The Schrader Overhead Transition Corridor would consist of two 230 kV transmission lines to the Schrader Substation through overhead and underground interconnection options that include converting the existing single circuit Corbell to Schrader 230 kV alignment inside the Schrader Overhead Transition Corridor to a new double circuit alignment. Schrader Overhead Transition Corridor: Two new overhead single-circuit 230 kV transmission lines would exit Schrader Substation; one along the south side (southern alignment) of the station and one along the north side (northern alignment). Constraints on the underground routing between Schrader Substation and Chandler Heights Road may require the proposed circuits to exit Schrader to the west or the east within the alignments described below: Southern Alignment – The 230 kV circuit (Circuit One) along the southern alignment would generally be located underground. Whether the circuit is exiting to the west or the east, SRP would place up to three overhead structures within the Schrader Overhead Transition Corridor to make the overhead 230 kV connection in the substation bay and transition to the underground line outside of the corridor. Northern Alignment – The 230 kV circuit along the northern alignment (Circuit Two) would exit the Schrader Substation to the west using the existing Corbell to Schrader 230 kV transmission line alignment approved in Decision No. 59791 as modified by Decision No. 60099 (Corbell to Schrader alignment). At the point where Circuit Two joins the Corbell to Schrader alignment, the two lines would be constructed as above ground, double-circuit 230 kV transmission lines on monopole structures. The new double-circuit 230 kV line would continue along the existing ROW for the Corbell to Schrader alignment within the Schrader Overhead Transition Corridor. The approval to co-locate Circuit Two with the Corbell to Schrader alignment as requested in this Application would amend Decision No. 59791 and Decision No. 60099 to authorize the reconstruction of the Corbell to Schrader alignment within the existing ROW as a double-circuit 230 kV transmission line inside the Schrader Overhead Transition Corridor. SRP would place additional overhead structures within the Schrader Overhead Transition Corridor to transition between the Corbell to Schrader alignment, the overhead 230 kV connection within the substation, and the underground transmission line segment. If the circuit exits Schrader Substation to the east within the northern alignment, SRP would place up to three overhead structures within the substation to make the overhead 230 kV connection in the substation bay and transition to the underground transmission line outside of the corridor, but would not use the Corbell to Schrader transmission alignment.
