NHPC pledges Rs 5 lakh compensation to families after tragic Sikkim tunnel blast

On a quiet July morning, the under‑construction Head Race Tunnel (HRT) of the Teista Stage‑VI hydro‑electric project in South Sikkim turned into a scene of horror. An abrupt blast – officials say it was likely a methane gas ignition – caused the tunnel to cave in, trapping dozens of workers inside.

Rescue teams scrambled through the night. By the time the dust settled, the death toll had risen to at least 20, with a further five workers still unaccounted for. Out of the 25 men who were believed to be inside when the explosion struck, 13 bodies have been recovered so far, while the search for the remaining personnel continues around the clock.

The operation is a massive joint effort, involving the District Administration, the National and State Disaster Response Forces (NDRF, SDRF), NHPC’s own engineers, Patel Engineering Limited, and even the coal‑field units of Eastern and Western Coalfields. NHPC’s top management is on the ground, coordinating every move and keeping a watchful eye on the progress.

In a statement released later that day, the state‑run power utility said it would offer an ex‑gratia payment of Rs 5 lakh to the next‑of‑kin of each worker who lost their life in the tragedy. While money can never fill the void left by such a loss, the company said the gesture was meant to provide some immediate relief to grieving families.

“We express our profound grief over the tragic loss of lives and extend our deepest condolences to the bereaved families in this hour of grief,” NHPC wrote, adding that every possible effort was being made to locate and evacuate the remaining workers as quickly as possible.

The incident has reignited concerns about safety protocols in large‑scale hydro projects, especially those that involve tunnelling through geologically sensitive zones. Experts point out that methane pockets can build up in such environments, and proper ventilation and continuous monitoring are essential to prevent catastrophic explosions.

As the rescue operation presses on, the families of the victims and the broader community wait anxiously for news of any further recoveries. The incident stands as a stark reminder of the perils that construction workers face daily, and of the need for unwavering vigilance on every job site.
