TC 57 CIM user Group Meeting October 2010 San Francisco Cyril Effantin EDF R&D cyril.effantin@edf.fr TC 57 – WG16 Cim Market Extensions for EU CIM and ENTSO-E Market EDI harmonization For transmission market EDI leveraging a Common approach for derivating CIM into XML exchanged data EDF prototypes to support it.

3. TC 57 CIM user Group Meeting October 2010 San Francisco 3 Agenda  Introduction  Aims of the IEC ENTSO-E Market EDI standards harmonization  Methodological framework  Short methodology examples  EDF Prototypes to support the methodology  Conclusion

4. TC 57 CIM user Group Meeting October 2010 San Francisco 4  Markets integration across Europe requires market consistency & seamless communication at several levels:  Inter-Participants  Participants to Power Exchanges & TSOs  Inter-TSOs  Second European Electricity directive requiring open transmission capacity allocation which increases the need for aligning physical models with market signals  Auction office  Transparency in ATC allocations  Need for expanding interoperability between energy stakeholder IT applications (expanding standards down to data models) Initiative background – Strategic importance of standardization within Europe

5. TC 57 CIM user Group Meeting October 2010 San Francisco 5 ENTSO-E ( European Network of Transmission System Operators for Electricity http://www.entsoe.eu/ )http://www.entsoe.eu/  Harmonization Works started in 2005 within IEC-ETSO collaboration ( European Transmission System Operators )  from July 2009, ETSO is now fully merged into ENTSO-E ~ 500 million citizen served  650 GW Generation  230 000 km EHV-HV lines  1 500 000 km MV/LV lines Demand: 3 000 TWh/year Exchanges: 300 TWh/year Investments by 2030 for T&D: ~500G€ ENTSO-E: 42 TSOs from 34 countries

6. TC 57 CIM user Group Meeting October 2010 San Francisco 6 Separation of transmission networks from production and supply Yet stronger unbundling rules in 3 rd EU Directive Individual players' initiatives Push for investments in interconnections Capacity constraints in existing infrastructure Security of energy supply within each country Emergence of market coupling, e.g. trilateral and soon Central- Western Europe EEX- Powernext-Belpex Vertical disintegration Phase I Interconnection reinforcements Creation of power exchanges Integration of EU landscape EU grouped countries into 7 … + regional markets Extension of market coupling between countries European integration Phase II In parallel: growing importance of renewables Drive towards sustainable energy...... with increasingly volatile production profile Evolution towards pan- European backbone? Sustainability The TSOs’ need for stronger and faster evolution towards EU integration

7. TC 57 CIM user Group Meeting October 2010 San Francisco 7 Strategic targets  Market unbundling has distributed Business Processes across various Energy Stakeholders, typically :  Scheduling  Capacity allocation and nomination  Reserve management  Customer switching  Settlement Calculations…  This however requires coordination of standards across stakeholders  Standardisation is a key element for IT Total Cost of Ownership reduction through :  Harmonization of business processes  Improved component reusability  Market Interfaces  Reduced integration costs

8. TC 57 CIM user Group Meeting October 2010 San Francisco 8 Aims of IEC - ENTSO-E Market EDI standards harmonization  CIM Market Extension CME creation  Mainly north American vision of the market in 2003  Taking into account European market design : OTC Over the counter market not modelled  Harmonization benefits  Integrating the European market standard defined by ENTSO-E Market EDI works into IEC Harmonized European role model Enhance IEC standards with business processes Many business processes already modelled by ENTSO-E Extensive business exchanged messages Reuse of the ENTSO-E implementation guides Building of a working framework based on UN/Cefact specification  Hosting the European profile as IEC international standards  Taking advantage of the standardization community

14. TC 57 CIM user Group Meeting October 2010 San Francisco 14 Common Methodological framework based on UN/Cefact CCTS UN/Cefact (United Nations/Centre for Trade Facilitation and Electronic Business) CCTS (Core Component Technical Specification) CCTS Gives a working framework to enhance semantic, interoperability in electronic data exchanges In particular, it helps to link business processes data exchanges with a common global information model (such as the CIM model) ex: ENTSO-E Scheduling Process

15. TC 57 CIM user Group Meeting October 2010 San Francisco 15 Common methodological framework inspired from UN/Cefact CCTS (Core Component Technical Specification) standard DMS OMS Exchanged Data analysis 1 Message Conceptual Model or Message Assembly (Exchanged at app interfaces) 4 Business Process Study: Ex: outage Management Contextual Model or Business Information Entity ( Profiles ) 3 (Sub-Set, Constraints, restrictions) 5 Implementation Message Model ou Syntax Binding Technological derivation XSD, OWL,RDFS, SQL …etc XML Exchanged Data Validation Information Model or Core Components ( CIM ) 2 CIM extensions

TC 57 CIM user Group Meeting October 2010 San Francisco 35  Un/Cefact based methodology facilitated the CIM ENTSO-E Market EDI harmonization.  Having a whole information model giving the next step for future European work, EDI harmonization.  The methodological framework reduced the number of added new classes into the CIM to cover all ENTSO-e market exchanged messages through their business processes.  Supporting the methodology with prototypes gives a real proof of concept. Feedback on the common methodological approach
