GlobalData’s latest report, Indonesia Power Market Trends and Analysis by Capacity, Generation, Transmission, Distribution, Regulations, Key Players and Forecast to 2035, provides in-depth insights into the country’s evolving powerfulness landscape. The survey analyses installed capableness (in gigawatts, GW), procreation (in terawatt hours, TWh), exertion premix and regulatory frameworks crossed the humanities play 2020 to 2024 and the forecast play 2025 to 2035. It besides evaluates marketplace trends, concern opportunities and cardinal institution strategies. The investigation draws upon GlobalData’s proprietary databases, superior and secondary research, and adept modelling.

Indonesia is advancing its cleanable vigor modulation portion maintaining a beardown reliance connected thermal generation, supported by large investments successful star photovoltaic (PV), onshore upwind and geothermal energy. The country’s cumulative renewable powerfulness capableness is forecast to scope 38.1GW by 2035, up from 8.4GW successful 2024, registering a compound yearly maturation complaint (CAGR) of 14.7% betwixt 2024 and 2035.

Solar PV capableness is expected to surge from 0.9GW successful 2024 to 23.2GW successful 2035, driven by the enlargement of floating and utility-scale projects and rooftop star programmes nether updated feed-in and net-metering mechanisms. Onshore upwind capableness volition emergence from 0.15GW to 2.6GW, supported by competitory tenders and hybrid renewable developments successful Sulawesi and East Nusa Tenggara. Geothermal capableness volition grow steadily from 2.6GW to 5.5GW, leveraging Indonesia’s immense geothermal reserves and fiscal enactment done the PT SMI Geothermal Fund. Supportive frameworks specified arsenic the Just Energy Transition Partnership (JETP), targeting 44% renewable energy by 2030, and the RUPTL 2025–2034 program are accelerating the cleanable vigor shift. Presidential Regulation 112/2022 has further strengthened concern clarity by limiting caller ember improvement and mandating aboriginal status pathways for existing plants. Additionally, cross-island transmission enlargement and the deployment of integer grid systems are enhancing integration and reliability.

Despite robust renewable growth, Indonesia’s powerfulness premix volition stay dominated by thermal sources successful 2035. This reflects the country’s immense home ember reserves, debased procreation costs and the captious relation of earthy state successful balancing intermittent renewables and supporting baseload reliability. Coal-fired capableness is projected to emergence from 55.6GW successful 2024 to 61.4GW successful 2035, portion gas-fired capableness volition grow from 29.1GW to 36GW. For a geographically dispersed archipelago, maintaining thermal stableness ensures accordant proviso crossed isolated land grids portion renewable infrastructure continues to standard up.
