The intention of this research is to obtain an ideal suited arrangement of hybrid electricity generation system using various renewable energy sources to meet the village load prerequisite reliably, economically, endlessly, and sustainably. Hybrid system consists of sun energy, wind power, and conventional electric generator. The analysis is done in the year 2017–2018 at Deleta Village in Meta Robi District, Oromia region, Ethiopia for hybrid electrification. The required solar potential values and wind speed statistics were taken from NASA. The data shows that the study site has an average wind speed of 2.9 m/s at 10 m anemometer and solar radiation of \(5.81\;{\text{kWh}}/{\text{m}}^{2} /{\text{day}}\). The cost of associated hybrid components is collected from various springs and the electric load data was estimated for community and public service’s needs. HOMER software was used to perform techno-economic assessment to meet the load requirement using renewable hybrid off-grid configuration. Based on the resources, load, hybrid system, and the component cost input data were considered. The simulation in HOMER gives optimization, sensitivity, and grid comparison results. The optimization result of the simulation demonstrates that the hybrid configuration achieves total NPC of $1,506,689 and COE of 0.360 $/kWh at a renewable fraction of 0.6 as the best optimal hybrid configuration considering economic and environmental point of view. From environmental standpoint of view, the system is characterized with a minimum percentage of carbon dioxide and other GHG emissions of about 195,974 kg/year.
