The potential of concentrated solar power plants technology (CSP) in Togo is evaluated through the simulation of a plant prototype with a capacity of 50 MW in the climate of Dapaong (Togo. The simulated prototype is the Andasol 1 plant in operation in Aldeire Granada (Spain). Such an installation which produces a net electrical energy of 139 348 MWhel at the output of the system in Spain can produce a net electrical energy of 107 525 MWhel in Togo. For this purpose, three types of technologies most used by stakeholders of the domain, namely: Solar tower, Fresnel mirror and Parabolic trough sensors are presented and an analysis of their economic feasibility has been carried out. On the basis of the analyzed solar irradiation data, the solar tower power plant can produce a net electrical energy of 113 915 MWhel, a power plant using Fresnel mirrors can produce a net energy of 121 054 MWhel against 107 525 MWhel for the parabolic trough technology and this for the same solar field surfaces. A techno-economic analysis places the solar power plant based on FRESNEL mirror ahead of other technologies. The technologies used are equipped with storage allowing production even at night when there is no sun. It was therefore found that Togo has an average potential for the production of electricity from the CSPs, especially in the northern region of the country.
