Swiss energy giant's chief executive highlights urgent need for electricity agreement with EU to maintain grid stability and ensure security of supply.
"Without an electricity contract, Switzerland would no longer be able to import energy to the same extent as before in difficult situations."
"This is not primarily about large annual deliveries, but rather about so-called balancing energy, which must be imported or delivered within 30 seconds."
Switzerland is flirting with a precarious energy future, and the warning signs are flashing red. Alpiq CEO Antje Kanngiesser has issued a stark ultimatum: without a solidified electricity agreement with the European Union, the nation's security of supply hangs in the balance. In a candid interview with NZZ am Sonntag, Kanngiesser dismantled the notion that Switzerland can operate as an energy island in an increasingly interconnected continent.
The threat is not theoreticalâit is operational. Without a binding treaty, Switzerland risks being relegated to second-class status on the European grid, unable to import vital energy during critical shortages. While political debates drag on, the physical reality of the grid demands cooperation. Kanngiesserâs message is unequivocal: isolation is a luxury Switzerland cannot afford. As the country grapples with its future relationship with Brussels, the energy sector is making it clear that political stubbornness could lead to physical darkness.
The danger lies not in the annual bulk transfer of power, but in the razor-thin margins of "balancing energy." Kanngiesser highlighted a staggering technical reality: grid stability often hinges on electricity that must be imported or delivered within a mere 30 seconds. This is the heartbeat of the European power systemâa rapid-fire exchange that keeps lights on and factories running across the continent.
"This balancing takes place across the entire European electricity grid," Kanngiesser explained. If Switzerland is decoupled from these real-time mechanisms, the ability to stabilize the domestic grid during fluctuations plummets. We are talking about instantaneous shocks to the system that require immediate external support. Without the treaty, Switzerland loses its guaranteed access to this 30-second lifeline, leaving the grid vulnerable to cascading failures that domestic production alone cannot mitigate fast enough.
For those pinning their hopes solely on a nuclear renaissance, Kanngiesser offers a sobering reality check. The Alpiq chief emphasized that even existing nuclear infrastructure is not a silver bullet for independence. These plants require mandatory overhauls lasting four to six weeks, creating significant supply voids that must be filled by imports. Furthermore, the risk of unplanned outages means that "all technologies need a backup."
The timeline for new nuclear capacity is equally unforgiving. Kanngiesser warns that even if the political ban on new nuclear plants were lifted today, it would not solve Switzerlandâs energy crunch for the next 15 to 20 years. The country faces a critical gap of two decades where theoretical reactors provide zero actual voltage. Relying on a distant nuclear future while ignoring the immediate necessity of European integration is a strategic error that leaves the current grid exposed to inevitable downtime and maintenance cycles.
The path forward demands a pragmatic, two-pronged assault on energy insecurity. Kanngiesser is calling for an aggressive acceleration of existing domestic projects while simultaneously campaigning for the EU electricity agreement. It is not an "either/or" proposition; it is a desperate need for both. While the long-term operation of existing nuclear plants is being examined, the immediate priority must be the implementation of renewable expansion projects that are currently stuck in the pipeline.
Switzerland stands at a crossroads. The technology to generate power exists, but the infrastructure of cooperation is crumbling. By pressing ahead with domestic production and securing a seat at the European table, Switzerland can safeguard its economy. However, as the Alpiq CEO makes clear, time is a luxury the grid does not possess. The energy sector is ready to act, but it requires the political will to sign the treaty and pour concrete for new local projects immediately.
