Tato-I HEP Project is a run-of-the-river hydropower project in the State of Arunachal Pradesh, in Northeastern India.
With an installed capacity of 186 MW, it is the second-largest in a cascade of three projects totaling 571 MW on the Yarjep River. Velcan has been developing the Tato-I Project since 2007. At the time, the installed capacity was expected to be approximately 70 MW. However, the abundance of water as well as Velcan’s proprietary engineering work over a number of years prompted the capacity to be revised to 240 MW.
In April 2015, Indian Ministry of Environment, Forests and Climate Change has approved the Environmental Clearance the Tato-I Project (as well as for the Heo (240 MW) and the Pauk (145MW) Projects).
This milestone was achieved after 7 years of diligent environmental studies and field work with the local population and stakeholders. The EIA (Environment Impact Assessment) and EMP (Environment Management Plan) studies were submitted in June 2014 following successful public hearings held between August and November 2013 for the 3 projects of the cascade. These involved more than five hundred people from villages nearby. Subsequently, the Expert Appraisal Committee (EAC), an independent, multidisciplinary body of experts, held appraisal meetings in July and August of 2014 and recommended that the Ministry grant the Final Environmental Clearance. The minor nature and small number of environmental issues raised during the committee meetings confirmed, on one hand, that the projects are environmentally friendly, whereas they will, on the other hand, have very significant positive social and economic impact on the region.
As per applicable regulations, the Environmental Clearances will be formally issued after Stage I Forest Clearances, which are currently under progress.
On 10th May 2013 Velcan Energy successfully filed with the Indian Central Electricity Authority (CEA) the Detailed Project Report (DPR) for the Project.
The DPR is the consolidated aggregate of more than 15 separate detailed studies including items such as geology, topography, hydrology, civil design and electro-mechanical engineering, cost analysis and financing. The DPR will be the basis for the issuance of the Techno-Economic Clearance for the Project by the CEA. This clearance will then allow Velcan Energy to begin negotiations for a Power Purchase Agreement (PPA) with prospective clients and seek financing with various interested parties and banks.
The concession period is set at 40 years after commissioning.
