Feasibility Studyand Design Of Micro- Hydro-Pv Hybrid System For Off-Grid Rural Electrification Case Study Becho Woreda Mettu District

Abstract

Now a day’s electricity is the most needed facility for human being. Energy is a series problem in non-electrified rural area. So does Agaro Denda. The district is located at the latitude of 6°16'33.36"N and longitude of 35° 40'19.84"E in Illu-Ababore zone in the western parts of Oromia region. The populations found within the village are so far from grid system, due to this reason the task of their electrification through the grid system is very difficult. In the non-electrified village, the population uses kerosene, diesel, biomass and dry cells for lighting, milling machine, cooking, and radio respectively. As a result of this, the need for providing renewable energy resource such as micro hydropower and solar energy in the district becomes an option. In the combination of two renewable energy resources i.e. micro-hydropower and solar energy hybrid. In this study, feasibility of micro-hydropower/PV/battery hybrid electric supply system to the rural area have been analyzed using HOMER software (hybrid optimization model for electrical renewable) as optimization and sensitivity analysis tool. Meteorological data of the village have been calculated from national meteorology agency of Ethiopia, Ministry of water and energy of Ethiopia, different site and NASA. Surface Metrology is used for the estimation of solar energy potential and micro- hydropower energy potential. Electric load for the basic needs of the community, such as, for lighting, radio, television, ‘injera Mittad’, charger, amplifier and flour mills have been estimated. As a result, based on the storage system and the hybrid system i.e. it determines the feasibility of the system due to different village loads and sources combinations. And it estimates the life-cycle cost of the system, which is the total cost of installing and operating the system over all its lifetime. Micro hydropower/pv/battery it found about $0.243/kWh. as levelized cost of energy.
