Abstract: Over the years, there has been an increase in energy consumption. In order to combat this increase, more energy production is needed. Since the resources (fossil fuels) on earth for energy production are limited and will end, it is necessary to find alternatives. One of the alternatives are the Trigeneration Systems. In this study, a trigeneration system is implemented in an isolated tropical island and technical-economic feasibility is studied. The preparation of the case study was carried out on the island Pulau Ubin located in Singapore. Initially, two basic energy production systems were implemented, these didn’t contain energy recovery in the engines. Then, a trigeneration system was developed, in which an absorption chiller was used to harness energy that would be dissipated in the engines of base systems. After the implementation of the trigeneration system, an economic analysis of this project was carried out, in order to verify whether or not there is technical-economic feasibility. Given the indicators obtained, the Net Present Value > 0 at the end of the project’s useful life and the Internal Rate of Return > Refresh Rate, it is concluded that the use of a trigeneration system on the island Pulau Ubin is feasible
