The Indonesian region, especially Southeast Sulawesi, has significant potential for renewable energy, especially biomass and solar. Biomass, the fuel of a biomass power plant (BPP) derived from the conversion of biological material, has a high potential in Southeny Sulawesia, especially from residues such as oil palm and coconut. Solar power plants (PV) convert solar energy into electricity. As a renewable source of energy, biomass and solar energy offer alternatives to power generation, potentially increasing power supply, especially for Baubau isolated power systems. The study uses reliability recursive methods to calculate Loss of Load Probability (LOLP) and Loss Of Load Expectation. (LOLE). By 2023, the government is planning to build a Baubau 3 x 9.78 MW PLTMG to improve reliability. In the Bau-Bau power system, consisting of 14 power plants with a peak load of 40.25 MW by 2022, LOLE recorded 1.02 days/year. By adding PLTBm with a capacity of 1.34 MW, LOLE decreased to 0.71 days/ year, or 30.39%. PLTS is needed to increase LOLP at peak loads, which are still high above standard. Based on the Homer Pro simulation, the optimum value for PLTS was 9.373 kW, the battery was 26.972 kWh, and the inverter was 13.906 kW. On the PLTS system, Net Present Cost (NPC) was $166 million and Levelized Cost of Energy (LCOE) $2.63 per kWh.
