Abstract
Ocean Thermal Energy Conversion (OTEC) is a clean marine renewable energy using temperature difference between the sea surface and the deep ocean to rotate a generator to produce electrical energy. As Indonesia is an equatorial country located at latitudes less than 20 degrees covered by 77 % ocean, thousand islands, strain and many difference of topography, OTEC is very compatible build in Indonesian. This paper discussed the potential areas of OTEC to be applied in Indonesia. The paper proposed six regions that very high application of OTEC. They are West Sumatera, North Sulawesi, North and South Maluku and North Papua.
