MODELLING

This study models and simulates the wave energy potential along Nigeria’s coastline to evaluate its feasibility as a sustainable power source. With the nation facing persistent energy deficits and heavy dependence on fossil fuels, wave energy offers a clean and renewable alternative. Using real world oceanographic data from the Copernicus Marine Service (ERA5 dataset), key wave parameters significant wave height (Hs) and mean wave period (Te) were extracted and processed in MATLAB. A dynamic heaving point absorber Wave Energy Converter (WEC) model was then developed in Simulink to simulate power generation over a one year period (September 2024–September 2025). The simulation results show that a single 5-meter wide point absorber can generate approximately 13.88 MWh annually, with peak outputs during the summer months when wave activity is highest. The findings confirm that Nigeria’s wave climate, though moderate, is consistent and technically viable for decentralized, off grid energy applications, particularly for coastal communities and small industries. This research provides a quantitative foundation for future investment, policy development, and pilot projects aimed at integrating marine renewable energy into Nigeria’s sustainable energy mix.
