AB  - This study focuses on determining the optimal size of each component of a hybrid energy system
to meet the energy demand of Itele community in Nigeria at minimum Net Present Cost (NPC). The hybrid
energy system consists of a solar photovoltaic, wind turbine and battery energy storage. HOMER was used
as the optimization tool. In this research, the feasibility and optimal sizing of two different hybrid configurations
were carried out. A standalone and an unreliable grid connected configuration was investigated and optimally
sized. Also, a comparative study on the environmental effect was carried out. The results show that the
unreliable grid connected mode had a NPC of $22.7 million while the standalone system had an NPC
of $29.9 million. But based on environmental impact and emissions, the standalone system offered the cleanest
system with zero carbon dioxide and sulfur oxide emission. While the unreliable grid connected system offered
emission with 394.934 kg/year of carbon dioxide, 742 kg/year of nitrogen oxide and 1517 kg/year of sulfur oxides.
