Southern California Edison Company (SCE) proposes to construct the Auld-Moraga No. 2 115 kV Subtransmission Line Project (Project) within existing SCE easements and along public streets in the cities of Temecula and Murrieta, and unincorporated areas of Riverside County to address system reliability overload conditions. The Project consists of the replacement of an existing single-circuit 115 kilovolt (kV) subtransmission line with a double-circuit 115 kV line.
The new double-circuit line will be constructed on wood and steel poles. Of the approximately 228 poles required for this Project, 122 will be wood and 106 will be steel. The typical height for the new poles will be approximately 70 feet tall. The conductor on the existing single circuit 115 kV line will be transferred from the existing poles to one side of the new double-circuit poles. The new Auld-Moraga No. 2 115 kV line will be strung with 954 Stranded Aluminum Conductor (SAC) and will be placed on the vacant side of the new double-circuit poles. The project will be 8.7 miles long and will connect with existing Auld Substation in Murrieta with the existing Moraga Substation in Temecula. The new double-circuit 115 kV line will begin at Auld Substation, located at Liberty Road and Clinton Keith Road. The line will continue east to Briggs Road, then south across Winchester Road (State Highway 79) to Benton Road. The new 115 kV line will continue east on Benton Road to Leon Road at which point it will proceed south across Murrieta Hot Springs Road, Nicholas Road, and Rancho California Road, before continuing west across Margarita Road to Southern Cross Road at Agena Street and then west to Moraga substation
Pursuant to Commission GO 131-D, Section III.B.1, the Project meets the specific conditions which exempt the Project from the Commission's requirement to file for an application requesting authority to construct. This project qualifies for the following exemption:
"g. power line facilities or substations to be located in an existing franchise, road-widening setback easement, or public utility easement; or in a utility corridor designated, precisely mapped and officially adopted pursuant to law by federal, state, or local agencies for which a final Negative Declaration or EIR finds no significant unavoidable environmental impacts."
This advice filing will not increase any rate or charge, cause the withdrawal of service, or conflict with any other rate schedule or rule.
