Meeting these requirements while transitioning to cleaner energy sources creates planning and investment challenges requiring coordinated approaches across multiple stakeholder groups. The plan projects electricity demand growing from 290 TWh in 2024 to over 500 TWh by 2034, necessitating massive infrastructure investment.

Energy Security Challenges and Vulnerabilities

Indonesia's energy security faces multiple challenges including fossil fuel dependency, infrastructure constraints, supply reliability issues, and pricing volatility affecting economic stability and development prospects. Current energy mix remains dominated by coal, oil, and natural gas, creating import dependencies for petroleum products and exposure to global commodity price fluctuations. Coal provides approximately 65% of electricity generation, while oil imports meet 40% of petroleum product demand, creating foreign exchange vulnerabilities.

Infrastructure gaps particularly affect electricity distribution in remote areas and gas pipeline coverage in regions distant from production centers. Transmission losses in Indonesia average 8-9%, compared to 6% in developed countries, representing significant inefficiency. Distribution infrastructure in remote islands relies on expensive diesel generators, creating electricity costs 5-10 times higher than grid-connected areas. Gas pipeline infrastructure covers only major industrial centers, limiting gas utilization for power generation and industrial applications in many regions.

Energy poverty persists in various Indonesian regions where households lack reliable electricity access, constraining economic opportunities and quality of life. Research documents how energy disruptions perpetuate poverty cycles by limiting productive activities during power outages, restricting children's study time, and preventing home-based business operations. Addressing these disparities requires targeted infrastructure investment and policy attention ensuring energy access reaches underserved populations. Rural electrification programs have achieved 99% electrification rate nationally, but reliability and affordability remain major concerns.

Fuel subsidy policies aim to maintain affordability but create fiscal burdens consuming significant government resources. Subsidy reforms face political and social challenges given household sensitivity to energy price increases, requiring careful design balancing affordability, fiscal sustainability, and efficiency incentives. Past subsidy reduction attempts in 2005, 2008, and 2014 triggered protests and inflation concerns, demonstrating political sensitivity. International experience suggests gradual approaches with targeted compensation for vulnerable groups can navigate these tradeoffs more successfully than abrupt subsidy removal.

Energy security policy responses include domestic resource development, renewable energy expansion, efficiency improvements, and strategic reserve establishment. The National Energy Policy establishes targets for energy mix diversification and self-sufficiency enhancement, though implementation progress varies across different energy subsectors and regions. Policy aims for 23% renewable energy share by 2025 and 31% by 2050, though current penetration remains below 12%, indicating acceleration needed.

Green Transition Planning and Renewable Energy Pathways

Indonesia's green transition plan establishes pathways for increasing renewable energy share while maintaining economic growth momentum and energy affordability. The Indonesia Energy Transition Outlook 2025 analyzes various scenarios balancing emission reduction ambitions with development priorities, considering technology options, investment requirements, and policy instruments supporting transition implementation.³

Renewable energy potential in Indonesia includes geothermal resources exceeding 23 GW from volcanic geology, hydroelectric opportunities of 75 GW in mountainous regions, solar resources throughout equatorial archipelago, wind potential in specific locations, and bioenergy from agricultural and forestry residues. Current renewable energy penetration remains limited despite this potential, with barriers including upfront capital costs, grid integration challenges, regulatory complexities, and competition from established fossil fuel infrastructure.

Geothermal development faces long lead times of 7-10 years and high exploration risks, though Indonesia ranks second globally in installed capacity at 2.3 GW. Hydroelectric development encounters environmental and social concerns regarding dam construction and community displacement. Solar photovoltaic deployment accelerates with declining costs, reaching grid parity in many regions, though intermittency requires battery storage or backup generation. Wind resources concentrate in eastern Indonesia and specific coastal areas, with limited deployment to date requiring technology adaptation and infrastructure investment.

Technology cost trends favor renewable energy deployment, with solar PV costs declining 90% over past decade and battery storage costs falling 85%, making renewable energy increasingly competitive with fossil fuels. However, Indonesia's specific challenges include land availability for large-scale solar farms, grid integration costs for variable generation, and financing availability at competitive rates for capital-intensive projects.
