Recent Development
Punatsangchhu II Hydroelectric Project Agreement: India and Bhutan recently signed the Tariff Protocol for the Punatsangchhu-II Hydroelectric Project, marking a significant step in bilateral energy cooperation. This agreement finalizes the electricity pricing mechanism and strengthens long-term energy trade between the two countries.
The project reflects the strong strategic and economic ties between India and Bhutan, especially in the hydropower sector. Bhutan exports surplus electricity to India, which forms a key part of its economy.
Static GK fact: Bhutan is known as the “Land of Thunder Dragon” and has one of the highest hydropower potentials in South Asia.
About the Hydroelectric Project
The Punatsangchhu-II project is a 1020 MW run-of-the-river hydropower project located in Bhutan. It is designed to generate electricity without large-scale water storage, making it environmentally sustainable.
The project is part of a series of joint hydroelectric initiatives between India and Bhutan. It follows the earlier Punatsangchhu-I project, contributing to Bhutan’s goal of becoming a major clean energy exporter.
Static GK Tip: Run-of-the-river projects use natural river flow and have minimal reservoir storage compared to dam-based projects.
River System and Geography
The Punatsangchhu River is formed by the confluence of two major rivers, Phochhu and Mochhu, in Bhutan. These rivers originate in the Himalayan region and carry glacial meltwater.
After formation, the river flows southward into the Indian plains of West Bengal. It eventually joins the Brahmaputra River, one of the largest river systems in Asia.
Static GK fact: The Brahmaputra originates from the Angsi Glacier in Tibet, where it is known as the Yarlung Tsangpo.
Strategic and Economic Importance
The project strengthens India-Bhutan hydropower cooperation, which is a cornerstone of their bilateral relations. India provides financial and technical assistance, while Bhutan benefits from revenue through electricity exports.
Hydropower plays a crucial role in promoting renewable energy and reducing dependence on fossil fuels. The project also supports regional energy security and sustainable development goals.
Additionally, the Tariff Protocol ensures predictable pricing, making power trade more efficient and transparent between both nations.
Environmental and Regional Impact
As a run-of-the-river project, Punatsangchhu-II minimizes ecological disruption compared to large dams. It helps maintain river flow and reduces displacement issues.
However, like all Himalayan projects, it must address challenges such as geological instability and climate-related risks. Careful planning and monitoring are essential for long-term sustainability.
Static GK Tip: The Himalayas are considered a young fold mountain system, making the region geologically sensitive for large infrastructure projects.
