Energy supply A new nuclear power plant in Switzerland would not be possible until 2050 at the earliest
A new nuclear power plant in Switzerland would not be connected to the grid until 2050 at the earliest if the ban on new construction were lifted. This is the conclusion reached by experts from the Swiss Academies of Arts and Sciences in a new report.

Without significant state support, such a new build is also unrealistic, the researchers write in the report published on Tuesday.
The advantages of nuclear power - low-CO2, weather-independent electricity - are offset by risks, political hurdles and billions in investment. The revenues, on the other hand, are unclear in a largely liberalized electricity market that will be dominated by renewable energies in the future, especially in summer.
According to the report, only large Generation III/III+ reactors are realistic with an investment decision by mid-2035. These reactor types are already being built worldwide and, according to the experts, are safer than existing power plants. Smaller reactors are being developed, but first have to prove themselves.
