3 SEM Go-Live Market Criteria Status (as of 8/17/2009) Notes- ERCOT working one TSP to catch-up on final testing/training - TSP has signed up for Sep 29 th make-up training and submitted a test NOMCR - ERCOT will support this TSP (and any other TSP) with assistance in submission of NOMCRs

4 Overall SEM Go-Live ERCOT/Market Criteria Dashboard Summary of Criteria from TAC-approved SEM Go-Live Procedure ( )

7 APPENDIX What is SEM Go-Live? Training Update Transition summary during June – August 2009 August implementation summary

8 SEM Go-Live Overview Single Entry Model (SEM) Go-Live is the switchover on Aug 31, 2009 for TSP submissions of network operations model change requests –from “Service Request” submissions via TML –to “NOMCR” submissions via the NMMS System of record for model changes becomes NOMCRs on 8/31//09 System of record for Network operations Model for reliability and dispatch remains Zonal/Genesys system until Dec 2010 TSP Current Activity Submit Modeling Change via Service Request ERCOT Uploads Svc Request into Zonal Genesys Model ERCOT Copies/Converts Zonal Model “seed” Into Nodal NMMS Model TSP Aug 31, 2009 Submit Modeling Change via NOMCR/NMMS Tool (includes ICCP) ERCOT Incrementally Converts NOMCR Into Svc Req Uploads into Zonal Genesys Model ERCOT uploads NOMCR Into Nodal NMMS Model to support nodal testing Data Consistency Checks are run to ensure model synchronization/fidelity Periodic checks are run to ensure model synchronization/fidelity Full Copy Incr. NOMCR

9 Current Network Operations Model Maintenance for TSPs ERCOT Zonal EMMS Model (system of record through 12/1/2010) Submits Service Request to Change Model ERCOT Nodal NMMS Model (nodal testing model- CIM file for EMS/MMS/etc) Periodic full copy and conversion of model (zonal seed used for nodal systems) TSP

10 After 8/31/2009: SEM Go-Live Network Operations Model Maintenance for TSP ERCOT Zonal EMMS Model (system of record through 12/1/2010) ERCOT Nodal NMMS Model (nodal testing model- CIM file for EMS/MMS/etc) ERCOT enters NOMCRs into zonal model ERCOT runs consistency checks to ensure models are aligned and maintained Submits Model Change Request (NOMCR) TSP NMMS Model System of Record Nodal Go-Live 12/1/2010

11 Network Operations Model Maintenance for Resource & QSE (today and post 8/31/09) ERCOT Zonal EMMS Model (system of record through 12/1/2010) ERCOT Nodal NMMS Model (nodal testing model- CIM file for EMS/MMS/etc) ERCOT enters into zonal model NMMS Model System of Record Nodal Go-Live 12/1/2010 Submits RARF (Resource Asset Reg Form) via Service Request Submits ICCP Change via Service Request ERCOT process QSE RE

12 Training Update TSP Testing and Training environments will be the same Testing system access –Available June 8 – Aug 28 –NOMCR testing system will be on-line and available to all TSPs –ERCOT will established dedicated and have staff available to support questions Instructor Led Training to be hosted in Taylor –Pre-SEM classes June 22 – Aug 3 Current plans for at least six 3-day sessions Planning for seats for each class Large dedicated training room –Post-SEM classes Sept 29 Fewer sessions Make-up classes, not just-in-time training for all staff after go-live

13 Transition summary during June-Aug’09 –Currently no limits on submissions (Market Notice sent March 5) “… to clarify that there are no restrictions or “freezes” currently in place limiting network model change submissions via the service request process.” –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, 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 schedulezonal database schedule »Status is tracked and communicated via system s –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

14 August implementation activity summary Engagement will shift gears from training to cut-over activities: –TSP coordination for access to production systems –ERCOT completes analysis and posting of key artifacts/analysis CIM Audit, Consistency Check, Rules Validation Final versions of user support documentation Modeling Guidelines final review at NDSWG Posting of CIM schema and data dictionary How-to for granting access to systems –ERCOT to continue to test systems and ensure Service Level Agreements met 99.9% availability of system 4 hour recovery time Support 25 concurrent modeling users Stress testing to continue focus on system performance –July 31 Market notice sent reminding TSPs that no modeling Service Requests should be submitted after Aug 15 to allow synchronization of models Emergency modeling changes will be accepted with approval from Director of Grid Operations
