The rate of access to electricity in Togo is estimated at 45% in 2018 despite the enormous solar potential with approximately 3203.1 hours that the country has. In order to remedy such a situation, the country plans, as part of its energy policy, to build a 30 MWp solar power plant with energy storage in Dapaong in northern Togo. In this article we propose a pre-feasibility study for the construction of the plant by addressing the technical, financial, environmental and social aspects. The construction of such a plant would require the installation of 112,320 solar panels of 275 Wp over an area of approximately 80 Hectares. We consider within the framework of this study, an energy storage duration of 2 h or 68 MWh thanks to the use of Lithium-ion batteries. The installation of this plant should require, according to our study, an investment of 82.4 million USD (50 billion XOF) with a cost of electricity produced by the plant of 0.16 USD/kWh (98.37 XOF/ kWh). This plant should make it possible to avoid an emission of around 30,749.76 tons of CO2 equivalent per year by producing clean electricity of around 42.7 GWh per year.
