Switzerland reconsiders nuclear power ban amid shifting energy priorities

Swiss Energy Minister Albert Rösti has stressed the ongoing importance of nuclear power for the country's energy security. Speaking at an international nuclear energy congress in Paris, he described it as a key pillar for economic stability and affordable electricity. His comments come as Switzerland debates whether to lift its ban on new nuclear reactors.

Rösti argued that nuclear energy should not be seen as a niche solution but as a strategic foundation. He pointed out that investment in renewables would continue regardless, as decisions are based on existing regulations. He also suggested a sliding market premium as a potential way to fund new nuclear plants in Switzerland.

The minister acknowledged that Switzerland is not currently facing an immediate energy crisis. Strong storage capacities and diversified supplies have helped maintain stability. However, he warned that a prolonged conflict in Iran could make it harder to fill gas storage by autumn. To prepare, he is working with energy companies, cantons, and cities through a crisis management structure. Rösti also addressed the political debate around the Blackout Initiative, saying it was unlikely the National Council would reject the Council of States' decision. His remarks reflect a broader shift in Europe's energy policy since Switzerland's 2017 decision to phase out nuclear power. The Ukraine war, climate targets, and concerns over Germany's 2023 nuclear exit have led to renewed openness toward nuclear energy. Switzerland itself is now reconsidering its reactor ban, with a vote in the Ständerat scheduled for March 2026.

Rösti's stance highlights a growing willingness to reassess nuclear power in light of changing global conditions. The debate in Switzerland will continue as the country weighs energy security against its long-term phase-out plans. A final decision on lifting the reactor ban is expected in 2026.
