The dam supplies water to five turbine-generators in two different powerhouses for an installed capacity of 1,500 megawatts (2,000,000 hp) while it can also control a design 19,100 cubic metres per second (670,000 cu ft/s) flood.

[1] The dam submerged an area of 17.67 square kilometres (6.82 sq mi), displacing about 10,300 people.

[2] In March 2000, a feasibility study report on a pumped-storage capability for the dam was approved.

In August 2002, construction started on installing two 150 MW reversible pump generators and by July 2006, they were operational.

The first station to be constructed is located underground and contains 3 x 300 MW Francis turbine generators while the second, located on the left bank slightly downstream contains 2 x 300 MW Francis turbine generators.
