| 1 | PLN Transmission Network Expansion Programme (RUPTL 2025–2034) | Nationwide, including intra-island and inter-island systems | PLN’s national transmission expansion plan calls for 47,758 circuit-kilometres (ckm) of additional transmission network and 107,950 MVA of new substation capacity. It is designed to connect renewable-energy zones, industrial demand, and more integrated island power systems. Estimated transmission and substation investment: IDR392.1 trillion (about USD24.4 billion). | PT PLN (Persero), Indonesia’s state electricity company. PLN is a state-owned enterprise whose asset-management oversight is linked to Danantara. | 2025 | Planned / implementation phase under the current RUPTL | 2034 | IEEFA |
| 2 | Indonesia Super Grid / National Interconnection Programme | Nationwide; intended to link major island systems, notably Sumatra, Java, Kalimantan, Sulawesi, and eastern Indonesia | A strategic grid-modernisation and interconnection programme embedded in national electricity planning. Its purpose is to increase transfer capacity between supply and demand centres, enable large-scale renewables, reduce congestion, and support potential ASEAN regional electricity trade. Publicly available materials describe it primarily as a programme/pipeline, rather than a fully disclosed list of individual transmission contracts. | PLN as the grid owner/operator and implementing utility; Government of Indonesia provides planning and regulatory direction. Danantara is relevant as the state investment/asset-management platform overseeing PLN-related state assets, but no specific project investment vehicle was identified. | 2025 planning period | Planned / pipeline | Long-term; aligned with national planning to 2060, with RUPTL-linked investments through 2034 | IEEFA |
| 3 | Sustainable Energy Access in Eastern Indonesia – Electricity Grid Development Program, Phase 2 | Nine provinces: West Kalimantan, South Kalimantan, Central Kalimantan, East Kalimantan, North Kalimantan, Maluku, North Maluku, Papua, and West Papua | An ADB-supported PLN grid-development programme focused on expanding and strengthening medium-voltage distribution networks and improving access, reliability, renewable-energy use, and PLN operational systems. While it is primarily distribution rather than high-voltage transmission, it is directly related to grid expansion and state-owned PLN infrastructure. The programme targeted at least 63,692 ckm of cumulative MV-line installation by 2024; PLN reported 64,999 ckm as of Q4 2024. | PT PLN (Persero); financing support from the Asian Development Bank (ADB) through a USD600 million results-based loan. | January 2020 | Under implementation; the 2024 MV-network target was achieved, while the renewable-generation output target remained below target at end-2024 | Programme completion: 31 December 2025; loan closing: 30 June 2026 | ADB |
| 4 | South Sumatra–Lampung Strengthening and Rantau Dedap Geothermal Evacuation Project | South Sumatra and Lampung | Transmission and substation reinforcement programme that both strengthens the South Sumatra–Lampung grid and evacuates output from the Rantau Dedap geothermal power plant. It is particularly relevant to the energy transition because transmission infrastructure is required to bring geothermal generation to load centres. | PT PLN (Persero); implemented through the relevant PLN transmission/substation project unit in southern Sumatra. | 8 August 2020 | Under implementation in the cited PLN report; the report frames the project as supporting delivery of lower-cost electricity and geothermal evacuation. | 1 December 2025 | Ruang Energi |
| 5 | Java–Bali 500 kV Power Transmission Crossing Project | Java–Bali interconnection | A 500 kV transmission-crossing project intended to reinforce the Java–Bali electricity connection. It is a major historic PLN transmission project; ADB’s country-programme review lists it as closed. | PT PLN (Persero), with ADB financing support. | 3 December 2013 | Closed / completed in ADB portfolio reporting | Closed | ADB |
| 6 | Paiton–Kediri–Klaten 500 kV Transmission Component | East and Central Java | Construction of approximately 415 km of double-circuit 500 kV overhead transmission lines connecting Paiton–Kediri and Kediri–Klaten. The project was intended to reinforce Java’s extra-high-voltage backbone and enable delivery of generation across the system. | PLN / Government of Indonesia; supported by the World Bank under a PLN power-sector project. | – | – | – | World Bank |
