Bali, a world-renowned tourist destination, continues to rely heavily on electricity from the Java electricity grid. The supply, transmitted through vulnerable underwater cables, is at constant risk from earthquakes and tsunamis. With less than 5% of its energy generated locally, Bali struggles to meet national renewable targets and achieve energy self-sufficiency. Though solar panels have been introduced, their contribution remains modest. Large-scale options like hydropower or geothermal are limited by Balinese cultural values, which emphasize minimal disruption to natural systems. Meanwhile, South Kalimantan, with its huge rivers and undeveloped land, shares similar potential in realizing clean energy. Both regions are now exploring small-scale hydropower as a viable solution to support local energy demand while respecting sociocultural and ecological contexts. From 2020 to 2023, researchers from ITB and TU Delft have worked together to design regionally appropriate renewable energy strategies. This interdisciplinary collaboration draws insights from the Netherlands advanced energy transition experience to support Indonesia’s sustainable future. The research includes desk studies, stakeholder engagement, and field visits, aiming to shape energy planning that is feasible and culturally sensitive.
