Switzerland reconsiders nuclear power as EU backs energy security shift

Swiss Energy Minister Albert Rösti has signalled a shift in Switzerland's approach to nuclear power. Speaking after an international nuclear energy congress in Paris, he argued that recent global events have reshaped the debate. His comments come as the EU increasingly backs nuclear energy for security and sustainability.

Rösti also addressed Switzerland's energy preparedness, including crisis measures introduced after the 2022/23 winter. He remains cautious about external conflicts but stresses the need to keep nuclear as part of the country's energy strategy.

The EU's position on nuclear power has changed dramatically since Russia's invasion of Ukraine in February 2022. In March that year, the European Commission classified nuclear as a sustainable energy source under its 'Taxonomy' rules. Two months later, the REPowerEU plan prioritised nuclear to reduce dependence on Russian gas. The 2024 extension of the EURATOM treaty to 2027 further cemented this shift.

France, under President Emmanuel Macron, and Finland led the push within the EU, with strong backing from the European Commission and Parliament. Even Commission President Ursula von der Leyen admitted that Europe's earlier move away from nuclear had been a mistake.

At the Paris congress, Rösti highlighted nuclear power's strategic role in today's energy landscape. He argued that Switzerland's 2017 decision to phase out nuclear no longer fits the current reality. Instead, he proposed keeping nuclear alongside renewables to strengthen Switzerland's position in the European energy market.

To fund new Swiss nuclear plants, Rösti suggested a sliding market premium model. However, he ruled out investing in French nuclear projects for now, insisting Swiss infrastructure must come first. He also dismissed concerns that supporting nuclear would undermine renewables, stating that both could coexist securely.

On broader energy risks, Rösti downplayed the direct impact of the Iran conflict on Switzerland but confirmed close monitoring. He remains focused on domestic preparedness, pointing to the crisis management framework established after the 2022/23 energy shortages.

Back in Switzerland, Rösti expressed doubt that the National Council would reject the Council of States' recent decision on the Blackout Initiative. The proposal aims to prevent power shortages by maintaining energy reserves, including nuclear as a backup option.

Rösti's stance reflects a broader European trend: nuclear power is regaining acceptance as a tool for energy security. Switzerland's potential policy shift would align with the EU's recent backing of the technology. The minister's proposals now face political debate, with the Blackout Initiative's fate hanging in the balance.
