Power Plants in Austria

Austria has 66 power plants mapped on the OverWatts open energy atlas — the 51st-largest fleet of the 155 countries that hold any, and 0.2% of the world's mapped total. Of these, 51 operating and 7 under construction or proposed. Operating generation capacity totals 15.1 GW across 51 utility-scale plants of 100 MW and above. The largest is Simmering power station (1.3 GW).

The largest owner-operators are Verbund Hydro Power GmbH (23), Illwerke vkw (8) and Tiroler Wasserkraft AG (TIWAG) (6) — Verbund Hydro Power GmbH alone is named on 35% of them. Half of Austria's power plants in service predate 1979 (median commissioning year of the 51 with a known date), 4 came online in the past decade and the oldest still listed is Vermunt hydroelectric plant, dating from 1930. 7 are in the pipeline, led by Lunersee II hydroelectric plant (1.0 GW), under construction. They account for 47% of every energy asset OverWatts maps in Austria.
