The works consist of the design and construction of a Roller Compacted Concrete (RCC) dam and an open-air power plant with 10 Francis turbines with a total installed power of 1,870 MW and an expected energy output of 6,500 GWh per year.
The project also involves three diversion tunnels and two twin pumping tunnels, two intake structures, two horizontal tunnels, four vertical wells and two distributors.
