Etalin Hydroelectric Project Latest News

The Project Affected Peoples Forum (PAPF) in Arunachal Pradesh has recently called on NHPC Ltd to reinstate all local workers who were previously engaged in the Etalin Hydroelectric Project (HEP). This appeal follows the Centre's decision to transfer the project from SJVN Limited to NHPC.

About the Etalin Hydroelectric Project

The Etalin Hydroelectric Project is a significant 3,097 MW hydropower initiative planned on the Dri and Talo rivers, which are tributaries of the Dibang River in Arunachal Pradesh's Dibang Valley. This project stands as one of the largest hydropower ventures in India concerning installed capacity.

The project aims to utilize a combination of two run-of-the-river schemes and is being developed by NHPC Limited (previously known as the National Hydroelectric Power Corporation). It will incorporate two concrete gravity dams—one on the Dri River and another on the Talo (Tangon) River. An underground powerhouse is planned to be situated near their confluence, close to Etalin village.

Projected Energy Generation

The Etalin Hydroelectric Project is expected to generate approximately 12,752 GWh of electricity annually. This significant output will contribute to India's renewable energy goals and help meet the growing energy demands.

Environmental and Social Considerations

The project area is located within the “richest bio-geographical province of the Himalayan zone” and is recognized as “one of the mega biodiversity hotspots of the world.” This rich biodiversity is home to various species, making environmental conservation a critical concern.

Moreover, the region is predominantly inhabited by indigenous populations, including the Idu-Mishmi tribes. The involvement of local communities in project planning and execution is essential to ensure that their rights and livelihoods are protected.
