The project involves the construction of a main dam in loose materials with a concrete surface (CFRD) 150 m high and 635 m long, with the spillway located on the left side of the dam body, controlled by four sluices and with a “trampoline” drainage channel for energy dissipation.
The project comprises also a secondary dam 66 m high and 410 m long.
More than 2,300 people worked on the maxi hydroelectric project that was completed on time to meet the contractual deadline. Among other things, they built four tunnels 10 metres in diameter and 400 metres long each, excavated 5 million cubic metres, filled in 13 million cubic metres and built concrete works totalling 250 thousand cubic metres. Some of the most advanced solutions to protect the environment and to redevelop an area of large agricultural development were implemented at the plant.
