The use of fossil energy has continuously resulted in reduced reserves of energy resources, and many negative impacts such as air pollution that led to global warming. As a remedy to overcome it is developed and attempted to use renewable energy from a source of solar radiation or so-called solar power. According to IRENA calculations in 2030 Indonesia has the potential of solar photo voltaic energy of 532.6 GW of which 140.9 GW is located in the Maluku and Papua. This research is aimed to measure the possibility or risk impact of floating solar power plant development in Kei Kecil Island, Southeast Maluku as risk assessment using Monte Carlo method so that risk can be expected to be handled properly. The scope of this research are technical, economic, commercial, organizational and political aspects. According to the calculation result that the total risk is 4.12 which is in ALARP zone and after simulation got value 3,89 with the most influential risk factor is Cost of Energy (CoE). The renewal of this research is solar panel technology in marine waters with the location of Kei Kecil Island as a remote area in Indonesia.
