The need for clean energy to drive net zero emissions by 2060 is critical for dedieselization efforts. Solutions involving multiple renewable energies face reliability challenges due to intermittency. Pulau Bunguran is an island heavily reliant on diesel power generation (100% diesel ratio). In the first phase of dedieselization, no existing PLTD facilities from Pulau Bunguran will be utilized. A capacity of up to 21.32 MW requires a clean and reliable power generation solution. Nuclear power plants, particularly microreactor technology, offer a viable reference. This study evaluates three microreactor variations (microreactor without Thermal Energy Storage (TES), with TES, and optimized with Solar hybrid). The microreactor without TES achieves high efficiency up to 41.7% with a capacity factor of 70%. Optimized TES microreactors address flexible load requirements through thermal energy storage conversion. Energy penetration exceeds 60%, with microreactor capacity factors reaching 96.7%. Adjustment of TES controls is necessary to manage various constraints. The minimum load is constrained to 40% to prevent temperature instability in molten salt. Charging control employs constant power mode, while discharging uses flexible load mode. The Levelized Cost of Electricity (LCOE) for the new system reaches $0.138/kWh with solar hybrid optimization, down from the original $0.41/kWh with existing diesel power plant.
