摘要：many nations are embarking on introduction of clean/ renewable energy for displacement of oilproducedenergy. Moreover, hybrid power generation system technology is an emerging energy option since itpromises great deal of challenges and opportunities for developed and developing countries. Ethiopia is one ofdeveloping countries, which has an area of 1,127,127 sq km, and more than 80% of its population resides in rural areaswithout access to electricity. This research paper focuses on feasibility study, design and modeling of a hybrid electricpower generation system using solar/biogas energy resource for area around Tefribirhan village in Oromia regionalstate.The work was begun by investigating solar, biomass energy potentials of the specified site, compiling data fromdifferent sources and analyzing it using HOMER software. The solar energy potential has been given in the form ofsolar radiation plots and calculated using regression coefficients specific to the sites based on the sunshine durationdata. According to the results obtained through the analysis, the site has abundant solar energy potential (5.21 -6.42kWh/m2/day) and, 10 kW biomass generators are considered to find out the most cost effective system. The mainreason of using to fulfill the energy demand in peak hour both for winter and summer season and also meet the terms ofbackup requirements.As biomass resource is available in prosperity, fuel cost is considered zero. The main cost isconsidered for biogas generation procedure and biogas power generator and only cow dung is considered for the biogasproduction.Based on the promising findings of these two energy resource potentials, solar/biogas design of a standalone hybridenergy supply system has proceeded. The hybrid standalone supply system is intended to supply electricity to modelcommunity of 100 households which have lighting, water pumping, a radio receiver, medical equipment for a healthclinic and school with total consumption of 88.02 kWh/day.
