A large-scale revamp work is being carried out at the Ust-Kamenogorsk hydro power plant in Khazakhstan, aimed at significantly increasing its annual production of electricity.

The modernization work is being performed on the main equipment and auxiliary systems of the facility, which is located on the Irtysh River near Ust-Kamenogorsk in East Kazakhstan Province of Kazakhstan, reports The Astana Times.

AES Ust-Kamenogorsk hydro power plant director Yulia Kurii was quoted as saying by The Astana Times: "In the period from 2015-2017, we plan to complete replacement of two old units to modern ones and thereby increase the power of each of them from 82 megawatts to 91 megawatts.

"As a result, the annual electricity output at a hydraulic unit will increase by 63 million kilowatts per hour."

Capable of generating approximately 90 billion KW/h of electricity, the Ust-Kamenogorsk hydro power plant is owned and operated by AES.

Station duty engineer Roman Nepmnyaschii said: "For example, at the moment, the first, second and fourth machine are in operation and the third is undergoing reconstruction. The current load on existing mechanisms is 220 megawatts, while the water flow is 660 cubic metres per second."
