After the upgrade performed by Power Machines, power units five and six of the Syrdarya TPP, the largest power plant in Central Asia, have been successfully connected to the country's power system and put into operation.
As per the EPC contract signed between Power Machines and Syrdarya TPP in accordance with the Order of the President of the Republic of Uzbekistan "On measures for stage upgrade of the Syrdarya TPP power units", the Russian power engineering company is performing a full-scale upgrade of six power units of the plant.
The upgrade, with an increase in the total capacity of six power units of the plant from 1800 to 1950 MW, was organized in three stages.
The first stage was implemented in 2019, when power units Nos. 3 and 4 were put into operation, both equipped with equipment from Power Machines.
At the second stage, power units Nos. 5 and 6 were put into service. The scope of work completed by Power Machines includes a comprehensive upgrade of turbine, generator, boiler and auxiliary equipment, introduction of automatic process control systems, and reconstruction of the automatic control system, as well as a full range of construction, installation, commissioning and installation supervision works.
Produced by the Russian facilities of "Leningradsky Metallichesky Zavod", plant "Electrosila", TKZ "Krasny Kotelshchik", and the Kaluga Turbine Plant, the equipment has improved performance to meet reliability and safety requirements. The service life of the newly installed turbine assemblies is 40 years, while capacity of each power unit has been increased by 25 MW – to 325 MW.
Completion of the upgrade of the largest thermal power plant in Central Asia is scheduled for this year, after the end of the third stage, when power units Nos. 9 and 10 will be put into service.
Implementation of the project will reduce the shortage of electricity in the country, ensure sustainable operation of the energy system of Uzbekistan, and positively affect the economic performance of the region.
