Figure 3: Sunshine in Namibia in kWh per m2 per day 
CSP is a commercially available solar energy technology that uses direct sunlight (technically known as the DNI) and mirrors to create high temperature steam to drive conventional steam turbines with or without storage. A typical CSP power plant as shown on Figure 4 is comprised of the following components; solar field (e.g. the Nevada Solar One as shown on Figure 5), power block, thermal storage (optional), cooling tower and all other components found in any thermal power plant except the heat source. While a number of CSP candidate technologies for utility-scale applications were recently studied, only parabolic troughs and central receiving system (tower technology) are being considered for the initial CSP investments6. In the last decade, several companies have emerged as leaders in the various CSP technologies. With respect to the trough systems, key players include Abengoa Solar (Spain), Acciona (Spain), FPL Energy (USA), Solar Millennium (Germany), Solel (Israel), and SkyFuel (USA). For tower systems, the market players include Spanish company Abengoa Solar, and the US companies, Bright Source Energy, eSolar, and Solar Reserve. Figure 4: Typical CSP plant schematic diagram
