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

Means of communication
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)
29.4.2014
Possible protocols
SMTPUsed in Norway and Sweden today
FTP Used in Finland today
Web Services Used in Denmark todayE.g. AS4 or ebMS 3.0Not seen as realistic without a central hub, hence not further elaborated
MADESA strong candidate for a common Nordic communication platform
29.4.2014
MADES (MArket Data Exchange Standard)
General communication standardbased on web-servicesdeveloped by ENTSO-E to facilitate reliable and secure exchange of
documents
SupportsEncryptioncompressionAuthenticationnon-repudiation
Published by IEC as Technical Specification (2013) The ECP (ENTSO-E Communication Platform) is free for the
industry

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

Message Standard
29.4.2014
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

Breakdown of the settlement phase

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
29.4.2014
NBS Scheduling Phase

• Green arrows are document in NBS BRS for TSO/NPS communication• Blue arrows are documented in other BRSs from NEG
29.4.2014
NBS Scheduling PhaseReport bilateral trade
• Black arrows are documented in NBS BRS • Green arrows are document in NBS BRS for TSO/NPS communication• Blue arrows are documented in other BRSs from NEG

29.4.2014
NBS Metering and Settlement PhaseExchange Metered data for End Customer billing
• Blue arrows are documented in other BRSs from NEG
29.4.2014
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
29.4.2014
NBS Metering and Settlement Phase
Aggregated consumption per MGA will be further split into:
• Interruptible consumption
• Pumped• etc.
Settle imbalance
• Blue arrows will be published on web• Black arrows are documented in NBS BRS
29.4.2014
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
29.4.2014
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
29.4.2014
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
