More than 170,000 mirrors will gather tremendous amounts of sunlight and focus it on three towers filled with water, raising temperatures to more than 1,000 degrees Fahrenheit and producing steam that spins turbines that generate electricity.

The project sponsor also omits the fact that it has contracted with General Electric to build less - efficient steam turbines that GE itself says are designed for supercritical power plants, not the requisite ultra-supercritical level of efficiency.

The ANU's deputy director of sustainable energy systems, Dr Keith Lovegrove, said solar thermal had the potential to replace Australia's ageing coal - fired power stations with solar - powered steam turbines.

With this water can be heated to between 500ºC and 2000ºC turning the water into steam which can then drive a steam turbine and produce electricity.

Second, heat recovered from these gases, with additional firing, is the source for producing steam that drives a steam turbine.

With the turbine revolution once more gaining steam, developers of wind power projects need to be aware of all of the infrastructure challenges they are likely to face.

Photovoltaic systems use conducting material to convert sunlight directly to electricity and need only nominal amounts of water to wash their solar panels, compared with the traditional steam - turbine solar that uses much larger volumes of water for cooling towers.

Solar energy can be concentrated with mirrors (CSP) to where it can be used in a steam turbine.

Variation across gas plants is less, though still substantial, with the best combined - cycle plants having nearly twice the efficiency (and hence roughly half the damages) of typical steam or centralized turbine plants, and lower damages even than the cleanest coal - fired plants.

He said that the 400 MWth solar field would be coupled to a Siemens fast start 250 MW steam turbine and an Aalborg steam generator design with a once - though header style heat exchanger design, capable of much more rapid thermal transients to easily handle the rapid start and ramping required.
