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.  This effort to upgrade existing transmission lines within an existing transmission corridor will provide more capacity for renewable power to be delivered to the power grid.
