Characteristics of Geesthacht Pumped-storage Power Plant

With installed capacity of 120 megawatts (MW), it is the largest of its type in northern Germany. The Elbe river serves as its lower reservoir.

The upper reservoir holds around three million cubic metres of working water, enough for the turbines to run at full load for four and a half hours. To completely fill the upper reservoir, all three machine sets must work in pump mode for around nine hours. This pushes the water over an 80 metre height difference.
