Rogun Dam reaches 1,110-metre milestone as Webuild drives energy transformation in Tajikistan and Central Asia

(IN BRIEF) Webuild’s construction of the Rogun Dam in Tajikistan has reached a crucial stage, with the dam’s crest approaching 1,110 metres above sea level. President Emomalī Rahmon visited the site with senior officials to highlight the project’s importance in doubling the nation’s energy production and securing power for around 10 million people. Standing 335 metres tall upon completion, Rogun will be the world’s tallest dam and a cornerstone of energy stability in Central Asia, where much of the population endures winter blackouts. The project has advanced by 100 metres in the past year, with 13 million cubic metres of embankment material placed and extensive consolidation works completed. Webuild emphasised the scale of the challenge, with construction taking place in extreme mountain conditions, while also pointing to its track record of more than 300 global hydroelectric projects. As Rogun nears its next stages, Webuild is preparing to inaugurate the Grand Ethiopian Renaissance Dam in September, further consolidating its position as the global leader in water infrastructure.

(PRESS RELEASE) MILAN, 29-Aug-2025 — /EuropaWire/ — The Rogun Dam in Tajikistan, under construction by Webuild, has reached a new technical milestone as it approaches an elevation of 1,110 metres above sea level — a key step that will allow the reservoir to rise further and significantly boost energy generation. President Emomalī Rahmon, accompanied by Prime Minister Qohir Rasulzoda, ministers, government officials, and representatives of client OJSC Rogun HPP, visited the site to underline the project’s strategic role for Tajikistan and the wider Central Asian region.

When completed, Rogun will be the tallest dam in the world at 335 metres, with an installed capacity equivalent to three nuclear reactors. It will supply electricity to an estimated 10 million people, doubling Tajikistan’s current energy output and helping to stabilise power supply across the region. The project is especially critical in a country where nearly 70% of the population faces electricity shortages during winter.

The past year alone has seen rapid progress, with the dam body rising by around 100 metres. Approximately 13 million cubic metres of embankment material have been placed, including 3.5 million cubic metres of loam forming the dam’s impermeable core. To strengthen the foundation and abutments, more than 180,000 linear metres of injection works have been completed, alongside consolidation and sealing interventions in key tunnels.

The Rogun site showcases engineering excellence under extreme conditions, from severe winter cold to intense summer storms, posing formidable logistical and technical challenges. With more than 300 dams and hydroelectric plants built worldwide, Webuild brings unmatched experience to this project, further solidifying its position as a global leader in water infrastructure.

As Rogun advances, Webuild is also preparing to celebrate the inauguration of another landmark achievement: the Grand Ethiopian Renaissance Dam, Africa’s largest dam, scheduled to open in September. Alongside Rogun and Ethiopia’s GERD, the Group is delivering Snowy 2.0, Australia’s largest hydroelectric initiative, underscoring its commitment to global sustainable energy and water security.

ENR Engineering News-Record recently reaffirmed Webuild’s leadership by ranking it first in the Top 250 International Contractors for water projects — a position held for more than a decade — reflecting the Group’s expertise in building resilient infrastructure to address worldwide water and energy challenges.
