Electricity consumption is rising substantially, winter supply relies on gas power plants, imports and moderate expansion of renewables
Electrification challenge
Electrification places ever-growing demands on the power system
Not winter supply without imports
A certain dependency from neighbor countries is sensible for full winter supply
Peak-shaving for PV surpluses
In addition to storage, peak shaving may be necessary in summer with PV surpluses
Gas power plants against winter gap
Climate-neutral generation from gas requires certificates, carbon-capture-and-storage or renewables gases

Challenges
Substantial increase in demand
Total energy consumption is decreasing thanks to electrification and increased efficiency, but this leads to a substantially higher electricity demand
Agreement with EU
Electricity trade with neighboring countries thanks to an electricity agreements with EU makes the system more resilient and secure
Surpluses in summer
More flexibility such as storage in the system is needed to make sensible use of summer surpluses
Gas power plants against winter gap
Gas power plants must be used as a supplement in winter, with a preference for climate-neutral operation

Levelized cost
We use Levelized costs of electricity (LCOE). Future costs may rise as cheaper plants are replaced. High demand and costly technologies like rooftop PV can further increase costs. See Expert Mode for details on technology costs.
