Nuclear Power and the Future Swiss Energy System
Joint White Paper from ETH Zurich & PSI | June 2026
A new study by 19 energy experts from ETH Zurich and the Paul Scherrer Institute (PSI) is investigated under which conditions the construction of new nuclear power stations may make financial sense for Switzerland’s future energy system. The findings of the study are based on four different energy models. These models calculate which technologies Switzerland could use by 2050 to cover significantly higher electricity demand as cheaply possibly and in a carbon-neutral way.
