Etalin Hydroelectric Project

April 17, 2025

The government has allocated Rs 269.97 crore for the Etalin Hydroelectric Project aimed at harnessing the hydropower potential of the Dibang Valley. It is expected to play a key role in the sustainable growth of the region.

Project Details

The Etalin Hydroelectric Project is designed to generate 3097 MW of power.
It is one of the largest hydropower projects in India. The project is located in the Dibang Valley, which is rich in water resources.
The initiative aims to contribute to the country’s energy needs while promoting economic development in Arunachal Pradesh.

Community Involvement

Local communities, particularly the Mishmi tribe, play important role in the project’s success. Their cooperation is essential for the project’s implementation. The government acknowledges their importance in leveraging the state’s hydropower potential. Engaging with local populations ensures that their voices are heard in decision-making.

Significance of Dir and Tangon Rivers

The Dir and Tangon rivers are vital tributaries of the Dibang River. They provide essential water resources for irrigation and hydropower generation. These rivers support diverse ecosystems and serve as major tourist attractions due to their scenic beauty. Their ecological health is critical for maintaining local biodiversity.

Environmental Concerns

The Etalin project raises environmental concerns. The construction of a large dam will inundate vast forest areas and wildlife habitats. This could lead to the displacement of local communities, particularly indigenous groups dependent on the river for their livelihoods. The project’s impact on the river ecosystem may disrupt fish migration patterns, affecting local fisheries.

Risks

Experts have raised concerns about geological and seismic risks associated with the project. Such risks could undermine both the project’s viability and the region’s biodiversity.

Regulatory Framework

The Forest Advisory Committee (FAC) plays a very important role in assessing projects like Etalin. Constituted under the Forest (Conservation) Act of 1980, the FAC advises the government on forest land diversion for non-forest uses. Its recommendations are crucial for ensuring that environmental considerations are taken into account.

Future Directions

A community-led approach is essential for the project’s success. Local populations should be actively involved in decision-making processes. Demarcating ecologically sensitive areas is necessary to prevent biodiversity loss. Comprehensive Environmental Impact Assessments (EIA) must be conducted to evaluate the project’s potential effects on the local environment.
