Indonesia's Declining Coal Output: Implications for Energy Security and Renewable Investment Opportunities

Indonesia's coal industry, once a cornerstone of its economic and energy strategy, is now at a crossroads. Domestic production hit a record 836 million tons in 2024, according to a BNN Bloomberg report, yet export volumes have plummeted by 6.33% year-on-year in the first half of 2025, with revenues dropping 21.09% to $11.97 billion, per an APBI-ICMA analysis. This decline reflects a global energy transition and shifting dynamics in key markets like China and India, which are prioritizing domestic coal production and renewables, as Reuters reports. For investors, this signals a critical inflection point: the need to reallocate capital from a faltering coal sector to emerging opportunities in clean energy and critical minerals.

The Drivers of Decline: Global Oversupply and Shifting Demand

Indonesia's coal exports have long relied on demand from China and India, which together accounted for nearly two-thirds of its coal shipments in 2023, according to a Mordor Intelligence report. However, both nations are now reducing their reliance on Indonesian imports. China, the world's largest coal importer in 2024, is accelerating its clean energy transition, with renewables accounting for 75% of new power generation in 2024, the BNN Bloomberg report noted. Similarly, India's coal imports fell by 8.4% from April to December 2024 as it boosted domestic production and expanded coal inventories, the APBI-ICMA analysis found.

This shift is compounded by global oversupply. Indonesia's domestic production-projected to exceed 700 million tons in 2025-has outpaced demand, driving down export prices to $64.99 per ton in 2025, a significant drop from historical averages, the APBI-ICMA analysis shows. The BNN Bloomberg report described this oversupply as a "perfect storm" for Indonesian coal producers, squeezing margins and exposing the sector's vulnerability to market volatility.

Diversification Efforts: A Mixed Bag of Strategies

Faced with declining coal demand, some Indonesian firms are pivoting to non-coal sectors. Adaro Energy, the country's largest coal producer, has invested in aluminum production and renewable energy projects, and Harum Energy is repositioning itself in nickel smelting to capitalize on the electric vehicle battery boom, the APBI-ICMA analysis notes. These moves align with global trends: nickel demand is expected to grow 15-fold by 2040, driven by EVs and energy storage, according to the Mordor Intelligence report.

However, not all companies are embracing diversification. Bayan Resources and Geo Energy Resources are expanding coal production by 58 million tons combined, raising concerns about environmental sustainability and policy alignment. This divergence highlights a broader challenge: while some firms are adapting to the energy transition, others remain entrenched in a coal-dependent model, risking long-term viability.

Policy Uncertainty and the Path to a Just Transition

Indonesia's regulatory landscape further complicates the transition. Regulation 10/2025, introduced in April 2025, aims to reduce coal dependence and achieve net-zero emissions by 2060, according to the APBI-ICMA analysis. The policy includes early retirement of coal plants and incentives for carbon capture and storage (CCS) technologies. Yet, the BNN Bloomberg report noted that the regulation has been criticized for excluding civil society and labor groups, raising concerns about a "just transition" for the 267,000 workers employed in the coal sector.

This policy ambiguity creates both risks and opportunities. For investors, the lack of clarity around coal phase-out timelines and renewable incentives introduces regulatory risk. However, it also opens a window for strategic investment in sectors poised to benefit from Indonesia's energy transition, such as solar, wind, and critical minerals.

Renewable Investment Opportunities: A Strategic Reallocation

The energy transition in Indonesia is not just a necessity-it's an opportunity. The country's abundant solar and geothermal resources, combined with its strategic location in the "Battery Belt" of Southeast Asia, position it as a key player in the global clean energy supply chain, the Mordor Intelligence report observes. For instance, nickel and aluminum, critical for EV batteries and renewable infrastructure, are already seeing increased investment. Harum Energy's pivot to nickel smelting and Adaro's renewable projects demonstrate the potential for sector reallocation.

Moreover, Indonesia's domestic coal production capacity could be repurposed for clean energy. Coal-fired power plants, for example, could be retrofitted for hydrogen production or integrated with CCS technology, the BNN Bloomberg report suggested. Such transitions require upfront capital but offer long-term returns in a decarbonizing world.

Risks and Considerations for Investors

While the shift from coal to renewables presents compelling opportunities, investors must navigate several risks. First, Indonesia's coal sector remains politically influential, with insider control of companies and high royalties creating barriers to entry for new players, the BNN Bloomberg report and APBI-ICMA analysis both highlight. Second, the pace of the energy transition is uncertain. If global coal demand rebounds or policy support for renewables falters, investments in clean energy could face headwinds.

Additionally, the social and environmental costs of coal must be addressed. A just transition requires not only policy reforms but also private-sector collaboration to retrain workers and support affected communities, the APBI-ICMA analysis recommends. Investors who prioritize ESG (Environmental, Social, and Governance) criteria will be better positioned to mitigate these risks.

Conclusion: A Strategic Pivot in Emerging Markets

Indonesia's coal industry is a microcosm of the global energy transition. As demand for coal wanes, the country faces a pivotal choice: cling to a declining sector or reallocate capital to renewables and critical minerals. For investors, the latter path offers not only ethical alignment but also financial resilience. By supporting firms like Adaro and Harum Energy, and engaging with Indonesia's evolving policy landscape, investors can help shape a sustainable future while capturing growth in emerging markets.

The window for strategic reallocation is narrowing. As the world moves toward net-zero, Indonesia's ability to pivot will determine not only its energy security but also its economic trajectory in the 21st century.
