Branden Sudduth Director, Reliability Assessment and Performance Analysis Planning Coordinator Gap Update March 25, 2014 PCC Meeting – Salt Lake City
Planning Coordinator Gaps Issue • Perceived reliability risk because: o Several entities do not know who their Planning Coordinator is or mistakenly assume another entity is performing this function for them o There is a lack of clarity in Functional Model around who should be a Planning Coordinator o There is no clear definition of a Planning Coordinator Area o There may be reliability functions not being performed 2
Events Creating Urgency • MOD-032 Standard Development o Passed final ballot in December 2013 o NERC Board approval February 2014 o Requires data providers to submit power flow, dynamics, and short-circuit data to their Planning Coordinator and Transmission Planner 3
