Kalai-II Hydro Electric Project (1200 MW) — UPSC Study Note
1. At a Glance
- Kalai-II HEP is a 1200 MW run-of-the-Lohit-river hydro project in Anjaw district, Arunachal Pradesh, cleared by the Cabinet Committee on Economic Affairs (CCEA) on 8 April 2026 at an outlay of ₹14,105.83 crore [S1].
- It is the first hydro project in the Lohit Basin, to be executed by a JV of THDC India Ltd. and Govt. of Arunachal Pradesh [S1].
- Examinable as a node in India's NE hydro push, non-fossil 500 GW by 2030 target, and federal hydro-PSU stalled-project revival policy [S2].
2. Why in the News
- CCEA approval on 8 April 2026 of ₹14,105.83 cr investment for Kalai-II on Lohit river, Anjaw district [S1].
- Announced alongside CCEA clearance of the 1720 MW Kamala HEP (₹26,069.50 cr) in Kamle/Kra Daadi/Kurung Kumey districts — signalling a fresh round of large NE hydro commitments [S3].
3. Background & Evolution
- Arunachal hosts ~40% of India's assessed hydro potential; many projects stalled since 2000s under private MoU regime.
- August 2023: 12 stalled HEPs aggregating >11.5 GW in Arunachal Pradesh transferred from private developers to Central Hydro PSUs (NHPC, SJVN, NEEPCO, THDC) under Ministry of Power [S2].
- Kalai-II, originally allotted to a private developer, was among projects re-assigned to THDC India Ltd. under this 2023 reset [S2].
- 2019 Cabinet measures to promote hydro: large hydro declared Renewable Energy, Hydro Purchase Obligation (HPO), tariff rationalisation, and budgetary support for enabling infrastructure (roads/bridges/transmission) [S4].
4. Core Static Facts
- Project: Kalai-II HEP [S1].
- River / Basin: Lohit river (Brahmaputra tributary) — first HEP in Lohit Basin [S1].
- Location: Anjaw district, Arunachal Pradesh [S1].
- Installed capacity: 1200 MW = 6 × 190 MW + 1 × 60 MW [S1].
- Annual generation: 4852.95 Million Units (MU) [S1].
- Outlay: ₹14,105.83 crore [S1].
- Completion period: 78 months [S1].
- Implementing entity: JV — THDC India Ltd. + Govt. of Arunachal Pradesh [S1].
- GoI budgetary support for enabling infrastructure: ₹599.88 crore (roads, bridges, associated transmission line) [S1].
- Central Financial Assistance (CFA) toward State equity: ₹750 crore [S1].
- Parent Ministry: Ministry of Power (THDC is a CPSE under MoP) [S2].
- Approving body: CCEA, chaired by PM [S1].
5. Multi-Dimensional Analysis
Economic - Adds 4,852.95 MU/yr of dispatchable peaking power to support peak demand management and national grid balancing [S1]. - ₹14,105.83 cr capex into a remote frontier district; State gets equity via ₹750 cr CFA — fiscal federalism through the enabling-infrastructure scheme [S1][S4].
Strategic / Geopolitical - Lohit basin lies close to the McMahon Line / LAC with China; first hydro on Lohit asserts upstream user rights on a Brahmaputra tributary as China plans large dams on the Yarlung Tsangpo. - Strengthens State power supply in a frontier border district (Anjaw borders Tibet/Myanmar) [S1].
Environmental - Large hydro is classified as Renewable Energy since the 2019 Cabinet reform — contributes to non-fossil 500 GW by 2030 and Panchamrit climate commitments [S4]. - Lohit/Eastern Himalaya is in a seismic Zone V, biodiversity-rich, with downstream concerns in Assam (cumulative impact, Dibang/Lohit/Siang) — risks of forest diversion and tribal displacement.
