NHPC has confirmed the recovery of 13 bodies following a gas explosion at its Teesta Stage-VI hydropower project in Sikkim. Rescue operations continue for remaining personnel while the company coordinates with local agencies and disaster response teams.
Detailed Coverage
NHPC Limited has reported a tragic accident at its under-construction Teesta Stage-VI Hydroelectric Project located in South Sikkim. According to the company's official communications, a suspected methane gas explosion occurred on July 20 within the project's Head Race Tunnel, trapping 25 personnel inside. As of July 22, 2026, 13 bodies have been successfully recovered from the site.
Status of Rescue and Coordination
The site remains under active rescue operations as agencies work to reach the remaining trapped individuals. The efforts involve multi-agency coordination between the local District Administration, the National Disaster Response Force (NDRF), the State Disaster Response Force (SDRF), and the project contractor, Patel Engineering Limited. NHPC management has confirmed their senior leadership is currently on the ground to oversee the evacuation and support the ongoing search mission.
Impact and Company Response
The Teesta Stage-VI project is a significant infrastructure undertaking for NHPC, aimed at increasing hydropower capacity in the region. The sudden nature of the methane burst and the subsequent toxic gas release have halted construction activities in the affected tunnel section. In response to the incident, the company has announced an ex-gratia payment of ₹5 lakhs to the families of each deceased individual.
Investors may note that incidents of this nature often lead to temporary work stoppages and increased scrutiny regarding safety protocols and project timelines. While the immediate financial impact of this specific accident is being evaluated by the company, investors often look to project updates, insurance coverage for construction accidents, and potential regulatory reviews as key monitorables in the coming weeks. The company's focus remains on the completion of the rescue operation and the subsequent safety assessment of the tunnel structure, which will determine the timeline for the resumption of construction work.
