Arun-III Hydroelectric Project: SJVN Completes 11.8 KM Head Race Tunnel in Nepal

June 4, 2024 – Sankhuwasabha, Nepal

Sutlej Jal Vidyut Nigam (SJVN), a prominent Indian public sector undertaking, has successfully achieved a significant milestone in the construction of the Arun-III Hydroelectric Project. The company has completed the excavation of an 11.837 kilometer main head race tunnel for the project, which is expected to generate 900 megawatts (MW) of power. This landmark achievement marks a crucial step towards realizing Nepal’s renewable energy potential.

The Arun-III project, situated in the Sankhuwasabha district of Nepal, is poised to play a vital role in the region’s energy landscape. The project not only aims to enhance Nepal’s energy security but also seeks to facilitate cross-border electricity trade between India and Nepal, further strengthening bilateral ties.

The successful excavation of the head race tunnel was accomplished using ORICA explosives and accessories, which were the preferred choice of the contractors for this phase of construction. The advanced technology and efficient blasting techniques employed have minimized environmental impact while ensuring the structural integrity of the tunnel.

In addition to its energy generation capabilities, the Arun-III project is expected to create numerous job opportunities in the region, contributing to local economic development. The project will also focus on sustainable practices, including the implementation of environmental management plans to mitigate any potential ecological impacts.

The Arun-III Hydroelectric Project is part of a broader strategy to tap into Nepal’s abundant hydropower resources, which are estimated to exceed 80,000 MW. With the completion of the head race tunnel, SJVN is on track to meet its project timelines, with further phases of construction expected to progress smoothly.

As Nepal continues to develop its hydropower infrastructure, projects like Arun-III are crucial in addressing energy demands, promoting sustainability, and enhancing regional cooperation in the energy sector. The successful collaboration between Indian and Nepali stakeholders in this project serves as a model for future initiatives aimed at harnessing the region’s renewable energy potential.

With the groundwork laid, SJVN remains committed to completing the Arun-III Hydroelectric Project on schedule, contributing to a greener, more sustainable future for Nepal and the surrounding region.
