Landscape

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, 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

Axpo Landscape Ambitious nuclear and rooftop solar expansion to avoid landscape-impacting wind and alpine solar units

Energy Law ("Mantelerlass") Targets of 35 TWh of renewable energy by 2035 and 45 TWh by 2050, plus 6 TWh of renewable winter electricity, of which 2 TWh hydropower

Business as usual Without increased investments, winter import dependency will rise strongly, making blackouts likely after the nuclear shutdown

Scenarios from Industry & Institutions

BFE Energy Perspectives 2050+ The Ministry of Energy envisions an ambitious solar expansion, winter imports, and a few other renewable sources

Economiesuisse Longer nuclear lifetime and solar expansion, along with moderate demand growth, result in moderate imports and a high summer surplus

ETH Energy Science Center Strong imports and a summer surplus, coupled with an ambitious build-out of solar and hydro

Helion A solar-focused build-out and moderate growth in other renewables lead to winter imports and a high summer surplus

Swissolar Solar expansion, moderate growth in other renewables, and hydrogen to absorb a larger share of the summer surplus

VSE 2025 Electricity consumption is rising substantially, winter supply relies on gas power plants, imports and moderate expansion of renewables

Scenarios from individuals

Grossen (GLP) Robust solar build-out and moderate development of other renewables. Green gas as winter-backup

Rechsteiner (SP) A renewable and exchange-based scenario, with solar and hydro build-out leading to winter imports and significant summer exports to neighboring countries

Nordmann (SP) High electricity demand due to hydrogen production for the seasonal storage of significant solar power generation

Schwarz (ENSI) Maximum additions of wind and alpine PV as well as more hydro power balance strongly increasing demand. Few imports needed.

Wasserfallen (FDP) New nuclear and gas plants aim to keep the current import-export balance
