Indonesia has unveiled an ambitious plan to scale up its wind power capacity to 5 gigawatts (GW) by 2030. The target represents a substantial leap from the country’s current installed capacity of only 152.3 megawatts (MW). It signals the government’s determination to diversify energy sources, cut carbon emissions, and reduce reliance on coal, which still dominates the nation’s power grid.
The announcement is part of the revised Electricity Supply Business Plan (RUPTL 2025–2035), a roadmap outlining the national energy strategy. For Indonesia, the largest economy in Southeast Asia, the target is both a domestic necessity and a geopolitical signal, as the country seeks to position itself as a key player in the global energy transition.
Experts say the move is also designed to unlock international financing through the Just Energy Transition Partnership (JETP), a $20 billion fund designed to accelerate decarbonization in developing nations.
National Ambition and Energy Transition Pathway
Indonesia’s 5 GW wind target reflects a bold departure from previous plans, which heavily emphasized coal expansion. By rebalancing the energy mix, the government hopes to make renewable energy one-third of total generation by 2030.
At present, coal-fired power plants account for around 60 percent of Indonesia’s electricity. This heavy reliance poses challenges not only for climate commitments but also for long-term economic resilience. As demand for cleaner energy grows globally, Indonesia risks economic isolation if it fails to adjust.
The new target, however, signals intent to reverse course. It builds upon President Prabowo Subianto’s pledge to retire all fossil fuel plants within 15 years and to build 75 GW of renewables during the same period.
Unlocking JETP Financing
Indonesia’s strategy is closely tied to international funding commitments. The JETP fund, backed by the United States, Japan, and European partners, is contingent on credible renewable deployment pipelines. Wind projects are seen as critical to this pipeline, offering visible progress toward decarbonization.
Finance experts highlight that achieving bankable projects will require robust Power Purchase Agreements (PPAs), risk-sharing frameworks, and guarantees to attract global capital. Without these, the 5 GW target could remain aspirational.
Domestic Policy Shifts
The regulatory framework is evolving to support wind investment. Presidential Regulation 112/2022 established new tariff mechanisms, moving away from outdated benchmarks. This reform is designed to provide developers with clearer price signals and to reduce uncertainty.
Yet, regulatory bottlenecks remain. Licensing, local content requirements, and land acquisition issues could delay projects. Observers note that unless these barriers are streamlined, the pace of deployment may fall short of expectations.
Technical and Infrastructure Challenges
Building nearly 5 GW of wind capacity in just five years requires unprecedented speed and coordination. Indonesia must tackle logistical, infrastructural, and grid integration challenges.
Wind resources are concentrated in provinces like South Sulawesi, East Nusa Tenggara, and offshore areas around Java. Many of these sites are far from industrial hubs and major population centers, requiring long-distance transmission.
The Ministry of Energy has acknowledged the need for massive investment in transmission lines, often referred to as “green grids.” Without this backbone, even the best wind sites cannot deliver power reliably to demand centers.
Land and Logistics Barriers
Onshore projects require significant land use, even if turbines occupy only a fraction of it. Negotiations with local communities can slow timelines, particularly in regions where land rights are complex.
In addition, Indonesia’s archipelagic geography complicates logistics. Transporting large turbine blades and towers demands specialized infrastructure such as reinforced roads and upgraded ports. Without such upgrades, project costs could balloon.
Integration and Grid Stability
Wind power is variable, and Indonesia’s grid must adapt to handle fluctuating generation. Grid operators are studying ways to enhance flexibility, including battery storage, demand response systems, and advanced forecasting tools.
If these technologies are not deployed in parallel, curtailment risks will rise, undermining project economics. Analysts stress that integrating 5 GW of wind requires as much focus on the grid as on the turbines themselves.
Economic and Climate Implications
The addition of 5 GW of wind capacity could generate around 13.1 terawatt hours of electricity annually, assuming a 30 percent capacity factor. This output would cover over four percent of Indonesia’s total current demand.
Economically, the plan opens new opportunities for domestic industries. Local fabrication of towers, maintenance services, and supply chain development could generate thousands of jobs. At the same time, foreign developers and investors will bring technology transfer and international expertise.
Climate-wise, wind deployment represents a major step toward Indonesia’s net-zero commitments. Replacing coal-fired electricity with wind could cut millions of tons of carbon dioxide annually, aligning with the government’s pledge to reach net zero by 2050, or sooner.
Industry Perspectives
Industry leaders view the wind target as both a challenge and an opportunity. Developers such as Vena Energy, which already operates projects in Indonesia, are preparing to expand portfolios. International turbine manufacturers see potential to localize production if project pipelines are steady.
Environmental groups, however, caution against overpromising. They note that previous renewable targets were missed due to inconsistent policy enforcement. To build credibility, the government must demonstrate steady project execution.
Public and Global Reactions
Public opinion within Indonesia is increasingly supportive of renewable energy, especially as climate awareness grows. International observers, meanwhile, regard the 5 GW target as a litmus test for Indonesia’s seriousness about energy transition.
Global markets are watching closely. Success could establish Indonesia as a renewable leader in Southeast Asia. Failure could reinforce perceptions of dependence on coal, undermining investor confidence.
In conclusion, Indonesia’s plan to install 5 GW of wind power by 2030 is bold, complex, and fraught with challenges. Yet it represents a pivotal moment in the nation’s energy trajectory. If backed by sound policies, strong financing, and effective execution, the target could transform Indonesia’s energy landscape.
