International technology Group ANDRITZ said it received an order from Barqi Tojik energy holding for rehabilitation and modernization of the entire electro-mechanical equipment, including the inspection and repair of nine penstocks, for the existing Nurek hydropower plant.
With the current installed capacity of 3,000 MW, Nurek is the largest hydropower plant in Central Asia and covers more than 70% of the national electrical energy demand. The project is funded by the World Bank. The contract value for ANDRITZ amounts to slightly more than 120 million euros.
The objectives of the Nurek Hydropower Rehabilitation Project for Tajikistan are to rehabilitate and restore the generating capacity of nine power generating units at Nurek hydropower plant, improve their efficiency, and enhance the safety of the Nurek dam.
After modernization, the installed capacity of the generating units will be increased by about 12%.
The design of the new units takes account of the plant’s annual storage operations and will, therefore, be suitable for operation with a wide range of heads. Together with the Rogun hydropower plant, which is under construction and located upstream of the Nurek reservoir, this project will optimize water storage management on the Vaksh river cascade, ensuring a significant increase in electrical energy production by the Nurek hydropower station as well as meeting the changing grid demands. The contract also stipulates that environmental conservation measures and water management requirements must be incorporated.
