icubed consulting undertook the role of Civil and Structural Designer for the Balance of Plant Works at Dundonnell Wind Farm, delivered by our long-term partner Zenviron. The project, developed by Tilt Renewables, consists of 80 Vestas Wind Turbine Generators, with an individual capacity of 4.2MW. Combined, the project has a total potential power output of 336 MW, which has the capability to power approximately 245,000 residences with renewable energy.
An on-site quarry was developed and utilised in order to capitalise on the high-quality basalt rock in the area. All civil construction was completed using internally sourced material from the quarry, which significantly limited the extent of project related traffic on the local road network.
Fluctuating groundwater depth across the extent of the project site provided challenging conditions for the structural design of the Wind Turbine Generator foundations. icubed provided three separate foundation designs, depending on the specific groundwater conditions measured at each location, in order to optimise the amount of reinforced concrete used during construction.
The Dundonnell Wind Farm project marks the largest single stage wind farm design icubed consulting have delivered to date. With a blade length of 75m, the Wind Turbine Generators have the largest rotors ever installed in Australia.
