Concrete pour has commenced for construction of the core dam at the Rogun hydropower project in Tajikistan, WeBuild has announced, marking a major milestone for what will be the world’s highest dam once complete.

Webuild CEO Pietro Salini joined Tajikistan President Emomali Rahmon at a ceremony to celebrate this achievement on 15 July.  

Located in the upper reaches of the Vakhsh River in the Pamir Mountains west of the Himalayas, the 3600MW Rogun hydropower project will double the Central Asian country’s production capacity once complete. The project will feature the highest dam in the world with a dam crest at 1300 m asl, breaking the record held by the Nurek Dam, also in Tajikistan. At 335m, Rogun will also be the tallest dam in the world.

Rogun already has two turbines that are producing electricity. Unit 5 and 6 each have a capacity of 600MW. The early generation has allowed Tajikistan to reduce power shortages suffered during the winter months, and export part of the electricity produced to neighbouring countries.

Commissioned by OJSC Rogun Hydropower Plant, Webuild is responsible for the main civil works in the construction of the rockfill dam with a loam core.
