The new turbine boasts an improved design and high environmental safety. The replacement will increase the hydropower unit capacity from 115 MW to 125.5 MW. Works were performed in accordance with the Comprehensive Renovation Program (CRP) of RusHydro, the only and unique production power asset upgrading program by its scope.
The runner of the new five-bladed turbine is designed for higher water flow rate, which makes it possible to increase the capacity, as well as to minimize idle discharge through a spillway dam (extra electricity generation). Main hydrogenerator components have also been replaced, and advanced control, vibration monitoring and diagnostics systems have been installed on the unit.
