Report Launching on Solar Archipelago: Delivering 100 GW Solar PV Program in Indonesia In Collaboration IESR and the Coordinating Ministry for Economic Affairs (CMEA)
Background
The Ministry of Energy and Mineral Resources (KESDM) has published the National Electricity General Plan (RUKN) for the 2025-2060 period. The RUKN document states that to achieve the NZE by 2060 or earlier, an average annual increase in power generation of approximately 9.6 GW is required to reach a total capacity of 443 GW connected to the national power system. Of this 443 GW, approximately 41.5% will come from variable renewable energy (VRE) generation, complemented by 34 GW of energy storage, and 58.5% from dispatchable (non-VRE) generation. Based on the share of VRE generation, solar power plants (PLTS) will become the backbone of the national power system in 2060, with a total capacity of approximately 108.7 GW, followed by wind power plants (73.5 GW) and hydro power plants (70.5 GW).
Meanwhile, PLN’s RUPTL (Regional Electricity and Power Plant) for the 2025-2034 period demonstrates planning in line with the RUKN (National Development Plan) for 2025-2060. The plan includes a 42.6 GW capacity increase from renewable energy, with the largest increase coming from solar power plants (PLTS), at 17.1 GW. This requires PLN to successfully procure renewable energy plants to commercial operation (COD), at an average annual rate of 4.26 GW. Meanwhile, the average increase in renewable energy generating capacity on PLN’s grid over the past five years has only been 0.7 GW (IESR, 2025).
Furthermore, to realize one of the Astacita missions, namely energy self-sufficiency, President Prabowo ordered the construction of 100 GW of solar power plants equipped with 320 GWh of energy storage systems, spread across 80,000 villages across Indonesia (Kompas, 2025). The policy aimed at expanding electricity access to all villages in Indonesia, managed by each of the 80,000 Red and White Village Cooperatives (KDMP), deserves to be welcomed and supported with a comprehensive strategy and planning. This policy will undoubtedly address the challenges faced by the Indonesian government in increasing electrification in villages that do not yet receive electricity from PLN, which number approximately 5,758 villages or 1.2 million households (ESDM, 2025). Therefore, solid collaboration between various stakeholders across sectors at various levels is necessary to ensure the successful implementation of the 100 GW solar power plant (PLTS) development program, provide benefits to the community, and ensure sustainability.
The IESR commends President Prabowo’s initiative to develop 100 GW of solar power plants. This program can accelerate the energy transition, encourage the growth of the solar energy technology supply chain, create green jobs, and increase access to quality, equitable, and affordable electricity, while supporting efforts to achieve national energy independence and self-sufficiency. In line with the urgency and scale of the program, IESR, in collaboration with the Ministry of Economic Affairs, has prepared an initial report on the roadmap for implementing the 100 GW solar PV program. This initial report is planned to be officially launched to the public and stakeholders through the Initial Report Launching on Solar Archipelago: Delivering 100 GW Solar PV Program in Indonesia.
Objective
- Disseminate the IESR’s initial report on the proposed implementation of the 100 GW Solar Power Plant (PLTS) program.
- Discuss recommendations for the implementation of the 100 GW Solar Power Plant (PLTS) program.
