  6. Why XML • The Danish Datahub have already implemented XML documents based on ebIX® and ENTSO-E standards • Nord Pool Spot will offer XML interface spring 2014 • No existing alternative to XML for ENTSO-E documents • Most other markets (Banks, Health care, Transport…) has migrated, or has started to migrate to XML • NBS requires changes to all systems and changing syntax seems like a small additional cost Conclusion: • XML is the best choice for NBS message syntax

  7. Means of communication

  8. NBS requirements for means of communication • Same standard for all Nordic countries • Encryption (parts of the market) • Typically for bids to the different markets • Compression (XML are large) • The new formats will be notably bigger • Must handle both: • many-to-many communication (FI, NO, SE) • one-to-many communication (DK, i.e. datahub)

  9. Possible protocols • SMTP • Used in Norway and Sweden today • FTP • Used in Finlandtoday • Web Services • Used in Denmark today • E.g. AS4 or ebMS 3.0 • Not seen as realistic without a central hub, hence not further elaborated • MADES • Astrong candidate for a common Nordic communication platform

  10. MADES (MArket Data Exchange Standard) • General communication standard • based on web-services • developed by ENTSO-E to facilitate reliable and secure exchange of documents • Supports • Encryption • compression • Authentication • non-repudiation • Published by IEC as Technical Specification (2013) • The ECP (ENTSO-E Communication Platform) is free for the industry

  11. MADES Network

  12. Status • NBS has not yet made a decision regarding means of communication • Comments from the industry are welcomed!

  13. Message Standard

  14. NBS message exchangesBusiness Requirement Documentation • NBS has asked the Nordic Ediel Group (NEG) to specify the message exchanges related to NBS. This includes a set of Business Requirement Specifications (BRS): • BRS for NBS, version 1r4 (between NBS and market actors) • BRS for NBS, TSO/NPS communication, version 1r2(between NBS and TSO/NPS) • Overview of information exchange • sequence diagrams • Harmonised roles used in Nordic settlement • role model and definitions of roles • Process areas • UseCases, activity diagrams and process descriptions • Data view • Class diagrams and attribute usage

  15. NBS message exchangesTechnical Documentation • NBS User Guide for XML documents • Detailed description of data elements, formats, codes…. • Example XML files • Aggregated_Data_per_MGA_for_Settlement_Responsible-E31-E44.xml • EAR-Example.xml • ESS-Schedule-Example.xml • ESS-Confirmation-Example.xml • Validated_Data_for_Settlement_for_Aggregator-E66-E44.xml • Aggregated_Data_per_Neighbouring_Grid_for_Settlement_Responsible-E31-E44.xml • Validated_Data_for_Settlement_for_Aggregator-MGA-E66-E44.xml • Common Nordic XML rules and recommendations • Acknowledgement process • Basic rules for dates, times and periods • …

  16. Settlement in the overall context

  17. Breakdown of the settlement phase

  18. NBS Scheduling PhaseExchange Load Profile Shares (before the delivery month) • Arrow 1 is not handled in the first version of NBS • Arrow 2 and 3 are published on web

  19. NBS Scheduling Phase Report tradefrom Elspotand Elbas (before operational hour) • Green arrows are document in NBS BRS for TSO/NPScommunication • Blue arrows are documentedin other BRSs from NEG

  20. NBS Scheduling Phase Report bilateral trade • Black arrows are documented in NBS BRS • Green arrows are document in NBS BRS for TSO/NPScommunication • Blue arrows are documentedin other BRSs from NEG

  21. NBS Scheduling Phase Plan production • Green arrows are document in NBS BRS for TSO/NPScommunication • Blue arrows are documentedin other BRSs from NEG

  22. NBS Scheduling Phase Report trade from Balance Regulation Market • Green arrows are document in NBS BRS for TSO/NPScommunication • Blue arrows are documentedin other BRSs from NEG

  23. NBS Metering and Settlement PhaseExchange Metered data for End Customer billing • Blue arrows are documentedin other BRSs from NEG

  24. NBS Metering and Settlement Phase Exchange metered datafor imbalance settlement (2 – 13 days after delivery day) • Black arrows are documented in NBS BRS • Red arrows are document in NBS BRS, but proposed removed form NBS BRSs (not part of NBS scope) • Arrow 10 will be published on web

  25. NBS Metering and Settlement Phase Settle imbalance • Aggregated consumption per MGA will be further split into: • Interruptible consumption • Pumped • etc. • Blue arrows will be published on web • Black arrows are documented in NBS BRS

  26. NBS Reconciliation Phase Reconcile (not part of the first phase of NBS) • Arrow 1 will be detailed by HNR • Arrow 2 is an internal dataflow within the DSO • Black arrows is not handled in the first version of NBS

  27. Acknowledgements • NBS will use the ENTSO-E acknowledgement process • NBS will acknowledge all documents received • NBS expect an acknowledgement in return for all documents sent • The ENTSO-E acknowledgement document is simplified in comparison to the documents used today (CONTRL/APERAK) • One structure • Less detailed codes

  28. The main processes and data exchanges have been specified, however some issues still remain • How to exchange master data (structure data), such as • MBA-MGA and MGA-MGA relations • Party information (IDs, responsibilities, roles, contacts …) • Address register • Test portal • Maintenance requests to ebIX® and ENTSO-E • Intermediate Nordic solutions will be used until/unless accepted by ebIX® and ENTSO-E • Specification of technical details • Identification schemes • Identification of Time Series • Rules for Direction, Delta value, signing convention

  29. Links to documentation • www.nbs.coop • BRS for NBS, between NBS and market actors • www.ediel.org, Nordic Balance Settlement (NBS) • BRS for NBS, including flows outside of NBS • BRS for NBS, TSO/NPS communication • NBS User Guide for XML documents • Example XML files • www.ediel.org, Nordic TSO XML Project • Common Nordic XML rules and recommendations
