ERCOT's Texas Nodal Team requests ROS to evaluate the readiness of ERCOT NM/SE for Texas Nodal operations. TNT proposes criteria and procedures for testing, updating, and maintaining NM/SE databases, functions, and applications. They also seek ROS assistance in achieving readiness timelines and reporting to TAC regularly. ROS will identify criteria for testing NM/SE readiness and operational contingency procedures. They will also seek collaboration with other TAC subcommittees and task forces to ensure the reliable operation of the grid under the Texas Nodal design.

Network Model & State Estimator Readiness For Application in Texas Nodal F. John Meyer December 4, 2003 ERCOT TAC Meeting Presentation
Background Texas Nodal conceptualization has assumed: The availability of a detailed network model (NM); A fully tested state-estimator (SE) Foundation of Texas Nodal market design The Texas Nodal Team requests the Reliability Operations Subcommittee (ROS) evaluate the readiness of ERCOT NM/SE for commencement of Texas Nodal operations
NM/SE ReadinessTNT proposes that ROS Identify/Evaluate: Criteria for testing and proving NM/SE ready Network Observability; Telecom & Computer System Reliability Convergence Rate; Solution Speed; Mismatch Tolerance; and Other criteria deemed necessary Programs for testing NM/SE-related system interfaces, functions and applications as ready Procedures for on-going maintenance, update and improvement of NM/SE database, applications and functions
NM/SE ReadinessTNT proposes that ROS Identify/Evaluate: Procedures to update NM without interrupting the 5-minute calculation of LMPs Procedures and functions to make NM available to market participants; including NM updates Operational contingency procedures addressing SE non-convergence, functional failures and system or telecommunication failures; and related notices to market participants
NM/SE ReadinessBetween Now and Texas Nodal Market Implementation, TNT Requests ROS: Identify, for TAC, the assistance ROS requires from other TAC subcommittees and task forces, if any, to achieve the Texas Nodal readiness timeline Periodically report to TAC on NM/SE readiness Make any other reports or recommendations to TAC that ROS believes necessary for the reliable operation of the grid under the Texas Nodal design
