Electricity is a very important need to support human life. In the modern world with increasingly sophisticated and rapid technological developments, electricity has a very important and vital role. But unfortunately, this convenience cannot be felt by all humans because the area where they live does not have electricity. In Indonesia, there are at least 346 villages that do not have electricity either from the PLN grid or off- grid. To electrify remote areas and in difficult terrain, an alternative off-grid hybrid power system can be used that utilizes renewable resources and combines it with the use of diesel generators to ensure the availability of electricity supply due to the intermittent renewable energy. This research took place on Matakus Island as a case study because this island does not have electricity. The generation system is divided into two to serve communal/household loads and administrative loads. The most optimal system configuration to supply communal loads consists of 4.86 kW solar PV, 2 kW wind turbines, 6 kW generator sets, and 12 kWh batteries with an LCOE of Rp3,450/kWh and reaching 53.5% RE share. As for administrative loads, the optimal configuration comes from 100% renewable energy, which consists of 2.63 kW solar PV, 1 kW wind turbine, and 8 kWh batteries with an LCOE of IDR 4,075/kWh. The sensitivity analysis conducted shows that the hybrid energy system is robust to changes in component prices and increases in electrical load.
