Valley South Subtransmission Project

Project map

The Valley South Subtransmission Project is our proposal to upgrade the region’s existing electrical infrastructure and improve its overall electrical reliability.

This project will serve the cities of Menifee, Murrieta, Temecula, Wildomar and portions of unincorporated Riverside County, including French Valley, Murrieta Hot Springs, and Winchester.

This project includes the following:

  • The proposed project will be approximately 15 miles in length
  • Construction of a new 115 kilovolt (kV) subtransmission line from our existing Valley Substation in Menifee and ending east of our existing Auld Substation in Murrieta
  • Reconducter (install new conductor wires) on approximately 3.4 miles of an existing 115 kV line from east of our existing Auld Substation in Murrieta to west of our existing Triton Substation in Temecula
  • Install communication equipment at area substations to support the proposed Valley South Subtransmission Project
  • Equipment modifications at Valley Substation

Project is online and operational as of early 2021.
