2 Technical Advisory Committee (TAC)
Functions of TAC (ERCOT Bylaws Section 5.2) TAC shall: Through its subcommittees make such studies & plans as it deems appropriate to accomplish the purposes of ERCOT, the duties of its subcommittees and policies of the Board, Report the results of such studies & plans to the Board as required by the Board, Review & coordinate the activities & reports of its subcommittees, Make such recommendations to the Board as it deems appropriate or as required by the Board, Perform such other duties as directed by the Board, and Make recommendations regarding ERCOT expenditures and projects.

3 Technical Advisory Committee (TAC)
TAC, comprised of stakeholders, makes recommendations to the Board and is assisted by five subcommittees and the Transition Plan Task Force (TPTF): Commercial Operations Subcommittee (COPS) Protocol Revisions Subcommittee (PRS) Reliability and Operations Subcommittee (ROS) Retail Market Subcommittee (RMS) Wholesale Market Subcommittee (WMS) Transition Plan Task Force (TPTF) Consumers are represented on all committees. Numerous task forces (temporary) and working groups (permanent) reporting to these major subcommittees also meet regularly. Current TAC and subcommittee structure developed in 2000, with the later addition of COPS.

4 High Level TAC Goals for 2007

22 Commercial Operations Subcommittee (COPS)
Responsibilities: Addresses the processes through which ERCOT market data is translated into financial settlements. Helps improve commercial operations by integrating the retail variance and wholesale market settlements processes, including dispute resolution. Commercial operations include the application of load profiles, data aggregation, data extract variances; transmission congestion rights settlements; qualified scheduling entity settlements; invoicing; and dispute resolution. Addresses the settlements calendar; settlement-related performance metrics and tracking; market participant data needs for shadow settlements; and the market's overall needs for data extracts, delivery and presentation.

23 Commercial Operations Subcommittee (COPS): 2006 Accomplishments
