Indonesia’s total renewable power capacity is projected to reach 38.1 GW by 2035, according to a new GlobalData analysis. The projection represents significant growth from the estimated 8.4 GW of installed renewable capacity in 2024, driven primarily by expanding solar PV and onshore wind development supported by national energy policies and updated investment frameworks.
The analysis indicates that solar capacity is expected to increase from 0.9 GW in 2024 to 23.2 GW by 2035, supported by floating and utility-scale solar projects, rooftop solar programmes, and policy measures such as feed-in mechanisms and updated net-metering regulations. Onshore wind capacity is forecast to grow from 0.15 GW to 2.6 GW, supported by competitive tenders and hybrid renewable developments in Sulawesi and East Nusa Tenggara. Geothermal capacity is projected to rise from 2.6 GW to 5.5 GW, backed by fiscal support through the PT SMI Geothermal Fund.
Despite strong renewable growth, Indonesia is expected to remain reliant on thermal generation through 2035. Coal-fired capacity is projected to increase from 55.6 GW in 2024 to 61.4 GW due to existing contracts and domestic reserves. Gas-fired capacity will also expand from 29.1 GW to 36 GW to provide grid stability and flexibility as renewable penetration rises.
