Naitwar Mori Hydro Power Station with a generation potential of 60 MW is located on River Tons, a major tributary of River Yamuna in Uttarkashi district of Uttarakhand State in North India. The project is designed as a standalone run of the river project. The entire project is on the right bank of river Tons stretching from Barrage site near village Naitwar and Power house complex near Bainol village. Naitwar Mori Hydro Power Station has the potential to generate 265.5 million units of electricity each year. A Memorandum of Understanding for execution of Naitwar Mori project was signed with the Government of Uttarakhand in November 21, 2005.
Hon’ble Union Minister of Power (Independent Charge) Sh. R K Singh and Hon’ble Chief Minister of Uttarakhand Sh. Trivender Singh Rawat laid the foundation stone of the Project at Mori on 30.03.2018.
All major works in 3 packages completed and both units of the project have been commissioned as per following details.
