Cabinet approves Investment Proposal for construction of 1720 MW Kamala Hydro Electric Project in Kamle, Kra Daadi & Kurung Kumey Districts of Arunachal Pradesh with an outlay of Rs.26,069.50 crore

1. At a Glance

• Kamala HEP: a 1720 MW storage-based hydro project on the Kamala river (tributary of the Subansiri, itself a tributary of the Brahmaputra) in Arunachal Pradesh, approved by the Cabinet Committee on Economic Affairs (CCEA) on 8 April 2026 with an outlay of Rs 26,069.50 crore [1].
• Largest among the recent batch of NE hydro approvals; integral to India's push to harness Arunachal's ~50,000 MW hydro potential and to deliver flood moderation to the Brahmaputra valley [1][2].

2. Why in the News

• CCEA approval on 8 April 2026 for investment of Rs 26,069.50 crore; estimated completion 96 months; expected generation 6,870 MU/year [1].
• Part of a cluster of CCEA approvals the same day including 1200 MW Kalai-II HEP (Anjaw, Rs 14,105.83 cr) [1].

3. Background & Evolution

• Kamala HEP first appears in Pre-Feasibility Report submitted to MoEFCC (2018) for environment clearance / Terms of Reference [2].
• August 2023: 12 stalled hydro projects (>11.5 GW) in Arunachal handed over to central hydro PSUs (NHPC, NEEPCO, SJVN, THDC) under Ministry of Power [1].
• Subsequent CCEA approvals in the NE pipeline: Tato-I (186 MW), Heo (240 MW) in Shi Yomi (2024); Tato-II (700 MW) (2025); Kamala (1720 MW) & Kalai-II (1200 MW) (April 2026) [1].
• Builds on the 2008 Hydro Policy and the March 2019 Cabinet measures declaring large hydro (>25 MW) as renewable energy with HPO, tariff support, budgetary support for flood moderation and enabling infrastructure [1].

4. Core Static Facts

• Project: Kamala Hydro Electric Project (HEP) [1].
• Capacity: 1720 MW = 8 × 210 MW + 1 × 40 MW [1].
• Annual generation: 6,870 MU (≈6,869.92 MU) [1][2].
• River: Kamala river, tributary of Subansiri (Brahmaputra basin) [2].
• Location: Kamle, Kra Daadi & Kurung Kumey districts, Arunachal Pradesh [1].
• Dam: 216 m concrete gravity dam with underground powerhouse; storage scheme [2].
• Cost: Rs 26,069.50 crore [1].
• Implementation: Joint Venture — NHPC Ltd (74%) + Govt of Arunachal Pradesh (26%) on BOOT basis [2].
• Completion: 96 months [1].
• Central budgetary support: Rs 4,743.98 cr for flood moderation; Rs 1,340 cr for enabling infrastructure (roads, bridges, transmission); Rs 750 cr Central Financial Assistance towards State equity [1].
• State benefits: 12% free power to Arunachal Pradesh + 1% for Local Area Development Fund (LADF); ~196 km of roads/bridges in the three districts [1].
• Nodal Ministry: Ministry of Power; CCEA chaired by PM [1].

5. Multi-Dimensional Analysis

Economic

• Boosts North-East power exports; enables peak demand management & grid balancing of national grid [1].
• Large capex stimulates construction-linked employment in Arunachal; ~196 km road network spinoff [1].

Environmental

• Provides flood moderation in the Brahmaputra valley — a recurrent flood-prone region [1][2].
• Concerns: 216 m high dam in seismically active Zone V Eastern Himalaya; submergence, biodiversity impact on Subansiri sub-basin [2].
• Counts toward India's non-fossil 500 GW by 2030 target; large hydro classified as renewable since 2019 [1].

Geopolitical / Strategic

• Arunachal hydro build-out asserts Indian sovereignty against Chinese counter-claims and counters upstream Chinese dam-building on the Yarlung Tsangpo / Brahmaputra [1].
• Strengthens border-area infrastructure (roads, transmission) under the Vibrant Villages/border development logic.

Administrative / Federal

• JV model (NHPC + State) replicates the August 2023 reallocation of stalled projects to central PSUs [1].
• 12% free power + 1% LADF is the standard CEA-mandated fiscal devolution to host state [1].

Social / Tribal

• Districts are predominantly Nyishi, Apatani, Galo tribal areas under Sixth Schedule-adjacent Inner Line Permit regime; FRA, R&R, consent issues are sensitive.

8. Mains Relevance

• GS-III — Infrastructure (Energy); Environment; Disaster Management (floods).
• GS-II — Centre-State relations (host-state benefits, JV model); Government policies for NE.
• Possible question stems:
• "Hydropower is central to India's clean-energy transition but politically and ecologically contested in the Eastern Himalaya. Discuss with reference to recent Arunachal projects."
• "Examine the role of flood moderation as a co-benefit in large hydro projects of the Brahmaputra basin."
• "Critically assess the JV / BOOT model adopted for hydro projects revived under central PSUs since 2023."

10. Common Errors / Trap Areas

• Wrong river: Kamala is a tributary of the Subansiri, not directly of the Brahmaputra; not to be confused with the Kamla river of Bihar/Nepal (Mithila) [2].
• Wrong districts: Project spans three districts — Kamle, Kra Daadi, Kurung Kumey — not just Kamle.
• Wrong PSU split: NHPC holds 74% (not 50:50) with GoAP [2].
• Wrong approving body: It is CCEA, not the Union Cabinet proper or CCS.
• Confusing with Kalai-II (1200 MW, Anjaw) approved the same day — different river, district, PSU [1].
