Provision of Grid Services To stabilise the system frequency to 50 Hz after a sudden imbalance, the transmission system operator (TSO) can activate different control reserves / ancillary services. The different levels of control reserves work on different, but overlapping timeframes Time Source: ENTSO-E 5

Ultra-High Power Charging leads to increased Demand on the Electricity Grid Experience from 50 kw fast chargers show that load on the grids comes with very high peaks and no load between charging events. Based on grid access tariffs this also places a burden on fast charging business cases. kw Load on Fast Charger (50 kw) Two vehicles charging Peak 90-100 kw After Peak Shaving 7

New Role of Power Provider The Power Provider is the operator of the local stationary battery energy storage system (BESS), who provides the charge point operator (CPO) the needed energy and power for the location. TSO Aggregator The Power Provider manages and optimises energy and power provision for the location by establishing links to electricity suppliers and aggregators for the commercialisation of the BESS flexibility, while keeping the grid connection needs to the local DSO at a minimum level.

Roll-Out of HPC Infrastructure in Europe Outlook Various projects, programmes and initiatives facilitate the large-scale roll-out of HPC infrastructure across Europe: EUROP-E : 400 HPC stations in 18 countries ULTRA-E: 25 HPC stations in 4 countries MEGA-E: 322 HPC stations in 20 countries E-VIA FLEX-E: 14 HPC stations in 3 countries CEUC Central European Ultra Charging: 118 HPC => 1.000+ HPC chargers will become reality soon! 17
Power Roll-Out of HPC Infrastructure in Europe Power Demand Average HPC location with 4 dispensers each with max. 350 kw Peak-power demand of 4 x 350 kw = 1.400 kw for location As charging process of E-vehicles is dependent on the end-user, it cannot be forecasted / scheduled as other energy demands Today, charging stations therefore have a standard load profile of 0 1 => 100% of Energy Demand of a HPC is Balancing Energy! 0 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 Time 18
Frequency Containment Reserves (FCR) Contracted Reserves Currently, TSOs in Central Europe contract about 2 GW of capacity for Frequency Containment Reserves (Primary Control). 350 130 35 23 830 170 ENTSO-E Region Continental Europe: 3 GW Kavsakbendi 413 MW GDK 700 75 64 155 19
HPC Peak-Demand vs. FCR Possible demand fluctuation at all HPC stations in Europe: 1.000 HPC stations x 1.400 kw x 0,7 simultaneity factor ~ 1 GW or ½ of the FCR in Central Europe Conclusions: Power Demand of HPC Infrastructure might have a big Impact on Grid Balancing! Local Buffer Batteries help to mitigate large Fluctuations and to lower Peak-Demand at HPC Stations and additionally provide FCR to TSOs! 20
