Technical Advisory Committee (TAC) Update
Annual TAC/Subcommittee Structural and Procedural Review
Mr. Bern related discussion at the annual TAC/Subcommittee Structural and Procedural Review, and conveyed requests that, to the extent possible, working group and task force meeting agendas be posted and distributed the customary seven days ahead of meetings, and updated as necessary to incorporate additional assignments. Mr. Bern also related discussion regarding removal of the non-reporting groups Critical Infrastructure Working Group (CIPWG) and North American Electric Reliability (NERC) Reliability Working Group (NRWG) from the Reliability Operations and Subcommittee (ROS) structure to the Other category, similar to the Regional Planning Group (RPG.)
Regarding ROS meetings, Mr. Bern noted that the practice has been to cancel meetings with light agendas. Mark Soutter added that some concern was expressed regarding opportunities to thoroughly vet issues and hold timely votes on items referred for ROS consideration, but that committees should not meet unnecessarily. Mr. Bern suggested that consideration be given to WebEx information sessions and email votes, when agendas warrant.
