High electricity demand due to hydrogen production for the seasonal storage of significant solar power generation
Photovoltaics as Main Source
By 2050, photovoltaics will generate 76 TWh of electricity in Switzerland, with 72 GW installed capacity
Expansion of Wind and Water
An additional 6 TWh from wind power and 1 TWh from hydropower will enhance energy security
Power-to-Gas for Winter Electricity
Excess solar power from summer will be stored as gas and used for electricity generation in winter
Electrification of Transport and Heating
Fossil fuels will be replaced by efficient electric solutions in transport and buildings

Challenges
Utilizing Photovoltaic Overcapacity
Up to 10 TWh of solar power might go unused or unexported due to limited storage capacity
Efficiency Losses in Power-to-Gas
The reconversion of gas from excess solar power causes significant energy losses
Wind Power Expansion for Winter Needs
Despite wind power expansion, meeting winter electricity demand remains a major challenge
Increased Electricity Demand for Electrification
Electrifying transport and heating significantly raises electricity demand, requiring efficient solutions
