1 Energy Structure NCs - Germany- (update 2016)

2 Basic facts Area: km² Population: (2015) 4 TSOs 883 DSOs (source: BNetzA) 45 Mio. consumers (source: BNetzA) Peak load: approx. 86 GW (source: German TSOs) Average interruption of electricity (2014): <12 min (unplanned interruption without exceptional contingencies (source: VDE)) 1

3 Germany in the European meshed grid Interconnectors to: Austria; Czech Republic; Denmark; France; Luxembourg; Poland; Switzerland; The Netherlands. Source :ENTSO-E 2

4 Grid facts and characteristics The electricity grid in Germany is sub-divided into transmission grids (maximum voltage) and distribution grids (high, medium and low voltage) Voltage Level Total length (approx.) Transmission Grid 380kV km TSO Transmission Grid 220 kv km TSO High Voltage 60 kv to 110 kv km DSO Medium Voltage 6 kv to 60 kv km DSO Low Voltage 230 V or 400 V km DSO Responsibility Source :BMWI 3

8 Cooperation of TSO and DSO: Cascade in Generation Dispatching of Renewables In case of (n-1)- security violations in the EHV-grid due to high dispersed generation TSO and DSO collaborate to lower the infeed of renewable generation in DSOs grid. TSO initiates and DSOs operate these measures according following cascade: Transmission grid TSO Distribution grid 1. Level DSO DSO Distribution grid 2. Level DSO DSO Distribution grid n. Level DSO DSO Source: BDEW Grid area Generation Load 7 Hallo 7

9 Responsibilities within the cascade TSO monitoring the overall system Responsibility for SoS* Operative contact to DSOs / generators on TSO-Level Requests support by the DSOs TSO Support of industrial customers to SoS through decreasing / increasing load End user can be disconnected DSO Cascade Consumers Monitoring own system Operative contact to generators on DSO-Level Support of TSO to operate the cascade *SoS = Security of Supply Generation facilities Support of TSO / DSO to SoS through decreasing / increasing the power of generation units 8

28 Price Coupling of Regions (PCR) in Europe WHAT is PCR? Price Coupling of Regions (PCR) is the initiative of seven European Power Exchanges to harmonise the European electricity markets HOW is this done? By developing a single price coupling algorithm to be used to calculate electricity prices across Europe Source: EpexSpot 27
