Wind Energy Potential in Bonny Island Coastal Area of Nigeria Using Weibull Method

Abstract

This study presents a detailed assessment of the wind energy potential of Bonny Island, Nigeria using the Weibull method. This study evaluated the wind energy potential of Bonny Island using 7-years historical wind data (2017–2023) and advanced modeling techniques, including Weibull distribution analysis. The findings highlight that the average wind speed on Bonny Island is 4.15 m/s, with a power density averaging 157.9 W/m² with a 50th percentile of 129 W/m². These metrics, though modest compared to global standards, provide a stable resource for energy generation, making Bonny Island a viable candidate for wind power development. Turbulence intensity was found to be moderate, with about 35% of the observed days falling within the range of 0.15 to 0.20, indicating relatively stable turbulence levels over time The statistical analysis of wind speed and power density revealed variability across seasons, with the rainy season demonstrating stronger wind regime and higher power density than the dry season.
