Resumen:
This study assesses the feasibility of installing concentrated solar power plants in subtropical South America, particularly in Uruguay, by numerical simulations. Parabolic Trough and Solar Power Tower technologies are examined. A comprehensive literature analysis is conducted in order to evaluate initial investment, operation, and maintenance costs. Simulation models are validated in order to ensure results accuracy. The study is focused on the optimization of solar fields and storage sizes for five locations. The target set is to minimize the Levelized
Cost of Energy. In addition, energy losses and efficiencies are compared between Parabolic Trough and Solar Power Tower technologies. Salto region in Uruguay is identified as the most suitable location for Concentrated Solar Power projects. Optimized plants yield solar multiples of 3 or higher for Solar Power Tower and around 4 for Parabolic Trough, with storage sizes ranging from 12 to 15 hours, depending on the location. In Salto, the Levelized Cost of Energy ranges from 148 to 175 USD/MWh for 110 MW Solar Power Tower and from
169 to 220 USD/MWh for 55 MW Parabolic Trough plants, considering different investment cost scenarios. Levelized Cost of Energy is comparable for other locations, with a slight increase of approximately 10% for the least favorable location, Rocha. This work shows that while not yet competitive with photovoltaic or wind technologies, concentrated solar power plants show promise against fossil-fueled power plants and are expected to decrease further in cost.
