Abstract: Fiji, a group of volcanic islands in the South Pacific, is located between 15°S and 22°S and longitudes 174°E and 177°W, and experiences a variable wind regime in a relatively small area. In this project wind characteristics and resource assessment for the Laucala Bay area in Suva is investigated using Wind Atlas Analysis and Application Program (WAsP). A micro-scale prediction of wind resource assessment for Nabua is carried out using WAsP. These predictions were based on the digitized map, surface roughness, orography and the obstacle groups present at the Nabua site. According to the WAsP report, Nabua is a poor candidate for wind power generation as it has a mean wind speed of 3.30 m/s and a mean power density of 40 W/m2. WAsP also shows that if Whisper 100 turbine is installed at the Nabua site, it would have an Annual Energy Production (AEP) of 227 kWh. To validate WAsP prediction, on-site wind data were analysed and it was found that the mean wind speed was 3.05 m/s and a power density of 36 W/m2. Statistical analysis carried out on these results showed that WAsP had tendency to over-predict wind regime. A resource grid for the greater Suva area was generated using WAsP. It showed that, within the grid there were some potential wind generation sites, one of such sites being Tamavua Heights. WAsP predicts that Tamavua Heights has an annual wind speed of 13.30 m/s, with a power density of 3286 W/m2 and an AEP of 3.38 MWh for Whisper 100 turbines
