Power Plants in Switzerland

Switzerland has 55 power plants mapped on the OverWatts open energy atlas — the 55th-largest fleet of the 155 countries that hold any, and 0.2% of the world's mapped total. Of these, 49 operating and 3 under construction or proposed. Operating generation capacity totals 14.3 GW across 49 utility-scale plants of 100 MW and above. The largest is Leibstadt nuclear power plant (1.3 GW).

The largest owner-operators are Axpo Power AG (24), BKW Energie AG (22) and Industrielle Werke Basel (IWB) (22) — Axpo Power AG alone is named on 44% of them. Half of Switzerland's power plants in service predate 1962 (median commissioning year of the 49 with a known date), 4 came online in the past decade and the oldest still listed is Mittelbünden hydroelectric plant, dating from 1910. 3 are in the pipeline, led by Lago Bianco hydroelectric plant (1.0 GW), under construction. They account for 59% of every energy asset OverWatts maps in Switzerland.
