This paper confers with a study and unfold to systematic know how on how to furnishrnEthiopian universities with power using their own abundantly available renewable energyrnresources and to establish a project for the same purpose. In pursuance of that, it wasrnconducted by collecting and analyzing relevant and required data like electrical energyrnconsumption, weather and site of the targeted universities while also renderingrncomprehensive attention to other design standards as well as specifications of machineries.rnThe worst case design is thoroughly regarded herein the design section for it is morernconvincing with respect factor of safety in the event solar radiation falls below the annualrnaverage and when there is a minimum amount of biogas resource. The simulation,rnoptimization and sensitivity analysis of the project is dealt by renewable energy tools ofrnHOMER software.rnFoundation of the hybrid energy generating system is surfaced and actualized by makingrnestimation of solar and biogas resource at a given site. The source data for AAUCNCScrnrevealed that a mean incident solar radiation of 3.66 kWh/m2/day and a potential of aboutrn24 tons of biogas resource per a day can be collected considering safety factor for thernvariation as per day to day and month to month basis. The data collected for this studyrnfurther showed that the electrical energy demand of the site was 104,870 kWh in therndesign year (July 2012) in which a combination of the two systems are going to offset thernnecessity. The assessment conducted revealed that out of the total of 104,870 kWh energyrnneeded close to 81% is furnished by and fulfilled with biogas energy generating systemrnwhile the remaining 19% of it is contributed by PV/T system and yet 0.00492kWh/yrrn(0.00%) is found to be excess which ought to be sold to the national grid .rnPursuant to the financial analysis of HOMER, given to designed HPV/TBS and within anrnoptimum cost of electricity (COE) of 0.263 $/kWh, renewable fraction (RF) of 1 can bernobtained. Generally, if and when the total cost of PV/T modules, the Biogas generatorsrnand the converter are US$ 535,750.00, US$ 50,000.00 and US$ 8,000.00 respectively. Thernsoftware further showed that in the emission analysis 4,172,041kg/yr of CO2, 18,099 kg/yrrnSO2 and 7,935 NO can be removed if this renewable design of the hybrid system is to bernimplanted instead of non renewable equivalent.
