Power Machines OJSC has manufactured an impeller and guide vanes to upgrade hydropower unit No.2 of Rybinskaya HPP.

The scope of Power Machines contract obligations includes design and manufacture of a 70 MW hydropower unit with its auxiliary equipment and automated control system and their delivery to the plant, as well as dismantling of the old equipment and installation of the new one, services on installation supervision, commissioning and putting into operation of the new equipment. 

Developments made by Power Machines specialists and successfully proved while fulfilling orders for Volzhskaya, Zhigulevskaya and Cheboksarskaya HPPs have been applied in the design of the guide vanes and impeller for Rybinskaya HPP. The implemented solutions allow to ensure high reliability of mechanisms, as well as to achieve fundamentally new parameters of environmental performance. The shipping of the hydropower equipment will be completed by the end of June.

Earlier Power Machines took part in the reconstruction of Rybinskaya HPP for which the company manufactured and supplied two 63.2 MW hydropower units within the period from 1998 to 2002. As the result of that upgrade the capacity of each hydropower unit increased by 8.2 MW.
