Substation Engineering

HomeServicesSubstation Engineering

Substation engineering services encompass a range of specialized engineering activities and expertise related to the planning, design, construction, and maintenance of electrical substations. Electrical substations play a critical role in the transmission and distribution of electrical power, converting high-voltage electricity from power generation sources into lower voltages suitable for distribution to homes, businesses, and industries. These services are essential for ensuring the reliable and efficient operation of the electrical grid. Our services in substation engineering include:

  • Feasibility Studies
  • Site Selection and Evaluation
  • Design and Engineering: Developing detailed engineering plans and designs for substations, including electrical, civil, structural, seismic, and protection and control systems.
  • Equipment Specification: Selecting and specifying the various components of substations, including transformers, circuit breakers, switchgear, and control systems.
  • Seismic Qualification: Ensuring that substation equipment meet IEEE 693 requirements based on the seismic hazard map.
  • Project Management: Overseeing all aspects of substation development, including scheduling, budgeting, procurement, and construction management.
  • Grid Integration/Studies: Ensuring that substations seamlessly integrate into the existing electrical grid, including managing voltage levels, fault protection, and grid stability.
  • Substation Commissioning: Testing and commissioning substations to ensure that they operate safely and efficiently before being put into service.
  • Safety Compliance: Ensuring that substations meet safety standards to protect personnel working in or around the facility.

Smart 3D Modelling

For over two decades, BIM has enabled built environment industry professionals to share information in a single, shared project-based set of objects and systems. It helps clients to understand design and engineering choices visually. It allows the creative team to test options on the layout of critical services virtually. And it outputs vital documentation and enables greater collaboration.

At Equagen, we’ve been pushing BIM’s capabilities, finding ways to amplify these effects and realize its potential and value on all our projects and developing automatic creation of content from data that enables us to respond directly to client needs.

  • BIM Execution Planning
  • BIM Implementation: BIM-based design, construction documentation, scheduling, and cost estimating.
  • BIM Coordination: BIM to coordinate building systems and components across all disciplines, including architecture, engineering, and construction.
  • BIM for Facility Management: asset management, space management, and maintenance management.
  • BIM for Sustainability: BIM to optimize building performance, reduce energy consumption, and achieve sustainability goals.
  • BIM for Construction Management: 4D scheduling, construction sequencing, and resource allocation.
  • BIM for Prefabrication and Modular Construction: off-site manufacturing and assembly.


Seismic Qualification

Substation seismic qualification involves ensuring that substations, critical components, and infrastructure can withstand seismic events, thereby maintaining operational integrity and safety during earthquakes. EQUAGEN is the leading consulting firm for the seismic qualification of transmission and distribution equipment by analysis. We have seismically qualified equipment at GIS, AIS, Synchronous Condenser, FSC, STATCOM, and SVC substations per the IEEE 693.

We use following techniques for seismic qualification of substation equipment structures:

  • Static Coefficient Analysis
  • Dynamic Response Spectrum Analysis
  • Time History Analysis
  • Static Pull Testing / Shake Table Testing
  • Provide Peer Review Services of Seismic Qualifications Reports
