OPSTF Issue 12(a): Develop Future Year Seasonal Cases in DSB

  1. This Discussion item Scheduled for 9:45 to assist Julius Availability to Participate in Discussion
  2. Comments from Julius Horvath:
  • SSWG did not want to make a permanent revision to any procedure, Planning Guides or SWWG Procedure Manual, regarding the future seasonal base cases until we saw the actual use/need of the initial set of cases that were developed last Fall.
  • Currently DWG is utilizing these cases to develop a future year seasonal dynamic case and I know that some of the TSPs are also utilizing these cases for future year studies, mainly look at voltage requirements.
  • I will place this item on the next SSWG conference call agenda, scheduled for April 3, 2013, as a discussion item to get a feel for how the SSWG feels about pursuing this as a permanent addition to the annual case building.
  • Due to other PGRRs that are being routed through the approval process at this time, my plan was to finalize SSWG Procedure Manual changes by the SSWG at our next Business Meeting, which is tentatively scheduled for June 12, 2013, so we would be looking at ROS approval in July.
