[1][2] The power station has a 1,240-megawatt (1,660,000 hp) capacity and is supplied with water by a roller-compacted concrete gravity dam.

On the western portion of the dam, 15 sluice gates feed water from the reservoir into the power plant's intake channel.

The power station is 180 metres (590 ft) long and contains four 310 megawatts (420,000 hp) generators manufactured by Ansaldo Coemsa.

[4] 25% of the dam's $1 billion cost was involved in a resettlement program for the 1,000 families displace by the reservoir.

The program included building community centers, roads, churches along with paying for healthcare, environmental protection and land provisions.
