Substation Engineering

EES Consulting provides complete electrical and civil designs of substations, covering gas-insulated substations (GIS) as well as conventional air-insulated substations (AIS). Our experience covers all common switching arrangements (radial bus, main and transfer bus, double bus, ring bus and breaker-and-one-half) for voltages through 230kV.

We perform design of new substations as well as upgrades and equipment change-outs at existing stations. Services include controls and protection system design, site development and drainage design, foundation design, support structure design, bus and equipment layout design, as well as conduit and grounding system design. Our design is performed in close coordination with the project owner to ensure the owner’s requirements and interests are fully reflected in the final design.

EES provides complete design and bid documents and, if requested, construction support services to the owner, such as shop drawing reviews and witnessing factory and field tests through project commissioning. Our experience also covers development of bidding documents for alternative project delivery methods, such as EPC (“Engineer, Procure, Construct”)
