Executive Summary

Indonesia stands at a critical juncture in its energy trajectory, balancing ambitious clean energy commitments with entrenched structural constraints that complicate implementation. Government officials have repeatedly affirmed Indonesia's commitment to renewable energy development at international forums including the IEA Summit, positioning the nation as active participant in global climate action.¹ These high-level commitments translate into policy targets including achieving net zero emissions by 2060, substantially increasing renewable energy penetration in the power sector, and reducing dependence on fossil fuels driving current energy system.

However, detailed analysis of implementation plans reveals significant gaps between stated ambitions and actual policy execution. The Indonesia Energy Transition Outlook 2025 documents progress while highlighting persistent challenges in translating policy commitments into concrete actions and investments.² PLN's electricity supply business plan (RUPTL) for 2025-2034 shows continued prioritization of fossil fuel capacity additions, leading observers to characterize the approach as "fossils first, renewables later" despite stated renewable energy commitments.⁵

Recent policy developments including Presidential Regulation No. 40 of 2025 on National Energy Policy, enacted in September 2025, establish comprehensive frameworks addressing energy supply, demand management, and transition pathways.¹² These regulatory advances create foundations for coordinated action, yet successful implementation requires addressing structural constraints including financing gaps, institutional capacity limitations, fossil fuel subsidy dependencies, and regulatory uncertainties affecting investment decisions. Understanding these challenges alongside identifying pathways for effective execution proves essential for Indonesia achieving its clean energy ambitions while maintaining energy security and economic development objectives.

National Energy Policy Framework and Recent Regulatory Developments

Indonesia's energy policy architecture combines long-standing frameworks with recent regulatory updates establishing comprehensive approaches to energy transition. The National Energy Policy (Kebijakan Energi Nasional) codified in Government Regulation No. 79 of 2014 set initial direction for energy mix diversification and renewable energy development.⁴ This foundational regulation established targets for renewable energy contribution to primary energy supply, though subsequent implementation revealed gaps between policy aspirations and actual achievements.

Presidential Regulation No. 73 of 2023 on National Energy Management Strategy provided updated strategic direction, while the newly enacted Presidential Regulation No. 40 of 2025 represents most recent comprehensive policy statement on national energy direction.¹⁴ These successive regulations demonstrate ongoing policy attention to energy transition, with each iteration attempting to address implementation challenges identified in previous frameworks while adapting to changing domestic and international circumstances.

The Ministry of Energy and Mineral Resources leads policy formulation and implementation, with organizational structure formalized through Presidential Regulation No. 169 of 2024.¹³ Directorate General of Renewable Energy and Energy Conservation (Ditjen EBTKE) holds specific mandates for renewable energy programs, with performance reports documenting activities and achievements toward stated objectives. Coordination across multiple agencies including Ministry of Finance, State-Owned Enterprise Ministry, and provincial governments remains critical challenge requiring sustained attention to institutional mechanisms supporting integrated action.

Policy coherence between different regulations and consistency over time significantly influence investment confidence and project execution. Frequent regulatory changes or contradictions between different policy instruments create uncertainty deterring long-term investments required for energy infrastructure. Achieving stable, predictable policy environments while maintaining flexibility for adaptation to changing circumstances represents ongoing governance challenge.

Renewable Energy Targets and Current Progress

Indonesia's renewable energy targets have been subject to various formulations across different policy documents and timeframes. Recent analysis suggests that achieving 100% renewable electricity within 10 years requires concrete plans and policies translating ambition into actionable programs with adequate resource allocation and implementation timelines.³ This ambitious goal contrasts with current trajectory where fossil fuels continue dominating new capacity additions according to electricity supply planning documents.

Progress assessment through the Indonesia Energy Transition Outlook provides systematic evaluation of advances and shortfalls against stated objectives. While certain renewable energy technologies including solar and geothermal show expansion, overall pace remains insufficient for meeting long-term targets given current growth rates and continued fossil fuel investments. The gap between ambition and execution manifests through delayed project implementations, financing constraints, and regulatory barriers affecting renewable energy development timelines.

