With the vote of May 21, the debate about new nuclear in Switzerland is closed for many years to come. Nevertheless, the ban on building new NPPs can be considered more of a “pro forma” law, because in any case, new nuclear plants were not planned in the near future mainly for economic reasons. Also, the Swiss utilities currently do not have the financial resources and the balance sheet to stem such a huge upfront investment. In order for new nuclear projects to make a comeback, the government energy policy would need to change with regards to nuclear power or carbon-free generation, similarly to the UK, before something can happen. This would have also been the case if the vote would have been “No” last Sunday. The big difference with the “Yes” is that we cannot even expect any discussion on the topic any time soon.
