Abstract
Fiji is located in the South Western part of the Pacific between latitude 18° S and longitude 179° E. In 2018, Fiji has spent approximately FJD 800 million in importing fossil fuel to meet the rising energy demand in the country. In the previous year’s several solar PV and wind resource assessments has been done and results obtained indicated that there is a potential for grid connected electricity generation using recommended resources. This study was carried out in the Nasawana Village (16°55.3 S and 178°47.4 E) to determine the options to use electricity derived from the wind. Wind analysis was carried out using Wind Atlas Analysis and Application Program (WAsP) that predicted the wind speed of 6.96 ms−1 and a power density of 256 Wm−2 at 55 m a.g.l. The annual energy production predicted for a single wind turbine (Vergnet 275 kW) is approximately 631.6 MWh with a capacity factor of 26%. The cost of energy per kWh is estimated as FJD 0.10 with a payback period of 7 years.

Current developments of wind in the pacificFossil fuels cater for around 72.7% (REN21, 2020) of the energy needs globally that have profound impact on climate change
Fiji’s Electricity demand as of 2018 was approximately 1033 GWh of which 43% was generated by diesel generators and 57% by renewable energy resources comprised of hydro, wind and solar (EFL, 2018)
The objective of this research was to find out the potential of wind energy resource of Nasawana Village in Nabouwalu, Vanua Levu and determine its economic viability
Summary
Current developments of wind in the pacificFossil fuels cater for around 72.7% (REN21, 2020) of the energy needs globally that have profound impact on climate change. Fiji’s Electricity demand as of 2018 was approximately 1033 GWh of which 43% was generated by diesel generators (fossil fuel) and 57% by renewable energy resources comprised of hydro, wind and solar (EFL, 2018). This demand is expected to increase substantially in the near future. Most of the rural settlements in Fiji do not have access to grid electricity because of its remoteness and low population density. It shows that Fiji is amongst the highest producer of electricity using renewable resources in the pacific
