The European Interconnected System: ENTSO-E Founded 19 December 2008 and fully operational since 1 July 2009 Represents 43 TSOs from 35 countries 525 million citizens served 828 GW generation 305,000

7 Principles of operation: Security of Supply: the (n-1) - Criterion "N-1" CRITERION: Customer Any probable single event leading to a loss of Power System elements (generating set, transmission line, transformer, etc.) should not endanger the security of interconnected operation: TSO 1 TSO 2 Loss of Consumption Interconnected System Stability Violation of limit values (Current, Voltage, Frequency Deviation) Cascade of Tripping DSO n-1 6

8 Principles of operation: Security of Supply : Congestion Management Temporarily Congestion Structural Congestion TSOs initiate measures for avoiding and relieve congestions For ensuring system stability For maintaining a viable energy market 7

9 Summary For a secure and reliable energy delivery TSOs provide*: Load Frequency Control and Power Balance N-1 Security at every time Congestion Management *among many other services 8

11 Nomination process: Internal Trade BG Trader A BG Trader B *BG = Balancing Group Trader A and Trader B must nominate Schedules to AMPRION 10

12 Nomination process: External Trade BG Trader A *BG = Balancing Group Trader A must have a BG in CA AMPRION and CA TNG 1:1 Nomination Trader A nominates Schedules to AMPRION and TNG. 11

18 Summary The current Challenges of Scheduling in Fast Intraday Markets : XBorder Trading actually requires high efforts in TSO-TSO coordination --> Matching. All areas in the synchronous zone must be balanced at every time (Σ of Import/ Export = 0) Synchronization challenges with frequent nominations Exponential growth of data to be exchanged and processed 17

19 Agenda The Responsibility of a Transmission System Operator (TSO) What actually does a TSO? Structure of the transmission system. Challenges of Scheduling in Fast Intraday Markets What are the challenges a TSO faces? New Concepts for Aligning the Balancing Act of System Security and Fast Intraday Markets RG CE Verification Platform XBID 18

20 New Concepts The OLD world of today Disadvantages Designed for Day Ahead Markets Explicit Allocations Complex Time Consuming Inherit Redundancy 19

21 New Concepts: XBorder Trading Path Model vs Virtual Scheduling Area 20

22 New Concepts Market Coupling with Implicit Capacity Allocation Market TSO SA = Scheduling Area (~Control Area) BG = Balance Group SMS = Scheduling Management System = Congested Border 21

Go-Live expected in 2018 SA = Scheduling Area (~Control

23 New Concepts Market Coupling with Implicit Capacity Allocation Measure: Simplifying the Scheduling Process Go-Live expected in 2018 SA = Scheduling Area (~Control Area) BG = Balance Group SMS = Scheduling Management System = Congested Border 22

24 New Concepts Market Coupling with XBID XBID means Cross-Border Intraday and is a joint initiative among 5 PXs and 14 TSOs. XBID aims for a coupled Intraday-Marktet over Europe. Main conceptual features 1) Shared Order Book (SOB), 2) Capacity Management Module (CMM), 3) Shipping Module (SM) 23

29 Conclusion How to align high Frequency Intraday XBorder Trading close to Delivery Time and ensuring Grid Security for 525 Mio EU Citizens? Security first: TSOs provide n-1 security, balancing mechanisms, and congestion management Simplifying the Scheduling Process for XBorder trading Coupling of single markets together with implicit capacity allocation e.g. XBID Development of fast and reliable IT Systems that support centralized approaches e.g. Verification Platform 28
