Abstract

Purpose – The aim of this paper is to analyze the wind regime at Wainiyaku, Taveuni in Fiji, estimate Annual Energy Production (AEP) using a 275?kW Vergnet wind, and determine its economic viability. Design/methodology/approach – The only grid supply is in the northeast (suburban area) of the island. The main source is diesel generators, which are operated only certain hours per day. The study around Wainiyaku state was essential to determine an alternative continuous source of energy. The wind assessment on the island was based on the data provided by the Department of Energy (Fiji) and WAsP was used to reliably estimate the wind power potential on the island. Findings – The report suggested that Wainiyaku Taveuni is a good site for wind power generation based on mean wind speed at 30?m agl. The software predicted a resource grid for mean wind speed and power density around Wainiyaku. An economic analysis for a prospective wind power generation using Vergnet 275?kW showed a reasonable promise. Research limitations/implications – The conclusion justifies that a longer period (3y) data are necessary for better accuracy. However, one-year data are sufficient to predict annual energy production with reasonable certainty. Originality/value – The paper provides an alternative solution for a continuous supply of electricity for a remote island. It shows the economics of utilizing wind power generator to provide unobstructed supply of electricity. It further explores the saving in foreign exchange for a small Island economy. The analysis of wind regime suggests that an independent power producer may consider investing in a wind farm at Wainiyaku.
