We conducted the preliminary engineering design for a new electrical substation and its associated switchyard, intended to supply a data center complex in Clarksville, Arkansas, United States. The project aimed to establish the technical foundations necessary for a reliable, scalable electrical infrastructure capable of keeping pace with the complex’s growing energy demand.

Our involvement included the development of conceptual engineering and the technical documentation necessary to support the future execution of the project under an EPCM model, incorporating design, constructability, and planning criteria from the initial stages.

Scope of the project

We develop:

• Preliminary engineering for the substation and the high-voltage switchyard.
• Design of 69 kV and 161 kV electrical configurations with highly reliable schematics.
• Development of general layouts, single-line diagrams, and grounding criteria.
• Preliminary technical specifications for transformers, switches, and major equipment.
• Technical support for early procurement, including tender documentation, bid evaluation, and cost estimates.
• Project coordination and monitoring of geotechnical studies and the engineering schedule.

Impact of the Project

Through this project, we are contributing to the development of the electrical infrastructure that will power a complex of data centers with high energy demands. Our engineering team provided the technical foundation for a reliable and scalable solution, facilitating the planning of the next stages of design and construction and supporting the growth of critical digital infrastructure.
