Substation Design
Future-Ready, Reliable Power Without Compromise
Looking for a modern and reliable substation design? At Power Structure Solutions (PSS), we specialise in engineering design and documentation for power systems that are safe, efficient, and future-ready. Whether you need a new substation, an upgrade, or technical design coordination support during expansion, our team has the experience to deliver accurate, standards-compliant results. We make engineering simple, innovative, and sustainable.
PSS is an Australian engineering consultancy specialising in the design and documentation of high-voltage substations, high-voltage transmission lines, and renewable energy connections. We support our clients and EPC partners through every stage of the project — from concept development and feasibility studies to detailed design and technical coordination during construction.

Comprehensive Substation Engineering Services
We support your project from concept through to documentation and technical coordination. Our engineers guide you through every stage of your substation project.
Feasibility Studies & Site Assessment
We start by studying the land, local rules, and environment to find the best location and setup for your substation from a design and compliance perspective.
Conceptual & Master Planning
Our team creates clear layouts and diagrams that show how your substation will work and grow in the future.
Detailed Electrical & Structural Design
We design everything from transformers and switchgear to protection systems, buildings, and safety clearances. This includes both traditional and Gas-Insulated Substations (GIS), delivered as full design documentation packages for EPC partners.
Relay, Protection & Control Systems
We set up intelligent protection and control system designs using modern communication tools like IEC 61850 and DNP3, enabling safe and efficient network management.
Auxiliary Systems & Civil Works
We design support systems such as cables, grounding, lighting, fencing, drainage, and control rooms to integrate smoothly with EPC construction teams.
Modernisation & Retrofit Upgrades
Want to make your current substation more powerful or modern?
We help you upgrade or retrofit existing substations through design enhancements that include digital control systems and renewable energy interfaces such as solar or wind.
Construction & Commissioning Support
While PSS does not perform on-site construction or electrical testing, we provide design coordination and documentation support to EPC partners during execution and commissioning to ensure compliance and smooth energisation.
Why Choose PSS for Substation Design?
Because we design smarter, safer, and stronger substations, built to last.
Advanced Engineering Tools & Models
We use the latest design software like ETAP, AutoCAD, PLS-CADD, OpenDSS, and SKM to make sure every design is accurate and reliable.
Standards-Driven Approach
Our designs follow AS/NZS, IEC, and IEEE standards and are developed in accordance with connection requirements from ElectraNet, Powerlink, Transgrid, and other Australian utilities.
Smart Grid & Communication Integration
We prepare your substation for the future by integrating SCADA systems, fibre networks, and digital relays for intelligent, real-time control.
Deep Industry Experience
Our team has worked on projects in urban, regional, and remote locations across Australia. We understand the unique needs of every location.
Sustainable & Cost-Efficient Designs
We design substations that are eco-friendly, space-efficient, and cost-effective, helping you save on long-term operational costs while supporting sustainability.
Our Substation Design Workflow
We follow a clear and proven process to make sure every project is successful.
- Preliminary Assessment & Concept Design
We start with site studies and load forecasts to plan a reliable layout that suits your needs. - Optimised Layout & Design Refinement
Using simulation tools and client feedback, we fine-tune your design for safety, space, and easy access. - Engineering & Detailing
Our engineers create detailed electrical, structural, and civil design drawings and documentation ready for construction by EPC partners. - Communications & Control Integration
We add SCADA, fibre links, and remote monitoring systems for smarter and safer operations. - Quality Assurance & Review
Every design goes through thorough checks and simulations to ensure quality and reliability. - Implementation Support & Commissioning
We provide technical support and design validation assistance during implementation and commissioning phases, ensuring design intent is met.
