The PLWG could not reach consensus on PGRR011 but was in agreement to forward PGRR011 as amended by the 9/1/11 Luminant comments and as revised by the PLWG to ROS
This Planning Guide Revision Request (PGRR) provides clarifications and additions to the transmission planning criteria to address the gap between operations and planning processes in order to develop adequate transmission capacity to minimize the likelihood of unmanageable constraints (i.e. Security-Constrained Economic Dispatch (SCED) irresolvable constraints) being encountered in Real-Time.
Reason:
TAC has directed ROS to develop planning processes that eliminate the gap between operations and planning in order to significantly reduce the amount of unmanageable constraints that have been observed in Real-Time. It is recognized that unmanageable constraints in Real-Time can arise for a variety of reasons, only some of which may be improved with these transmission planning recommendations; while many of the others may be improved with operational planning enhancements. This PGRR represents the recommended modifications to the transmission planning process. A companion set of recommended modifications that were identified for the operational planning (i.e., Outage approval planning and Reliability Unit Commitment (RUC)) process have been submitted under Nodal Protocol Revision Request (NPRR) 409, Outage Planning Criteria Clarifications and Enhancements to Narrow Gap Between Real-Time Operations and Outage Planning, and Nodal Operating Guide Revision Request (NOGRR) 078, Real-Time Security Analysis Language Clean Up to Reconcile Operating Guides with Current Operation Practice.