Administrative / Federal - Model = Centre-State JV via Central PSU (THDC) replacing private MoU model that had stalled 12 projects [S2]. - Uses the modified Budgetary Support for Enabling Infrastructure scheme (roads, bridges, transmission), revised by Cabinet to deepen support for remote NE projects [S4].
6. Recent Developments (last 12–18 months)
- 08 Apr 2026: CCEA approves Kalai-II (1200 MW) — ₹14,105.83 cr [S1].
- 08 Apr 2026: CCEA approves Kamala HEP (1720 MW) — ₹26,069.50 cr in Kamle/Kra Daadi/Kurung Kumey [S3].
- 2023: 12 stalled Arunachal HEPs (>11.5 GW) handed to NHPC/SJVN/NEEPCO/THDC [S2].
- Cabinet modification of Budgetary Support for Enabling Infrastructure scheme to widen coverage to NE projects [S4].
7. Prelims Hooks
- Kalai-II is on the Lohit river, a tributary of the Brahmaputra [S1].
- District: Anjaw, Arunachal Pradesh [S1].
- Capacity configuration: 6 × 190 MW + 1 × 60 MW = 1200 MW [S1].
- Annual generation: 4852.95 MU [S1].
- Outlay: ₹14,105.83 crore; completion: 78 months [S1].
- Developer: JV of THDC India Ltd. and Govt. of Arunachal Pradesh [S1].
- First hydro project in the Lohit Basin [S1].
- GoI enabling-infrastructure support: ₹599.88 crore; State equity CFA: ₹750 crore [S1].
- Approving authority: CCEA (not the full Union Cabinet, not CCS) [S1].
- In 2023, 12 stalled Arunachal HEPs (>11.5 GW) were reassigned to Central Hydro PSUs [S2].
- Since 2019, Large Hydro is classified as Renewable Energy; HPO introduced [S4].
- Parent Ministry: Ministry of Power (not MNRE, even though hydro counts as RE) [S2][S4].
8. Mains Relevance
- GS-III — Infrastructure: Energy (hydro in non-fossil mix); GS-III — Environment (cumulative EIA in Eastern Himalaya); GS-II — Federalism (Centre-State JV model); GS-II — IR (transboundary rivers with China).
- Likely stems: 1. "Discuss the strategic and ecological trade-offs of accelerating large hydro in the Eastern Himalaya. Examine the Centre-State JV-via-PSU model as a remedy for stalled projects." 2. "Large hydro is essential to balance India's variable renewable portfolio. Critically evaluate in the context of recent CCEA approvals in Arunachal Pradesh." 3. "Examine the geopolitical dimensions of Brahmaputra tributary hydro development."
9. Related Topics to Study Next
- 2019 Hydro Sector Reforms — HPO, large-hydro-as-RE, tariff rationalisation [S4].
- Dibang Multipurpose Project (2880 MW) — Arunachal flagship, also Brahmaputra tributary.
- Subansiri Lower HEP — long-stalled NE hydro, Assam-Arunachal interface.
- Yarlung Tsangpo / Medog dam (China) — upstream-downstream geopolitics.
- THDC, NHPC, SJVN, NEEPCO — Central Hydro PSUs under MoP.
- Panchamrit & 500 GW non-fossil by 2030 target.
- Anjaw district / Lohit valley — borders Tibet & Myanmar; Walong battle site.
- EIA Notification & Forest (Conservation) Act processes for NE HEPs.
10. Common Errors / Trap Areas
- River: Kalai-II is on the Lohit — not Siang, Subansiri, or Dibang.
- District: Anjaw, not Lohit district (the river crosses both).
- Approver: CCEA, not the Union Cabinet or CCS.
- Implementer: THDC India Ltd. (not NHPC, SJVN, or NEEPCO) in JV with the State.
- Ministry: Comes under Ministry of Power, even though large hydro is counted as Renewable Energy — don't tag it to MNRE.
- Distinguish Kalai-II (1200 MW, Lohit) from the Kamala HEP (1720 MW) approved the same day in central Arunachal [S3].
