本研究は、インドネシア・スララヤ石炭火力発電所の均等化発電原価（LCOE）を、国内市場義務（DMO）価格と市場価格の2シナリオで比較した。DMO価格ベースのLCOEは1,008.58 IDR/kWh、市場価格ベースは1,049.52 IDR/kWhであり、市場価格では4.06%増加した。この結果は、石炭価格の仮定が発電コストの解釈に大きく影響することを示し、国内政策に基づく財務コストと経済コストの区別の重要性を強調する。
English
This study compares the Levelized Cost of Electricity (LCOE) of the Suralaya coal-fired power plant under two scenarios: Domestic Market Obligation (DMO) price and market price. The LCOE under DMO is IDR 1,008.58/kWh, while under market price it is IDR 1,049.52/kWh, a 4.06% increase. The findings highlight that coal pricing assumptions significantly affect the financial interpretation of generation costs, and emphasize the need to distinguish between actual financial cost under domestic policy and economic cost based on market price.

日本のGX文脈において
日本では石炭火力発電の位置づけが議論されているが、本論文はインドネシアの石炭価格政策に焦点を当てており、直接的な関連は薄い。ただし、国内価格規制が発電コストの見かけ上の低さを生む仕組みは、日本の石炭火力の経済性評価にも示唆を与える。
In the global GX context
This paper provides empirical evidence on how domestic coal pricing policies (DMO) distort the apparent cost of coal-fired electricity, which is relevant for global energy transition planning and transition finance. It underscores the importance of using market-based cost assumptions when assessing the competitiveness of renewables versus fossil fuels, particularly in emerging economies like Indonesia.

📄 Abstract（原文）
Coal-fired power plants remain an important part of Indonesia’s electricity system because they provide large-scale and reliable baseload supply. However, the perceived low cost of coal-fired electricity is partly influenced by domestic coal pricing policy, particularly the Domestic Market Obligation (DMO) scheme. This study aims to estimate and compare the Levelized Cost of Electricity (LCOE) of the Suralaya coal-fired power plant under two coal price scenarios: the DMO price and the market price. A quantitative case study approach was applied using 2024 operational and financial data. The LCOE was calculated using an annualized cost approach by combining annualized capital cost, operation and maintenance cost, and fuel cost, then dividing total annual cost by annual net electricity generation. The results show that the LCOE based on the DMO coal price is IDR 1,008.58/kWh, while the LCOE based on the market price is IDR 1,049.52/kWh. The use of market price increases the LCOE by IDR 40.94/kWh, or 4.06%, compared with the DMO scenario. These findings indicate that coal pricing assumptions affect the financial interpretation of coal-fired power generation costs. Therefore, generation cost assessment should clearly distinguish between actual financial cost under domestic pricing policy and economic cost based on market price.
