A hydro plant with a capacity of 88.85 megawatts (MW) in the form of a reversible pumping station with three sets consisting of an alternator, a turbine and a pump. It can supply clean energy to more than 16,000 homes. It has two reservoirs to complete the pump-turbine circuit. The plant pumps water up to the upper reservoir when there is a surplus of energy, storing it to generate power when needed. This helps to achieve a higher integration of renewable energies into the system. A fall of almost 1,000 meters, the biggest in Europe when it was opened.
