Axpo is wholly owned by the cantons of northeastern Switzerland. The cantons in their capacity as the owners of the power plants meet their responsibility to continue to provide a secure and inexpensive supply of electricity for industrial and commercial enterprises and private households.

At  Axpo Group, electricity products, transport grids, trading, sales and services are all grouped together under a joint holding company. Axpo Group comprises Axpo AG, Centralschweizerische Kraftwerke AG (CKW) and Elektrizitäts-Gesellschaft Laufenburg AG (EGL). The group operates a powerful CO₂-free fleet of hydropower, nuclear power and new energy plants. In producing, trading and selling its power, Axpo relies on old and new partners in Switzerland and in Europe. EGL has been a successful player on the European electricity markets for around 50 years. Axpo Informatik AG develops and sells commercial IT software and hardware for all Group companies and a few cantonal electricity utilities. The cornerstone of Axpo's sustainable success is its approximately 3,700 qualified and highly-motivated employees.

Axpo AG, CKW and EGL provide electricity directly to numerous output distributors in their own franchise areas. The cantonal electricity utilities of the cantons of Aargau, Zurich, Schaffhausen, Thurgau, St. Gallen and both cantons of  Appenzell buy electricity for local distribution from Axpo, which, in addition to their direct customers also supply power to more than 400 independent regional and communal output distributors (city and municipal utilities, cooperatives, pools). In Central Switzerland this is the remit of the CKW Group.
