Prioritization decision for renewable energy development using analytic hierarchy process and geographic information system

The purpose of this research is to identify and to rank the prioritization of renewable energy potential development site using Analytical Hierarchy Process (AHP) and Geographical Information System (GIS) for 30 provinces in Indonesia. This study identifies the energy alternative that focusing on solar, wind and geothermal based on previous work by authors. The AHP model is built to identify the weight of criteria for two hierarchies. The weight has been used as input for spatial analysis in GIS method. The resources map is generated by overlaying solar irradiation map, wind speed map and geothermal potential map with spatial analysis tool in GIS environment. The result shows that geothermal is the best criteria, followed by solar and wind alternatives with weight value of 0.72, 0.22, 0.06 respectively. Resource map generated identifies the highly, moderate and low suitability site to rank the priority decision of renewable energy development for Indonesia. The proposed methodology is useful to identify the renewable energy resources site for development priority. The method can be used to achieve the similar objectives for other country.
