1 NORTH GILA IMPERIAL VALLEY #2 500 kv TRANSMISSION PROJECT (NG-IV#2 Prject) Prject Overview May 18, 2018

2 PROJECT STATUS AND OVERVIEW Develpment Team ITC Grid Develpment, LLC and Suthwest Transmissin Partners, LLC Single circuit cnfiguratin planned fr initial prject, with lp int the IID Highline substatin t establish a 500/230kV and a reliable utlet fr IID t exprt up t 1250MW f renewables as a new delivery pint Increase reliability f Path 42 and Path 46 under emergency cnditins (lss f existing SWPL) A segment f the lng-term plan develped frm the Imperial Valley Study Grup (CEC spnsred analysis) Ultimate permitting is still anticipated t include up t a duble circuit (e.g. 500/230kV same structure) Submitted as a Interreginal Transmissin Prject t WestCnnect and CAISO, March 2018 Open Huses held Late March 2018 in Yuma and El Centr (Prject Spnsred) EIS/EIR will be initiated in Q3 2018, permitting will include the ptin fr duble circuit Additinal Rute Optins Develped in respnse t agency input Develper is NGIV2, LLC Anticipated In-Service Date Q NG-IV#2 500kV Transmissin Prject

7 NG-IV#2 PROJECT NEED & BENEFIT Ppulatin grwth and increasing energy demands in the Suthwest require additinal transmissin grid capacity. NG IV#2 Transmissin Line will: Prvide additinal imprt/exprt access frm generatin resurce znes where transmissin access currently is limited Reliable utlet fr exprt up t 1,250 MW f renewables Increase transmissin diversity, reliability and efficiency f the reginal grid, particularly thse prpsing t intercnnect t the IID system Resiliency fr lss f the existing Nrth Gila Imperial Valley line Enable mre energy develpers t tap int the reginal grid Prvide supprt t greenhuse gas (GHG) reductin targets 7 NG-IV#2 500kV Transmissin Prject
