Nurek Hydropower Rehabilitation Project Phase I

active

The objectives of the First Phase of Nurek Hydropower Rehabilitation Project for Tajikistan are to rehabilitate and restore the generating capacity of three power generating units of Nurek hydropower plant, improve their efficiency, and strengthen the safety of the Nurek dam. There are three components to the project, the first component being rehabilitation of the three generating units, the key infrastructural components of the plant, and replacement of autotransformers. This component will consist of two sub-components: replacement and refurbishment of mechanical, electrical, and electromechanical equipment; and replacement of six autotransformers. The second component is the enhancement of dam safety. This component will finance activities to improve the safety of the operation of the Nurek HPP. The cost estimate for this component includes a provision for the possible mitigation measures that may be required. The cost of this component was estimated taking into account the maximum scope of activities, which may need to be implemented based on the results from ongoing seismic hazard assessment work. Therefore, the cost estimate includes a margin sufficient to implement all of the dam safety enhancement related activities, which will be required. Finally, the third component is the technical assistance. This component will support implementation of the project and strengthen the institutional capacity of BT by supporting the following: Project management consultant (PMC) to assist with the review of designs, bidding, quality control and construction supervision of the project. BT has already signed the US$5.2 million equivalent contract with PMC; (b) Panel of Experts (PoE) on matters related to dam safety and other critical aspects of the project; and (c) Technical and other engineering studies, which may be required during project implementation.
