The exhibition is all about electricity and its impact on the region. The starting point and important thematic focus is the first large hydroelectric power station in Europe, built in Rheinfelden in the 19th century.
Starting from the Rheinfelden power station, the two Swiss engineers Agostino Nizzola (1869-1961) and Charles E.L. Brown (1863-1924) laid the foundation for a network of electricity supply that today spans the globe.
