Indonesia's Power Capacity Reaches 107 GW Amid Renewable Energy Challenges

Current Energy Mix

Indonesia's total installed power capacity has reached 107 gigawatts (GW) as of October 2025, according to the Ministry of Energy and Mineral Resources (ESDM) ¹

. Despite efforts to increase the share of renewable energy, the current renewable energy mix stands at only 14.4% of the total capacity. The renewable energy sector is primarily dominated by hydropower, which accounts for 7.1% of the total capacity. Other renewable sources include biomass (3%), geothermal energy (2.6%), solar power (1.3%), wind energy (0.1%), and other renewable sources (0.3%) ¹

Challenges to Renewable Energy Adoption

The Center of Economic and Law Studies (Celios) has raised concerns about the development of new coal-fired power plants, revealing that there are 21 new captive coal-fired power plants currently in the pre-construction phase across various industrial areas in Indonesia ²

. These new coal plants are seen as a significant obstacle to achieving a higher renewable energy mix in the country's energy portfolio. The continued development of coal-fired power capacity is likely to make it challenging for Indonesia to meet its renewable energy targets.

Implications for Indonesia's Energy Future

The current energy mix and the ongoing development of coal-fired power plants indicate that Indonesia faces significant challenges in transitioning to a more sustainable energy future. While the government has set ambitious renewable energy targets, the reality on the ground suggests that coal remains a dominant force in the energy sector. The development of new coal-fired power capacity, particularly captive plants for industrial use, complicates efforts to reduce the carbon footprint and increase the share of renewable energy in the national energy mix.
