168-Hour Test Measurements


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


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.


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


168-Hour Test Breakdown of Activities: Preparation Activities

• Full System Market and Reliability Tests• The following tests have been completed prior to the start of the 168-Hour tests:

verified by TSPs and QSEs for outages effective for the month of September• 08/30/2010: TSP and QSE deadline to complete synchronization and verification• Market Participants that have not yet completed this should:

• Continue work on this activity• If there are questions or issues, contact ERCOT at [email protected]

• Congestion Revenue Rights Auction• 08/27/2010: ERCOT posted the Auction Results for the September Monthly Auction


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.


Nodal Production Environment


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


168-Hour Execution


168-Hour Execution: Schedule

• September 8, 2010 - 168-Hour Test begins– Day ahead Market will run for Operating Day September 9, 2010 using the DAM ACL sent from CMM – DRUC and WRUC will run per protocol timelines starting the first day of the test – ERCOT will begin running hourly HRUC at 1800 when the Adjustment Period opens.– All Real Time telemetry, and Market Submission shall continue to be submitted by the Market– All postings delivered in previous Market Trials Phases delivered per Nodal Protocol timelines– Initial DAM / RTM statements posted per the Nodal settlements calendar– Production level support, including those systems that are supported 24x7, goes into effect for the duration of the 168-Hour

Test– For the duration of the test, DAM, RUC, Settlements and Credit processes will run per Nodal Protocol guidelines in an open

loop format. Zonal will continue to commit units using the RPRS processes and actual, binding settlements will execute per Zonal Protocols.

• September 12 – September 14, 2010 – Full System Market and Reliability Test During the 168-Hour Test– September 12, 2010 at 2:00 PM, all generation will begin transitioning to Nodal control estimated to be completed by 3:00 PM– The ERCOT grid will run under Nodal Control through September 14, amounting to a total of 48 Hours of Full System Market

and Reliability Testing during the 168-Hour Test– Day Ahead Market, RUC processes and SASM will continue to be executed per Nodal Protocols.

• Zonal will continue to commit units using the RPRS and OOMC processes and actual, binding settlements will execute per Zonal Protocols.– September 14, 2010 all generation will transition back to Zonal starting at 1:00 PM, estimated to be completed by 2:00 PM

• September 14, 2010 – September 15, 2010– ERCOT will continue to run the remaining operating days of the 168-Hour test, executing DAM, RUC, settlements and credit

processes– The final day of the 168-Hour test will be on September 15, 2010

• September 16 or 17, 2010– Special NATF session will be held to review the DAM testing results of the 168-Hour test and determine remaining testing

objectives for Market Trials. RT testing results will be evaluated once RT settlement statements are received.

168HR Supporting Materials


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 Participant’s Nodal Accountable Executive will self attest to their criterion.

• Credit – monitor credit exposures, create credit reports and accurately reflect each market participant’s 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.


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.

• The 168-Hour test will provide adequate data to set the GREDP/CLREDP performance. criteria variables X, Y, and Z. ERCOT shall produce appropriate reports that can be used to set these variables.

• Bilateral trades are processed and flow through the market systems with results returned to MPS.

• Outputs from the Day Ahead Market, Reliability Unit Commitment, and Real Time Market can be reasonably explained based on the inputs.

Nodal Cutover and Market Transition – Communication Plan

Friday Market Calls Starting 09/03/2010 at 9AM-12noon these calls will be combined, without breaks, into a single Market Trials and Cut-over Activities call

Market Participants should plan on attending the full duration of this call as it will provide the primary means of communication between ERCOT and the Market.

Information and materials covered in this call will continue to be posted to the ERCOT calendar website every Friday at the following URL: http://www.ercot.com/committees/nodal/mt/

Monday Kick-Off Calls As needed to review the cutover activities for the week

Market Notices and Market Participant Contact ListsERCOT will continue to leverage Market Notices to communicate pertinent information that is required to be consumed by the Market as a whole.

Market Participants employees can subscribe to the Market Notices on the ERCOT Lists website at the following URL: http://lists.ercot.com/scripts/wa-ercot.exe?HOME.Market Participants may verify their contact information on file with ERCOT through their assigned Whole Client Services Representative.

Nodal Cutover and Market Transition – Communication Plan (Cont.)

Market Participants Contacting ERCOT

•Market Trials email inbox: [email protected]. This inbox will continue to be maintained throughout Nodal Cutover. This will serve as a “catch-all” forum for questions if there is any doubt as to where a question should be submitted.

•Friday Market Calls: In line with the previously mentioned schedule, these Market Calls not only serve as the primary means for ERCOT to communicate to the Market, but also for MPs to field general questions concerning the Nodal Cutover plan.

•ICCP email inbox: [email protected] for specific MP questions regarding their Nodal ICCP / Telemetry, this email address should be leveraged for the fastest response.

•ERCOT Wholesale Client Services Account Manager: Whenever possible MPs should leverage the Market Trials email inbox, however, MP’s Wholesale Client Services Account Manager will also be equipped to either answer your questions or route you to the correct support personnel.

•Nodal Advisory Task Force (NATF): NATF will serve as a forum for initially reviewing changes in activities during the ERCOT Nodal Cutover, NPRRs and any concerns from the Market that would impact the overall Cutover plan. To that end, NATF will be meeting more frequently to ensure expedient coverage of these types of issues. Details regarding meeting agendas and materials from past meetings will continue to be maintained at the following URL: http://www.ercot.com/committees/board/tac/natf/

Nodal Cutover and Market Transition – Reversion Plan

Reversion Plan Approach:

•12/01/2010 – 12/02/2010: Zonal and Nodal systems continue to process in parallel. This allows for 48hrs of stabilization (2 Operating Days) with parallel processing similar to the level of effort being performed with the LFC Testing

•12/03/2010 – 12/31/2010: Zonal systems “Retire” where processing is disabled, but remain in place in the event they are needed to be reinstated quickly.

•01/01/2011: Zonal System Decommissioning begins
