Sebesi Island is one of the small islands in Indonesia. The island has the opportunity to become a famous tourist destination in the future. The island has a beautiful beach panorama. In addition, the island has a lot of natural potentials. To meet its electrical energy needs, the island still uses diesel generators supplied by the state electricity company. The limitations of fossil energy, fuel prices, and transportation costs, as well as the impact of the resulting emissions, are the factors behind the research. Auto-size diesel generator (ADG) is still involved in this research as a form of the energy transition. This study examines the economic and environmental feasibility. The software used is HOMER. The scenarios being modeled are 1. photovoltaic (PV)-biogas generator (GBi), battery (BAT), 2. ADG-PV-GBi-BAT, 3. PV-wind turbine (WT), GBi-BAT, 4. ADG-PV-WT-GBi-BAT, and 5. ADG. There are six parameters used in the economic and environmental assessment, namely net present cost (NPC), cost of energy (COE), operating cost (OC), the renewable fraction (RF), reduction of CO2 emissions, and reduction of fuel oil. All scenarios will be compared with scenario 5 (base case). The simulation results show that the first scenario has the most advantages over the other scenarios. This scenario can be the best recommendation for the implementation of a hybrid energy system (HES) on Sebesi Island, South Lampung, Indonesia. © 2021 IEEE.
