In remote communities, electricity is generally generated by diesel generators, as connection to central distribution networks is difficult or expensive. Diesel generators, which require large quantities of fossil fuels to operate, pose serious environmental, social and even economic problems. They contribute to greenhouse gas emissions and global warming. The solution proposed by the scientific community is the use of renewable energies, available free of charge, with a very low pollution rate compared to diesel generators. In this hybrid renewable energy system to power a telecommunications station in a remote area of central Congo, we carried out a feasibility study using HOMER software. Knowing the site's electrical energy requirements and weather data, the study showed that implementing a hybrid system makes a very good compromise between electrical production and load, operational costs, and the study of sensitivity linked to variations in fuel prices.
