The success story of Energy Zürich began in 2003, following the involvement of the Parisian NRJ Group and the renaming of Radio Z to Energy Zürich. Meanwhile, Energy Zürich is not only the most listened-to private radio station for 15- to 49-year-olds, but also the number 1 across all target groups since the second half of 2015. Energy Zürich is part of the Energy Group, alongside its sister stations Energy Bern and Energy Basel. With its shows Energy Mein Morgen, Energy Midday, and Energy Downtown, Energy Zürich guides listeners through the week, and with Energy Weekend, through the weekend.
