Delivering Renewable Energy for Southern CaliforniaSouthern California Edison (SCE) is committed to upgrading the region’s power grid in order to help meet California’s renewable-power goals. Our West of Devers Upgrade Project will upgrade existing transmission lines within a corridor to provide more capacity for renewable power to be delivered to the power grid.

West of Devers Upgrade Project OverviewExisting facilities in the transmission corridor west of SCE’s Devers Substation (near Palm Springs, California) are at full capacity. The West of Devers Upgrade Project will provide the additional capacity necessary to bring renewable and conventional generation being developed in desert areas around Blythe and Desert Center, California. These significant upgrades will enhance electric reliability for all customers and help to make the power grid greener for California.

The Project will consist of removing and replacing approximately 48 corridor miles of existing 220 kV transmission lines with new double-circuit 220 kV transmission lines, between the existing Devers Substation (near Palm Springs), El Casco Substation (Calimesa), Vista Substation (in Grand Terrace), and San Bernardino Substation.

In addition, the Project includes relocation of approximately 4 miles of 66kV and 12 kV lines within the cities of Redlands and Loma Linda.

Project Timeline First Quarter 2018: Construction will begin.

Fourth Quarter 2021: Projected In Service Date.

The Approval ProcessSCE submitted a Certificate for Public Convenience and Necessity (CPCN) application for the Project to the California Public Utilities Commission (CPUC) on October 25, 2013 (Application A.13-10-020). The Proposed Project has been reviewed under both the California Environmental Quality Act (CEQA) and the National Environmental Policy Act (NEPA). The CPUC approved the Project in

Decision D.16-08-017 on August 18, 2016. The U.S. Bureau of Land Management issued the Record of Decision approving the Project on December 27, 2016.
