Uzbekenergo State Joint-Stock Company plans to announce tenders to modernize five hydropower plants (HPP) in two regions of Uzbekistan in late November - early December, an Uzbekenergo representative told Trend Oct. 21.

Uzbekenergo announced a prequalification tender for participants to modernize the cascades of three HPPs - two in the Tashkent region and one in the Fergana region in early October.

The pre-qualification tender has completed so far for the participants of the modernization of two HPPs in the Tashkent Region - Farhad HPP and Lower Bozsu cascade (HPP-14) with a total cost of $165.7 million, announced in April 2014. A tender is planned to be announced in December to choose general contractors.

The projects with a total cost of $ 335 million envisage the replacement of generators and turbines, as well as electrical equipment, protection relay and communication system. The project implementation will extend the operation of stations and increase hydropower generating capacity up to 50 MW.

The projects will be financed through the Islamic Development Bank in the amount of $ 200 million and assets of the Uzbek side.

It was previously reported that the Russian Silmash company completed the modernization of the first unit by replacing an impeller at the Charvak hydropower plant, a head hydropower plant as a part of the Chirchik- Bozsu cascade of the hydropower plants in August 2014.

Earlier, it was reported that Uzbekenergo concluded a contract for the modernization of the four hydraulic units of the Charvak hydropower plant in 2012.

Under the contract, Russian company will modernize another three hydro generators with capacity of 155 megawatt each. Following this, the capacity of each unit will increase to 175 megawatt, which will allow to generate additional 120 million kilowatt hours per year.

The project with the total cost of $53.79 million is financed with the equity of Uzbekenergo and loans from Uzbekistan's Reconstruction and Development Fund in the amount of $35 million.

Chirchik-Bozsu cascade of hydropower plants is divided into five cascades, namely, Orta Chirchik hydro power plant (885 megawatt), Chirchik hydro power plant (190.7 megawatt), Kadyrin hydro power plant (44.6 megawatt), Tashkent hydro power plant (29 megawatt) and Lower Bozsu hydro power plant (50.9 megawatt).

The total installed capacity of all the hydro power plants is equal to 1,200 megawatt, while the average annual generation is 4.67 billion kilowatt hours.

Currently, 45 power plants with the total capacity of nearly 12,800 megawatt operate in Uzbekistan's power supply system. The major part of the electricity - up to 90 percent - is produced by 10 thermal power plants of Uzbekenergo with the total installed capacity of 10.6 million kilowatt.

The company's 29 hydro power plants, with the installed capacity of 1.4 million kilowatt, are united in the cascades of hydro power plants and operate with running water.

The remaining part of the electricity is generated by stand alone thermal power plants of industrial enterprises and small hydro power plants of the Ministry of Agriculture and Water Industry.
