URL More about Geesthacht Pumped Storage Power Station
Geesthacht Pumped-storage Power Plant was commissioned in 1958. The power plant is situated by the River Elbe and is the largest power plant of its kind in northern Germany. The upper water reservoir, located almost 93 metres above sea level, is 600 metres long, 500 metres wide and has a water capacity of approximately 3.6 million m3. The plant has three turbines with a capacity of 40 MW each, giving a total capacity of 120 MW. After full discharge, the water is pumped up through three parallel pipelines to the water reservoir. The procedure of pumping up water and refilling the reservoir takes nine hours. Since 2001, the work was reduced to ten percent of the possible operating time because the state government had introduced a removal fee for surface water. This levy was now reduced to a tenth of the original amount.
