Transforming Indonesia’scoal dependence into cleanenergy opportunities
Indonesia’s coal phase-out is no longer a policy aspiration, but a strategic and economic necessity.
The country’s electricity system is burdened by oversupply, aging infrastructure, and underutilized coal-fired power plants (CFPPs), many of which operate far below optimal capacity. Despite previous ambitious expansion plans, actual demand growth has lagged, resulting in reserve margins exceeding 39%—significantly higher than the national utility PLN’s own standards.
Systemic Inefficiency and Underperformance
Oversupply has triggered cascading inefficiencies across Indonesia’s power grid. Between 2015 and 2024, the average capacity factor of on-grid CFPPs remained below 70%, indicating persistent underperformance. In 2024, the national average utilization rate for CFPPs—including both PLN and Independent Power Producer (IPP) assets—was approximately 65%.
Even IPP-owned plants operating under take-or-pay power purchase agreements (PPAs), which require delivering at least 80% of installed capacity, have consistently failed to meet this threshold. Over the past three years, IPP-owned CFPPs have operated below 70% utilization, revealing a durable gap between contracted capacity and actual generation.
Mounting Financial Pressure
These operational inefficiencies are translating into a severe financial strain on both PLN and the Government of Indonesia (GOI).
- Rising Generation Costs: Once considered cost-effective, coal’s generation cost has surged by 48%—from IDR 637/kWh in 2020 to IDR 941/kWh in 2024—driven by aging infrastructure and higher operational, maintenance, and compliance costs, despite government-imposed below-market coal price caps.
- Costly Take-or-Pay Contracts: Under existing PPAs, PLN must pay IPPs as if plants are operating at full contracted capacity, regardless of actual output. This payment-output mismatch costs PLN an estimated IDR 33 trillion (USD 2 billion) annually.
- Spiraling Subsidies: In 2024, government allocations for electricity subsidies and compensation jumped 24% to IDR 177 trillion (USD 11 billion), consuming about 33% of PLN’s total revenue. During the same period, electricity sales grew only 6% (from IDR 333 trillion to IDR 353 trillion), underscoring a dangerous divergence between costs and revenue.
The Human Dimension: A Just Transition
Beyond financial and technical concerns, retiring coal plants involves profound social and economic transformation. Phasing out assets without careful planning risks widespread job losses, economic disruption, and community dislocation. Repurposing coal infrastructure—such as transitioning sites to renewable energy hubs or alternative industrial uses—offers a pragmatic and socially responsible pathway.
International Support and the Need for Implementation
Frameworks like the Asian Development Bank’s (ADB) Energy Transition Mechanism (ETM) and the Just Energy Transition Partnership (JETP) offer promising financial and technical support to accelerate Indonesia’s shift away from coal.
However, securing funding alone is insufficient. The real challenge lies in designing and executing a holistic transition strategy that:
- Aligns early retirement plans with grid stability and renewable integration.
- Converts complex financial mechanisms into bankable projects.
- Ensures equity for workers and communities dependent on the coal ecosystem.
- Strengthens policy and regulatory frameworks to enable a smooth, inclusive energy transition.
The shift from coal is now an imperative. How Indonesia navigates this transition—balancing fiscal responsibility, energy security, and social justice—will define its economic and environmental trajectory for decades to come.
