Changes Since last year: 1) Westpark sub-area has been re-established due to automatic transfer of Magunden substation for the loss of Kern-Magunden-Witco 115 kV 2) 2017 area load forecast remains about same from 2016 3) 2017 LCR has increased by 92 MW from 2016 mostly due to Kern PP #3 & #4 230/115 kV transformer capacity upgrades and additional load (about 280 MW) triggered by re-definition to account for the 3 new Midway 230 kV binding constraint lines. Since last stakeholder meting: 1) Updated NQC. Your comments and questions are welcome. For written comments, please send to: RegionalTransmission@caiso.com Slide 8
