The Indian government has accelerated the long-delayed 930 MW Kirthai Stage II Hydroelectric Project on the Chenab river in the Kishtwar district of Jammu and Kashmir. The administrative revival involves transferring the project’s terms of reference to Chenab Valley Power Projects Limited to fast-track ground investigations and land acquisition. This development follows a strategic shift after India suspended participation in the Indus Water Treaty (IWT) in response to the 2025 Pahalgam terror attack. The suspension cleared a decade of diplomatic deadlock, allowing India to resume multiple critical hydropower infrastructures on the Chenab river that Pakistan previously stalled with formal objections.
Project Profile and Technical Specifications
Structural Engineering Details
- Type of Project: It is a run-of-river scheme designed to utilize the natural flow of the Chenab river for electricity generation with minimal environmental disruption.
- Generation Capacity: The plant possesses an aggregate installed capacity of 930 MW, consisting of an underground powerhouse and a dam toe powerhouse.
- Dam Structure: The layout plans a 121-meter-high concrete gravity dam measuring approximately 219.80 meters in length at the top.
- Water Conveyance System: The design features a headrace tunnel measuring over 4 kilometers in length and 11 meters in diameter alongside matching pressure shafts.
- Reservoir Parameters: The structure allows a maximum live storage capacity of 17 million cubic meters (MCM) to balance daily peaking operations.
Institutional Framework
- Implementing Agency: The operational management shifted to Chenab Valley Power Projects Limited, a specialized corporate joint venture.
- Corporate Ownership: The joint venture comprises equity investments from NHPC Limited (51%), Jammu and Kashmir State Power Development Corporation (39%), and PTC India Limited (10%).
- Clearance Pipeline: The project initially secured a Terms of Reference validation from the Ministry of Environment, Forest and Climate Change in June 2013, followed by successful conditional recommendations by the Expert Appraisal Committee.
Geopolitical and Strategic Context
Indus Water Treaty Impact
The 1960 Indus Water Treaty allocates control over three eastern rivers (Ravi, Beas, Sutlej) to India, while the three western rivers (Indus, Jhelum, Chenab) are allocated to Pakistan. Under the treaty conditions, India holds limited rights to construct run-of-river installations on the western rivers without altering total volumetric flows downstream. Pakistan repeatedly used these provisions to contest the structural dimensions, turbine configurations, and pondage levels of the Kirthai project, halting its progress since its baseline conceptualization in 1984.
Security Paradigm Shift
The decision to place the Indus Water Treaty in abeyance marks a critical transition in transboundary water diplomacy. India has linked regional security directly to bilateral water sharing arrangements, opting to fully utilize its legal hydro-potential within the Chenab basin to meet domestic power demands.
Hydro-Power Potential of Chenab Basin
Cascading Hydroelectric Projects
The Chenab river basin contains massive potential energy pathways. The Kirthai Stage II project operates inside a larger cascading network of functional, under-construction, and planned energy installations.

IASPOINT Booster Facts for UPSC
- Chenab River Origin: The Chenab river forms in the Lahaul and Spiti district of Himachal Pradesh at Tandi through the confluence of two mountain streams, the Chandra and the Bhaga. In its upper courses, it is officially designated as the Chandrabhaga.
- Major Tributaries: Key right-bank tributaries include the Ans, Bhut Nalla, Bichleri, and Marusudar rivers. Left-bank tributaries include the Tawi, Neeru, and Liddrari rivers.
- Run-of-River Principle: Unlike large reservoir-based dams, run-of-river projects do not cut off the flow of a river entirely. They divert a portion of the water through a penalizing loop or tunnel to turn turbines before discharging the entire volume back into the mainstream river channel downstream.
- Permanent Indus Commission: This bilateral body was established under Article VIII of the IWT to serve as the first channel for resolving disputes over river engineering specifications before India suspended participation.
