Solar thermal power stations operate in the USA and Spain, and the largest of these is the 354 MW SEGS power plant in the Mojave Desert. (phys.org)
With that amount being applied to the installation of Concentrating Solar Thermal power stations of the trough type, this would build 60 gigawatts of generating capacity by 2020 thereby replacing most of Australia's coal powered infrastucture with indeffinite life solar thermal power.

BrightSource's technology is also being deployed at the 121 MW Ashalim Solar Thermal Power Station, now under construction in Israel and on track to come online by 2018. (brightsourceenergy.com)
