The main advantage of CSP as mentioned by Robert Palgrave is that its heat can be stored to enable electricity generation to continue at night and on cloudy days.

A report from the German Aerospace Centre shows that CSP electricity would be one of several renewable sources of energy and could become one of Europe's cheapest sources of electricity. There are also other potential benefits, such as sea water desalination using CSP plant waste heat, for people in countries with sunny climates.
