Specifically, the 4 Project will consist of two (2) distinct portions, a northern portion and a southern portion. The 5 northern portion of the Project will connect three (3) existing 138 kV transmission lines into and 6 out of the planned Sonoran Substation. The lines will be supported by three (3) double circuit 7 138 kV transmission structures within a common corridor. The southern portion will connect the 8 planned Sonoran Substation to the planned Cisne Switchyard via a single 138 kV transmission 9 line. Structures for this line will be designed as double circuit capable structures, but this 10 Application requests approval for construction of one (1) 138 kV circuit for this portion of the l l Project. The Cisne Switchyard is a point of interconnection for the planned Wilmot Energy 12 Center ("WEC") to the TEP 138 kV transmission system. 13 The Company proposed two alterative routes for both the norther and the southern 14 portions of the Project. In addition, TEP proposed the Cisne Switchyard as part of the Project. 15 The routes were designated as Northern l and Northern 2 Preferred for the norther portion, and 16 Southern l Preferred and Southern 2 for the southern portion. As a result of its deliberations, the 17 Committee approved Northern 2 Preferred and Southern l Preferred as well as the Cisne 18 Switchyard.
