Proposed Siang Dam in Arunachal Pradesh
Summary
- The Arunachal Pradesh government has approved a proposal to construct a hydro‑electric dam on the Siang River, the upstream stretch of the Brahmaputra.
- The project is expected to harness the river's high hydraulic head to generate several thousand megawatts of power, contributing to the North‑East's energy deficit.
- Environmental groups have raised concerns over potential displacement of indigenous communities, loss of biodiversity, and downstream flow reduction affecting Assam and Bangladesh.
- The central Ministry of Power and the North Eastern Electric Power Corporation (NEEPCO) are likely to oversee funding and technical implementation.
Key Facts
- · Siang River is the upstream name of the Brahmaputra in Arunachal Pradesh.
- · The dam is part of the government's push for renewable hydro‑electric capacity in the North‑East.
- · Projected installed capacity is in the range of 2,500–3,000 MW.
- · The project could affect downstream water availability for Assam and Bangladesh.
- · Environmental clearances are pending amid forest and wildlife concerns.
Why it matters
The Siang dam illustrates the trade‑off between harnessing renewable hydro‑electric power to meet India's growing energy needs and safeguarding fragile Himalayan ecosystems and downstream water security, a recurring theme in national policy and interstate water management.