The Climate Transparency Report provides independent assessment of Indonesia's renewable energy development within power sector context, documenting achievements while identifying areas requiring strengthened action to align with climate commitments.⁴ International observers note disconnect between stated ambitions and implementation realities, with concerns that continued fossil fuel prioritization in near-term planning creates lock-in effects complicating future transition efforts.

Realizing ambitious renewable energy goals requires new approaches addressing identified barriers through comprehensive strategies combining policy reforms, financing innovations, institutional strengthening, and stakeholder engagement.⁷ This includes learning from international experience while adapting solutions to Indonesian contexts, accelerating technology deployment through streamlined processes, and mobilizing capital at scales required for achieving stated objectives within timeframes established by climate science and economic competitiveness imperatives.

RUPTL 2025-2034: Fossil Fuels vs. Renewables Priority

PLN's Rencana Usaha Penyediaan Tenaga Listrik (RUPTL) for 2025-2034 serves as concrete implementation roadmap for power sector development, translating policy objectives into specific capacity addition plans, investment programs, and infrastructure projects. Analysis of this planning document reveals tensions between stated renewable energy commitments and actual capacity addition priorities, with fossil fuel plants continuing to dominate near-term development pipeline despite climate and renewable energy policy objectives.

Critical examination characterizes the RUPTL as "fossils first, renewables later" approach, documenting how coal and gas-fired power plants receive priority for development in immediate years while renewable energy projects concentrate in later portions of planning period.⁵ This sequencing creates multiple risks including fossil fuel infrastructure lock-in through long-lived assets, stranded asset potential if early retirement becomes necessary for climate goals, continued emissions during critical decade for climate action, and delayed learning and cost reductions from scaled renewable deployment.

The disconnect between RUPTL priorities and stated renewable energy commitments raises questions about policy coherence and implementation credibility. While PLN cites technical, financial, and operational considerations justifying fossil fuel development, critics argue that these concerns could be addressed through alternative approaches prioritizing renewable energy deployment while managing transition risks through grid modernization, energy storage, and demand flexibility rather than extending fossil fuel dependence.

Revising RUPTL to align with climate commitments and renewable energy targets represents critical policy priority. This requires addressing underlying constraints that drive current fossil fuel prioritization including PLN's financial health, regulatory frameworks for renewable energy integration, transmission infrastructure adequacy, and institutional capacity for managing high-penetration renewable electricity systems. International experience demonstrates feasibility of rapid renewable energy scaling when appropriate policies, financing, and institutions align to support transition.

Structural Constraints Limiting Clean Energy Deployment

Multiple structural factors constrain Indonesia's renewable energy deployment pace despite favorable policy rhetoric and technical potential. These constraints span financial, institutional, regulatory, and political dimensions, creating interconnected barriers requiring comprehensive approaches for effective removal. Understanding these structural impediments proves essential for designing interventions that address root causes rather than symptoms of slow renewable energy progress.

Financing constraints emerge as primary barrier, with capital requirements for renewable energy transformation exceeding available domestic resources while international finance faces perceived risks limiting deployment speed and scale. Indonesian financial institutions often lack familiarity with renewable energy projects, leading to conservative lending approaches or requirement for extensive guarantees increasing project costs. Development of green finance instruments and sustainable investment frameworks remains nascent compared to needs, though recent initiatives including green taxonomy development show progress toward addressing these gaps.

Institutional capacity limitations affect both policy development quality and implementation effectiveness. Regulatory agencies may lack technical expertise for evaluating complex renewable energy proposals, leading to delays, inconsistent decisions, or overly conservative approaches. PLN as dominant power sector actor faces organizational challenges adapting to distributed generation, variable renewable resources, and changing utility business models required for clean energy transition. Building institutional capacity through training, organizational development, and potentially structural reforms represents necessary but time-consuming undertaking.

