Modernization and Performance Upgrade

Rationale for the Construction Work

The Waldeck II pumped storage power station was commissioned in 1974. Two pumped storage sets-units 5 and 6-have provided reliable service since then, generating valuable peak-load electricity with an aggregate output of 440 megawatts (MW)

 

 

After more than 32 years of service, it was high time to overhaul the entire facility for technical reasons.
