India and Bhutan to Strengthen Cooperation in the Power Sector

1. At a Glance

• Bilateral hydropower partnership is the flagship pillar of India–Bhutan economic ties, with India as the sole buyer of Bhutan's surplus hydroelectricity [1][3].
• Cooperation began in 1961, formalised by the 2006 Agreement on Cooperation in Hydroelectric Power, and was reaffirmed in a Feb 2026 ministerial meeting in New Delhi [1].
• Strategically central to UPSC: intersects GS-II (neighbourhood policy), GS-III (energy security, clean energy), and India's "Neighbourhood First" + Act East doctrines.

2. Why in the News

• On 3 Feb 2026, Bhutan's Minister of Energy & Natural Resources Lyonpo Gem Tshering met Union Power Minister Manohar Lal and MoS Power & NRE Shripad Naik in New Delhi to deepen power-sector cooperation [1].
• Both sides discussed commercial optimisation of the 1020 MW Punatsangchhu-II and early commissioning of the 1200 MW Punatsangchhu-I projects [1].
• Punatsangchhu-II was jointly inaugurated on 11 Nov 2025 by PM Modi and King Jigme Khesar; surplus power export to India began 19 Sep 2025 [2].
• Dam concrete pour ceremony at Punatsangchhu-I held on 10 April 2026 during Manohar Lal's Bhutan visit [2][4].

3. Background & Evolution

• 1961: Indo-Bhutan hydropower cooperation initiated [1].
• 1974: Chukha HEP (336 MW) — first major joint project; commissioned 1986–88.
• 2006: Agreement on Cooperation in Hydroelectric Power signed [1].
• 2008: Protocol envisaging 10,000 MW of hydropower import from Bhutan by 2020 [5].
• 2009: Inter-Governmental Agreement on Punatsangchhu-I.
• Commissioned projects: Chukha (336 MW), Kurichhu (60 MW), Tala (1020 MW), Mangdechhu (720 MW, 2019).
• 2024: Joint Vision Statement on India–Bhutan Energy Partnership [6].
• 2025: Punatsangchhu-II inaugurated [2].

4. Core Static Facts

• Implementing Ministry (India): Ministry of Power [1].
• Nodal PSU: NHPC / Central Electricity Authority (CEA); financing via GoI grants + loans.
• Punatsangchhu-I HEP: 1200 MW, on Punatsangchhu river, Wangdue Phodrang dzongkhag; run-of-river [1].
• Punatsangchhu-II HEP: 1020 MW; commissioned 2025 [1][2].
• Sankosh HEP: reservoir-based, ~2585 MW (planned) — discussed in Feb 2026 meeting [2].
• Tariff framework: bilateral cost-plus tariff; Tariff Protocol for Punatsangchhu-II signed 2025 [2].
• Bhutan is not a SAARC energy ring member in the cross-border power trade — but bilateral CBET (Cross-Border Electricity Trade) regulations of CERC (2018, amended) govern imports.

5. Multi-Dimensional Analysis

Economic

• Hydropower exports contribute ~25–30 % of Bhutan's revenue and ~14 % of its GDP — anchors Bhutan's fiscal stability.
• India gains clean baseload power in eastern grid; reduces dependence on coal.

Geopolitical / Strategic

• Counters Chinese inroads in Bhutan amid the Doklam (2017) legacy and ongoing Bhutan–China boundary talks.
• "Neighbourhood First" anchor; Bhutan one of two neighbours (with Nepal) where India is a net power importer, deepening interdependence.

Environmental

• All projects are run-of-river (low submergence) — except Sankosh (storage); aligns with India's NDC target of 50% non-fossil installed capacity by 2030 (UNFCCC submission).
• Concerns: Himalayan seismic zone V; Punatsangchhu-I delays due to geological instability on right bank since 2013.

Administrative

• Inter-Governmental (IG) mode (cost-plus, govt-to-govt) vs Joint Venture (JV) mode (e.g., Kholongchhu — JV with SJVN, paused 2020).
• Cost overruns and time slippages on Punatsangchhu-I are key administrative lesson.

6. Recent Developments (last 12-18 months)

• Feb 2026: Bhutan Energy Minister–Manohar Lal meeting in Delhi [1].
• April 2026: Manohar Lal's 4-day Bhutan visit; concrete pour ceremony at P-I dam [2][4].
• 11 Nov 2025: Joint inauguration of Punatsangchhu-II by PM Modi & King of Bhutan [2].
• 19 Sep 2025: Punatsangchhu-II began commercial export to India [2].
• March 2024: PM Modi's state visit to Bhutan; Joint Vision Statement on Energy Partnership [3][6].

7. Prelims Hooks

• Indo-Bhutan hydropower cooperation began in 1961 [1].
• Bilateral hydroelectric power cooperation Agreement signed in 2006 [1].
• Punatsangchhu-I = 1200 MW; Punatsangchhu-II = 1020 MW [1].
• Both Punatsangchhu projects are on the Punatsangchhu (Sankosh tributary) river in western Bhutan.
• 2008 protocol envisaged 10,000 MW import from Bhutan [5].
• Punatsangchhu-II commercial export to India began 19 September 2025 [2].
• Joint inauguration of Punatsangchhu-II: 11 November 2025 by PM Modi and King Jigme Khesar Namgyel Wangchuck [2].
• Concrete-pour at Punatsangchhu-I dam: 10 April 2026 [2].
• Indian nodal ministry: Ministry of Power (NOT MEA) [1].
• Mangdechhu HEP (720 MW) commissioned 2019; Tala HEP (1020 MW) is the largest commissioned hydropower project in Bhutan pre-Punatsangchhu-II.
• Chukha (336 MW) — first major Indo-Bhutan project.
• Bhutan's Energy Minister (2026): Lyonpo Gem Tshering [1].
• Indian Power Minister (2026): Manohar Lal (also Housing & Urban Affairs) [1].
• Sankosh HEP is reservoir-based (storage), distinguishing it from run-of-river Punatsangchhu schemes [2].

8. Mains Relevance

• GS-II: India and its neighbourhood; bilateral relations.
• GS-III: Energy security; infrastructure.
• Possible stems:
• "Hydropower is the bedrock of India–Bhutan relations but is now being tested by geopolitical and ecological pressures. Discuss."
• "Examine the role of cross-border electricity trade in advancing India's Neighbourhood First policy."
• "Critically evaluate the delays in the Punatsangchhu-I HEP and the lessons for transboundary hydropower projects in the Himalayas."

10. Common Errors / Trap Areas

• Confusing Punatsangchhu-I (1200 MW) with Punatsangchhu-II (1020 MW) — capacities are often swapped in MCQs [1].
• Treating the Indian nodal ministry as MEA — it is the Ministry of Power for project implementation [1].
• Assuming Punatsangchhu projects are storage dams — they are run-of-river; Sankosh is the storage scheme.
• Year confusion: cooperation began 1961, hydropower agreement is 2006, 10,000 MW protocol is 2008 [1][5].
• Misattributing Mangdechhu (720 MW) as the largest — Tala (1020 MW) and now Punatsangchhu-II (1020 MW) match; Punatsangchhu-I (1200 MW) will be the largest once commissioned [2].
