Sangtuda 2 Hydroelectric Power Plant is a Tajik hydroelectric power plant, currently being built on the Vakhsh River.
Construction commenced during the Soviet period in the 1980s, but halted in the beginning of the 1990s due to lack of financing. In 1995, Iran expressed interest in helping to finish the project, but an agreement was not signed until 2005. Building work re-started on 20 December 2006.[1][2]
The first unit was inaugurated on 6 September 2011 by presidents Emomalii Rahmon and Mahmoud Ahmadinejad.[3]
The power plant is built and operated Iranian company Sangob.[4] The main contractor was Omran Maroon.[5] It operates simultaneously with Sangtuda 1 Hydroelectric Power Plant. It uses gates of Nurek reservoir.[4]

The run-of-river type power plant consist of two units able to produce 1 TWh of electricity a year. The generating equipment is manufactured in China.[6][7]
Revenues during first 12 years would be paid to Iran - and after that, ownership would be transferred to Tajikistan.[2]
