Indonesia’s Energy Crisis: Why Coal Wealth Cannot Prevent Blackouts

Indonesia faces persistent electricity blackouts despite possessing some of the world’s largest coal reserves, according to a report by Foreign Policy published July 1, 2026. The energy crisis under President Prabowo Subianto stems from a systemic failure to modernize the national grid and a reliance on inefficient, aging coal plants that cannot meet rising industrial and urban demand.

The paradox of Indonesia’s energy sector is rooted in the gap between its raw resource wealth and its operational infrastructure. While the country is a top global exporter of thermal coal, the state-owned utility company, PLN, struggles with a grid that is prone to failure and unable to distribute power reliably across the archipelago, Foreign Policy reports.

Why is Indonesia experiencing blackouts despite its coal wealth?

The primary cause of the instability is the mismatch between power generation and grid resilience. Foreign Policy notes that the Indonesian government has historically prioritized the construction of new coal-fired power plants over the upgrading of transmission lines. This has created a “bottleneck” where electricity is generated but cannot reach the end-users without triggering system failures.

Further complicating the issue is the age and efficiency of the existing fleet. Many of the coal plants currently powering the country are outdated and suffer from frequent unplanned outages. Because the system lacks sufficient reserve capacity and a flexible grid, a single plant failure often triggers a cascading effect, leading to regional or national blackouts.

How does the current energy policy affect President Prabowo?

President Prabowo Subianto has inherited a volatile energy landscape that threatens his economic growth targets. Foreign Policy reports that these blackouts are becoming a political liability, as reliable power is essential for the foreign investment and industrialization the administration seeks to attract.

The administration faces a tension between two competing goals: maintaining the economic benefits of the coal industry and transitioning to a more stable, diversified energy mix. The reliance on coal provides significant revenue and employment, but the failure to integrate renewable energy or modernize the grid has left the national power supply fragile.

What are the systemic failures in the PLN grid?

The state electricity company, PLN, operates as a monopoly that has struggled to keep pace with Indonesia’s rapid urbanization. According to Foreign Policy, the grid’s inability to handle peak loads is exacerbated by the geographical challenge of connecting thousands of islands, which requires expensive undersea cabling and localized grids that are often underfunded.

The report highlights that the focus on “mega-projects”—massive coal plants—has often ignored the “last mile” of delivery. This means that while the total terawatts generated on paper may seem sufficient, the actual delivery mechanism is too weak to sustain the load without crashing.

What happens next for Indonesia’s power sector?

The Prabowo administration must decide whether to continue subsidizing inefficient coal plants or accelerate the transition to a decentralized grid powered by renewables. Foreign Policy suggests that without a fundamental shift toward grid modernization and the integration of smarter, more flexible energy sources, the country will remain vulnerable to the cycles of blackouts that currently hinder its economic potential.

International pressure to reduce carbon emissions also plays a role, as Indonesia seeks funding for its “Just Energy Transition Partnership” (JETP). However, the report indicates that the immediate priority for the government is stability; the administration must prove it can keep the lights on before it can successfully pivot to a green energy economy.
