On September 4, 2017, hydroelectric unit bearing plant No. 1 was put into operation after refurbishment at the Volga HPP (a branch of RusHydro).
Under the hydroelectric unit refurbishment project, its hydro turbine, generator, field system, automation and balance of plant systems were replaced.
The new hydroelectric unit has improved performance characteristics that will allow increasing its capacity ultimately by 10.5 MW. The equipment revamping is being carried out in compliance with the RusHydro Comprehensive Modernization Program (CMP).
