Abstract
In Indonesia, one of the renewable energy sources which is promising to be developed for producing electricity at a certain region is wind energy. However, a suitable area for the wind farm is affected by various factors. Therefore, selecting the best site using a certain procedure is important to maximize the benefits obtained. This research has the focus to identify the optimal location in Jeneponto regency, South Sulawesi province based geographic information system (GIS) for developing wind power plant (WPP). Three step analyses using the scoring approach with 7 parameters in total were applied to determine the best location specifically. The adopted parameters which are considered affect decision in building WPP at particular place include wind potential, elevation, slope, land use type, soil condition, populated area, and distance to roads (access). In the first step analysis using 5 parameters for eleven sub-regencies in Jeneponto, it is obtained that area within Kelara sub-regency is the suitable location. To identify more detail, second step analysis using 5 parameters for 10 villages within Kelara sub-regency shown that there are three villages as candidates for the best location as indicated by the same highest scoring total. Next, final analysis for the three locations using all considered parameters shown in Tolo village is the best site with 127-hectare area. As applied procedure based GIS is capable in determining optimal location, presented results useful to increase more WPP particularly in South Sulawesi to follow electricity demand growth.
