Abstract: Assessing wind energy potential in low Weibull parameter regions is crucial for optimizing wind farm development. This study evaluates the wind power potential in Tbong Khmum and Svay Rieng provinces, Cambodia, using a hybrid approach that integrates 10 years of MERRA-2 reanalysis data with 2–3 years of observational wind data from local weather stations. The analysis focuses on estimating mean wind speeds at 80 and 100 m above ground level (AGL) and predicting annual energy production (AEP) and capacity factors (CF) using three wind turbine models. The wind shear coefficient was determined to be 0.29 for Tbong Khmum and 0.22 for Svay Rieng. Results indicate that Tbong Khmum exhibits a higher wind energy potential, with an AEP ranging from 6.064 to 7.385 GWh and a CF between 20.44 and 40.00%. In contrast, Svay Rieng demonstrated a lower AEP, ranging from 4.232 to 6.139 GWh, with a CF between 14.21 and 33.37%. These findings suggest that Tbong Khmum is more favorable for wind power generation, although both sites exhibit promising potential for renewable energy development. The study underscores the importance of combining reanalysis and observational data to enhance wind resource assessment in regions with limited historical wind measurements.
