A significant industrial accident occurred at a major hydropower construction site in northern India on Tuesday night, resulting in mass casualties when two monorail trains collided within an underground tunnel. The incident took place at the Pipalkoti hydropower project in Uttarakhand state, operated by Tehri Hydro Development Corp (THDC), a joint venture partially owned by NTPC Ltd.
According to Gaurav Kumar, the district’s chief administrative officer, the collision was triggered by catastrophic brake failure in one of the monorail vehicles. These transport systems are critical infrastructure at the construction site, primarily used for ferrying personnel and moving construction materials through the extensive tunnel network.
The collision resulted in 109 workers sustaining injuries, with medical officials reporting that most victims suffered minor trauma while four individuals sustained serious fractures. Emergency response teams were immediately deployed to the remote mountainous region to provide medical assistance and extract injured workers from the confined tunnel environment.
Despite the severity of the incident, Kumar confirmed that track clearance operations were completed promptly, with project managers anticipating a resumption of construction activities on Wednesday. The quick recovery highlights the project’s strategic importance to India’s energy infrastructure development.
This accident brings attention to India’s ambitious hydropower expansion program. Currently, hydropower constitutes approximately 51 gigawatts of the nation’s 505-gigawatt total installed capacity. Uttarakhand state, where this incident occurred, hosts more than ten operational hydropower facilities with approximately 2.0 gigawatts of combined capacity, alongside numerous projects under development.
