Rogun Dam Reaches Full Height
- Rogun Dam on the Vakhsh River, Tajikistan, is planned at 335 m high with a 13.3 km3 reservoir and six 600 MW turbines (3,600 MW planned, 240 MW installed), about 17.1 TWh a year; contractor Webuild[1][2][3]
- History: begun 1976, abandoned 1993, restarted 2016 with Salini Impregilo chosen for $3.9 billion; first unit commissioned November 2018, second September 2019; main core concrete began mid-July 2022[1]
- Webuild's August 2025 note says the dam is nearing 1,110 m above sea level, having risen up to 100 m in a year and placed about 13 million m3 of embankment material[3]
- On completion it is to equal three nuclear reactors of capacity, serve about 10 million people and double Tajikistan's energy production[3]
- Al Jazeera (29 May 2026) calls it the "$5bn Rogun project" and "Project of the Century", with a Webuild engineer confirming the 335 m height[2]
- Wikipedia lists the opening date as "2018-2029" and the cost as US$2-5 billion[1]
