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”)

Featured Projects

Grays Harbor PUD Integrated Resource Plan

EES Consulting prepared Grays Harbor’s 2020 Integrated Resource Plan. Grays Harbor is required to submit an IRP to the state of Washington every two years that demonstrates how it will meet the electric power needs of its members with a reliable supply of power delivered in the most cost-effective manner. The 2020 IRP was an evaluation of resource alternatives that could be deployed to meet Grays Harbor’s load and meet state of Washington renewable energy requirements under the Energy Independence Act and carbon-free energy requirements under the Clean Energy Transformation Act. Grays Harbor embarked on an IRP to study alternative sources of supply that could best serve its customers’ needs for the period 2021-2040.

Anchorage Municipal Power & Light

EES Consulting has prepared Integrated Resource Plans (IRP) for ML&P since 2002 to assist ML&P with the evaluation of capital spending throughout ML&P, covering transmission and distribution, generation, SCADA systems, use of dual fuels, and other related areas.  To evaluate the alternatives available to ML&P for future generation, the IRP was developed as a tool for examining the economic, engineering and other attributes associated with various options.
