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
