India Fast-Tracks Hydroelectric Projects on Chenab River

The Government of India has accelerated the development of four hydroelectric projects on the Chenab River and its tributaries. This decision comes amid heightened tensions with Pakistan, particularly following a terrorist incident in Pahalgam. The projects include Pakal Dul (1,000 MW), Ratle (850 MW), Kiru (624 MW), and Kwar (540 MW). All are situated in Jammu and Kashmir’s Kishtwar district.

Overview of the Projects

The Pakal Dul project is notable as Jammu and Kashmir’s first water storage initiative. The remaining projects, Ratle, Kiru, and Kwar, will have limited storage capacity. The Central Electricity Authority (CEA) has provided estimates for their completion. Pakal Dul and Kiru are expected to be operational by September 2026. Kwar and Ratle are projected for December 2027 and November 2028, respectively. These timelines may be expedited due to the current urgency.

Impact of the Indus Waters Treaty

India has put the Indus Waters Treaty with Pakistan on hold following recent security incidents. This treaty governs the sharing of river waters between the two nations. The suspension has led to India lowering the sluice gates at the Baglihar dam, a run-of-the-river project, as a short-term measure to restrict water flow to Pakistan’s Punjab region.

Characteristics of Run-of-the-River Projects

Run-of-the-river projects typically do not store large volumes of water. However, they can regulate flow by adjusting sluice gates. This is particularly useful during low discharge periods, such as before the summer and monsoon seasons. The four projects will enhance India’s capacity to manage water resources in the region.

Storage Capacities and Future Projections

Pakal Dul, once completed, will be the largest hydropower project in Jammu and Kashmir. It will have a live storage capacity of approximately 109 million cubic metres (mcm). In comparison, the Ratle project will have around 24 mcm, Kiru will feature 10.5 mcm, and Kwar will hold 9.2 mcm. The Baglihar dam, currently the largest at 900 MW, has a storage capacity of only 30 mcm.

Strategic Importance of Hydropower

These projects are strategically for India. They will not only contribute to energy security but also allow for better control of water resources. Enhanced hydropower capacity can also strengthen India’s position in regional water disputes.

Environmental Considerations

While hydroelectric projects provide renewable energy, they can also impact local ecosystems. Careful planning and management are essential to mitigate any adverse environmental effects. Sustainable practices should be incorporated into the project designs.

Future Developments

As the projects progress, India may continue to review its water management strategies. The ongoing geopolitical situation will likely influence future decisions regarding water resource allocation and energy production in the region.

Questions for UPSC:

1. Critically analyse the implications of the Indus Waters Treaty on India-Pakistan relations.
2. What are the advantages of run-of-the-river hydroelectric projects? Explain with suitable examples.
3. Estimate the potential environmental impacts of large-scale hydropower projects in Jammu and Kashmir.
4. Point out the strategic significance of hydropower for national security in India.

Answer Hints:

1. Critically analyse the implications of the Indus Waters Treaty on India-Pakistan relations.

1. The Indus Waters Treaty was signed in 1960, regulating water sharing between India and Pakistan.
2. Recent tensions, particularly after terrorist attacks, have led India to put the treaty on hold.
3. India’s actions, like lowering sluice gates, reflect a shift towards using water as a strategic resource.
4. The treaty’s suspension may exacerbate existing conflicts over water resources in the region.
5. Long-term implications include potential international disputes and impact on regional stability.

2. What are the advantages of run-of-the-river hydroelectric projects? Explain with suitable examples.

1. Run-of-the-river projects utilize the natural flow of rivers, minimizing ecological disruption.
2. They typically require less investment and construction time compared to large storage dams.
3. Example – The Baglihar dam is a successful run-of-the-river project that generates power.
4. These projects can provide renewable energy while having a lower carbon footprint.
5. They allow for seasonal flow management, benefiting irrigation and local ecosystems.

3. Estimate the potential environmental impacts of large-scale hydropower projects in Jammu and Kashmir.

1. Large-scale hydropower projects can disrupt local ecosystems and wildlife habitats.
2. Construction can lead to soil erosion and sedimentation in rivers, affecting water quality.
3. Changes in water flow can impact agriculture and fisheries downstream.
4. Potential displacement of local communities due to dam construction and flooding.
5. Mitigation strategies are essential to reduce negative environmental impacts.

4. Point out the strategic significance of hydropower for national security in India.

1. Hydropower enhances energy security, reducing dependence on fossil fuels.
2. Control over water resources can be leveraged in geopolitical negotiations with neighboring countries.
3. Increased hydropower capacity strengthens India’s ability to manage water disputes with Pakistan.
4. Hydropower projects can create jobs and stimulate economic growth in border regions.
5. Strategic infrastructure development can boost defense capabilities in sensitive areas.
