Hydropower expansion less than expected

A confidential federal report has revealed that Switzerland's planned hydropower expansion will deliver far less electricity than voters were promised

In June 2024, nearly 70% of Swiss voters approved the electricity law and its sixteen flagship hydro projects, seen as central to the energy transition.

An internal review commissioned by Energy Minister Albert Rösti now finds that more than a third of the dams cannot be built as planned, with power companies having overstated their potential.

To fill the gap, officials are weighing new dams in protected areas — including sites near the Aletsch glacier, a UNESCO World Heritage area — angering environmental groups.
