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
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
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
MADES Network

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

NBS message exchanges
Business 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

Settlement in the overall context

Breakdown of the settlement phase
29.4.2014
NBS Scheduling Phase
Exchange 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
Report trade from Elspot and Elbas (before operational hour)
• • 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 Phase
Report 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 Scheduling Phase
Plan production
• • 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 Phase
Report trade from Balance Regulation Market
• • 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 Phase
Exchange 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 data for 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
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
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
Acknowledgements
29.4.2014
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
