The Tato II project is one of the largest hydro investment in Arunachal Pradesh.
Located in the West Siang district on Siyom river, the Tato II project would consist of four units of 175 MW each.
The project is set to generate annual design energy of over 3,000 MU with an annual load factor of over 50 per cent, which is one of the highest amongst hydro projects in the country.
Tato is designed to operate as a peak power station, and a power purchase agreement (PPA) has been signed with the BSES Rajdhani Power and BSES Yamuna Power for sale of power to the power-starved Delhi region.
A subsidiary of Reliance Power, the Tato Hydro Power Pvt Ltd came into being to implement a hydroelectric power project in Arunachal Pradesh.
The Tato II project envisages an estimated investment of Rs 6,000 crore and is expected to be commissioned within six years from zero date.
The levelised tariff for the project is expected to be competitive due to the high plant load factor and run of the river structure of the project.
Levelised tariff in the power sector essentially refers to the average fixed and variable tariff over the entire term of the PPA.
Hydro power projects
The Anil Dhirubhai Ambani Group subsidiary is developing 4,620 MW of hydroelectric power capacities at seven locations.
The company has added hydroelectric power plants into its portfolio to take benefit of the immense hydro potential in the country.
An official said hydroelectric power projects typically take 9-10 years of implementation.
The company aims to implement these projects at a faster pace and is planning to commission these projects in a period of 5-6 years.
