Assessing Solar and Wind Energy Technical Potential Using GIS Approach: A Case Study in Sumba Island, Indonesia


Sumba Island is characterized by low population density and inadequate public infrastructure which result in low economic activity and poverty. Nevertheless, abundant yet untapped renewable energy potentials are available across the island. Sumba Iconic Island program has been developed to create a role model for a remote island with 100% renewable energy supply. This study aims to assess the estimated technical potential from PV and wind energy to provide technical knowledge to encourage investor to participate in achieving Sumba Iconic Island goals. We used GIS approaches to estimate available area by setting several criteria based on resource availability and topographic and land-use conformances. Technical potentials were then estimated based on available areas, renewable energy resource and also technological limitations. The results showed that the study area has notable potential of PV at 7755 GWh / year and fair potential of wind at 67.84 GWh / year. Available area for PV are mostly found in Northern parts of study area, such as Kotak Kawau, Matawai Maringu and Matawai Maringa which have plane topographic profiles. On the other hand, high wind speed sites only exist in Kamanggih, Lai Mbonga and Kambata Bundung villages. Considering the sparse settlement distribution and spatial characteristics of renewable energy, distributed system which uses PV or wind turbine is proposed to electrify scattered rural communities with regards to locally available renewable energy resource.
