Quick Revision: The Siang Upper Multipurpose Project (SUMP) is a proposed 11,000 MW hydropower initiative in Arunachal Pradesh, declared a national project in 2008, aimed at enhancing India’s energy and water security amid China’s upstream hydropower expansion on the Yarlung Tsangpo.

Why is this in the news?

The Arunachal Pradesh State Cabinet has constituted an Empowered High-Level Committee to oversee the pre-feasibility survey for the Siang Upper Multipurpose Project (SUMP), a proposed 11,000 MW hydropower initiative on the Siang River. This development follows local protests against the survey, highlighting tensions between developmental imperatives and community concerns. The project, declared a national project in 2008, is framed as critical for India’s energy and water security amid China’s upstream hydropower expansion on the Yarlung Tsangpo, underscoring broader geopolitical and governance dimensions.

Background

• The Siang River, originating in Tibet as the Yarlung Tsangpo, flows into Arunachal Pradesh and merges with the Dibang and Lohit rivers to form the Brahmaputra, a lifeline for millions in India and Bangladesh.
• China has been constructing multiple hydropower projects on the Yarlung Tsangpo, with a cumulative capacity exceeding 60,000 MW, raising concerns in India about downstream water flow, sedimentation, and ecological impacts.
• The Siang Upper Multipurpose Project (SUMP) was declared a national project by the Government of India in 2008, prioritising its development for strategic, economic, and energy security reasons.
• Arunachal Pradesh, with significant hydropower potential (~50,000 MW), has been a focal point for large-scale hydroelectric projects, though many face opposition due to environmental and social concerns.
• The Brahmaputra River Basin is a shared resource, governed by limited bilateral mechanisms between India and China, necessitating proactive domestic water resource management.
• Local communities in Siang and Upper Siang districts have raised objections to the pre-feasibility survey, citing misinformation, displacement risks, and ecological degradation.

What is the Siang Upper Multipurpose Project (SUMP)?

• The SUMP is a proposed 11,000 MW (or more) multipurpose hydropower project on the Siang River in Arunachal Pradesh, designed for electricity generation, flood mitigation, and water resource management.
• The project is classified as a ‘national project’ under the Government of India’s National Hydroelectric Power Corporation (NHPC) initiative, signifying its strategic importance for energy and water security.
• The project aims to harness the hydropower potential of the Siang River, which is part of the Brahmaputra Basin, a critical transboundary river system.
• Key objectives include generating clean energy, reducing flood risks in the Siang-Brahmaputra basin, creating employment opportunities, and fostering socio-economic development in the region.
• The project involves three proposed dam sites: two in Siang district and one in Upper Siang district, with the potential to significantly alter river flow dynamics and sediment transport.
• Environmental safeguards and social impact assessments are mandated under the Environmental Impact Assessment (EIA) Notification, 2006, and the Forest (Conservation) Act, 1980, to address ecological and community concerns.
• The project is framed as a countermeasure to China’s upstream hydropower development on the Yarlung Tsangpo, which has raised geopolitical and hydrological concerns in India.
• Public consultations and stakeholder engagement are integral to the pre-feasibility and feasibility study phases, as per the EIA Notification, 2006, to ensure transparency and address local grievances.

Prelims Practice Questions

Q1. Consider the following statements regarding the Siang Upper Multipurpose Project (SUMP):

1. The SUMP has been declared a National Project by the Union Government.
2. The project aims to generate an estimated 11,000 MW of hydroelectricity.
3. The project is located entirely within Arunachal Pradesh and does not involve any transboundary considerations.

How many of the above statements are correct?

1. Only one
2. Only two
3. All three
4. None

Answer: Only two — Statement 1 is correct: SUMP was declared a National Project in 2008. Statement 2 is correct: The project is estimated to generate 11,000 MW of electricity. Statement 3 is incorrect: The Siang River is a transboundary river, flowing from Tibet (China) into Arunachal Pradesh as the Siang, before joining the Brahmaputra in Assam.

Q2. Assertion (A): The Siang Upper Multipurpose Project (SUMP) is envisaged to strengthen water and energy security in India.
Reason (R): The project is expected to mitigate floods in the Siang-Brahmaputra basin and generate significant hydroelectric power.

1. Both A and R are true, and R is the correct explanation of A
2. Both A and R are true, but R is not the correct explanation of A
3. A is true, but R is false
4. A is false, but R is true

Answer: Both A and R are true, and R is the correct explanation of A — Both the Assertion (A) and Reason (R) are true. The SUMP is designed to enhance water and energy security by generating hydroelectric power and mitigating floods in the Siang-Brahmaputra basin. However, R explains A but is not the sole reason for the assertion.

Q3. Match the following pairs related to river governance in India:

Column I (River Projects)
A. Siang Upper Multipurpose Project (SUMP)
B. Sardar Sarovar Project
C. Tehri Hydroelectric Project
D. Nathpa Jhakri Project

Column II (State/Union Territory)
1. Gujarat
2. Arunachal Pradesh
3. Uttarakhand
4. Himachal Pradesh

1. A-2, B-1, C-3, D-4; A-1, B-2, C-3, D-4; A-3, B-1, C-2, D-4; A-4, B-3, C-1, D-2
