Nodal Update for:Single Entry Model (SEM)Go-Live TransitionNDSWGMay 19, 2009Matt Mereness


SEM Go-Live Transition Update

• SEM updates– SEM Overview moved to Appendix

• Schedule review • Communications with stakeholders• Training Update• Ownership versus Operatorship • SEM Go-Live Criteria• Metric Discussion (NOMCR training & submission)• Processes/Submissions during June-Aug’09 transition• RARF Follow-up on validation


SEM updates • Today’s NMMS 6 Status:

– NMMS 6 was released from FAT on 4/30/09– NMMS 6 was loaded into Nodal iTest on 5/13/09; anticipate exiting N-iTest

end of month.

• Issue escalation to TAC/ROS/WMS– Model posting issue- disclosure of Resource data (TAC/ROS/WMS)

• May 7 TAC direction to work with ROS and WMS on Resource data• May 14 ROS and May 18 WMS direction to:

– Consider posting CIM model only to TSPs in the interim (too much zonal market left)– Long-term concern with PUN/Load Profile data being in CIM file– Consider posting “clean” CIM file without Resource data for all MPs

– SEM Go-Live approval without TPTF• Initial direction to have ROS replace TPTF approval• TAC chair asked to defer to next month discussion

– Both would be changes to SEM Go-Live Procedure• Consideration if Board approval is required


SEM updates (continued)

• Communication– May 6th to 15th TSP outreach through Wholesale Client Services

• TDSP/TO associations sent to 23 TOs• Solicit training headcount from TOs (pre and post Go-Live)

• Testing/Training will only include Level 1 Validation• Level 1 – Automatic by the system upon submitting.• Level 2 – Visual by the N/W Model Coordinator• Level 3 – Power flow run on the one NOMCR.• Level 4 – Power flow run on all NOMCRs for that day.• Level 5 – Power flow run on the AREVA system.

Training (continued)


Ownership vs Operatorship Issues Discussion• Friday, May 15 meeting

• ERCOT, MP-Volunteers (D.Bogen, C.Crews, Ebby John, Hill Brady)

• Discussion highlights• Ask ERCOT to provide how RARF Owner/Operator will be reflected in

NMMS when entered by ERCOT• Ask ERCOT to provide downstream consumption of Owner/Operator

NMMS, Outage Scheduler, Telemetry metrics• Should ERCOT consider recognition of Owner/Operator in Protocols 3.10 as

the TO in the Operating Guides• Concern with equipment owners that are unregistered-at-ERCOT being in

conflicting with NERC standards• Whether NMMS reporting could reflect a category of unregistered Owners

for reporting• Consider if early NMMS reports are “draft”• Questioned and answer that NMMS supports:

• Multiple Owners (percentages can be assigned) and single Operator


SEM Go-Live Criteria• SEM Go-Live Criteria defined in the SEM Go-Live Procedure

http://nodal.ercot.com/readiness/golive/index.html• Section 4- The following entry criteria shall be met for SEM Go-Live

– TSPs & ERCOT complete EDS 2 Release 4 activities (next page)– Nodal network model validated and approved as baseline for SEM Go-Live

by ERCOT System Ops and Market Ops Directors– ERCOT publishes CIM model to be used for SEM Go-Live– ERCOT sufficiently staffed for maintenance of nodal & zonal systems– Nodal EMS is capable of consuming NMMS CIM files through the EMS CIM

importer for use in the Nodal EMS application suite– SEM Go-Live readiness approved by TPTF, TAC and ERCOT BOD

• presume ROS approval in place of TPTF

– ERCOT publishes the following documents for TSPs• ERCOT Network Operations Model validation whitepaper• ERCOT Network Operations Model validation results• NMMS Modeling Guidelines / Validation Rules document• Latest CIM data dictionary and schema


SEM Go-Live Criteria (cont’d)– All TSPs complete EDS 2 Release 4 activities

• MPs have enrolled and can access the ERCOT MIS portal• MPs have been trained on the NOMCR process• TSPs can electronically submit data changes utilizing the NOMCR user interface and CIM

compliant format for data exchange or via the manual MIS NOMCR process• QSEs can submit data changes utilizing the registration submission and subsequent ERCOT

