High Voltage
Utility-grade engineering for critical high voltage infrastructure
When your project involves high voltage infrastructure, you need engineers who understand far more than drawings and calculations. You need a team that understands how HV assets are designed, constructed, commissioned and safely operated in the field.
Power Edge Engineering provides specialist high voltage engineering services across industrial facilities, utilities, renewable energy projects, embedded networks and private power systems throughout Australia.
Utility-grade engineering, from design to energisation
Whether you're upgrading an existing substation, commissioning new switchgear, integrating generation or modifying protection systems, we deliver engineering and HV field services that align with Australian Standards, network requirements and industry best practice.
Our team works comfortably alongside asset owners, electrical contractors, EPCs, commissioning teams and network service providers to deliver projects safely and efficiently.
Our capability includes:
- AS 2067 compliant substation design
- Protection and control system design
- Protection relay settings and coordination studies
- Earthing system design and verification
- Arc flash hazard assessments
- Generator, solar and BESS grid integration
- HV switching procedures and operational documentation
- Factory Acceptance Testing (FAT)
- Site Acceptance Testing (SAT)
- Protection testing and commissioning (using Omicron test kit)
- Energisation planning and commissioning management
- Asset upgrades and brownfield modifications
- Network connection R2 hold-point testing
Every project is developed with a strong focus on safety, maintainability and long-term asset performance.
Our designs are developed in accordance with relevant Australian Standards including:
- AS 2067 High Voltage Installations Exceeding 1 kV AC
- Applicable Network Service Provider requirements
- AEMO and Generator Performance Standard requirements
From protection philosophies through to commissioning documentation, our engineering is developed with practical construction and operational outcomes in mind.
Engineering backed by real commissioning experience
Many engineering firms produce drawings. Few have spent years commissioning generators, synchronising power stations, testing protection schemes and energising live high voltage infrastructure.
Generation & Renewables
Commissioning multi-megawatt generation systems and renewable energy facilities, from synchronisation through to full grid integration.
Industrial Substations
Energising and commissioning complex industrial substations, with practical knowledge of how these systems behave on site.
Protection Systems
Testing and commissioning complex protection schemes, backed by hands-on field experience rather than drawings alone.
This practical knowledge results in engineering that is realistic, constructible and readily commissioned on site. When unexpected site conditions arise, our engineers understand how systems behave because we've worked on them ourselves.
Safe energisation begins with competent people
Our team understands the operational requirements surrounding high voltage access, isolation, switching and energisation.
Switching Operators are ElectraNet Category 2 qualified & nationally accredited to perform switching on private infrastructure.
Every project is different. Power Edge Engineering evaluates each site's energy demand, operating profile and commercial objectives to determine the most effective solution and expected return on investment.
Confidence when the power matters
Power Edge Engineering has built its reputation by supporting critical electrical infrastructure where reliability cannot be compromised.
Our engineers have delivered projects for utilities, industrial processing facilities, renewable energy developments, ports, water authorities, mining operations and major infrastructure owners.
Field Experience
Practical engineering backed by field experience.
Utility-Grade Capability
Utility-grade technical capability across every project.
Protection & Power Systems
Strong understanding of protection and power systems.
Clear Documentation
Clear documentation that simplifies construction and commissioning.
Power Edge Engineering provides the confidence that your high voltage assets are designed correctly, commissioned safely and ready to perform for decades to come.
