4 4 2. Status of Action Items APS/SRP will try to find a way to provide Joint Participant information in some other way than being part of queues.  Ownership information, unless otherwise made public such as though a public filing, belongs to each individual owners: SRP has no right or duty to post such data on the SRP OASIS. Request APS and SRP to explore the possibility of coordinating Stakeholder meetings with Resource meetings.  Ongoing December 16, 2010 APS & SRP 4th Quarter Stakeholder Meeting

10 10 3.a 2011-2020 Study Assumptions/Methodology  Coordinated Base Cases (Seed Cases) NERC Compliance Studies  2013 – APS/SRP 2013 coordinated case  2017 – APS/SRP 2017 coordinated case BTA Studies  2020 – WECC 2020 HS coordinated case  69kV transmission models incorporated  Most up-to-date forecasts for peak summer loads 10 December 16, 2010 APS & SRP 4th Quarter Stakeholder Meeting

11 11 NERC Compliance Studies Cases  2013 & 2017 Summer Peak & Off-peak Cases  2013 & 2017 Off-peak Cases are Low Load (winter conditions) and High Import (shoulder cases with low generation in the Phoenix Metro Area).  Following analysis are conducted:  Thermal analysis  Post-Transient  Transient Stability 3.a 2011-2020 Study Assumptions/Methodology 11 December 16, 2010 APS & SRP 4th Quarter Stakeholder Meeting
