2022: Accidents & Damages related to Hydro projects in India

In this annual review, SANDRP compiles the hydro power related accidents, disasters and damages in North West and North East Himalayan states during 2022. It also covers relevant reports revealing gradual decline in power generation by hydro power projects amid growing concerns over physical and financial viabilities of new projects. There are also reports highlighting the looming climatic and geological threats over these projects. It is good to see that taking lessons from Chamoli disaster in Feb. 2021, NDMA has officially asked central govt not to rely on hydro power.

In previous parts of yearend roundups, we have covered (1) Dam induced floods & damages, (2) Fly ash dam breach incidents, (3) Impact of floods on Polavaram project, (4) People’s resistance against dams and hydro projects. Please see links for reports tracking hydro power projects related accidents and disasters in 2021 and 2020.

Over the course of past two years, series of disasters and accidents have taken place at construction site of the controversial 2000 MW Lower Subansiri Hydro Power Project resulting in damages to project structure and death of construction workers thus raising questions over its safety and sustainability. Since 2005-06, the largest ever under-construction hydropower project is being developed by NHPLC Ltd (formerly known as the National Hydro Power Corporation Limited), a central government company in geologically fragile, seismically vulnerable and biodiversity rich area in the face of pending judicial case[i] and very strong opposition from people across the Assam.

The latest disaster in form of a massive landslide affected the project site on October 12, 2022 further delaying the repair works which were being carried to recover damages caused by the flash floods, landslips at dam site in last week of September 2022.

Uttarakhand Cloud Burst 2022: Road Debris, Drainage Encroachment Magnify Destruction

For the past many years, cloud bursts have been emerging as a significant and reoccurring disaster in Himalayan region. The highly localized, intensive rainfall spell, consequent flash floods and landslides have been taking a heavy toll on human and infrastructure apart from impacting the landscape. SANDRP has been documenting such incidents particularly in North West Himalayan states of Jammu & Kashmir, Himachal Pradesh and Uttarakhand. This first part of 2022 tracks the ‘cloud burst’ incidents reported in Uttarakhand before and during SW monsoon 2022. SANDRP’s previous compilation and analysis on the issue for Uttarakhand can be seen here 2018[i], 2019[ii], 2020[iii], May 2021[iv] and 2021[v].

Hydropower projects are force multipliers when cloud burst happens close to them. In 2021 at least 11 HEPs (4 each in Uttarakhand & Himachal, 2 in J&K and 1 in Ladakh) projects had faced cloud burst induced deluge and damages in lesser or greater degree.

In the latest such incident, the 100 MW Malana II Hydro Electric Project (HEP) in Parbati Valley in Himachal Pradesh has been affected by flash floods following cloud burst in Malana village area in early hours of July 6, 2022. The operational project is located on Malana stream, a tributary of Parbati river in Kullu district. This incident seemingly coincided with another devastating cloud burst near Choj village in Parvati valley located about 15 km south west from Malana.
