The CSIRO's 30-metre-high solar tower is surrounded by 450 custom designed heliostats that concentrate the sun's rays to a central tower receiver. In contrast to solar photovoltaic panels, which convert the sun's rays into electricity, the process generates temperatures of up to 1500 degrees Celsius, which can be used to drive a turbine for producing electricity.

Unlike most concentrated solar thermal power stations, the facility does not require the use of water. It will initially be used to develop and test a 200kW solar air turbine, which generates electricity by compressing and heating air. The turbine also does not require water for cooling, making it suitable for remote areas or where water supply may be an issue. In times of intermittent solar coverage, the turbine can also be driven using natural gas.
