Evaluating Wind Energy Potential in the Negros Island Region: Regional Analysis and Feasibility Assessment

Abstract

This study evaluated the wind energy potential of selected coastal and inland locations in the Negros Island Region using quantitative analysis of wind speed data. The research aimed to assess wind characteristics by computing the mean wind speed, wind speed range, and wind speed frequency percentage for each selected site. Wind speed values from locations including Tanjay City, Dumaguete City, San Carlos City, Bayawan City, Bacolod City, and Escalante City were analyzed to compare wind behavior across different geographic settings. Results revealed that coastal locations, particularly Bacolod City and Dumaguete City, exhibited higher and more stable mean wind speeds compared to inland and partially sheltered areas. Wind speed variability across all sites was generally low to moderate, indicating relatively consistent wind conditions, while frequency analysis showed recurring wind speeds that suggest predictability is important for energy planning. Although the observed wind speeds may not be sufficient for large-scale wind farm development, the findings indicate that small-scale or community-based wind energy systems are feasible in certain coastal areas. The study highlights the influence of geographic factors such as coastal exposure, terrain, and proximity to open seas on wind behavior and provides baseline information to support future renewable energy planning and research in the Negros Island Region.
