      abstract = {The development of any Country is estimated from the amount of energy it produces and consumes in relation to its population. The present shortage of electricity supply in Nigeria is attributed to the too much reliance on depletable energy resources in addition to the Youths Militancy in these oil and gas-bearing communities. Nigeria coastline communities have for long suffered from the combined effect of total absence of electricity and environmental degradation. This study focuses on developing a sustainable hybrid power generation system that combines onshore wind and tidal current energy to provide a stable energy supply for Dawes Island. By addressing the challenges of intermittency and unpredictable nature of renewable energy sources, the study integrates wind and tidal energy with a battery energy storage system (BESS) to ensure reliability. Reducing the cost of electricity generation. The objective of this study is to design and evaluate an integrated wind-tidal renewable energy system that can generate electricity efficiently and reliably while reducing fossil-fuel consumption, greenhouse-gas emissions, and dependence on conventional power sources. A simulation of a hybrid wind an tidal energy system can be developed to model how wind and tidal resources are converted into electrical power and combined to supply a common load. The study employed the Hybrid Optimisation Model for Electric Renewable (HOMER) software to perform simulations to ascertain the hybrid systems’ optimal design. Based on Dawes Island’s geographical location, regional climate data, wind speed and tidal current runs obtained from NASA database and the internet were integrated into the model with geographic data from Google Maps. The hybrid system consists of one Atlantis AR 2000, 2 MW, 11KV output voltage tidal turbine with a WES 30 540 KW, 11KV output voltage, Wind Turbine to harvest the energy resources available at Dawes Island. With water runs of more than 10m/s at flood and ebb tides, in addition to a modest average wind speed of 3.1m/s, the result shows a reliable complementarity of the Power generators, for a stable provision of electricity for the community. The study underscores the need for sustainable energy solutions to balance environmental conservation and socio-economic growth of the numerous Island communities. Modelling and simulation using MATLAB-Simulink software are employed to evaluate the system’s performance under variable weather condition. The simulation results demonstrate the system’s reliability and ability to consistently deliver quality power output and meets the load demand. By leveraging the complementary characteristics of wind and tidal energy, the system mitigates the limitations of single-resource dependency, creating a more resilient and adaptable energy infrastructure. Tidal energy provides a stable and predictable base load, while the wind turbine can boost energy production when wind conditions are favourable. The integration of an onshore wind and tidal energy system would be the best option to meet the energy demand of these communities. In addition, it has the potential to ameliorate climate change and substantially reducing CO2 emission. It is envisaged that the implementation of the suggested energy system for Dawes Island would no doubt support the Niger Delta communities whose livelihoods have been negatively affected by the combined effect of oil and gas exploration to attain their needed economic and environmental potentials which is driven by availability of electricity.},
