What Happened
- The Government of India has stated that the suspension of the Indus Waters Treaty (IWT) with Pakistan is accelerating hydropower development in Jammu & Kashmir.
- J&K's hydropower capacity is projected to rise by 46% as stalled and new projects gain clearances and faster approvals.
- Multiple projects previously constrained by IWT provisions on western rivers are being fast-tracked, including the 1,856 MW Sawalkote project on the Chenab, the 260 MW Dulhasti Stage-II, the 624 MW Kiru, the 1,000 MW Pakal Dul, and the 540 MW Kwar projects.
- India suspended the IWT on April 23, 2025, following the Pahalgam terrorist attack (April 22, 2025) that killed 26 people, stating the treaty would remain in abeyance until Pakistan "credibly and irrevocably abjures its support for cross-border terrorism."
- The government has also rejected the jurisdiction of the Permanent Court of Arbitration (PCA) tribunal set up at Pakistan's request regarding disputes over the Kishenganga and Ratle hydroelectric projects.

Indus Waters Treaty 1960: Structure and River Allocation
The Indus Waters Treaty was signed on September 19, 1960, between India and Pakistan, brokered by the World Bank. It governs the use of the six rivers of the Indus basin — considered one of the world's most successful water-sharing agreements for its longevity despite multiple wars between the two countries.
- Eastern Rivers (Ravi, Beas, Sutlej) — allocated to India for unrestricted use.
- Western Rivers (Indus, Jhelum, Chenab) — allocated to Pakistan, but India retains limited rights for irrigation and run-of-the-river hydroelectric generation.
- The western rivers carry approximately 80% of the total mean annual flow (~135 million acre-feet) of the Indus system; eastern rivers carry ~20% (~33 million acre-feet).
- India must give advance notice to Pakistan about construction on western rivers and adhere to design constraints for hydroelectric projects.
- Dispute resolution: Permanent Indus Commission (bilateral), Neutral Expert mechanism, and Court of Arbitration.
- Historically, the treaty survived the 1965 war, the 1971 war, and the Kargil conflict without formal suspension.
Connection to this news: The suspension removes the treaty-mandated constraints on India's use of western rivers for hydropower, enabling projects such as Sawalkote (Chenab) and Pakal Dul (Marusudar, a Chenab tributary) to proceed with greater design flexibility and fewer prior-notification requirements.
India's Hydropower Potential in J&K and Western River Basin
Jammu & Kashmir and Ladakh together hold an estimated hydropower potential of approximately 20,000 MW, much of it on the western rivers (Chenab, Jhelum, and their tributaries) whose harnessing was constrained under IWT provisions. India's total installed hydropower capacity nationally is approximately 47,000 MW (as of 2024), placing it among the world's top hydropower producers.
- Sawalkote (Chenab): 1,856 MW; received environmental clearance in October 2025; estimated cost ~₹31,380 crore.
- Dulhasti Stage-II (Chenab, Kishtwar): 260 MW; environmental clearance granted post-IWT suspension; cost ~₹3,200 crore.
- Pakal Dul (Marusudar River, Chenab tributary): 1,000 MW; target commissioning December 2026.
- Kiru (Chenab): 624 MW; target commissioning March 2028.
- Kwar (Chenab): 540 MW; under development.
- A 46% capacity rise would translate J&K's current hydropower base of roughly 3,800–4,000 MW to approximately 5,500–5,800 MW (specific baseline figure [Unverified]).
Connection to this news: The IWT suspension has catalysed environmental and regulatory clearances that had previously been delayed due to treaty constraints and bilateral consultations, materially accelerating the timeline for J&K's hydropower pipeline.
India-Pakistan Water Disputes and International Law
The IWT's suspension raises questions about treaty law and the doctrine of unilateral suspension. Under the Vienna Convention on the Law of Treaties (VCLT) 1969, a state may invoke the right to suspend a treaty's operation under Article 60 (material breach by other party) or Article 62 (fundamental change of circumstances). India's position implicitly relies on the broader principle of reprisal — suspending treaty obligations in response to Pakistan's alleged support for cross-border terrorism.
- The IWT does not contain a standard termination or suspension clause — it was designed to be permanent.
- Pakistan has disputed India's right to suspend, taking the matter to the Permanent Court of Arbitration (PCA) regarding the Kishenganga and Ratle projects.
- India rejected PCA jurisdiction in February 2026, arguing the appropriate forum is the Neutral Expert mechanism.
- The World Bank, which brokered the IWT, has not formally adjudicated the dispute but has expressed concern over the parallel processes.
- Pakistan's economy is heavily reliant on Indus water, with agriculture — which depends on western river irrigation — accounting for approximately 22% of its GDP and 42% of its workforce.
Connection to this news: India's framing of the suspension as a security response rather than a water-use action creates a precedent in international treaty law linking terrorism attribution to treaty obligations — a question with wider implications for international relations.
Key Facts & Data
- IWT signed: September 19, 1960; brokered by World Bank.
- Western rivers (Pakistan's): Indus, Jhelum, Chenab — ~80% of basin's flow.
- Eastern rivers (India's): Ravi, Beas, Sutlej — ~20% of basin's flow.
- India's suspension date: April 23, 2025; triggered by Pahalgam attack (April 22, 2025, 26 killed).
- J&K projected capacity rise: 46% increase in hydropower capacity.
- Key projects cleared post-suspension: Sawalkote (1,856 MW), Dulhasti Stage-II (260 MW), Kiru (624 MW), Pakal Dul (1,000 MW), Kwar (540 MW).
- India's overall hydropower capacity: ~47,000 MW installed (2024).
- PCA jurisdiction rejected: India rejected PCA's authority in February 2026; favours Neutral Expert mechanism.
- Vienna Convention context: Articles 60 and 62 VCLT provide legal basis for treaty suspension under material breach or fundamental change of circumstances.
