Wind Energy Analysis for Vadravadra Site in Fiji Islands: A Case Study

Rising fuel costs, increased energy consumption, and growing environmental concerns have led mankind to look for alternate sources of energy apart from conventional fuels. One of the promising renewable energy sources is wind energy. For harnessing wind energy from a wind turbine or wind farm, wind resource assessment (WRA) needs to be carried out. WRA will highlight which site is optimum (in terms of economics and wind characteristics) for wind turbine installation and how much would be the estimated energy output from that particular site. This paper presents the estimate for annual wind energy yield for the Vadravadra site in Gau Island in Fiji. It also presents a method for finding the optimum wind turbine that can be installed at a site and the kind of wind turbine that should be installed at a site, where cyclone may hit the area.
