The Dorjilung Hydropower Project is a planned 1,125 MW run-of-river hydroelectric project on the Kurichhu River in Mongar district, Bhutan. Jointly owned by Druk Green Power Corporation (60%) and Tata Power (40%), it is the largest public-private partnership hydropower project in Bhutan's history.
The Dorjilung Hydropower Project is a planned 1,125 megawatt (MW) run-of-river hydroelectric power project being developed on the Kurichhu River in Mongar district, eastern Bhutan. The project is being implemented by Dorjilung Hydro Power Limited (DHPL), a special purpose vehicle jointly owned by Bhutan's Druk Green Power Corporation (DGPC) holding 60 percent and India's Tata Power holding 40 percent. At a total estimated project cost of approximately INR 13,100 crore (roughly USD 1.5 billion), it is the largest public-private partnership (PPP) hydropower project ever undertaken in Bhutan and is expected to be the country's second-largest hydropower facility upon completion.[1]
Project Specifications
The Dorjilung project is designed as a run-of-river scheme with six generating units of 187.5 MW each, for a total installed capacity of 1,125 MW. The project includes a six-hour pondage facility for peaking power generation, allowing it to store water and release it during periods of peak electricity demand rather than generating power at a constant rate. It is expected to generate more than 4,500 gigawatt-hours (GWh) of clean electricity annually.[2]
The project is located on the Kurichhu (also spelled Kuri Chhu), one of the major rivers of eastern Bhutan. Bhutan already operates the 60 MW Kurichhu Hydropower Plant on the same river, which was commissioned in 2002 with Indian assistance.
Ownership and Partnership Structure
The project represents a significant evolution in Bhutan's approach to hydropower development. While Bhutan's earlier large hydropower projects, such as the Chukha (336 MW), Tala (1,020 MW), and Mangdechhu (720 MW) plants, were developed as intergovernmental projects between Bhutan and India, Dorjilung is structured as a public-private partnership. DGPC, which is wholly owned by the Royal Government of Bhutan, holds the majority 60 percent stake, while Tata Power, India's largest private integrated power company, holds 40 percent. Tata Power has committed an equity investment of approximately INR 1,572 crore.[3]
World Bank Financing
In January 2026, the Board of Executive Directors of the World Bank Group approved a comprehensive financing package for the Dorjilung project. The package includes:
- USD 150 million grant from the International Development Association (IDA)
- USD 150 million credit from IDA
- USD 15 million enclave loan from the International Bank for Reconstruction and Development (IBRD) to DGPC
- USD 200 million IBRD enclave loan to DHPL
- USD 300 million loan from the International Finance Corporation (IFC) to DHPL
The total World Bank Group financing of approximately USD 815 million is expected to mobilize an additional USD 900 million from private investors, bringing the total financing to over USD 1.7 billion.[2]
Timeline and Power Export
The project is scheduled for commissioning in September 2031. Upon completion, approximately 80 percent of the electricity generated will be exported to India under long-term power purchase agreements, consistent with the framework governing Bhutan-India hydropower cooperation. The project is expected to expand Bhutan's installed energy capacity by nearly 40 percent.[1]
Strategic Significance
Hydropower is Bhutan's most significant natural resource and the backbone of its export economy. Revenue from hydropower exports to India constitutes a major share of government revenue and has been central to Bhutan's development strategy since the commissioning of the Chukha plant in 1986. The Dorjilung project is part of a broader effort to develop Bhutan's estimated 30,000 MW of hydropower potential, of which only a fraction has been harnessed to date.
The PPP model used for Dorjilung is being closely watched as a potential template for future hydropower development in Bhutan. Earlier intergovernmental projects, while successful, involved significant sovereign debt to India. The involvement of private capital and multilateral financing institutions in Dorjilung diversifies Bhutan's financing sources and introduces a different risk-sharing structure.
The project also aligns with Bhutan's positioning as a net exporter of clean energy. Bhutan is one of the few countries in the world that is carbon negative, absorbing more carbon dioxide through its forests than it emits. Hydropower exports are central to maintaining this status while generating the revenue needed for the country's continued development.

Punatsangchhu-I Hydropower Project
The Punatsangchhu-I Hydroelectric Project (PHPA-I) is a 1,200 MW run-of-the-river hydropower scheme under construction on the Punatsangchhu river in Wangdue Phodrang dzongkhag. Launched in 2008 with an original commissioning target of 2015, it has been severely delayed by recurrent slope instability on the right bank above the dam, with cost estimates rising from around Nu 35 billion to over Nu 90 billion.

The Punatsangchhu-II Hydroelectric Project (PHPA-II) is a 1,020 MW run-of-the-river hydropower scheme on the Punatsangchhu river in Wangdue Phodrang dzongkhag, downstream of Punatsangchhu-I. Launched in 2010 and originally targeted for completion in 2018, its first units were synchronised in December 2024, with the final unit connected to the grid in August 2025.

The 2,640 MW Kuri-Gongri Hydropower Project is a planned reservoir-based hydropower scheme on the Kuri Chhu and Gongri Chhu in eastern Bhutan, currently in extended planning. Originally conceived in the 2008 India–Bhutan agreement to develop 10,000 MW by 2020, the project has been redesigned from run-of-river to reservoir, with the most recent Detailed Project Report estimating capital costs of approximately Nu 306–307 billion. As of mid-2025 no construction agreement has been signed.

The Punatsangchhu Hydroelectric Project comprises two large run-of-river hydropower plants on the Punatsangchhu (Sunkosh River) in Wangdue Phodrang District, Bhutan: Punatsangchhu-I (1,200 MW, still under construction) and Punatsangchhu-II (1,020 MW, fully commissioned August 2025 and inaugurated November 2025). Originally expected online by 2016-2017, both projects suffered severe delays and massive cost overruns. Punatsangchhu-II was commissioned in phases from December 2024 to August 2025, boosting Bhutan's power generation capacity by 40%, while Punatsangchhu-I remains stalled by geological challenges.
