Shri V. L. Kantha Rao, Secretary of the Department of Water Resources, led an Indian delegation to Bhutan from 24-27 February 2026 to enhance cooperation on trans-boundary rivers and review the Punatsangchhu hydropower projects. During their bilateral meeting on 25 February, bharat and Bhutan discussed flood management, hydro-meteorological networks, and challenges related to climate change. The delegation inspected the under-construction Punatsangchhu-I Hydroelectric Project and the operational Punatsangchhu-II Project, along with other water management facilities. The visit reinforced India’s commitment to sustainable.
River Management Recently, Both
River basin management and bolstered cooperation in water resources and hydropower development bharat and Bhutan share one of the most stable and cooperative partnerships in South Asia, especially in the area of hydropower development and river management. Recently, both countries held discussions to review cooperation on trans-boundary rivers and the progress of major hydropower projects in Bhutan, particularly the projects located on the Punatsangchhu River. These discussions highlight how water resources have become a central pillar of the strategic partnership between bharat and Bhutan, strengthening economic integration, clean energy generation, and regional stability.
The Himalayan river systems flowing from Bhutan into bharat play a critical role in hydropower generation, irrigation, and ecological balance. These rivers form part of the larger basin of the Brahmaputra River, one of the most important river systems in South Asia. Because these rivers cross international boundaries, cooperation between the two countries is essential to ensure sustainable development and disaster preparedness. Through joint meetings and technical consultations, both nations have emphasized improving river basin management, expanding hydropower capacity, and strengthening flood forecasting systems Hydropower cooperation between bharat and Bhutan dates.
Technical Expertise And Financial Capacity
Back several decades and is often cited as a successful model of cross-border energy partnership. Bhutan possesses vast hydropower potential due to its mountainous terrain and fast-flowing rivers, while bharat has the technical expertise and financial capacity to support large infrastructure projects. Under this mutually beneficial arrangement, India helps finance and build hydropower projects in Bhutan, and the electricity generated is exported to India after meeting Bhutan’s domestic needs. This model has significantly boosted Bhutan’s economy while also contributing to India’s renewable energy supply Among the most prominent projects discussed during.
The recent consultations are the Punatsangchhu-I and Punatsangchhu-II hydroelectric projects. These projects are located in Bhutan’s Wangdue Phodrang district and are built on the Punatsangchhu River, which is a tributary of the Sankosh River. The Punatsangchhu basin has long been identified as a major hydropower zone capable of generating thousands of megawatts of electricity. The two large projects under development in this basin are considered milestones in bharat -Bhutan energy cooperation The Punatsangchhu-II Hydroelectric Project, with an installed capacity of about 1,020 MW, represents one of the largest hydropower plants developed through bilateral collaboration.
Project Has Been Developed With Financial
It is designed as a run-of-the-river project, meaning it uses the natural flow of the river rather than relying on a large reservoir This approach reduces environmental impact and displacement while still generating substantial amounts of electricity. The project has been developed with financial assistance from bharat and technical support from Indian engineering agencies. After years of construction and overcoming geological challenges, the project has now been commissioned and connected to Bhutan’s power grid, significantly boosting the country’s energy generation capacity The completion of the Punatsangchhu-II project has increased Bhutan’s hydropower capacity.
By a significant margin and strengthened energy trade between the two countries. Bhutan exports surplus electricity to bharat under long-term agreements, providing a major source of revenue for the Bhutanese economy. At the same time, India benefits from access to clean and renewable energy that supports its climate goals and energy security strategy. This mutually beneficial energy trade has made hydropower the backbone of bilateral economic cooperation Alongside Punatsangchhu-II, the Punatsangchhu-I Hydroelectric Project is also progressing, although the project has experienced delays due to geological challenges in the Himalayan terrain.
Grants And Concessional Loans For Construction
Once completed, this project is expected to generate around 1,200 MW of electricity, making it one of the largest hydropower facilities in Bhutan. The project is funded under an inter-governmental agreement where bharat provides both grants and concessional loans for construction. The two countries continue to coordinate closely to ensure the timely completion of this strategic project Beyond these projects, the bharat Bhutan hydropower partnership includes several other successful initiatives. Projects such as Chukha, Tala, Kurichhu, and Mangdechhu have already been commissioned and contribute significantly to Bhutan’s power generation capacity.
These projects have demonstrated how regional cooperation can promote sustainable development while addressing growing energy demands. Together, these hydropower plants produce thousands of megawatts of electricity, much of which is exported to bharat Another important aspect of bharat –Bhutan cooperation involves managing trans-boundary rivers through improved hydro-meteorological monitoring. The Himalayan region is prone to extreme weather events, glacial lake outburst floods, and seasonal flooding during the monsoon. To address these risks, India has helped Bhutan establish a network of monitoring stations that track rainfall, river discharge, and water levels.
Several Rivers Flowing From Bhutan Into bharat
These systems provide real-time data that help authorities in downstream bharat states prepare for floods and other natural disasters. Such early warning systems play a crucial role in protecting communities and infrastructure in the region Several rivers flowing from Bhutan (bharat) into bharat are classified as trans-boundary rivers because they cross international borders before joining larger river systems. These include rivers such as the Manas River, Raidak River, and Amo Chhu. These rivers eventually feed into the Brahmaputra basin and support millions of people across northeastern bharat and Bangladesh. Effective management of these rivers requires close coordination.
Between upstream and downstream countries to balance energy development, environmental protection, and water security In addition to technical cooperation, hydropower collaboration also strengthens diplomatic relations between India and Bhutan. The two countries share a special relationship based on mutual trust, cultural ties, and strategic cooperation. Bhutan’s hydropower sector has grown largely through bharat investment and support, making India the largest market for Bhutanese electricity exports. This relationship helps Bhutan maintain economic stability while enabling India to diversify its renewable energy portfolio.
Both India And Bhutan Have Committed
Hydropower projects also play a key role in promoting sustainable development in the Himalayan region. Because these projects rely on renewable water resources, they contribute to reducing carbon emissions and supporting global climate goals. Both India and Bhutan have committed to expanding renewable energy capacity as part of their climate action strategies. By investing in large hydropower projects and strengthening river basin cooperation, the two countries are demonstrating how regional partnerships can accelerate the transition to clean energy The discussions on trans-boundary river cooperation also reflect the broader vision of regional connectivity and environmental resilience.
As climate change continues to affect glacier melt and river flows in the Himalayas, coordinated water management has become increasingly important. Joint studies, data sharing, and infrastructure planning will help both countries adapt to changing hydrological patterns (India) and protect vulnerable communities The recent review of trans-boundary river cooperation and the progress of the Punatsangchhu hydropower projects highlights the depth of the India–Bhutan partnership.
Through collaborative efforts in hydropower development, flood management, and environmental monitoring, both countries are building a sustainable model of regional cooperation. The Punatsangchhu projects stand as powerful symbols of this partnership, demonstrating how shared natural resources can be harnessed for mutual prosperity, clean energy generation, and long-term economic growth in South Asia.
