The work involved the construction of a dam 190 m high and 300 m long, an underground powerhouse which houses three turbines with a total installed power of 820 MW, the construction of two diversion tunnels approximately 870 metres long and the construction of the access roads and tunnels system to the underground powerhouse.
The plant, the fourth largest in the country, supplies about 10% of the country's annual energy requirement, playing an important role in generating the annual average of energy (5,056 GWh per year).
