Webuild has achieved what it called a major milestone at the 3.6GW Rogun hydropower project in Tajikistan, which is set to double the country’s generating capacity, with the start of the concrete pour for the core dam.
Tajikistan President Emomali Rahmon joined Webuild chief executive Pietro Salini for a ceremony to mark the occasion.
Located in the upper reaches of the Vakhsh River in the Pamir Mountains west of the Himalayas, Rogun will be the highest dam in the world with a dam crest at 1,300 metres above sea level, breaking the record held by the Nurek Dam, also in Tajikistan.
At 335 metres in height, Rogun will also be the tallest dam in the world.
Webuild is responsible for the main civil works in the construction of the rockfill dam with a loam core.
Located about 90 kilometres from the capital Dushanbe, the entire project includes tunnel works and construction of the powerhouse and electromechanical works. Around 2,000 people are working on it, most of them Tajik nationals, Webuild said in a press release.
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 in winter and to export some electricity.
Once all six turbines have been installed, each with a capacity of 600MW, Rogun will have a total installed capacity of three nuclear power plants, making it the most powerful hydroelectric station in Central Asia, Webuild said.
