Unreliable power supply has made operating a business more challenging than usual in Sub-Saharan Africa. This research aims at comparative analysis of techno-economic feasibility of a sustainable hydro-solar energy system without battery storage, using a case study of Aba business cluster, Nigeria. The analysis aimed towards finding the optimum combination based on a compromise of the resources without battery storage. The result showed that photovoltaic/hydro/ battery was the least cost system with a life cycle cost of $380,075 and Cost of energy 0.13$/Kwh, which is slightly lower than photovoltaic/Hydro system without battery with a life cycle cost of $450,428 and Cost of energy 0.15$/Kwh. However, the configuration without battery storage is considered the best as its devoid of capacity loss due to corrosion and degradation of batteries. The study further demonstrated that the addition of solar photovoltaic generation capacity is more valuable than storage capacity, which increases the competitiveness of solar with overall operational sustainability, especially in a commercial application with adequate demand response to maintain the system operational reliability. The study has introduced a design technique in finding the optimal mix of hydro-solar energy resources without battery storage.
