Madagascar is well endowed with energy resources, particularly renewable energies.
These include watercourses for hydropower, solar irradiation for photovoltaic
solar energy, wind for wind power, as well as exploitable surfaces for
bioenergy, although these are currently little exploited. What’s more, the electricity
distribution network covers only a small part of the national territory,
which excludes most rural areas. As a result, the population continues to consume
fossil fuels, while gradually turning to solar energy (autonomous installation).
Rural electrification should be totally oriented towards renewable energies,
making the most of hydroelectric sites, solar energy, wind power and
biomass, so that production costs are low, enabling us to offer a tariff adapted
to subscribers’ purchasing power and promote production activities. The aim
of this project is to carry out a technical and economic pre-feasibility study of
a micro-hydropower plant and a photovoltaic system to supply the village of
Mandraka. Initially, field surveys were carried out to establish the consumption
profile and estimate household energy expenditure. Next, a sizing, financial
pre-analysis and system simulation were carried out to assess the economic
interest of the installation. The results of the pre-feasibility study gave
a power of 24.64 kW for the micro-hydro plant and 1.58 kW for the solar photovoltaic
system, which we oversized to 1.76 kW to compensate for unforeseen
circumstances. Finally, a technical-economic study enabled us to obtain a positive
NPV for a minimum cost of 1040 Ar, thus concluding that the project is
feasible. The results of this study show that most households in this village can
afford the cost of electricity consumption
