The Central Government approved the Chenab–Beas Link Tunnel Project in May 2026 in Himachal Pradesh.
The project involves an 8.7-km tunnel to divert surplus water from the Chenab basin to the Beas River system and has an estimated cost of ₹2,352 crore.
Phase I includes a 19-metre-high barrage on the Chandra River near Koksar village in the Lahaul Valley of Himachal Pradesh.
The project will be implemented by the National Hydroelectric Power Corporation (NHPC) and is expected to support about 4,000 Megawatts (MW) of additional hydropower generation.
The Chenab River is one of the western rivers of the Indus River System governed by the Indus Waters Treaty signed between India and Pakistan in 1960.
