Kadyrinskaya hydropower plant modernisation


Located in the Tashkent region, Uzbekistan, the Kadyrinskaya Hydropower Plant (Kadyrinskaya HPP-3) forms part of the Chirchik-Bozsuv cascade of 19 hydropower plants. The total capacity of the run of river hydropower plants is 1,275.4MW. It was originally commissioned with a capacity of 13.2MW and during 85 years of operation, four of its hydroelectric units declined in efficiency and required major repair.

Following a Presidential Decree in May 2017, the modernisation project was launched in December 2017 with the following objectives: Bring the plant’s level of operations up to a modern standard; improve the reliability and safety of operations; increase electricity generation; automate more processes; and extend the life of equipment. In the third quarter of this year, HPPs have implemented the national and international standard ISO:50001 ‘Energy Efficiency’. In the future, the issue of introducing safety and health regulation standards is being considered.

During the three-year project – concluding in 2020 – a number of sequential activities were carried out, including construction and installation work; assembly and installation of technical equipment; constructing a complete set of spare parts; and landscaping of the site and nearby territory. The project included construction of a new hydroelectric power station building with two units. Other items constructed included a water intake, two pressure pipelines and a discharge channel which was connected to the existing diversion canal. To maximise the life-cycle of a new plant, the selection of equipment to be installed is considered prior to the start of modernisation by arranging and conducting a technical audit of equipment at HPPs. These projects, carried out by contractors on a turnkey basis, are not considered by HPPs but recommendations are given for inclusion in the contract.

The main hydraulic equipment was produced by Dongfang Electric International Corporation, the Chinese state-owned manufacturer of power generating equipment, with assembly and installation executed by highly qualified international and Uzbek specialists.

Design work streams executed by specialists from JSC Hydroproject, technical equipment produced and delivered by JSC Suvsanoatmash and JSC Uzbekgidroenergostroy assisted with the construction of individual elements.
