The first of the plant’s four 70MW units will come online next month, with the other three scheduled to start running by September.

The run-of-the-river project features a 56m high dam, a 750m long diversion tunnel and a 5.3km long head race tunnel leading to an underground power house. A 437m long tail race tunnel will take the water back to the river.

The Dhauliganga is owned by the state-run National Hydroelectric Power Corporation (NHPC), the country’s largest hydro power utility, and is located on the Dhauliganga river, in the Pithoragarh district on the border of India and Nepal.
