Turbine components are generally transported by ship to a nearby port and then transported the remainder of the journey by road. Using today’s technology, turbine blades are up to 75m long and hubs are 150m high.

Each turbine foundation is excavated and filled with approximately 100 tonnes of reinforcing steel and 600-800 cubic meters of concrete. The turbines are connected by roads and access tracks, with underground electrical cables running between the turbines to a substation, which connects the wind farm to the electricity network. The cranes used to lift and install the blades, hubs and nacelles are some of the biggest cranes in Australia, lifting components to heights of over 150m.

When operational, the footprint of a turbine includes the foundation, access roads and crane pads and takes up approximately 2 hectares per turbine.

Modern turbines are up to 6m across at the base and big enough to include an elevator to carry service technicians up to the nacelle.

At full speed, a wind turbine can do a full turn every 4 seconds. The tip of the turbine can move at speeds of over 300km/hr.
