No new hydel projects can come up in upper Ganga, govt. tells SC

1. At a Glance

• Union government (2026) told the Supreme Court it opposes any new hydroelectric projects in the Alaknanda and Bhagirathi river basins (upper Ganga) in Uttarakhand, permitting only 7 already-commissioned/near-complete projects [S4].
• Marks a policy reversal — the Power Ministry had argued for up to 8 additional projects as recently as November 2024 [S4].
• Tests environment-development tradeoffs, Himalayan ecology, federal coordination (CABSEC), and SC's environmental jurisprudence — a recurring GS-II/GS-III theme (post-Kedarnath 2013, post-Joshimath 2023).
• Ties directly to the long-running SC case on Himalayan hydel projects and glacial/riverine ecology originating from the 2013 Uttarakhand disaster.

2. Why in the News

• A common affidavit filed on 19 May 2026 by three Union Ministries — Environment (MoEFCC), Jal Shakti, and Power — before the Supreme Court, stating no new hydel project should be permitted in the Alaknanda-Bhagirathi basins beyond the seven already approved [S4][S1].
• Reported by The Hindu on 21 May 2026 [S4]; corroborated by Down To Earth and LiveLaw [S1][S2].
• Notable because it reflects a unified inter-ministerial stance, ending earlier inter-ministerial divergence (Power Ministry previously favoured more projects) [S4].

3. Background & Evolution

• Litigation traces to concerns raised after the June 2013 Kedarnath/Uttarakhand flash floods, which triggered scrutiny of hydel projects' role in disaster amplification [S1].
• A high-level committee (CABSEC), chaired by the Cabinet Secretary, with secretaries of MoEFCC, Power, Jal Shakti, and the Uttarakhand Chief Secretary, was tasked with examining the matter [S1].
• Key disaster milestones cited in the affidavit: Chamoli earthquake (1999), Kedarnath flood (2013), Rishiganga flood (February 2021) that damaged the Tapovan Vishnugad project, Joshimath land subsidence (2023), and Dharali flash flood (August 2025) [S1].
• Earlier stance (November 2024): Power Ministry supported up to 8 new projects; current affidavit reverses this to zero new projects [S4].

4. Core Static Facts

5. Multi-Dimensional Analysis

Environmental - Recognises cumulative ecological carrying capacity limits of a seismically active, glacially-fed river system [S1]. - Formalises a minimum environmental flow (e-flow) requirement — a rare concrete hydrological safeguard [S1].

Legal/Constitutional - Arises from ongoing Supreme Court PIL/writ jurisdiction on environmental protection (Article 21 — right to a healthy environment; Article 32) — pattern consistent with earlier SC interventions post-2013 disaster. - Reflects the precautionary principle and inter-generational equity, doctrines the SC has invoked in environmental cases.

Administrative/Governance - Demonstrates inter-ministerial policy convergence via CABSEC after years of Power Ministry pushing a contrary line — a governance case study in Centre-level coordination [S1][S4]. - Raises Centre-State coordination questions given Uttarakhand's Chief Secretary's participation and the state's dependence on hydel revenue.

Economic - Foregoes future hydel capacity addition in a state historically positioned as a "hydropower powerhouse," with implications for Uttarakhand's energy revenue and India's renewable/hydro targets.

Scientific/Disaster Management - Affidavit explicitly links dam-building in fragile zones to disaster amplification, citing Rishiganga (2021) and Joshimath (2023) as evidence [S1].

6. Recent Developments (last 12–18 months)

• August 2025: Dharali flash flood cited as fresh evidence of basin fragility [S1].
• November 2024: Power Ministry had sought approval for 8 new projects — position later reversed [S4].
• 19 May 2026: Common affidavit filed by three ministries opposing new projects [S4].
• 21 May 2026: Reported by The Hindu [S4].
• 25 May 2026: Commentary (SANDRP) welcomed the decision, calling for similar restrictions across the wider Himalayan region [S3].

7. Prelims Hooks

• Common affidavit filed in SC on 19 May 2026 by MoEFCC, Jal Shakti, and Power Ministries.
• No new hydel projects allowed beyond 7 in Alaknanda-Bhagirathi basins, Uttarakhand.
• Total capacity of the 7 permitted projects: ~2,150 MW.
• Tehri Pumped Storage Project — 1,000 MW — largest among the seven, on the Bhagirathi.
• Tapovan Vishnugad (520 MW, Dhauliganga) was damaged in the February 2021 Rishiganga flood, Chamoli district.
• Vishnugad Pipalkoti — 444 MW — on the Alaknanda.
• Singoli Bhatwari (99 MW) and Phata Byung (76 MW) — both on the Mandakini river.
• Mandated minimum e-flow: 1,000 cusecs on Alaknanda, Bhagirathi, Mandakini.
• Coordinating body: CABSEC, chaired by the Cabinet Secretary.
• Power Ministry had earlier (Nov 2024) favoured 8 new projects — reversed in the 2026 affidavit.
• Disasters cited: Chamoli earthquake (1999), Kedarnath floods (2013), Rishiganga flood (2021), Joshimath subsidence (2023), Dharali flash flood (Aug 2025).
• The rivers Alaknanda and Bhagirathi together form the Ganga at Devprayag.

8. Mains Relevance

• GS-III: Environment & Ecology — conservation, environmental impact assessment, disaster management (Himalayan ecology, hydel projects vs sustainability).
• GS-II: Governance — inter-ministerial coordination, federalism (Centre-State on natural resource use), judiciary's role in environmental policy.
• GS-I: Geography — river systems, Himalayan geomorphology, disaster-prone zones.
• Possible question stems: 1. "Discuss the ecological rationale behind restricting hydroelectric development in the upper reaches of the Ganga. How does this reflect the tension between energy needs and environmental sustainability in the Himalayas?" 2. "Examine the role of the judiciary in shaping environmental policy for fragile ecosystems in India, with reference to recent Supreme Court interventions on Himalayan hydel projects." 3. "Critically analyse the governance challenges in achieving inter-ministerial and Centre-State consensus on environmentally sensitive infrastructure projects."

9. Related Topics to Study Next

• Joshimath land subsidence (2023) — direct evidence cited in the affidavit; same seismic-fragile zone.
• Char Dham All-Weather Road project — parallel SC litigation on Himalayan ecological carrying capacity.
• Kedarnath 2013 flash floods — originating trigger for hydel project scrutiny.
• Environmental Flow (e-flow) norms — link to Ganga rejuvenation and Namami Gange.
• Namami Gange Programme — broader Ganga conservation policy under Jal Shakti Ministry.
• Wildlife Institute of India / carrying capacity studies of Himalayan states — scientific basis for such restrictions.
• National Green Tribunal (NGT) jurisprudence on riverine ecosystems — comparative forum to SC.
• Seismic zoning of Uttarakhand (Zone IV/V) — geography-disaster management linkage.

10. Common Errors / Trap Areas

• Don't confuse Alaknanda-Bhagirathi basin restriction with a blanket ban on all Himalayan hydel projects — it is basin/state-specific (Uttarakhand only).
• Do not attribute the affidavit solely to MoEFCC — it is a joint affidavit of three ministries (Environment, Jal Shakti, Power).
• Avoid confusing Tapovan Vishnugad (damaged in 2021 Rishiganga flood) with Tehri (undamaged, largest, pumped-storage) — commonly mixed up in MCQs.
• Remember Alaknanda and Bhagirathi confluence forms the Ganga at Devprayag, not Rishikesh or Haridwar.
• The "7 projects" figure is cumulative status (some operational, some under construction) — not all newly sanctioned.
