Markets - Power Delivery - SubstationsThe reliability of any power delivery system depends on the integrity of its substations. Our engineers have experience with “greenfield” designs as well as upgrades and retrofits to previously developed sites. This experience allows us to overcome the challenges of substation engineering. Our designs are based on the latest industry codes and operational experience. Sega’s substation services include the following: specifications and drawings for site development and permitting, foundations, civil/structural design, electrical design, integration of electrical equipment and related components, grounding, oil containment, and system protection and controls.

Substation Design Services

An integral part of substation, transmission and distribution line design is the civil and structure design component. Our civil/structural engineers are well versed and equipped to support these areas as the project requires.
