6. 29.4.2014 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. 29.4.2014 Means of communication

8. 29.4.2014 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. 29.4.2014 Possible protocols SMTP Used in Norway and Sweden today FTP Used in Finland today 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 A strong candidate for a common Nordic communication platform

10. 29.4.2014 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. 29.4.2014 MADES Network

12. 29.4.2014 Status NBS has not yet made a decision regarding means of communication Comments from the industry are welcomed!
