Key findings
System flexibility needs in Europe are expected to double by 2030 and increase six‑fold by 2050 compared to early‑2020s levels. The main driver of this rapid increase in 2030 is the changing generation mix, especially the massive deployment of solar PV and its distinct daily production profile. In the longer term, towards 2040 and 2050, growing electricity demand is expected to become the dominant driver. Moreover, the increase in anticipated system flexibility needs might be amplified by the slow expansion of electricity grids. Even in a favourable scenario where transmission grids grow by roughly a third by the end of the current decade, redispatch costs are expected to rise from about 5 to 9 billion euros per year. Renewable generation curtailment is also expected to increase sharply, by 50 to 121 TWh in 2030, due to network bottlenecks.[5] These numbers highlight how grid development and flexibility provision are deeply interlinked
