Project #37052

Project to Develop Critical Performance Metrics and Criteria for the ERCOT Nodal Market

Summary

The Staffs of the commission, the Texas Regional Entity (TRE), the Independent Market Monitor (IMM), and the Electric Reliability Council of Texas Independent System Operator (ISO) (collectively, the developers) have jointly developed a list of proposed performance metrics with pass/fail criteria for the ISO, Qualified Serving Entities (QSEs), and Transmission Service Providers (TSPs) for certain functions critical to the reliability of the electric grid in the nodal market structure. The staffs of the commission, TRE, IMM, and ISO have agreed that it is critical to have performance metrics and pass/fail criteria for the functions on this list in place at nodal "go-live." To assist in developing this list of critical performance measures and criteria, the developers used previous work done through the ERCOT stakeholder process, including the work done to date on NOGRR025. The developers have refined, modified, and/or added new information to the prior work products to come up with their list.

After gathering comments from the stakeholder community through a workshop scheduled for June 12, all appropriate revisions will be incorporated into a final version of the list. Ultimately, for items not already covered by protocols, a set of Nodal Protocol Revision Requests with performance metrics and pass/fail criteria based on the final version of the list will be submitted to Electric Reliability Council of Texas (ERCOT) for use in protocols and/or operating guides for the nodal system. Because the submission of the list to ERCOT will be done as an urgent status or other expedited process as appropriate, the developers emphasize that the June 12 workshop is the appropriate and critical opportunity for interested parties to comment.
