Project Header_SCE Substations

Barnard worked to maintain, upgrade, and construct several substations that bring power to the greater Los Angeles area.

Barnard has been in a partnership with Southern California Edison (SCE) since 2019 to perform regular construction upgrades and maintenance throughout several of their substations. Across thirteen different projects in the Los Angeles area, Barnard installed new 220kV transformer bank positions with an existing energized substation; installed new circuit breakers, disconnects, protection and controls; and demolished multiple 220kV substations. Additionally, associated scopes of work included site work, as well as foundation, structural support steel, primary conductor, conduit, grounding, secondary wiring and protection, controls, and communications upgrades within each respective project.
