Designing High Voltage Infrastructure for Private Networks & Industrial Sites
High Voltage Engineering designs, integrates, and optimises power infrastructure for private networks, industrial facilities, and large-scale developments. Unlike utility-managed grid assets, private high-voltage networks require specialised engineering solutions to ensure safe operation, compliance, and efficient power distribution.
We design and upgrade substations, switchboards, and reticulation networks for hospitals, industrial plants, mining sites, and embedded networks. Our expertise also includes seamless grid connection support with authorities like Energy Queensland.
Using advanced load flow analysis, protection system design, and precise equipment selection, we create high-performance networks that ensure stable, reliable, and safe power distribution for critical infrastructure. Whether developing new assets or upgrading existing systems, we deliver solutions customised to industry standards and project needs.
