Geesthacht

Geesthacht
Geesthacht pumped storage plant, near Hamburg, has been in operation since 1958.

The Elbe river serves as the plant's 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 turbines must work in pump mode for around nine hours. This pushes the water over an 80 metre height difference.
