The project on modernization of the Varzob hydroelectric power plant-1 (HPP-1) will begin soon. According to the Barki Tochik National Energy Holding, the modernization will be carried out by Indian companies Bharat Heavy Electricals Limited (BHEL) and the National Power Corporation (NHPC). The Indian government has issued a grant worth US $17 million to implement the project. The Indian general contractors held a tender to select a contractor for construction works.

Hydro-mechanical works are carried out by the Indian companies,said a source in Barki Tochik.According to the source, during the first phase, the durability of the foundation of the HPPs building and supporting structures was tested, and the water-diverting structure was renovated. It is necessary to solve the issue of stopping the HPPs operation and drain the water intake. However, experts are looking for the ways to drain the water intake so that the water supply of Dushanbe is not stopped,said the source.He noted that all works at the Varzob HPP-1, including the construction work, should be completed by March 2011.After that, the Indian companies will begin engineering works,the representative of the Barki Tochik reported. Modernization will increase the plants capacity from 7.3 to 9.4 megawatts, and will extend the operability of the hydroelectric generating complex for another 50 years. The Varzob HPP-1 provides electricity and drinking water to the entire Varzob region and part of Dushanbe, said the source.The system of the Varzob HPPs consists of three power stations. The largest is the HPP-2, with the capacity of 14.76 megawatts. The capacity of the HPP-1 is 7.3 megawatts and of the HPP-3 -- 3.52 megawatts. The Varzob HPP-1 was the first hydroelectric power plant commissioned in Soviet Tajikistan in 1936.
