Cost Comparison
• Cost is a sensitive issue, and an important one
• Influencing factors on cost of CSP plants
– Competitive situation of component suppliers (e.g. oligopoly)
– Competitive situation of markets (e.g. generous Spanish CSP-tariffs)
– Risk evaluation (e.g. new technologies, countries, companies’ infrastructure)
– Irradiation influences energy yield and hence LEC
