Measured by capacity, it is the third largest pumped storage power plant in France.
Characteristics.
Revin Pumped Storage Power Plant was constructed as an underground power station: Four Francis turbines which are used for both generating and pumping with a capacity of 200 MW each are located in a 115 m long, 17 m wide and 16 m high cavern. Four transformers are installed on the surface to connect the generators (13 kV) to the electrical grid (400 kV).
There are three reservoirs which are connected to the Revin Pumped Storage Power Plant.
The upper and lower reservoirs are separated by a vertical distance of 250 m.
