Abstract: The current study evaluates the technical and economic viability of a project for off-grid power generation using renewable resources, by upgrading an existing system of a diesel generator powered by mixtures of Jatropha biofuel with diesel for electricity generation to rural inhabitants in Mozambique. The investment on the current system was 290645.00MZN ($5363) included in a system of extraction and oil degumming of Jatropha curcas L., which was used to charge a set of 23 lead-acid batteries (12V, 50Ah) rented to the population. However, the uptake of this solution by the population was lower than expected (10 batteries rented per day in average). In the current study, it is considered that the power of the energy required daily to load 20 batteries is supplied by additional renewable energy resources, like PV and micro-wind turbines, in order to improve the economic feasibility of the system for the population. The results show that the system upgrade with PV panels, or PV panels and a wind turbine has technical advantages over the current system and lower costs, which suggest that upgrading the current system with renewable energy generation would improve the usability of the system. |
