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 on performance of closed cycle of OTEC in Siberut Island, West Sumatera-Indonesia. Siberut Island has a hot and humid tropical rainforest climate, with an annual rainfall of 4,000 mm with temperatures range 22 - 31 0C and humidity averages 81-85%. The study founded that the Siberut island has potential OTEC due to the gradient temperature more than 20 C.
