Multiple Paths. Multiple Futures.

We’ve selected four key scenarios to help you get oriented. Each offers a different vision for Switzerland’s energy system, representing different approaches to energy policy, technology, and ambition.

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

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

Explore scenario

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

Explore scenario

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

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

Explore scenario

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

Explore scenario

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

Explore scenario

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

Explore scenario

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

Explore scenario

VSE "offensive-integrated" Moderate build-out of renewables, gas power plants replace nuclear for winter generation

Explore scenario

Scenarios from individuals

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

Explore scenario

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

Explore scenario

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

Explore scenario

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

Explore scenario

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