Document Description
The proposed project includes construction and operation of a new 115-kilovolt subtransmission line. The subtransmission line would extend from SCE's existing Valley Substation in the City of Menifee, California, south ~15.4 miles, to just west of SCE's existing Triton Substation in the City of Temecula, California. The proposed project includes two segments; Segment 2 (~3.4 miles) only involves reconducting. The purpose of the proposed project is to provide additional capacity to serve long-term forecasted electrical demand, enhance electrical system reliability, provide greater operational flexibility, and provide safe and reliable electrical service.