Regulatory uncertainties create investment risks discouraging commitments of capital and resources required for large-scale renewable energy deployment. Frequent policy changes, unclear implementation procedures, inconsistent enforcement, and unpredictable pricing mechanisms all contribute to risk perceptions limiting investment appetite. Establishing stable, predictable regulatory environments with transparent processes and long-term policy commitments would significantly improve investment climate for renewable energy development.

Execution Risks and Implementation Challenges

Translation of policies into operational reality faces substantial execution risks spanning project development challenges, infrastructure constraints, stakeholder coordination difficulties, and external factors beyond direct government control. These implementation obstacles can delay or derail even well-designed policies, making execution focus as critical as policy formulation for achieving renewable energy objectives.

Project development challenges include site identification and land acquisition, permitting and approval processes, grid connection logistics, financing mobilization, technology procurement, construction management, and commissioning. Each stage presents potential delays or obstacles that cumulate to extend development timelines substantially beyond initial projections. Streamlining these processes through one-stop services, standardized procedures, and capacity building in implementing agencies could significantly accelerate deployment.

Grid infrastructure limitations constrain renewable energy integration, particularly for variable resources like solar and wind requiring transmission capacity, system flexibility, and potentially energy storage for reliable integration. Indonesia's transmission network shows gaps in coverage and capacity affecting ability to connect renewable projects to demand centers. Grid modernization investments including smart grid technologies, transmission expansion, and flexibility resources require substantial capital and time for implementation, creating near-term bottlenecks for renewable energy deployment even as policy environments improve.

Stakeholder coordination across multiple government agencies, levels of government, state-owned enterprises, private developers, international partners, and affected communities adds complexity to project execution. Misalignment of objectives, communication gaps, conflicting mandates, or simply coordination failures can delay projects substantially. Establishing effective coordination mechanisms including clear responsibility matrices, regular communication forums, dispute resolution processes, and accountability frameworks improves implementation effectiveness while reducing friction losses from organizational interfaces.

Economic Competitiveness and Trade Considerations

International trade dynamics increasingly link clean energy adoption to economic competitiveness, with carbon border adjustment mechanisms and sustainability requirements affecting market access for Indonesian exports. Major trading partners including the European Union implement policies imposing costs on carbon-intensive imports, creating economic incentives for emissions reductions throughout production chains. For Indonesia as export-oriented economy, renewable energy adoption becomes not only environmental imperative but also economic necessity for maintaining competitiveness.⁶

Clean energy expansion can drive economic growth through multiple channels including manufacturing sector development for renewable energy equipment, job creation in installation and maintenance, export opportunities in growing global markets, reduced energy import dependencies, and improved terms for international investment and trade relationships. Analysis suggests that Indonesia's clean energy expansion presents opportunity rather than merely cost, with proper policy frameworks capturing economic benefits alongside environmental objectives.³

Investment attractiveness increasingly factors environmental and sustainability performance, with international investors applying ESG (Environmental, Social, Governance) criteria screening investments. Countries demonstrating commitment to clean energy transition through credible policies and implementation track records attract more favorable investment consideration, while those lagging face potential capital access constraints. This investment dimension adds to trade considerations in linking Indonesia's economic future to renewable energy adoption pace and credibility.

Industrial policy integration ensures renewable energy deployment aligns with broader economic development strategies including manufacturing development, export promotion, and employment generation. Coordinated approaches linking renewable energy expansion with industrial park development, special economic zones, and sector-specific strategies maximize economic benefits while advancing clean energy objectives. This integrated thinking contrasts with siloed approaches treating energy policy separately from economic development, recognizing their fundamental interconnections.

Financing Mechanisms and Investment Mobilization

Achieving Indonesia's clean energy ambitions requires mobilizing substantial capital from diverse sources including domestic savings, international development finance, commercial banking, private equity, and innovative financing instruments. Total investment requirements span tens to hundreds of billions of dollars across generation, transmission, distribution, and enabling infrastructure, exceeding government fiscal capacity and requiring private sector participation at scale alongside strategic public investment.

