Wangchhu Hydroelectric Project
Why in news?
The Wangchhu Hydroelectric Project is a 570 MW run-of-the-river hydropower initiative on the Wangchhu River in Bhutan's Chukha District. Adani Group officially commenced construction in early January 2026, following an initial announcement in September 2025.
Key Highlights of the Wangchhu Project
- Capacity: 570 MW hydropower generation.
- Location: Bhutan, on the Wangchhu river.
- Partnership: Adani Group (India) and Druk Green Power Corporation (Bhutan).
- Investment: Approx. $666 million (₹60 billion).
- Model: BOOT (Build, Own, Operate, Transfer).
- Purpose: Designed as a peaking run-of-river scheme, meaning it will generate electricity during peak demand hours without requiring massive reservoirs.
- Timeline: Agreements signed in September 2025; foundation stone laid soon after; construction commenced in early 2026.
- Strategic Goal: Part of a broader India–Bhutan partnership to develop 5 GW of hydropower capacity in Bhutan.
Significance
- Energy Security for Bhutan: Hydropower is Bhutan’s largest export and revenue source. Wangchhu adds substantial capacity to its grid.
- Regional Cooperation: Strengthens India–Bhutan energy ties, with India expected to be a major buyer of generated electricity.
- Sustainability: Run-of-river design reduces ecological disruption compared to large dam projects, though seasonal river flow variability remains a challenge.
- Economic Impact: The $666M investment boosts local employment, infrastructure, and long-term energy trade revenues.
