3 WIT Contract Ownership o 2014 IA agreement & WIT agreement were assigned to Peak, following bifurcation o ISAS was approached by Peak in fall of 2014 requesting an opportunity to discuss ownership of the WIT contract  Removal of IA from NERC standards in October 2014 created opportunity for discussion regarding ownership o ISAS held special webinar in November 2014  At time of discussion, contract was owned by Peak but WECC continued to maintain administrative functions WIT Contract

4 Options for Ownership 1.Peak retains ownership of WIT but takes all administrative functions WECC had been performing Requires additional Peak FTE to take on administrative fuction. 2.WECC takes ownership of contract and retains all administrative functions 3.Group of BA’s take ownership of WIT contract WIT Contract cont’d

5 Recommendation  ISAS recommended that WIT contract continue to remain with Peak  Peak will need to hire an FTE or assign an FTE to take over administrative functions  Transfer of all WIT activities to Peak is anticipated to be complete by end of 2015  Peak RC is evaluating the idea of creating a WIT user group to provide interconnection members with a way to discuss issues & address enhancements WIT Contract cont’d

10 November of 2014 WECC hosted one day workshop to discuss Dynamic Transfers 2014 saw discussions regarding scheduling practices of Dynamics & Pseudo Ties Question had been raised if both these schedule types were being utilized correctly in the interconnection, were their any reliability concerns, was there a need to consider a regional criteria or guideline Dynamic Transfer Work Shop

11 Recommendation from workshop back to JGC o Further education on Dynamic Transfers and associated tagging requirements be explored by ISAS.  WECC staff will assist ISAS in acquiring data and developing educational materials. o We do not see the need for a Task Force to be formed at this time.
