OJSC “Power Machines” and OAO “TGK-1” entered into a contract for the all-round reconstruction of the cascade of Vuoksinskaya HPP

On May 10, 2007 Valery Rodin, General Director of OAO “TGK-1” and Boris Vainziher, General Director of OJSC “Power Machines” signed a contract for the all-round reconstruction of the cascade of Vuoksinskaya HPP. The contract price amounts to approximately 5.5 billion rubles.

Reconstruction of the cascade of Vuoksinskaya HPP is one of the priority projects of OAO “TGK-1” related to the technical modernization of power generating facilities in the north-western part of Russia, which forms part of the Investment Program for 2006 – 2015. The investment program of OAO “TGK-1” covers more than 30 projects in four subjects of the Russian Federation and is estimated in more than 130 billion rubles.

Under the terms of the contract OJSC “Power Machines” will perform reconstruction of four 24.2 MW hydraulic units of Lesogorskaya HPP – 10 and four 24.2 MW hydraulic units of Svetogorskaya HPP – 11.

The contractual obligations of Power Machines include design, manufacturing, testing and supply of equipment, performing of erection supervision as well as starting and adjustment works. Upon the completion of the proposed work the power capacity of each hydraulic unit of Lesogorskaya HPP and Svetogorskaya HPP will increase up to 32.6 MW and 32.0 MW, respectively. The aggregate maximum power capacity of the cascade after the reconstruction will increase by 64.8 MW and will be equal to 258.4 MW while the service life of the hydraulic units will be extended up to 25 – 30 years. Such successful results of the reconstruction will be achieved by using of the latest technologies in the turbine flow part design, increasing of the flow part capacity and efficiency. The reconstruction of all of the objects is expected to be finalized by 2012.

Further cooperation may include the projects of all-round reconstruction of hydraulic units of Volkhovskaya HPP – 6 and Nizhne-Svirskaya HPP.
