100 GW Solar Power Target: Execution Foundation Critical for Success
The government’s ambition to build 100 gigawatts (GW) of solar power plants by 2029 depends not only on the target’s scale but also on establishing a strong implementation foundation to ensure the programme progresses swiftly, measurably, and sustainably. Part of the national energy transition agenda toward energy independence, the initiative is expected to strengthen Indonesia’s position in ASEAN’s clean energy development. President Prabowo Subianto reiterated the target during the opening of the 48th ASEAN Summit in Cebu, Philippines, on 8 May.
Fabby Tumiwa, Chief Executive Officer of the Institute for Essential Services Reform (IESR), stated: “The success of the 100 GW solar programme depends not only on the target capacity but also on the government’s ability to build a foundation for rapid, measurable, and replicable implementation,” according to a statement cited on 30 May 2026.
Under the scheme, the government aims to construct 80 GW of distributed solar power and 20 GW of centralised solar power to support the net zero emissions (NZE) target by 2060 or earlier. The plan was reinforced in March 2026 as part of strategies to address the energy crisis and reduce petroleum imports in the short to medium term.
IESR has identified three priority agendas: accelerating dedieselisation, speeding up rooftop solar and Battery Energy Storage System (BESS) deployment, and developing village solar management models through Village Cooperatives or Village-Owned Enterprises (BUMDes). Among these, dedieselisation is considered the most strategic entry point. According to the 2025-2034 Electricity Supply Business Plan (RUPTL), PLN has identified approximately 3,996 diesel generators across 1,234 remote locations, targeting an 80% reduction in electricity supply from diesel power plants (PLTD) by 2030.
IESR suggests reviewing project procurement mechanisms to make them more attractive for developers and align with on-ground conditions. Additionally, fuel savings opportunities can be achieved through a fat burning programme, utilising solar power and BESS to reduce diesel consumption in existing power plants.
