In future, renewable energies should assume a more prominent role in the area of Swiss electricity supply. At present, nuclear power plants and fossil energies provide relatively continuous streams of electricity. In contrast, wind and solar electricity are dependent on external conditions – leading to the volatile feed-in of this power. This will have an impact on imports, exports and electricity prices.
This raises the following questions: can the Swiss electricity market handle these challenges on its own and achieve the objectives stated under Energy Strategy 2050 without further legislative support? And: will the higher share of renewable energies put the reliability of the Swiss electricity grid at risk?
Researchers from the University of Basel and ETH Zurich investigated these questions as part of a joint project. In doing so, they based their work on both technical and economic models for the Swiss and European market. In the sub-project presented here, these models are combined to create a meaningful framework.
With this linked model structure, the impact of various future scenarios can be simulated. It also provides hourly market data which allows for it to be examined how the renewable energies affect electricity imports and exports under different market conditions. This also allows for the identification of seasonal or day-dependent patterns.
