インドネシア最外縁のエンガノ島では、ディーゼル発電（PLTD）の燃料費高騰とCO2排出が課題となっている。本研究はPV・ディーゼル・蓄電池を組み合わせたハイブリッド構成をHOMER等で最適化し、PV1,005kW・ディーゼル250kW・蓄電池594台の構成がNPC約317億ルピア、COE約1,999ルピア/kWhで最も経済的と示した。再エネ比率91%を達成し、環境持続性も高い。
English
Enggano Island relies on costly diesel power, limiting supply to 16 hours/day and generating high CO2 emissions. This study optimizes hybrid PV-diesel-battery configurations using net present cost and cost of energy. The optimal setup (1,005 kW PV, 250 kW diesel, 594 batteries) yields 1,576,115 kWh/year at an NPC of Rp31.7 billion and COE of Rp1,998.75/kWh, with a 91% renewable fraction.

日本のGX文脈において
日本の離島（離島振興法・再エネ導入）におけるディーゼル依存脱却とマイクログリッド設計に示唆を与える。ただし制度・開示面の議論はなく、技術経済分析に留まる。
In the global GX context
Adds empirical evidence on hybrid mini-grid optimization for outermost islands, relevant to global energy transition and SDG7 discussions, though it does not engage with disclosure frameworks like TCFD/ISSB.

📄 Abstract（原文）
Enggano Island is one of the outermost regions using diesel power plants (Pembangkit Listrik Tenaga Diesel - PLTD) as their source of electrical energy. PLTD, which began its operations in 2017, consists of three units of generator machines capable of generating 730 kW of power, with a total of 1,050 customers and electricity needs of 1,097,883 kWh/year. Although power plants are readily available, in reality, the electricity problem is still a fundamental unresolved issue on the island. The average fuel consumption to operate a PLTD is 21 tons/month or Rp582,757,000.00 per month, assuming the fuel price is Rp9,800.00 per liter. The high operating expenses resulted in electricity only being supplied for sixteen hours per day. The utilization of PLTD also produces very high carbon dioxide (CO2) emissions. It is not in line with the government's commitment to transition to net zero emissions by 2060. The utilization of new renewable energy (Energi Baru dan Terbarukan - EBT), targeted at 23% by 2025, is still not optimal. The paper aims to discover Enggano Island's optimal hybrid power plant configuration in terms of technicality and economic feasibility. Economic feasibility is reviewed using the net present cost (NPC), and cost of economic (COE) approaches. In addition, sustainability analysis is also carried out from environmental aspects. From this study, the most optimal configuration based on the lowest system cost was configuration 2 of scenario 1, consisting of photovoltaic (PV) 1,005 kW, diesel of 250 kW, and 594 battery units. This configuration can produce electricity of 1,576,115 kWh/year with an NPC value of Rp31.7 billion rupiah and a COE value of Rp1,998.75 per kWh. This configuration also has good environmental sustainability because it has a renewable fraction value of 91%. ; Pulau Enggano merupakan salah satu wilayah terluar yang menggunakan pembangkit listrik tenaga diesel (PLTD) sebagai sumber energi listriknya. PLTD yang mulai beroperasi sejak tahun 2017 ini terdiri atas tiga unit mesin ...
