Subansiri Dam - The largest hydroelectric project in India

 

Subansiri Dam - India's largest hydroelectric project

 

The Subansiri Lower Dam, officially named as Subansiri Lower Hydroelectric Project is an under-construction gravity dam on the Subansiri River in North Eastern India. It is located 2.3 km upstream of Subansiri River on Arunachal Pradesh. This Project is expected to supply 2,000 MW of power after completion & will be the largest hydroelectric project in India. 

Unexpected geological conditions at the dam site led to landslides and slower tunnel excavation. By November 2007, the river was successfully diverted and in April of the next year, the foundation was clear for construction. Before the foundation was fully prepared it was discovered that bedrock was reached 33 feet sooner than expected. This led to an alteration in the dam's design for stability.

The concrete gravity dam is designed to be 381 feet tall, measured from the river bed and 690 ft from foundation. Its length will be 932 ft and the dam will have a structural volume of 2,250,000 m³. The reservoir created by the dam will have a gross storage capacity of 1.37 km³, of which .44 km³ can be used for power generation or irrigation.
