4. Core Static Facts
- Implementing ministry (India): Ministry of Power [S1].
- Punatsangchhu-II HEP: 1020 MW (6 × 170 MW), run-of-the-river, on Punatsangchhu river, Wangdue Phodrang district, Bhutan [S6][S7].
- Funding pattern: 30% grant + 70% loan at 10% p.a., 30 semi-annual instalments [S6].
- EPC partner: BHEL commissioned multiple units [S7].
- Total Indo-Bhutan jointly developed HEPs: 5 projects totalling 3156 MW (Chukha 336 + Kurichhu 60 + Tala 1020 + Mangdechhu 720 + Punatsangchhu-II 1020) [S4].
- Punatsangchhu-II raises Bhutan's installed capacity by ~40% to >3500 MW [S6].
- Bhutan PM: Tshering Tobgay; counterpart bodies: Bhutan Ministry of Energy & Natural Resources (MoENR) [S1][S6].
5. Multi-Dimensional Analysis
Geopolitical / Strategic - Hydropower is the strategic ballast of Indo-Bhutan ties — counters Chinese inroads via boundary talks and infrastructure diplomacy [S4]. - Aligns with Neighbourhood First and Act East energy connectivity vision (BBIN sub-regional grid) [S4].
Economic - Bhutan's hydropower export revenue to India is the single largest contributor to its GDP and balance of payments [S4]. - The Tariff Protocol locks in a mutually agreed starting tariff, providing revenue predictability for Bhutan and price-stable RE supply to India [S2].
Environmental / Energy Transition - Supports India's commitment of 500 GW non-fossil capacity by 2030 (Panchamrit) by importing clean hydro [S4]. - Bhutan remains the world's only carbon-negative country — exports of surplus hydro displace fossil generation in eastern India [S6].
Scientific / Technological - Reactive Energy Accounting Methodology addresses VAR management for cross-border grid stability — improves voltage regulation, reduces losses [S1]. - Builds capacity for synchronous interconnection under One Sun One World One Grid (OSOWOG) [S4].
Administrative - Enhanced bilateral institutional mechanism for periodic review covering non-hydro energy, cross-border transmission, project financing, capacity building [S1].
6. Recent Developments (last 12-18 months)

10. Common Errors / Trap Areas
- Wrong river: Punatsangchhu-II is on the Punatsangchhu (not Mangdechhu or Kurichhu).
- Wrong capacity split: It is 6×170 MW = 1020 MW, often confused with Tala HEP (also 1020 MW).
- Wrong ministry portfolio: Manohar Lal holds Power + Housing & Urban Affairs; not MEA.
- Funding ratio mistake: It is 30% grant / 70% loan, not 50:50 or 60:40.
- Run-of-the-river vs storage: Punatsangchhu-II is RoR, not a large reservoir/storage dam.
- Confusing Joint Vision Statement (2024) with the 2014 IGA on JV Hydro Projects — two distinct instruments.
