Indonesia's state electricity company (PLN) officially announced that it has prepared to launch 21 solar photovoltaic power plants (PLTS) and photovoltaic supporting energy storage system (BESS) projects, with a total installed capacity of 513 MWp, aiming to significantly reduce the consumption of imported fuel oil in the power sector. These projects are planned to be gradually put into commercial operation (COD) between 2026 and 2028. PLN's President Director stated at a hearing of the House of Representatives' Commission XII that these 21 projects can enter the execution phase within the first half of the year, with more large-scale photovoltaic and storage special programs to be added later to further reduce the use of imported fuel. This move is also consistent with PLN's strategy of accelerating clean energy transition, which can both replace high-cost energy with low-cost energy and promote a structural shift from fossil energy to new and renewable energy. To achieve this goal, PLN has also formulated a diesel unit phase-out plan, intending to shut down a total of 2,139 diesel generator sets at 741 locations across Indonesia, fundamentally reducing fuel consumption in the power industry, alleviating the country's dependence on fuel imports, and lowering the environmental and cost pressures of power production. The 21 projects announced this time cover multiple regions in Indonesia, with varying scales and commissioning schedules. Among the larger projects include: Wonogiri Gajah Mungkur Reservoir Floating Solar PV Plant in Central Java (100 MWp), Karang Kates Floating Solar PV Plant in East Java (100 MWp), Banyuwangi Solar PV + Storage Project in East Java (100 MWp), and Pagerwojo Solar PV + Storage Project in East Java (100 MWp), all planned for commissioning in 2027. East Nusa Tenggara (NTT) Province, as a key focus area for remote regions, will see several small-scale solar projects commissioned first in 2026, including Sumba 1, Alor, Lembata 1/2, Rote 1/2, etc., prioritizing electricity supply and clean energy replacement in the eastern region. In addition, corresponding solar projects are also included in the construction list for Bangka Belitung, North Maluku, Central Papua, West Java, East Java, and other areas, with some project timelines extending to 2028 to 2029. Overall, PLN is optimizing the power structure through multiple measures: large-scale promotion of solar power plant construction, supporting energy storage applications, and phasing out old diesel units, ensuring energy security while helping Indonesia achieve its goals of energy conservation, carbon reduction, and long-term sustainable energy development
