SCE proposes to construct the Antelope Transmission Project in three sequential segments. SCE’s construction efforts will coincide with the development of privately-owned wind farms that will ultimately produce the electricity that the project is intended to deliver. These wind farms are in varying stages of planning and construction. The first wind farm is expected to be completed by 2007.

The three segments are:

Antelope to Pardee (Segment 1)
Segment 1 would include the construction of a new 25.6-mile, 500 kilovolt (kV) transmission line to connect SCE’s existing Antelope Substation, located in Lancaster, with SCE’s existing Pardee Substation, located in Santa Clarita. Initially, this transmission line would be energized at 220 kV.

SCE would need to modify both the Antelope and Pardee substations to connect the new transmission line, and would need to acquire approximately 70 acres of land adjacent to the Antelope Substation.

Antelope to Vincent (Segment 2)
Segment 2 would consist of 21.5 miles of new 500 kV and 220 kV transmission line connecting SCE’s existing Antelope Substation in Lancaster with Vincent Substation, an existing SCE facility located near Acton. This segment of the project would include the relocation of 4.5 miles of double-circuit 66 kV subtransmission line between Antelope and Vincent substations.

Antelope to Tehachapi (Segment 3)
Segment 3 has four components:

Two new substations
1)  Substation 1 would be located near Mojave
2)  Substation 2 would be located near Monolith
3)  A new 25.6-mile, 500 kV transmission line (initially energized at 220 kV) connecting SCE’s existing Antelope Substation with the proposed Substation 1 4)  A new 9.6-mile, 220 kV transmission line from the proposed Substation One with Substation Two
