Abstract

Off-grid electrification is the electricity supply without using public electricity and generates electricity. The rural area is far from the urban area, lacking clean water and electricity necessities. The geographic location makes it difficult for rural areas to connect with the grid electrification, and the cost is high if they want to connect to the grid. Thus, this has made the community of rural life an uncomfortable and inconvenient lifestyle. The diesel generator is not used in the off-grid system because the diesel is non-renewable energy and is not eco-friendly. Bahir Dar village, the rural area in Ethiopia, has renewable resources such as solar, wind, and biogas to provide the needed power demand without requiring the national grid is selected. This project assesses the potential and feasibility study on PVWind- Biogas hybrid system with the battery storage as the backup system is done to electrify the Bahir Dar village. In addition, electric load demands for the community are considered. The hybrid system optimized by Homer is cost-effective to give electrification support to the village. The method used to do this project is through a lot of journal research, and then the load estimate is done by observing the daily activities of the villagers. Then, the selected place is simulated in the Homer Software. PV-Wind-Biogas with the battery is the optimization result for the Bahir Dar village with the (NPC) Net Presenting Cost of $78,517, and the Cost of Energy is $0.100.
