The object of this Master thesis is to discuss the economic viability of a low power Solar Thermal Power Plant, using Linear Fresnel Reflectors, in an isolated system installed in Asterousia of Crete. For this purpose, a presentation was conducted of the main solar thermal technologies, their cost analysis, their market, the industry’s outlook worldwide, the related policies and the existing framework in Greece.
A technical study aiming to calculate the solar power of the area according to the meteorological data was commissioned and presented alongside technical equipment data. The energy study that followed developed a simulation model of the annual operation of the station on an hourly basis, in order to calculate its efficiency parameters and energy flows for each months of the year. Subsequently, a financial analysis and evaluation of the investment was conducted based on annual energy simulation results, where key economic indicators were calculated and assessed. This was followed by a Sensitivity Analysis evaluating various scenarios of key input variables, a Break − Even analysis and the calculation of the most important financial ratios.
The thesis concludes with a summary of the study’s conclusions and proposals. The main conclusion of the study is that a solar thermal power station in an isolated system, can be a viable investment, under certain conditions such as the subsidization of its capital costs, an increase in system performance and a significant reduction in equipment costs, as a result of economies of scale and the development of innovations through R&D.
