Supporting the Energy Transition with a Sovereign Green Fund
The global energy transition has moved far beyond academic debates. The world is now entering a phase of intense geo-economic competition, where nations race to secure clean energy technologies, investments, and supply chains.
In this context, the target of developing 100 GW of solar power plants announced by President Prabowo Subianto is not merely a commitment to emissions reduction. It is a strategic signal that Indonesia aims to become a major player in the future energy economy.
However, behind this grand ambition lies a fundamental challenge that will determine its success: financing. A project of this scale requires enormous investment, while relying on the conventional State Revenue and Expenditure Budget is neither realistic nor sustainable.
Indonesia’s current fiscal space must accommodate various development priorities, from food security and health to education. If the energy transition financing is entirely burdened on the state budget, the risk of deficits will increase, and macroeconomic stability could be disrupted.
On the other hand, dependence on foreign debt or high-risk commercial financing instruments will open new vulnerabilities, particularly to exchange rate fluctuations and external pressures. In such a situation, Indonesia needs a more strategic approach. The energy transition cannot just be financed; it must be capitalised.
The answer to this challenge lies in establishing a Sovereign Green Fund, a sovereign fund specifically designed to finance clean energy infrastructure sustainably. This fund is not merely an investment vehicle but a fiscal engineering instrument capable of converting conventional energy wealth into the foundation for future energy.
The primary sources of funding for this fund could come from windfall tax mechanisms on the fossil fuel sector, particularly the coal industry. For over two decades, this sector has made significant contributions to state revenues, especially when commodity prices surge. However, at the same time, these activities have generated significant externalities, from environmental pressures to social costs.
The implementation of a windfall tax is not intended to weaken the industry but to correct this imbalance. A portion of the extraordinary profits generated today needs to be redirected to finance the energy transition. In this way, wealth derived from fossil fuels does not end as short-term consumption but becomes a long-term investment for future generations.
To be effective, the Sovereign Green Fund must be designed with strict governance principles. This fund needs to be clearly separated from the general state budget and protected by a strong legal framework. Its use should focus on three main priorities: initial financing for large-scale solar energy projects, strengthening modern electricity grid infrastructure, and providing risk guarantee instruments to attract private investment.
The presence of this fund will have a significant impact on the energy market structure. Long-term funding certainty will reduce investment risks, ultimately lowering the cost of capital. With lower capital costs, the price of electricity from solar energy can become more competitive and affordable for the public. This is the key to ensuring the energy transition does not burden purchasing power.
Moreover, the Sovereign Green Fund can also serve as a tool to strengthen domestic industrialisation. With guarantees for large and sustainable projects, Indonesia has leverage to encourage technology transfer and increased domestic content. Investors will not only come to build power plants but also to establish manufacturing facilities for solar panels, batteries, and other supporting components.
With this approach, the energy transition will not only produce clean electricity but also create new high-value-added industrial clusters. This strategy needs to go hand in hand with energy subsidy reforms.
For years, fuel and electricity subsidies have contained inefficiencies that burden the state budget. Transforming towards more targeted subsidies will open up additional fiscal space. These savings can be redirected as capital to strengthen the Sovereign Green Fund, creating a sustainable financing cycle.
The synergy between windfall taxes and subsidy reforms will form an independent foundation for transition financing. Indonesia does not need to fully rely on external financing that often comes with conditions limiting national policy space.
In the geopolitical context, this approach has high strategic value. Many global green financing schemes offer support, but they often come with hidden interests. Dependence on external funding sources can reduce policy flexibility and limit the direction of national industrialisation.
With a strong Sovereign Green Fund, Indonesia has autonomy to determine its own transition direction. The country can choose appropriate technologies, develop domestic supply chains, and protect national industry interests without external pressures.
Ultimately, the 100 GW solar energy project is not just an energy project but has the potential to become an economic transformation project. Its success is not only determined by installed capacity but by the country’s ability to build a strong and sustainable financing system.
The Sovereign Green Fund offers the most rational and strategic way forward. It is now time for the government to take firm steps to build an independent and sovereign financing architecture.
With a transparent, disciplined design oriented towards the long term, Indonesia can…
