Welcome to the
Power Switcher

There are many views on the future of Swiss electricity generation. The Power Switcher shows you different scenarios. Explore for yourself in which scenarios supply security is achievable, how much renewables we’ll have, or what it will cost. Go explore!

Not the Power Switcher you expected?
We’ve launched a new Power Switcher Viewer Mode, but the Power Switcher Expert Mode is still available. Access it here.

The Swiss energy scenarios
Axpo Renewables A balanced build-out of renewables, focusing on solar and wind. Green gas as winter-backup

Legend

A projection of the energy mix, demand and production for the year 2050 for the given scenario.
HydroPVNuclearWindGasBiomassFossilGeothermal Other
D : Demand • P : Production • Δ : Production Surplus
Axpo Landscape Ambitious nuclear and rooftop solar expansion to avoid landscape-impacting wind and alpine solar units
