CISNEROS RAMIREZ, César A. et al. Preliminary economic and technical evaluation of the production of electricity from solar thermal plants in Cuba. Energética [online]. 2021, vol.42, n.1  Epub 01-Mar-2021. ISSN 1815-5901.

Based on the interest that the Cuban state presents to increase the inclusion of renewable energy sources up to 24% in the country's energy matrix, the idea of ​​carrying out this work, which consists of evaluating the feasibility of the production of electricity from solar thermal plants in Cuba. The technologies of the analyzed thermosolar plants are parabolic cylinder, Fresnel and central tower. The analysis variables that were chosen were power purchase agreement (PPA), internal rate of return, net present value, capacity factor, conversion factor and quantity of water used. For this, were selected three localities belonging to the western, central and eastern region. In addition, were analyzed two types of cooling: by air and evaporative. The results show that the cost of kWh ranges between 20 and 38 cents depending on the type of technology and region of analysis.
