Wangchu Hydroelectric Project

Recently, the Adani Group launched the 570 MW Wangchu Hydroelectric Project in Bhutan. This project is considered an important step towards further strengthening India-Bhutan energy cooperation.

Key Facts about the Wangchu Hydroelectric Project

• Location: The project is being developed on the Wangchu River (called the Raidak River in India) in the Chukha district of Bhutan.
• River System: The Wangchu River is a major tributary of the Brahmaputra River.
• Project Type: It is a run-of-the-river hydroelectric project that generates power with minimal dependence on water storage.
• Developer Agency: The project is being developed by Wangchu Hydroelectric Power Limited (WHPL), a joint venture company.
• Joint Venture Structure: Druk Green Power Corporation Limited (DGPC), Bhutan – 51% stake (controlling partner) and Adani Power Limited (APL), India – 49% stake
  • This joint venture was formed following a shareholders' agreement in September 2025.
• Investment and Implementation Model: The total investment is approximately ₹6,000 crore and the project will be implemented on the BOO₹ (Build, Own, Operate and Transfer) model.
• Technical Features: The project will operate as a peaking run-of-river plant, helping Bhutan offset seasonal fluctuations in hydropower generation. It will have a total of four turbines.
• Estimated annual power generation: approximately 2,478.93 gigawatt-hours (GWh)

Energy Use:

• Winter: The project will help meet Bhutan's domestic power demand, when hydropower production typically decreases.
• Summer: Excess power generated will be exported to India.

Significance

• Strengthening the India-Bhutan Strategic Energy Partnership
• Promoting renewable energy and clean energy cooperation
• Strengthening the central role of the hydropower sector in Bhutan's economy
• Contributing to India's energy security and regional energy integration