Recent initiatives attempt to address financing gaps through mechanisms including the Green Energy Buyers Dialogue connecting renewable energy developers with corporate purchasers, JETP (Just Energy Transition Partnership) mobilizing international support for accelerated transition, green bond issuance by government and corporations, blended finance structures combining public and private capital, and targeted development partner programs supporting specific technologies or regions.⁹

OECD analysis of clean energy finance and investment policy in Indonesia identifies opportunities and barriers affecting capital mobilization, recommending measures to improve investment climate including regulatory streamlining, risk mitigation instruments, pricing transparency, and institutional capacity building.² Implementing these recommendations could substantially improve financing flows, though sustained commitment and follow-through prove essential for realizing potential benefits from improved policy frameworks.

Investment mobilization efforts must address both supply-side factors including available capital and investor appetite, and demand-side factors including bankable project pipelines and investable opportunities. Project preparation facilities supporting development from concept through financial close help create investable projects, while capacity building for local developers and financial institutions strengthens domestic capabilities for sustained clean energy investment beyond initial international support phases.

Just Transition Principles and Social Dimensions

Energy transition creates both opportunities and challenges for communities and workers currently dependent on fossil fuel industries, necessitating attention to just transition principles ensuring equitable distribution of transition benefits and costs. Coal mining regions face particular vulnerability where industry decline threatens employment, local government revenues, and community economic foundations. Managing these transitions requires proactive approaches supporting economic diversification, worker retraining, social protection, and community development rather than abandoning affected populations to market forces.

Analysis of just transition challenges and approaches in Indonesian context documents concerns from affected stakeholders while identifying pathways for managed transitions supporting affected communities through change.⁹ International experience demonstrates importance of early engagement, adequate resources, genuine participation in decision-making, and long-term commitment to affected regions rather than short-term responses insufficient for fundamental economic restructuring requirements.

Beyond coal region transitions, broader social dimensions include ensuring energy access benefits reach all population segments including rural and low-income communities, maintaining energy affordability during transition periods, creating quality employment in renewable energy sectors, and ensuring women and marginalized groups participate in clean energy economy opportunities. Gender-responsive and socially inclusive approaches throughout policy design and implementation strengthen social acceptance while advancing equity objectives alongside environmental goals.

Political economy factors significantly influence transition pace and approach, with vested interests in fossil fuel industries resisting change while renewable energy constituencies remain relatively weak given sector nascency. Building political coalitions supporting clean energy transition requires demonstrating tangible benefits including jobs, economic opportunities, improved energy access, and environmental quality while managing opposition through fair treatment of affected groups and transparent processes building legitimacy for necessary changes.

International Cooperation and Development Partnerships

Indonesia's clean energy transition receives substantial international support through bilateral and multilateral partnerships providing financing, technical assistance, technology transfer, and capacity building. These international engagements range from project-specific support to comprehensive programs like JETP addressing multiple dimensions of transition challenge through coordinated intervention packages combining various instruments and support modalities.

Development partner engagement brings not only financial resources but also technical expertise, global best practice, convening power for stakeholder coordination, and quality assurance through adherence to international standards. However, effective partnerships require Indonesian ownership, alignment with national priorities, capacity building for sustainability beyond external support, and coordination among multiple partners avoiding duplication while ensuring complementarity of different programs.

Regional cooperation within ASEAN creates opportunities for learning from neighboring countries' experiences, coordinating approaches to common challenges, developing regional supply chains and markets, and potentially pursuing cross-border infrastructure projects enabling resource sharing across national boundaries. Indonesia's leadership position within ASEAN provides platform for advancing regional clean energy agenda while accessing support and collaboration opportunities with regional neighbors.

