The fundamental and yet not satisfactorily answered question is: How to adapt the European power system for integrating a high share of intermittent renewable electricity? In the framework of the project technically and economically feasible ways to achieve a 100% renewable power supply in Austria, and a high share in Europe, are investigated.

The project AutRES100 addresses this question and the following aspects:
• How to guarantee operationally and economically the system reliability and supply security?
• What are the technically and economically feasible ways for balancing power provision?
• Which adjustments are needed for the historically grown power plant portfolios?
• What is the future role of pumped hydro storage and other advanced electricity storage concepts?
• What is the importance of future electricity grid extensions?
• What is the possible role of flexible and intelligent demand side options (e-mobility, heating, cooling, smart grid)?
• Which options are provided by the interconnected European transmission grid?

For answering all these interrelated questions the highly resolved european power system investment planning and supply security simulation and optimization model HiREPS is utilized. The model is designed with hourly resolution and includes a detailed modeling of the variable renewables (hydro, wind and solar), of the pumped hydro and other storage options, of the conventional power plants, of the transmission grid and of possible future intelligent load response options (e-mobility, heating, cooling, smart grid). Investments and supply security are endogenously optimized within the model. In order to test the design of the future power system for a high share of intermittent renewables, high resolution weather data (e.g. solar irradiance, wind speed) is employed. Optimal transition pathways to a power system with a high share of renewables in all Europe are developed.

In the figure below the HiREPS simulation of the spot market prices and the corresponding residual load are illustrated on the example of the EEX market area for July 2030. The scenario assumes 14% wind and 9% solar power as share of annual demand. For this simulation the curtailment of the RES-E was allowed for avoiding negative prices.
