Construction commenced during the Soviet period in the 1980s, but halted in the beginning of the 1990s due to lack of financing when the station was about 20% complete.
[1] Dissolution of the Soviet Union, the resulting halt of financing, as well as the Civil War in Tajikistan interrupted the construction for over a decade.
[3] The first unit entered service ahead of schedule on 20 January 2008 during the unusually harsh winter, with temperatures dipping below −20 °C (−4 °F), which put the Tajik energy system on the brink of collapse.
[5] On 31 July 2009, the plant was officially commissioned, with the presidents of Russia and Tajikistan Dmitry Medvedev and Emomalii Rahmon participating in the event.
[7] The Sangtuda 1 Hydroelectric Power Plant is located on the Vakhsh River in Khatlon region, 160 kilometres (99 mi) south of Dushanbe.
[12] There are plans to construct a high-voltage power transmission line to Kyrgyzstan, Iran, Afghanistan, and Pakistan for the electricity export.
[2] Some of Tajikistan's neighbours, especially Uzbekistan, are concerned that construction of large hydroelectric plants within the headwaters of the region's rivers will result in shortages of water downstream.
Rail traffic blockade by Uzbekistan had delayed construction of transmission lines from the plant to Afghanistan and Kyrgyzstan.
