As a global leader in solar mounting systems, Longsun Green is committed to supporting the worldwide transition to clean energy. Today, we highlight key developments and opportunities in one of Southeast Asia's most promising markets-Indonesia.
Market Overview
Indonesia, the largest economy in ASEAN and the world's fourth-most populous country, continues to demonstrate strong economic resilience with a GDP growth rate of 5.03% in 2024. The country's energy sector is undergoing significant transformation, driven by rising electricity demand and national decarbonization goals.
The power market remains largely state-dominated, with PT PLN (Persero) operating as the integrated utility controlling generation, transmission, and distribution. However, independent power producers (IPPs) also play an essential role, especially in renewable energy projects. Total power generation reached approximately 343 TWh in 2024, with more than half sourced from PLN-owned power plants and the rest from IPPs.
Despite ongoing reliance on fossil fuels-particularly coal, which accounts for 39% of the energy mix-renewable capacity is expanding. Currently, Indonesia's installed renewable energy capacity stands at 15 GW.
Renewable Potential and Policy Direction
Indonesia possesses exceptional renewable resources, including solar, geothermal, and wind:
Solar irradiation ranges between 1,280–2,280 kWh/m² annually, with technical potential exceeding 500 GW.
Geothermal resources account for 40% of the world's total, with estimated reserves of 28 GW.
Wind power potential is concentrated in coastal regions such as Sumatra and East Nusa Tenggara.
The government has introduced ambitious targets, including 75 GW of new renewable capacity by 2050, with emphasis on solar (27 GW), hydro (25 GW), wind (15 GW), and geothermal (7 GW). A major focus is also placed on grid modernization, inter-island connectivity, and microgrid deployment for underserved regions.
Opportunities for Collaboration
Indonesia's archipelagic geography presents both challenges and openings for innovative energy solutions. There is growing demand for:
Hybrid solar-storage microgrids to replace diesel generators in remote islands.
Advanced grid infrastructure, including HVDC interconnections and smart grid technologies.
Floating solar and distributed generation projects in land-constrained areas.
With its expertise in solar mounting and energy infrastructure, Longsun Green is well-positioned to support Indonesian partners in deploying efficient, large-scale renewable installations.
Conclusion
Indonesia represents a strategic growth market for renewable energy investment and technology collaboration. Longsun Green looks forward to contributing to Indonesia's energy transition with high-quality, adaptable solar mounting solutions tailored to diverse geographical conditions.
