1Upper Cisokan Pumped Storage Hydropower Plant (UCPS)West Bandung and Cianjur Regencies, West Java; using the Cisokan and Cirumamis RiversA 1,040 MW pumped-storage hydropower plant with upper and lower reservoirs and associated 500 kV transmission lines. It is intended to supply peak power to the Java–Bali grid and provide flexibility for higher variable-renewable penetration.PT PLN (Persero) is the developer and implementing entity. Financing involves the World Bank and Asian Infrastructure Investment Bank. As PLN is a strategic SOE, the project is relevant to Danantara’s SOE portfolio and renewable-energy investment agenda.Project implementation formally restarted under the renewed World Bank-supported project in 2021; PLN’s current project documentation shows land acquisition for a contractor facility was completed in December 2023.Under construction / implementation. The World Bank’s current project documentation identifies UCPS civil works and transmission development as active components.2028 is the currently cited optimal commissioning date. Earlier 2024–2025 and 2016 targets are obsolete.World Bank
2Jatiluhur Pumped Storage Hydropower PlantJatiluhur / Ir. H. Djuanda Reservoir area, Purwakarta Regency, West Java; linked with the Cirata reservoir systemA proposed 760 MW pumped-storage project for the Java–Bali system. It is designed to store electricity by pumping water during lower-demand periods and generating during peak periods, improving grid flexibility for renewable generation. Indicative annual output is reported at 1,206 GWh.Project is being developed through PLN Indonesia Power (PLN IP), PLN’s power-generation subsidiary. PLN’s 2025–2034 planning characterizes it as an IPP-developed project; Perum Jasa Tirta II has also been involved in earlier development cooperation.Development cooperation between Perum Jasa Tirta II and Sinohydro was initiated through an MoU signed on 5 March 2018. PLN IP planned partner selection beginning in 2025.Development / partner-selection and procurement preparation. It is not yet reported as under physical construction.2032Jasa Tirta II
3Tanjung Sakti Hydropower PlantBorder area between South Sumatra and Bengkulu provinces; associated reporting places it in/near South Bengkulu RegencyA 94 MW reservoir-type hydropower plant intended to connect to the Sumatra grid. Reported indicative investment is US$329 million, including approximately US$230 million expected from project financing.PLN Indonesia Power is marketing/developing the project and seeking investment partners. As PLN IP is a PLN subsidiary, the plant is SOE-linked and relevant to Danantara’s PLN-related asset base.No definitive construction start date has been publicly reported. The project was presented to prospective Japanese investors in December 2024.Pre-construction / investor and project-financing solicitation.2032Global Energy Monitor
4Tabang Hydropower PlantTabang Village, Tabang District, Kutai Kartanegara Regency, East KalimantanA run-of-river hydropower project reported at 101–110 MW depending on the project document/source. It is intended to connect to the Kalimantan grid, supporting electricity demand associated with East Kalimantan development and the Nusantara Capital City area.PLN Indonesia Power is the SOE project sponsor/developer and has sought project-financing partners. It is therefore linked to PLN’s strategic asset portfolio under Danantara’s SOE-management framework.Feasibility study had been completed by December 2024; no confirmed construction-start date is publicly reported.Feasibility study completed; pre-construction / financing and partner-development stage.2031The Jakarta Post
5Sumatra Peaker Hydro Procurement Package (GIGA ONE Hydro)Sumatra; individual sites not yet publicly specifiedA PLN procurement package of approximately 1,071 MW of hydropower projects intended to support peaking needs. It is part of PLN’s “GIGA ONE Hydro” bundling approach under the 2025–2034 Electricity Supply Business Plan (RUPTL).PT PLN (Persero) is the procuring SOE. The projects are expected to be developed through procurement/IPP structures rather than necessarily being PLN-owned generation assets.Procurement had entered the tender process by August 2026; project-specific construction dates are not yet available.Tendering.Not publicly specified on a project-by-project basis.Antaranews
6Sumatra Baseload Hydro Procurement Package (GIGA ONE Hydro)Sumatra; individual sites not yet publicly specifiedA proposed 1,800 MW bundle of hydropower projects intended to provide baseload electricity under PLN’s 2025–2034 RUPTL implementation.PT PLN (Persero) is the procuring SOE; likely implementation is through IPP procurement structures. This is consequently relevant to Danantara through PLN’s pipeline, rather than through an identified Danantara direct investment.No construction start date. The package remained in feasibility-study preparation as of August 2026.Feasibility-study stage.Not publicly specified. PLN intended a phased procurement launch, beginning with roughly 350 MW.Antaranews
7Kalimantan Peaker Hydro Procurement Package (GIGA ONE Hydro)Kalimantan; individual sites not yet publicly specifiedA planned 150 MW hydropower procurement package for peaking requirements in Kalimantan.PT PLN (Persero) is the procuring SOE; prospective IPPs would develop the plants.No public construction start date. Tender documentation was being finalized as of August 2026.Tender-document preparation.Not publicly specified.Antaranews
8Kalimantan Baseload Hydro Procurement Package (GIGA ONE Hydro)Kalimantan; individual sites not yet publicly specifiedA planned 825 MW hydropower procurement package for baseload supply in Kalimantan.PT PLN (Persero) is the procuring SOE; delivery is expected through IPP procurement.No public construction start date. Tender documentation was being finalized as of August 2026.Tender-document preparation.Not publicly specified.Antaranews
9Sulawesi Baseload Hydro Phase I (GIGA ONE Hydro)Sulawesi; individual sites not yet publicly specifiedA planned 1,400 MW portfolio/package of hydropower projects for baseload generation in Sulawesi.PT PLN (Persero) is the procuring SOE; prospective IPPs are expected to participate.No public construction start date. Tender documentation was being finalized as of August 2026.Tender-document preparation.Not publicly specified.Antaranews
