The central government has granted environmental clearance to the Oju hydroelectric project in Arunachal Pradesh’s Upper Subansiri district, paving the way for the construction of one of India’s largest hydropower ventures in a geologically sensitive and strategically important region bordering China.

The project, to be developed by Oju Subansiri Hydro Power Corporation Pvt Ltd, envisages generating 2,220 megawatts of electricity through a run-of-the-river scheme with daily peaking capability.

It involves a 100-metre-high concrete gravity dam, a 14.12 km headrace tunnel and an underground powerhouse complex. With an estimated cost of “over %24,942 crore, the dam is expected to produce 8,402 million units of electricity annual-

ly, according to the minutes of the meeting of the environment ministry’s Expert Appraisal Committee held September 12.

The Oju project is the largest in a series of dams proposed on the Subansiri River, often described as the lifeline of Assam, and has been in the pipeline for nearly two decades. It has stirred concerns over its social and environmental consequences.
