Grid Storages in Austria
Austria has 26 grid storages mapped on the OverWatts open energy atlas — the 6th-largest fleet of the 58 countries that hold any, and 3% of the world's mapped total. Of these, 21 operating and 5 under construction or proposed. The largest is Lunersee II hydroelectric plant (1.0 GW).
The largest owner-operators are Verbund Hydro Power GmbH (9), Illwerke vkw (7) and KELAG (3) — Verbund Hydro Power GmbH alone is named on 35% of them. Half of Austria's grid storages in service predate 1981 (median commissioning year of the 21 with a known date), 3 came online in the past decade and the oldest still listed is Rodund I hydroelectric plant, dating from 1943. 5 are in the pipeline, led by Lunersee II hydroelectric plant (1.0 GW), under construction. They account for 19% of every energy asset OverWatts maps in Austria.
