing the ERCOT validation rules.
  • Execute DAM, DRUC, HRUC and WRUC for 7 days
    within timelines set by Nodal Protocols. If any
    activities fall outside of expected timelines,
    procedures for handling such incident must be
    executed by ERCOT personnel in adherence with
    Nodal Protocols and internal ERCOT procedures.
  • Verify RT Operators can maintain system frequency
    to scheduled frequency, maintain ancillary
    obligations and resolve constraints during the
    period in which ERCOT will be performing Full
    System Market and Reliability tests during the
    168-Hour Test.

21
Evaluation Criteria
  • Validate ERCOT can effectively and accurately
    manage all constraints in both DAM and RT (i.e.
    not constrain on invalid contingencies or
    inaccurate line ratings) and system will utilize
    full list of competitive constraints.
  • Validate that ERCOT can execute and manage all
    SPS, RAPs, PCAPs, MPs, and TOAPs to control
    congestion in the DAM, DRUC, HRUC, and RT as
    appropriate.
  • Validate that ERCOT is accurately reflecting all
    congestion mitigation measures (SPS, RAPs) in
    DAM.
  • The rolling CPS1 one minute average score must
    equal or exceed 100 during the Full System
    Market and Reliability test period. The target
    minimum is 125.
  • Note that the CPS1 average will not take into
    account the two one-hour periods when ERCOT is
    transitioning to Nodal and then back to Zonal and
    any periods in which ERCOT must deploy RRS in
    response to system contingencies.
  • Zonal Commercially Significant Constraints (CSCs)
    and Closely Related Elements (CREs). managed
    below thermal limits.
  • Local Congestion managed below thermal limits.
  • Stability limits managed below transfer limits.
  • No NERC Disturbance Control Standard (DCS)
    failure if applicable.
  • No LFC-SCED system issues that result in
    termination of the test.
