Période 1970 - 2015

Unit No. 10 consists of a 200 MW vertical shaft pump-turbine installed in a vertical pit, next to the lower reservoir and 1 km from the original 9-unit underground powerhouse. It was designed as a reversible unit and consists of two parts, the hydraulic hydropower turbine and the motor-generator. The set operates as a turbine as well as a pump by revering the direction of rotation.

A upgrading study was carried out to investigate the installation of new pumps which shall replace the existing storage pumps while maintaining the existing speed of the unit sets, whereby the rated power shall be increased as far as possible in the range of 70 to 100 MW.

To meet the increasing demand for peak energy, the plant capacity was extended in 2015. A 11th unit with a capacity of 195 MW in turbine mode and 189 MW in pump mode was installed in a separate cavern close to the existing powerhouse. The storage capacity of each of the two (upper and lower) reservoirs was extended by 500.000 m³, which corresponded to an additional increase in capacity of 350 MW.
