Agenda

• Introduction
• Aims of the IEC-ETSO standards convergence
• Methodological framework
• Short methodology examples
• Progress status
• Next steps

3
Initiative background Strategic importance of
standardization within Europe

• Markets integration across Europe requires market
  consistency seamless communication at several
  levels
• Inter-Participants
• Participants to Power Exchanges TSOs
• Inter-TSOs
• Need for expanding interoperability between
  energy stakeholder IT applications (expanding
  standards down to data models)
• 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

4
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

5
Aims of IEC European Standardization

• 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
• IEC European Market Model benefits
• Integrating the European market standard defined
  by ETSO works into IEC
• Harmonized European role model
• Enhance IEC standards with business processes
• Many business processes already modelled by ETSO
• Extensive business exchanged messages
• Reuse of the ETSO 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

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)

Proposed CIM Extensions

• With Scheduling and Capacity Allocation processes
  studies we have the following new CIM classes
• MarketRole
• Process
• TimeSeries
• BidTimeSeries
• Auction
• Price

24
Progress Status

• European Market Profile Candidate release
• CIM /UNCefact derived Core Components
• CIM Information Model Extensions
• European message models for all business
  processes
• Message assembly and syntactic models for all
  documents
• Methodology Rules transmitted for review ?
  Technical Specification and later part of the
  WG16 standard
• ESS (Scheduling) Documents finalized ? Approval
  on the 13th November 2007
• ECAN (Capacity Allocation) Documents drafted
• ? Official ETSO Confirmation in April 2008
• The ETSO TF EDI agreed that the methodology
  outlined in cooperation with IEC should be
  promoted.

Feedback

• Un/Cefact based methodology facilitated the
  CIM-ETSO harmonization.
• Having a whole information model giving the next
  step for future European work, EDI harmonization.
• Growing interests and involvement of both ETSO
  and European IEC TC57 members.
• European Task force methodological framework is
  relevant for future profiles development.

27
Next Steps

• Standard publication
• European Profile Model finalization In progress
• Model documentation In progress
• Methodology Rules finalization In progress
• European Market Profile Release and Publication
• CIM Model harmonization
• New Information classes and associations
  Harmonization with North American Market Profile
• UN/CEFACT data types
• Modelling supporting Tool
• Support for modelling requirements
• Automate syntactic message Generation schemas and
  validation
