Liptovská Mara pumped storage power plant is located by the second "peak-load" reservoir in the upper section of the Váh catchment area, which performs the same functions as the Orava reservoir. The plant has two classical sets featuring the Kaplan turbine and two pumping sets featuring a diagonal reversible turbine (Dériaz system). In addition to the utilisation of the Váh river natural flows, the HPP thus also makes use of the water pumped to the upper reservoir at the time of electricity surplus in the system to generate electricity.
