Austria — Energy Infrastructure

OverWatts maps 139 energy assets in Austria across 11 layers — the 54th-largest mapped base of 157 countries. They include 66 power plants, 26 grid storages and 16 interconnectors. Operating generation capacity is 15.1 GW, led by hydro at 67%. Refining capacity is about 207 kb/d.

The companies named on the most assets are Verbund Hydro Power GmbH (32), Illwerke vkw (15) and Tiroler Wasserkraft AG (TIWAG) (9), counting both ownership and operatorship. Half of Austria's mapped assets in service predate 1979 (median commissioning year of the 89 with a known date), 7 came online in the past decade and the oldest still listed is Vils Cement Plant, dating from 1904. 25 projects are under construction or proposed, led by Austria – Germany interconnection (planned) (4.0 GW).
