One of the Indonesia government dedieselization program mandated to PT PLN (Persero) is the replacement of diesel power plant to solar power plant with the addition of battery as a merit order baseload targeting small islands with isolated electricity systems. This research was conducted in the Lombok electricity system in Gili Meno, Gili Air and Gili Trawangan (Gili MATRA) because the location of the islands is close together so that the supporting characteristics are still relevant and have more value because it’s an international tourism area. Planning the capacity of solar power plant and battery to replace diesel power plant using the PVsyst V7.3.3 application with trial and error method according to the planning period with 3.14% energy consumption growth and 1.38% peak load growth in Gili Meno requires solar power plant capacity of 555 kWp and a battery capacity of 6,760 Ah (replacing 330 kW diesel power plant capacity) resulting in energy contribution: 2,815,904.35 kWh or IDR12,649,042,332 (difference until IDR1,447,374,835 from replacing diesel power plant), NPV: IDR3,388,717,871 BCR: 1.12, PP: 14.88 years, emission reduction: 8,293.97 tons CO2e and social aspect: 0.672 DALY (8.062 months). In Gili Air, solar power plant capacity of 1,140 kWp and a battery capacity of 14,560 Ah (replacing PLTD capacity of 650 kW) is required, resulting in energy contribution: 5,586,659.35 kWh or IDR25,095,273,820 (difference until IDR2,871,542,908 compared to using diesel power plant), NPV: IDR4,786,305,909, BCR: 1.08, PP: 15.57 years, emission reduction: 16,419.29 tons CO2e and social aspect: 1,330 DALY (15.960 months). In Gili Trawangan, to replace diesel power plant capacity of 1,780 kW, solar power plant capacity of 3,374 kWp and a battery capacity of 12,220 Ah is required, resulting in energy contribution: 16,169,967.93 kW or IDR72,635,495,948 (difference until IDR8,311,363,517 from the use of diesel power plant), NPV: IDR10,149,198,254, BCR: 1.06, PP: 16.04 years, emission reduction: 47,404.61 tons CO2e and social aspect: 3,840 DALYs (46.077 months). The high impact on the study is because most of the previous electrical energy needs were still covered by diesel power plant.
