Environmental, Social and Economic Consequences of Hydroelectric Power Plant Dam Failures in India

Hydropower is a key pillar of India’s clean energy plans. But the dams of these plants are located in valleys where thousands of people live and any damage to them could easily turn into a large-scale disaster. Taking three documented events like 1979 Machhu Dam failure in Gujarat, 2021 Rishiganga Tapovan disaster in Uttarakhand and 2023 Teesta dam disaster in Sikkim. In this paper we study the implications of damage to an Indian hydroelectric dam. The paper traces the evolution of one structural failure and the cascade of effects that followed: the loss of life, damage to infrastructure, environmental degradation, disrupted communities, gaps in power supply and in at least one instance flooding across an international border. Then it zooms out to ask why these kinds of failures keep happening, pointing fingers at climatedriven glacial hazards, spillways designed for the wrong flood, gaps in environmental oversight and aging infrastructure. The paper ends with practical recommendations for improving early warning systems, revising standards for design floods, and strengthening regulatory follow-up to lessen the probability and severity of future dam disasters in India.
