The Government of Indonesia has announced plans to develop 100 GW of solar power capacity before 2029 as part of its broader strategy to expand renewable energy generation, strengthen energy security and support long-term decarbonisation objectives. The programme targets the deployment of 80 GW of distributed solar capacity and 20 GW of utility-scale solar projects across the country.
The initiative forms a key component of Indonesia’s goal of achieving a fully renewable energy-based power system by 2035 and reaching net-zero emissions by 2060 or earlier. The Institute for Essential Services Reform (IESR) has highlighted several priority areas to support implementation, including accelerating the replacement of diesel-powered generation, particularly in remote and island communities. State-owned utility PLN aims to reduce diesel-based electricity generation by 80 per cent by 2030 through greater integration of solar power and battery energy storage systems. IESR has also recommended packaging smaller renewable energy projects into larger investment opportunities to attract private sector participation.
Additional recommendations include expanding rooftop solar adoption through enhanced financial incentives and increasing the deployment of battery energy storage systems to improve grid flexibility and renewable energy integration. IESR has also proposed establishing a national solar task force and developing a dedicated five-year implementation roadmap to coordinate project delivery, improve policy execution and support the long-term growth of Indonesia’s renewable energy sector.
