Electric Power Substations

Halff provides comprehensive substation design and engineering services tailored to meet the evolving needs of today’s electric power systems. Our multidisciplinary team of civil, structural, mechanical and electrical engineers brings a deep understanding of power system operations, protection strategies and constructability requirements to deliver facilities that perform reliably under real-world conditions.

From concept through construction, we offer complete substation site development services to ensure a buildable, efficient and maintainable location for each station. We support both greenfield substation builds and brownfield expansions at aging or space-constrained sites. Our capabilities also include foundation design for all structural components, electric transmission tie-in design, and the integration of client-specific standards to promote consistency, ease of operation and streamlined maintenance across the entire system.

Our substation and switchyard services include:

• • Site Selection Assessment and Due Diligence
  • Floodplain Analysis
  • Civil Site Development – Grading and Drainage
  • Permitting and Zoning
  • Structural and Foundation Design
  • Lidar scanning to BIM modeling
  • Subsurface Utility Engineering (SUE) and high-accuracy surveying

➔ Safety is our priority.  Safety is a fundamental element in every Halff substation design. We prioritize the protection of personnel, equipment and the public by incorporating best practices, protective clearances and robust safety protocols. Our designs also balance system resilience, safety, reliability, regulatory compliance and future scalability across rural, urban and industrial settings.

➔ We work together as one.  Our team takes a collaborative, client-focused approach to every project, ensuring each substation aligns with operational goals, system standards and regulatory requirements. With a commitment to quality, safety and innovation, Halff delivers high-performance substation solutions that support long-term grid reliability and resiliency.