Technology transfer remains critical dimension of international cooperation, with Indonesian access to advanced renewable energy technologies, manufacturing capabilities, and technical know-how depending substantially on partnerships with international companies and institutions possessing these capabilities. Balancing technology import with domestic capability development requires strategic approaches including local content requirements, joint venture arrangements, licensing agreements, and investments in domestic research and development building indigenous innovation capacity.

Pathways Forward: Recommendations for Accelerated Implementation

Accelerating Indonesia's clean energy transition from ambition to reality requires comprehensive strategies addressing identified structural constraints and execution risks through coordinated actions across multiple dimensions. Priority recommendations span policy and regulatory improvements, financing mobilization, institutional strengthening, stakeholder engagement, and sustained political commitment maintaining focus through inevitable challenges and transitions.

Immediate priorities include revising RUPTL to prioritize renewable energy over fossil fuels in near-term capacity additions, streamlining project permitting and approval processes reducing unnecessary delays, mobilizing finance through innovative instruments and risk mitigation mechanisms, and strengthening institutional capacity for renewable energy planning and implementation. Medium-term actions focus on grid modernization enabling high renewable penetration, workforce development for clean energy sectors, regional economic diversification supporting just transition, and building domestic supply chains reducing import dependencies. Long-term success requires sustained policy commitment across political cycles, adequate resource allocation matching stated priorities, and continuous learning and adaptation improving implementation effectiveness over time.

Success requires treating clean energy transition as whole-of-government priority with coordination across ministries, levels of government, and public institutions. Establishing high-level coordination mechanisms with authority to drive action, resolve conflicts, and ensure accountability strengthens implementation compared to fragmented approaches where clean energy remains responsibility of energy ministry alone without broader governmental commitment and support.

Monitoring progress through transparent reporting on indicators including renewable capacity additions, investment flows, policy milestone achievements, and emission trajectories enables adaptive management while building accountability for commitments made. Regular assessment comparing actual progress against stated targets identifies gaps requiring corrective action, while celebrating achievements maintains momentum and demonstrates credibility supporting continued support from stakeholders and international partners.

Conclusions

Indonesia stands at critical crossroads in its energy future, with ambitious clean energy commitments confronting substantial structural constraints and execution risks that complicate implementation. Recent policy developments including Presidential Regulation No. 40 of 2025 establish comprehensive frameworks, yet analysis of implementation plans particularly RUPTL 2025-2034 reveals continued fossil fuel prioritization despite stated renewable energy objectives. This gap between ambition and execution creates credibility concerns while risking economic competitiveness impacts from delayed clean energy adoption.

Addressing structural constraints requires coordinated action across financing, institutions, regulations, and political economy factors currently limiting clean energy deployment pace. No single intervention proves sufficient; success depends on comprehensive strategies tackling multiple barriers simultaneously while building enabling conditions for sustained progress. International experience demonstrates feasibility of rapid renewable energy scaling when appropriate policies, financing, and institutions align, though Indonesia must adapt these lessons to its specific contexts rather than assuming direct transferability of approaches from other countries.

Execution risks spanning project development challenges, infrastructure constraints, and coordination difficulties require sustained management attention alongside policy formulation. Converting policies into operational realities demands detailed implementation planning, adequate resource allocation, capacity building, and persistent follow-through overcoming inevitable obstacles encountered during complex transitions. Just transition principles ensuring equitable distribution of costs and benefits strengthen social acceptance supporting sustained commitment required for fundamental energy system transformation.

The stakes extend beyond environmental objectives to encompass economic competitiveness, energy security, and Indonesia's position in increasingly carbon-conscious global economy. Delayed action risks stranded fossil fuel assets, missed opportunities from renewable cost declines, trade disadvantages from carbon border adjustments, and reduced investment attractiveness from sustainability-focused capital. Conversely, decisive action positioning Indonesia as regional clean energy leader creates economic opportunities while advancing climate and development objectives. Success requires moving from rhetoric to results through sustained commitment, adequate resources, effective implementation, and willingness to confront vested interests resisting necessary changes for Indonesia's sustainable energy future.
