5. Requested Relief in Petition for Modification of D.07-03-045
The Petition for Modification of D.07-03-045 (`045 Petition) sets forth two distinct requests for relief. First, the `045 Petition requests: (a) an adjustment to the Commission's determinations of the maximum cost for Segments 2 and 3; and (b) a consolidated budget for the entire approved ATP.7 This set of issues will be discussed in further detail in Section 6 below.
Second, the `045 Petition requests minor modification to the route of Segment 3 to accommodate requests from wind resource developers whose project details were not known at the time that the approved alignment was developed, and for additional engineering design reasons.8 These modifications are within the study area boundaries previously studied, and therefore these modifications do not require additional environmental studies.9
More specifically, the modifications are:
· The single-circuit line leaving Substation 2 from approximately mile S3-0 to S3-2.3; the new route deviates from the proposed route by up to approximately 1,000 feet.
· The single-circuit 220 kV line from approximately mile S3-3.9 to mile S3-7.2; the new route deviates from the proposed route by up to approximately 1,000 feet.
· Substation One: Rotate 90 degrees to facilitate the connection of 500 kV and 220 kV lines.
· The single-circuit 500 kV line from approximately mile S3-10 to mile S3-13.5; the new route deviates from the proposed route by up to approximately 1.5 miles. This change accommodates a request from Oak Creek Energy to avoid interfering with wind turbine locations.
· The single-circuit 500 kV line from approximately mile S3-23 to mile S3-26; the new route deviates from the proposed route by approximately 100 feet.
· The single-circuit 500 kV line from approximately mile S3-33.4 to mile S3-33.8; the new route deviates from the proposed route by approximately 100 feet.
· Changes to several structures and structure heights for Segments 3A and 3B based on near-final engineering designs.10
The ALJ and Staff have reviewed SCE's contentions and have determined that they are supported by the record and the `045 Petition pleadings. Therefore, we find that these modifications are reasonable and are required either to provide more efficient access to renewable energy resources or to address engineering concerns.
