Climate Risks to Hydropower in Uttarakhand

Recent reports highlight the increasing vulnerability of hydropower projects in Uttarakhand due to climate-related extreme weather events. The Chamoli disaster in 2021 and the Teesta III incident in 2023 exemplify the severe impact of these events. These occurrences have not only caused loss of life but also led to substantial economic setbacks. The financial implications of the Chamoli disaster alone are estimated at around Rs 1,625 crore, with debris removal costs projected at Rs 3,400 crore.

Impact of Climate Change on Hydropower Projects

Climate change poses an important threat to hydropower projects. The Himalayan region is experiencing more frequent and intense weather events. These disruptions can lead to severe damage to infrastructure. Reports indicate that many hydropower projects are located in high-risk areas prone to seismic and climatic disasters.

Current Hydropower Landscape in Uttarakhand

Uttarakhand is home to numerous hydropower projects. Currently, there are 81 large projects planned, with an investment of around Rs 70,000 crore. However, many of these projects are situated in areas identified as high-risk. The potential for future disasters raises concerns about the viability of these investments.

Assessment of Vulnerable Areas

Certain regions in Uttarakhand are more susceptible to disasters. The Uttarakhand State Disaster Management Authority has identified areas such as Haridwar and Rishikesh as particularly at risk. The Manglaur Basin is brought into light for flood risks, while the Pithoragarh-Bageshwar basin is noted for landslide susceptibility.

Recommendations for Risk Mitigation

To address these challenges, experts recommend avoiding new hydropower projects in high-risk zones. Implementing multi-hazard early warning systems is crucial for timely disaster response. Furthermore, adopting climate-resilient standards for existing projects can enhance their ability to withstand extreme weather events.

Need for Updated Data and Monitoring

Outdated climate data exacerbates the risks faced by hydropower projects. Continuous monitoring of climatic conditions is essential. This will help in understanding the evolving risks and ensuring the safety and sustainability of hydropower infrastructure.

Future Outlook

The future of hydropower in Uttarakhand hinges on proactive measures. As climate change accelerates, the focus must shift towards sustainable practices and infrastructure resilience. The implementation of robust risk management strategies will be vital for safeguarding both the environment and the economy.
