In Nigeria, some economically important facilities are not functioning optimally due to lack of/inadequate electricity from the national grid. To solve this problem, these facilities result to using diesel generators which are mostly uneconomical and environmentally unfriendly. Improving comparative economic advantage means that Renewable Energy Sources (RES) with reduced emission and long term cost of energy is a viable alternative. This work describes the potentials of using solar PV/biogas power system to supply the slaughterhouse located in Ado Ekiti, South West Nigeria through an optimal design and techno-economic analysis. With an annual average daily radiation of 4.93 kWh/m2/d, the facility slaughters an average of 25 cows daily to yield a biomass supply of about 1150 kg/day. Simulation results from HOMER software present an optimal PV/biogas generator/battery/converter system that is able to supply the 164 kWh daily load requirement of the facility. The PV system supplied 38% of the annual total electricity production which stood at 76,384 kWh/yr. Cost analysis also indicates that the system has levelized cost of energy of $ 0.236/kWh and a Net Present Cost (NPC) of $ 92,988. 60% of this cost is shared equally between the PV and battery storage system while the biogas generator and digester and converter cost make up 25% and 15% respectively.<
