Coo-Trois-Ponts is the largest Belgian pumped storage power plant . It is located in the Ardennes and has a turbine output of 1,164 megawatts that can be delivered over a period of five hours. It is the ninth most powerful pumped storage plant in Europe.

technology

The power plant consists of two phases, each with three Francis - pump turbines of Voith . Coo I was put into operation in 1969 and Coo II in 1978. The units 1 to 3 of Coo I each have an output of 158 megawatts in turbine mode and 157 megawatts in pump mode. The units 4 to 6 of Coo II each have an output of 230 megawatts in turbine mode and 210 megawatts in pump mode. In total, Coo I has 474 megawatts or 471 megawatts and Coo II has 690 megawatts or 630 megawatts, the total power plant has 1,164 megawatts or 1,101 megawatts (turbine output and pump output respectively).

Scheme of the pumped storage power plant

The power plant has two upper basins that are not hydraulically connected to each other. Both pools together have a volume of 8.5 million cubic meters, cover an area of ​​around 60 hectares and are deeper than 25 meters. The common lower basin is formed by two dams and takes up an area of ​​72 hectares when full. There is a height difference of 275 meters between the upper and lower basins. The turbines are located in a 128-meter-long, 22-meter-wide and 40-meter-high cavern inside the mountain. Two pressure pipes with a length of 995 meters and 1055 meters and diameters of 6.5 meters to 8 meters lead from the upper basin to the turbines . A 210 meter long access tunnel leads to the cavern. The electrical energy is discharged from the cavern via two cable tunnels at the 20 kilovolt level. Outside the cavern, the transformation to 400 kilovolts and the connection to the transmission network takes place via a switchgear .
