How we work

The work that matters.

High-voltage design, transmission tower design, 500 kV, grid connection and power system studies.

High-voltage design

Substations, plant and secondary systems for the high-voltage grid.

Transmission tower design

Tower, foundation and line design for the corridors that carry the power.

500 kV

The backbone voltage. HumeLink and the other 500 kV work sit here.

Grid connection

NEM and WEM applications, GPS registration, SIPS, and the studies that get generation and storage onto the network.

Power system studies

Dynamic and steady-state. System strength, fault levels, stability and GPS models.
