Substation
Services & Experts

Our substation design experts with combined experience of over 50 years across various voltage levels, including 132kV, 220kV, 380kV, and 500kV. Expertise spans primary and secondary engineering, relaying and protection, system studies, and consultancy for AIS, GIS, and digital protection substations. We cover substation design and engineering, starting from site selection, feasibility to ensure optimal placement. We handle electrical design, including Single Line Diagrams, equipment layout, cable routing, grounding, and lightning protection, alongside structural and civil design for stable foundations.

Our protection and control systems experts focus on relay coordination and switchgear configuration for safe power management. Environmental and safety compliance are prioritized through impact assessments and measures to minimize noise and EMF exposure. We also offer solutions for substation expansion and modernization, with full support for testing, commissioning, and comprehensive handover documentation.

Conceptual Design & Feasibility Studies

  • Site Selection: Identifying optimal locations for substations through in-depth site evaluations and feasibility studies.
  • Layout Planning and Load Forecasting: Developing initial layout plans and forecasting load requirements to meet future demand effectively.
  • Voltage Selection: Determining the appropriate voltage levels to maximize efficiency and reduce losses.

Electrical Design
