Identification of Tidal Energy Resources using Satellite Altimetry Data for Indonesian Seas

FES 2014 tidal satellite altimetry data has been used to know the distribution of regions in Indonesia that have the potential to develop tidal energy. Based on the value of tidal range obtained in each region, calculation estimates the amount of energy that can be produced. Calculation of tidal energy potential has been done using tidal barrage tool design. Based on this research, Southwest of Papua Island has the highest tidal range in Indonesia of more than 5 meters, while west of Sumatera Island (in the north) and southwest of Kalimantan Island have the lowest tidal range less of than 1 meter. Based on our analysis, Bagan Siapi-api (near Halang Island), Bagan Siapi-api (near Rupat Island), North Tembilahan, South Tembilahan, Gulf of Bintuni, South East of Papua (near Arafura Sea) and South of Papua (near Arafura Sea) are the potential locations for development of tidal energy with tidal barrage device. The prediction of electrical power that can be harnessed ranged from 60.45 MW to 3719.13 MW. The highest power that can be obtained is in the area of Gulf of Bintuni and the lowest power is in the area of Bagan Siapi-api (near Halang Island). Southwest of Papua and Northeast of Sumatera are the most reliable regions to develop tidal energy.
