, the resulting halt of financing, as well as the Civil War in Tajikistan interrupted the construction for over a decade. In 1996, the government set up a company for the construction of the power plant and issued public shares. However, the company did not start operating and was liquidated when a deal with Russia was signed.

In October 2004, an intergovernmental agreement was signed by Russia and Tajikistan to complete the project. In January 2005, Russia, Tajikistan and Iran

 signed a protocol according to which Russia would participate in construction of Sangtuda 1 and Iran in construction of Sangtuda 2 power plants. On 16 February 2005, a joint Russian-Tajik company Sangtudinskaya GES-1 was established. Construction resumed in April 2005.

The first unit entered service ahead of schedule on 20 January 2008 during the unusually harsh winter, with temperatures dipping below -20 °C, which put the Tajik energy system on the brink of collapse. The second and third units entered service on 1 July 2008, and 15 November 2008, respectively. The fourth and final unit was brought online on 15 May 2009. On 31 July 2009, the plant was officially commissioned, with the presidents of Russia and Tajikistan Dmitry Medvedev

Significance

Launching of the plant is a significant milestone in achieving energy independence for Tajikistan, as the country had experienced severe energy shortages ever since it acquired independence. The plant provides around 12% of Tajikistan's electricity output. The plant is the largest project within the Commonwealth of Independent States

, are concerned that construction of large hydroelectric plants within the headwaters of the region's rivers will result in shortages of water downstream. Withdrawal of Uzbekistan from the Central Asian unified power system cut also Tajikistan off from the system and blocked electricity export via Uzbek to southern Kazakhstan. Because of this, the plant can't utilize its full capacity. Rail traffic blockade by Uzbekistan had delayed construction of transmission lines from the plant to to Afghanistan and Kyrgyzstan.