NOMCR process• MPs can receive NOMCR acknowledgement of submittals, verifications, and confirmation of

data posting

– ERCOT completes EDS 2 Release 4 activities• ERCOT is ready to fully utilize the NOMCR process for all TSP/QSE data change requests• TSP MPs can successfully submit data changes via the CIM compliant electronic NOMCR

process. • QSE can successfully submit data changes through registration submissions (and updated in

the Network Operations Model via the NOMCR process)• ERCOT has processes in place to use a “single entry point” to maintain both Nodal and

Zonal network model databases when MPs submit changes via the NOMCR process• NMMS is the database of record for the Network Operations Model including the ICCP

modeling point database and operatorship / ownership information• NMMS database is under full change control by ERCOT Network Model Group• ERCOT discontinues the use of Service Requests for data changes and change control• ERCOT begins the use of the NOMCR process for data changes and change control


Metric Discussion

MP14 – B – MP EDS-2, Release 4 Trials Participation

Reported By: TSP

Target Completion: Single Entry Model Go-Live minus 30 Days

Category: Trials Participation

Metric Description: This metric evaluates the level of TSP market participant participation in the EDS 2, Release 4 Trials.

Background: The intent of this metric is to ensure that Market Participants are actively participating in the NOMCR process.

Criteria: The Readiness Team will review documentation that an adequate number of TSPs have submitted modifications through the NMMS tool following the NOMCR process.

# of TSP MPs Participating in Trial participating in the NOMCR process >= 95%RAG Rules - MPs

Red - Not participating in trialsAmber – Not ApplicableGreen – Meeting criteria

Metric Discussion (continued)MP13 – MP Completes Nodal Operations Related TrainingReported By: QSER, QSE, TSP

Target Completion: Cyclical in preparation for the 168-Hour Test and Go-Live transition sequence

Metric Description: Market Participants complete the applicable training modules associated with nodal operations related readiness

Background: The intent of this metric is to ensure that Market Participants participating in Nodal have adequate knowledge of the Nodal Operations to participate

Criteria: The Readiness Team will review self-reporting from each Market Participant indicating their level of training necessary to assure the Market Participant’s ability to successfully operate in the Nodal Market meets the scope of activities described in the ERCOT developed Training Materials included in the following courses.Basic Training Program;Non-Opt In Entity NOIE (QSE) Operations;Generation 101;Transmission 101; Network Model Management; ERCOT 101 for Wind Generation.

Processes/Submissions during June-Aug’09 transition– Does NDSWG agree with this approach, and is approval needed?

– Transition periods:• June 1- Aug 30, 2009 (objective to minimize SvcReq during this period)

– No equipment name changes (defer until after SEM Go-Live 8/31/09) – Submit changes as far in advance as possible

• Aug 15-30, 2009– Two weeks no submissions, except for emergency changes

• Aug 31, 2009 - Feb 2010 (NOMCRs for any/all network changes)– Initially the NOMCR timeline will align with zonal timeline

» NOMCRs received and translated to zonal model change » 30-day lead-time, compliant with current zonal database schedule» Status is tracked and communicated via system emails

– SRs that did not go into zonal production will be converted to NOMCRs for verification and submission by TSPs in Sept

– TSP gradually transitions to NodalProtocols(3.10) 90-day reqts


RARF follow-up on validation

• Follow-up from previous NDSWG regarding validation rules for RARF– Resource Asset Registration spreadsheet files are submitted by Resource

Entities via a Service Request (this will not change in Nodal)– Validation steps:

– Limited enforcement in Excel file (drop-down fields)– Submission screening process

– RARF visually reviewed by Client reps for completeness– Audit process executed to enforce 1800 business rules

– Example Low Limits <= High Limits– ERCOT has matured process and posting validation rules for

current and future Planning and Transmission submissions– Plans to go-back after current RARF activities and create

market-facing validation rules by end-of-year– If issues found, RE contacted for correction

– Submission into NMMS subject to Network Modeling Guidelines
