Sun power is a potentially inexhaustible source for energy production. The advantage of solar energy is that the fuel is both free and abundant. In the face of global warming, with energy policies calling for wide-scale use of re- newable and sustainable technologies, solar projects are proving increasingly valuable in the reduction of fossil fuel energy use. Cost reduction forecasts implicate that CSP plants could be competitive with fossil fuel power stations in the near future. Solar power technologies since the solar boom of the eighties in USA, solar thermal energy has been a proven technology. The most common type of plant is the parabolic trough collector, but alternative technologies are rapidly coming to the fore, such as linear Fresnel collector plants with flat mirrors and central tower plants with slightly curved mirrors or heliostats. The basic principle is the same for all three plant technologies： mirrors concen- trate the incident solar radiation onto a receiver where it is converted into heat that is used to produce steam to drive a steam turbine. Heat storage systems like molten salt tanks provide for power supply even during unfavorable weather conditions or at night. They significantly increase the number of full-load operation hours with optimal steam turbine efficiency. Turbines for all main CSP technologies with its broad steam turbine portfolio, Siemens of- fers a range of turbines for different types of solar plants and all power outputs. The turbine technology fits all three common concentrated solar power （CSP） concepts. Siemens was the first steam turbine supplier to re-enter the CSP market in the 21 st century, pioneering commercial solutions in the solar field heat transfer fluid cycle steam heat ex- changers Today, Siemens is the world market leader in steam turbines for CSP plants and has more than 20 years of experience with steam turbines for daily cycling. The SST-700 steam turbine in the US King City power plant is a good example of this
