Chenab–Beas Link Tunnel Project Approved in Himachal Pradesh

By Published

In May 2026, the Government of India approved the Chenab–Beas Link Tunnel project in Himachal Pradesh with an estimated cost of ₹2,352 crore. The project involves constructing an 8.7-kilometre tunnel to divert surplus water from the Chenab basin (part of the Indus river system) into the Beas river system. Managed by the National Hydroelectric Power Corporation (NHPC), the project aims to enhance hydropower generation capacity by nearly 4,000 MW. Phase 1 includes building a 19-metre-high barrage on the Chandra river near Koksar village, a tributary of the Chenab in the western Himalayas. The project aligns with India's decision to place the Indus Waters Treaty with Pakistan in abeyance in April 2025. While an unofficial completion target of July 2029 has been mentioned, official sources have not confirmed this date.

Background & Context

The Chenab river is one of the western rivers of the Indus river system, over which India has limited usage rights under the 1960 Indus Waters Treaty with Pakistan. The Beas river is a tributary of the Sutlej river and flows through Himachal Pradesh and Punjab. River-linking projects like this aim to optimize water utilization by transferring surplus water from one river basin to another to augment irrigation, water supply, and hydropower generation. Phase 1's barrage on the Chandra river represents an integral part of this project, with the Chandra river itself being a tributary that contributes to the Chenab basin in the western Himalayas. India's suspension of the Indus Waters Treaty reflects increasing geopolitical tensions and assertive water resource management policies.

Why This Matters for Exams / Exam Relevance

This project holds significance for Indian geography and polity topics in competitive exams. It highlights the intricacies of river systems, inter-basin water transfers, and their governance, including international treaties like the Indus Waters Treaty. Understanding the role of central public sector enterprises like NHPC in infrastructure development, especially hydroelectric power, is critical. The project also illustrates India’s approach to managing transboundary water resources under geopolitical stress, a commonly tested area in current affairs and environment-related syllabus sections.

Points to Remember

  • The Chenab–Beas Link Tunnel is approved since May 2026 in Himachal Pradesh at an estimated cost of ₹2,352 crore.
