Wellspring (Toyota North America) 161/13 kV Substation

Atwell & Gent provided full planning, design, procurement, and construction administration services required to provide electrical service to the new Toyota manufacturing plant in Blue Springs, Mississippi. Design services for this project included foundations, power and control raceways, station grounding, station house, physical layout (section and elevation drawings), and electrical and controls layout and connections (single line, three line, schematic wiring, and point-to-point wiring drawings). Our firm was responsible for procurement of major equipment (circuit breakers, power transformers, relaying, and SCADA systems), review of vendor submittals and drawings as well as the incorporation of the completed vendor drawings into the final construction package. Atwell & Gent was responsible for construction administration of the project, including project coordination and scheduling, field inspections, and substation acceptance testing.

Project Details:
