Our history Over 100 years of Axpo

Axpo and Switzerland have a long-standing success story. Axpo's roots go back to the beginnings of electrification in Switzerland over 100 years ago. Since then, the company has grown steadily and is now the largest power supplier in Switzerland.

The giant battery in the Alps

Pumped storage power plants work like large batteries that store electricity in the form of water. One of the largest of its kind began operations in the Glarus Alps in 2016: The Axpo Limmern pumped storage plant has an output of 1000 MW - together with the Linth-Limmern power plants, this results in a total output of over 1500 MW. In terms of output, this roughly corresponds to the Leibstadt nuclear power plant.

The largest alpine solar plant in Switzerland

Together with IWB, Axpo has realized the largest alpine solar system in Switzerland at 2,500 meters above sea level. The system has been fully operational since the end of August 2022. The pioneering AlpinSolar project produces 3.3 million kilowatt hours of electricity per year - half of it in winter. This means we use solar energy at any time of the year and despite the sea of ​​fog.
