Grid Storages in Germany
Germany has 25 grid storages mapped on the OverWatts open energy atlas — the 7th-largest fleet of the 58 countries that hold any, and 3% of the world's mapped total. Of these, 20 operating and 3 under construction or proposed. The largest is Goldisthal hydroelectric plant (1.1 GW).
The largest owner-operators are Vattenfall AB (7), EnBW Energie Baden-Württemberg AG (EnBW) (6) and Energiedienst Holding AG (5) — Vattenfall AB alone is named on 28% of them. Half of Germany's grid storages in service predate 1967 (median commissioning year of the 20 with a known date) and the oldest still listed is Häusern hydroelectric plant, dating from 1932. 3 are in the pipeline, led by Riedl hydroelectric plant (300 MW), under construction. They account for 4% of every energy asset OverWatts maps in Germany.
