What is the issue with hydropower projects on the Teesta River?
- Frequent Natural Disasters: The Teesta river’s hydropower projects are vulnerable to natural disasters. For example, the October 2023 glacier outburst destroyed the Teesta-3 dam, which reduced its power output by 90%.
- Construction Concerns: Developers of Teesta-3 opted for a cheaper concrete-faced rock fill dam instead of a more durable concrete gravity dam, leading to its complete destruction.
- Environmental Risks: The river’s challenging terrain makes the projects susceptible to environmental risks, which have often been underestimated.
- Limited Project Development: Out of 47 proposed hydropower projects on the Teesta, only five are operational, with 16 under consideration, showing the difficulty in balancing development with environmental safety.
- Need for Better Assessments: Accurate environmental impact assessments are crucial to ensure public trust and project sustainability.
