Tato-II Hydroelectric Project

The Tato-II Hydroelectric Project has been in the news recently with the Cabinet Committee on Economic Affairs (CCEA) approving an investment proposal of ₹8,146.21 crore for its construction in Arunachal Pradesh.

Key Details of the Tato-II Hydroelectric Project

• Capacity: The project will have an installed capacity of 700 MW.

• Location: The project is planned on the Siyom River (also known as the Siyom Basin) in Shi Yomi district, Arunachal Pradesh.

• Type: It is a run-of-river project, meaning that it will utilize the natural flow of the river to generate power without the need for large reservoirs.

• Hydro Reservoir Capacity: The reservoir is expected to have a capacity of 56 million cubic meters.

• Turbines: The project will feature four turbines, each with a 175 MW nameplate capacity.

• Energy Generation: The total energy generation expected from the project is approximately 2,738.06 million units of electricity.

Impact of the Project

• Power Supply for Arunachal Pradesh: The electricity generated will significantly improve the power supply in Arunachal Pradesh, which has faced challenges with energy access due to its geographical remoteness.

• National Grid Balance: In addition to serving the local needs, the power generated will contribute to balancing the national grid by providing additional supply during peak demand periods.

• Free Power for Arunachal Pradesh: The state will receive 12% of the generated power for free, in addition to 1% for the Local Area Development Fund (LADF), which can help in the socio-economic development of the area surrounding the project.

Implementation and Investment

• The project will be executed through a joint venture between the North Eastern Electric Power Corporation Ltd (NEEPCO) and the Government of Arunachal Pradesh.

• Cost: The total investment for the project stands at ₹8,146.21 crore, reflecting a major push for infrastructure development in the state.
