Lead from the front Texas Nodal http://nodal.ercot.com 1 Single-Entry Model Milestone Status Report May 1, 2008
Lead from the front Texas Nodal http://nodal.ercot.com 2 ERCOT Anti-Trust Admonition ERCOT strictly prohibits Market Participants and their employees who are participating in ERCOT activities from using their participation in ERCOT activities as a forum for engaging in practices or communications that violate the antitrust laws. The ERCOT Board has approved guidelines for members of ERCOT Committees, Subcommittees and Working Groups to be reviewed and followed by each Market Participant attending ERCOT meetings. If you have not received a copy of these Guidelines, copies are available at the Client Relations desk. Please remember your ongoing obligation to comply with all applicable laws, including the antitrust laws.

Lead from the front Texas Nodal http://nodal.ercot.com 4 3 The focus of this status report is on the following area…. For Single Entry model Go Live we are focusing on NMMS the tool, NOMCR capability, and the EMS CIM importer 1234
Lead from the front Texas Nodal http://nodal.ercot.com 5 What is Single Entry Model Go Live? The ERCOT NMMS tool is deployed to production. TSPs will use the ERCOT NOMCR process to submit network model changes to ERCOT. TSPs will no longer submit Service Requests for zonal network model changes (unless agreed to with ERCOT Network Modeling Group). ERCOT will enter NOMCR-submitted changes from TSPs into zonal Genesys modeling system (ERCOT dual entry). QSEs w/resources will continue to submit RARFs; ERCOT will submit NOMCRs on their behalf. ERCOT will generate and maintain the NMMS ERCOT CIM model.
Lead from the front Texas Nodal http://nodal.ercot.com 6 Single Entry Model is Not… Confirming that all nodal systems (EMS, MMS, OS, etc) are interpreting CIM data correctly and results are consistent –This will be an iterative process performed after Single Entry Model Go Live and before the 168-hour test. Does NOT enable TSPs to use the ERCOT planning model change requests –Planned as a future ERCOT NMMS release, coordinated with TSPs
Lead from the front Texas Nodal http://nodal.ercot.com 7 Moving forward with Section 21 as governance… Protocol 21.12.3Notice to Market Participants of Effective Date for Nodal Protocol Provisions and Retirement of Zonal Protocol Provision No part of the nodal market design may start operation until all the Market Readiness Criteria for that part of the nodal market design have been met. Certification that all Market Readiness Criteria have been met must be made at least by each of the following: the Transition Plan Task Force (TPTF), TAC, ERCOT Staff and the ERCOT Board. Upon such certification, ERCOT shall issue two Notices alerting Market Participants to the effective date of Nodal Protocol sections and the retirement of Zonal Protocol sections, as applicable. ERCOT shall issue the first Notice no less than thirty (30) days prior to the effective date or retirement date, as applicable, and the second Notice no less than ten (10) days prior to the effective date or retirement date, as applicable. The Notice shall include: (1)The Nodal Protocol Sections to become effective and (2)The Zonal Protocol Sections to be retired, if any.
Lead from the front Texas Nodal http://nodal.ercot.com 8 Single Entry Model Go Live Entrance Criteria Complete and Consistent Nodal Model –Ability to import NMMS ERCOT CIM and successfully execute EMS applications –Database/application result comparison between zonal network model and nodal network model NMMS Market Trials Completed NMMS Sev 1 and Sev 2 Defects Resolved NMMS Certification Approval –Internal & External Staff Approval Transition Plan Task Force (TPTF) TAC ERCOT Staff ERCOT Board –Issue Market Notices (30 day, 10 day)
Lead from the front Texas Nodal http://nodal.ercot.com 9 ERCOT’s plan to move forward… Based on the Section 21, ERCOT is not ready to move forward with the related Nodal Protocol The Nodal protocols associated with Single Entry Model Go Live are: –3.10 Network Operations Modeling and Telemetry –3.8 Special Considerations for Split Generation Meters (NOMCRs) –3.7 Resource Parameters (NOMCRs) –3.5.2 Hub Definitions (NOMCRs) –18.104.22.168 Information to Be Provided to ERCOT (NOMCRs) ERCOT is planning to move towards using the tool, and then initiating the certification approval process –NMMS tool deployment for June (assuming issues are corrected)
Lead from the front Texas Nodal http://nodal.ercot.com 10 What this means to you…. ERCOT is not planning to put any Nodal Protocols Live on June 2 nd ERCOT will only start enforcing the Nodal Protocols after Certification votes as per Section 21 Once ERCOT Nodal Protocols are Live –TSPs and QSE w/resources will need to start following the Nodal timelines for the Network Model changes –ERCOT will start posting the Network Model and approved changes –Realization of all the benefits listed earlier Logistically, it means that we are in “production” with our first Nodal solution
Lead from the front Texas Nodal http://nodal.ercot.com 11 Benefits to TSPS & QSEs Establishes the NMMS single-entry process to submit changes to the nodal market several months prior to Nodal December 1 st Go Live Enables TSPs to validate internal processes and procedures prior to Nodal December 1 st Go Live Provides TSPs with the opportunity to establish consistency between internal models and the ERCOT nodal model Provides TSPs and QSEs with visibility of the nodal model and the associated changes

Completion of this training enabled the TSPs to review the model, make changes as needed and complete model validation as required by the Nodal Transition Plan. Scripts included: –Generate, Post, and Distribute Models and Files –Change Request Submissions –Status Changes –Additional Features –Downloading Change Files Updates to the Market Trial scripts were driven by feedback by participants. This training is scheduled to complete on May 20th.

Topics include the processes, procedures and activities that provide the necessary safeguards in modeling the ERCOT system. To date, the instructor led course has been delivered to 214 attendees. The next course is scheduled for May 21. The market share status of training is “Yellow” based on the fact that QSE’s with Resources and TSPs completing the course.
Lead from the front Texas Nodal http://nodal.ercot.com 21 ERCOT Current Status – NMMS Staffing The NMMS project team consists largely of ERCOT “home team” staff (only 1 consultant) which are involved in development, testing, and training. Therefore this is the same team that will be the business owners of Single Entry Go Live, future CIM testing, and other activities in preparation of the Nodal Market December 1 st Go Live. EMMS Production Support has been engaged in set up of the HW/SW and product releases. Business has hired or has outstanding offers for all open positions IT is working to fill any open position.
