Concentrating solar power systems use concentrated solar radiation as a high temperature energy source to produce electrical power and drive chemical reactions. These clean energy technologies are appropriate for Sunbelt applications where direct solar radiation is high. The Global Concentrated Solar Power industry Report 2010- 2011 provides the latest information on the thriving Concentrated Solar Power (CSP) industry, including essential cost and performance data on the four main CSP technologies: Parabolic Trough, Power Tower, Fresnel and Dish Stirling. The Highlights of the report: “Currently there are 679 MW of installed CSP capacity worldwide and more than 2000 MW under construction. The USA is the market leader in terms of installed capacity with 63% market share, followed by Spain with 32% of operating capacity. These two markets will continue to be crucial for the development of the industry into the next decade, with Spain accounting for the largest share of projects under construction with almost 89%. In terms of the technology employed, the market is dominated by Parabolic Trough technology, which accounts for 88% of operating plants and 97.5% of projects under construction. The solar field represents the largest share of the cost of any CSP plant. Depending on the technology this cost could vary from around 43% for Tower and Fresnel technology, to almost 60% for Parabolic Trough and Dish Stirling CSP plants. The most significant cost reductions are likely to come about by innovations in solar field design, which could bring down the levelized cost of energy (LCOE) by 15 to 28% depending on the technology. Experience in Spain has shown that the electricity demand curve almost matches the electricity production curve of a CSP plant. Seasonal variations in solar resources have an effect on the number of hours a CSP plant operates, reducing operating time by almost two hours in winter. This problem can be mitigated by using thermal storage technologies, which would allow CSP to generate electricity during cloudy periods and through the night.” Dr.A.Jagadeesh Nellore(AP),India An emerging area of importance is Concentrating Solar Power Systems.
