Wind-PV-diesel hybrid power generation system technology is a promising energy option since it provides opportunities for developed and developing countries to harness naturally available, inexhaustible and pollution-less resources. The aim of this study is to assess the techno-economic feasibility of utilizing a hybrid wind-PV-diesel power system to meet the load of Al Hallaniyat Island. Hybrid Optimization Model for Electric Renewables software has been employed to carry out the present study. The simulation results indicate that the cost of generating energy (COE) is $0.222 kWh-1 for a hybrid system composed of a 70kW PV system, 60kW wind turbine and batteries together with a 324.8kW diesel system. Moreover, using the same system but without batteries will increase the COE to $0.225 kWh-1, the fuel consumption, the excess energy and the total operating hours for the diesel generators. The PV-wind hybrid option is techno-economically viable for rural electrification.
