Data from: Wind resource assessment and energy potential of Natadola in Viti Levu, Fiji

This study uses 1.75 years of continuous measured wind data at a height of 50 m AGL to model and assess the wind resource potential at the site of Natadola in Viti Levu, Fiji, utilizing the Wind Atlas Analysis and Application Program (WAsP). WAsP is employed to model and assess the wind resource and for modelling a 10 MW utility-scale windfarm. The findings indicated that the average wind speed and the mean power density at the Natadola measurement site are 6.94 m/s and 328 W/m2 at 50 m AGL, which falls in Wind Power Class 3 and is suitable for the application of utility-scale wind power. High-resolution resource maps reveal that the Natadola site has an average wind speed of 7.11 m/s, with an average power density of 358 W/m2, and a potential annual energy production of 0.786 GWh at a height of 55 m AGL. The wind direction is dominantly easterly. A model 10 MW windfarm using 37 × 275-kW Vergnet wind turbines at the Natadola site generates a net AEP of 30.947 GWh/year, windfarm wake loss of 5.81 %, Turbulence Intensity of 4 %, and a capacity factor of 0.35. Study aligns with SDG 7 and SDG 13.
