The Rogun Dam in Tajikistan, under construction by Webuild, will soon reach an elevation of 1110m above sea level, a milestone that will allow the reservoir level to rise further and increase electricity output. Once completed, Rogun will be the tallest dam in the world at 335m.
President Emomalī Rahmon visited the site with Prime Minister Qohir Rasulzoda, ministers, government officials and representatives of OJSC Rogun HPP, the state company overseeing the project. The government has presented the project as essential to addressing power shortages, which affect about 70% of the population during winter months.
When finished, the hydroelectric plant will have an installed capacity of 3600MW, which is comparable to three nuclear reactors. It is expected to supply electricity to around 10 million people, doubling Tajikistan’s power generation capacity.
Construction advanced by 100m over the past year, with about 13 million cubic metres of embankment material placed in the dam structure. Of this, 3.5 million cubic metres were loam used for the dam’s impermeable core. More than 180,000m of foundation and abutment injections have also been completed to consolidate the structure and strengthen tunnels.
The Rogun site faces harsh environmental conditions, including extreme winter cold and summer storms. Webuild, which has built more than 300 dams and hydroelectric projects worldwide, is also completing other large-scale hydropower works, including the Grand Ethiopian Renaissance Dam, scheduled to be inaugurated in September, and Snowy 2.0 in Australia.
