JSC RusHydro has completed renovation of hydropower unit No. 6 at the Volga HPP. Renovation program included the replacement of the hydro turbine, generator, excitation system, hydroelectric unit management and automation system, as well as auxiliaries. The equipment has been renovated in line with RusHydro's Comprehensive Renovation Program (CRP).
The new turbine features an improved design and is highly environmentally friendly. The renovated impeller has 5 blades instead of the former 6 and is designed for higher water flow rate through the turbine. This will make it possible to increase the hydropower unit capacity in the future by 10.5 MW.
