Hydrological Model and GIS-Based Estimation of Hydropower and Solar Energy Potential in Patimban Area, Indonesia

This study aims at mapping and evaluating the hydropower and solar energy potential in the Patimban area, Subang district, West Java Indonesia, within the vicinity of Patimban Deep-Sea Port construction. The hydrological model, the geographic information system (GIS), and climatology data were exploited to assist the estimation of the site-specific hydropower and solar energy potential. The results at hand reveal that the Patimban area exhibit a promising potential to develop both pico and micro hydropower plants for domestic energy supply in the urban area close to the seaport. Meanwhile, the solar energy potentials in merely 12 ha area determined from the sunshine durations in the Patimban area enable to adequately supply the approximated energy demand of the Patimban DeepSea Port operation. The financing scheme for funding this renewable energy power plant is briefly discussed and proposed as an alternative to the limited budget for the Patimban Deep-Sea Port construction. Overall, the hydrological model and GIS demonstrate their applicability in assessing the potential of environmental sources of renewable energy.
