We are the engineer-procure-construct (EPC) partner for upgrades to the Southwest Substation in Anaheim, California. Planned improvements will increase capacity and enhance system reliability while the substation remains in operation.

The City of Anaheim is upgrading the existing Southwest Substation to support future load growth and strengthen electric system reliability. We are providing EPC services for the project, which includes new 69/12-kV power transformers, 12-kV metal-clad switchgear, 12-kV capacitor banks, station service transformers and a new control building equipped with protection, communications, and supervisory control and data acquisition (SCADA) systems.

The project will integrate a combination of owner-furnished and contractor-provided equipment. Our team is responsible for site grading, foundations, structural systems, duct banks, cabling and electrical interconnections. A 15-foot-tall precast concrete perimeter security wall will extend onto adjacent city property to enhance site security and provide additional visual screening.

The project team is planning and implementing phased construction, cutovers and energization sequences to maintain uninterrupted service for Anaheim’s residential and commercial customers. This includes close coordination of outages and commissioning activities as new equipment is integrated with existing 12-kV circuits. Following successful energization of new systems, legacy equipment and facilities are being decommissioned, demolished, recycled or salvaged.

Upon completion, the project will increase substation capacity and operational flexibility while supporting Anaheim’s long-term reliability objectives. Modern metal-clad switchgear and capacitor banks improve power quality and maintainability, and the upgraded site layout enhances safety, resilience and readiness for future expansion.
