PENA PUPO, Leonardo; HIDALGO GONZALEZ, Ramón; GUTIERREZ URDANETA, Luis  and  DOMINGUEZ ABREU, Hugo. Integration Proposal of a Solar Thermal Power Plant to the Cuban National Electric System. RTQ [online]. 2018, vol.38, n.3, pp. 551-561. ISSN 2224-6185.

This article is about a technical and economic feasibility study evaluation on the possible integration of a solar thermal energy accumulation power plant with molten salts to the Cuban Electric System. The technical-economic evaluation of a 50 MW project in Cuba shows the current and future feasibility in spite of the high investment costs that it supposes. The paper is distributed in the following way, in the antecedents we state the origin and evolution of this technology, current state of the art of this technology; a world scale installed capacity and its development is described too. After that the operation principle of a solar thermal plant by the Andasol 1 type are shown and the operation possibility is evaluated in Cuba, subsequently the technical requirements are evaluated for the operation of these power stations, the high development areas are presented and was selected the better technical conditions area in which its energy yield is evaluated. At the same time, it has been presented the main advantages and disadvantages too. Finally, it is evaluated economically the interconnection of this solar thermal power plant with the premises approved by the “Unión Eléctrica” for renewable projects under the current conditions besides a forecast toward the 2025.

Keywords : Solar thermal power plants; energy storage; molten salts; direct normal irradiation.
