West of Devers Upgrade Project
Delivering Renewable Energy for Southern California
We are 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 help in this effort by upgrading existing transmission lines within an existing transmission corridor to provide more capacity for renewable power to be delivered to the power grid.
- Riverside County: Banning, Beaumont, Calimesa, and unincorporated areas
- San Bernardino County: Colton, Grand Terrace, Loma Linda, Redlands, and unincorporated areas
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 (Redlands), Vista Substation (in Grand Terrace), and San Bernardino Substation.
