Wind Power Potential Analysis for Sustainable Development in Northern Sumba

This study analyzes the wind characteristics and energy potential at two locations in Indonesia, Haharu and Laepori, on the northern coast of Sumba, over ten years (2011-2020). The data were obtained from NASA’s Langley Research Center (LaRC) POWER Project and processed using windographer software. The analysis covers various aspects such as wind speed, wind direction, Weibull distribution parameters, wind power density (WPD), and the net energy output of a horizontal wind turbine. The results show that both locations have similar wind patterns and performance, with minor differences in certain months and years. Haharu generally has a higher average wind speed, wind power density, and net energy output than Laepori. The dry season (May to August) is the most favorable period for wind energy production at both locations, while November, December, and March are the least favorable. The prevailing wind direction is southeast for both locations. The study employs an 800 kW Enercon E-48/800 kW turbine to evaluate the potential electrical energy output. The results show that Haharu outperforms Laepori’s net mean power output, with Haharu producing 106.8 kW compared to Laepori’s 103.8 kW.
