8 Energy Transition: the flexibility challenge is real 50% generation capacity from variable RES by GW wind and PV to be connected by % Higher installed variable RES capacity compared to peak demand 14 Countries with wind and solar outputs likely higher than 80% 20% Reduction of dispatchable capacity margin over peak load 8

10 Interdependent measures to eliminate distortions Clean Energy Package: Where the European resource adequacy assessment identifies a resource adequacy concern Member States shall identify any regulatory distortions that caused or contributed to the emergence of the concern Strong Pan-European and technological interdependencies Need to coordinate and align activities Storage Energy Efficiency Generation Capacity Flexibility Interconnection Demand- Side Response 10

11 Spatial (Pearson s) correlations calculated from German onshore region 34_DE using the simulated wind generation data from the 2050 scenario Benefit from spatial aggregation Intuitively speaking, two countries do not face the most critical ramp at the exact same time due to: habitual differences between countries (e.g. different working time schedule, different mealtimes among countries, etc.) climatic conditions & spatial dependencies time zone differences Storage Energy Efficiency Generation Capacity Flexibility Interconnection Demand- Side Response 11

While in one country the residual load goes up, in another is possibly goes down and thus the region can be balanced via transmission of energy GW 5% +2.1 GW ES FR GB GW 53.9 GW 10 FR FR TR 21.4 GW 16.7 GW DE DE DE 0 DE+FR Aggregated PLEF Aggregated ENTSO-E Aggregated 12
