Vattenfall Europe Generation AG subjected the pumped storage power plant (originally commissioned in 1958/59) to reconditioning. The 2 pumped storage units, each with a capacity of 40 MW in turbine operation and 36 MW in pumping operation, were subjected to a comprehensive overhaul from 2012 to 2014. In addition to the main mechanical components (such as pipework, hydraulic equipment units and generators), the complete electrical and I&C equipment was upgraded to meet the state of the art.
