Abstract

Amid Indonesia's push to expand renewable energy, this study evaluates the long-term impact of the depletion premium—a revenue-neutral policy that reallocates 25 % of fossil fuel tax revenue to support solar photovoltaic (PV) development—using 15 years of national data. An optimization model, calibrated with World Bank (2017) parameters, compares two strategies: raising subsidies and improving PV efficiency. Results indicate that a 5 % subsidy increase enhances capital efficiency and solar generation but dampens new investment. By contrast, a 5 % improvement in PV efficiency delivers greater overall economic returns. The findings suggest that combining targeted early subsidies with efficiency improvements can accelerate solar expansion, reduce dependence on fossil fuels, and advance Indonesia's renewable energy goals while maintaining fiscal sustainability.

印尼太阳能补贴：评估化石燃料耗竭溢价作为收入中性政策工具

在印尼推动扩大可再生能源的过程中，本研究利用15年的国家数据评估了枯竭补贴的长期影响。枯竭补贴是一项收入中性政策，将25%的化石燃料税收收入重新分配给太阳能光伏（PV）的发展。使用世界银行（2017）的参数校准的优化模型比较了两种策略：提高补贴和提高光伏发电效率。结果表明，5%的补贴增加提高了资本效率和太阳能发电，但抑制了新的投资。相比之下，光伏发电效率提高5%就能带来更大的整体经济回报。研究结果表明，将有针对性的早期补贴与提高效率相结合，可以加速太阳能的发展，减少对化石燃料的依赖，并在保持财政可持续性的同时推进印尼的可再生能源目标。

期刊介绍： Utilities Policy is deliberately international, interdisciplinary, and intersectoral. Articles address utility trends and issues in both developed and developing economies. Authors and reviewers come from various disciplines, including economics, political science, sociology, law, finance, accounting, management, and engineering. Areas of focus include the utility and network industries providing essential electricity, natural gas, water and wastewater, solid waste, communications, broadband, postal, and public transportation services. Utilities Policy invites submissions that apply various quantitative and qualitative methods. Contributions are welcome from both established and emerging scholars as well as accomplished practitioners. Interdisciplinary, comparative, and applied works are encouraged. Submissions to the journal should have a clear focus on governance, performance, and/or analysis of public utilities with an aim toward informing the policymaking process and providing recommendations as appropriate. Relevant topics and issues include but are not limited to industry structures and ownership, market design and dynamics, economic development, resource planning, system modeling, accounting and finance, infrastructure investment, supply and demand efficiency, strategic management and productivity, network operations and integration, supply chains, adaptation and flexibility, service-quality standards, benchmarking and metrics, benefit-cost analysis, behavior and incentives, pricing and demand response, economic and environmental regulation, regulatory performance and impact, restructuring and deregulation, and policy institutions.
