TF EDI
The Internal Electricity Market (IEM)
in the European Union
ETSO Members supply more than 490 million people with electric energy.
The consumption of electric energy amounts to about 3,200 TWh per year.
The length of EHV (400 and 220kV) lines is of more than 290 000 km.

Purposes of ETSO
TF EDI
 The study and development of common principles regarding the
harmonisation and establishment of rules in order to enhance
network operation and maintain transmission system security.
 To facilitate the Internal Electricity Market.
 The communication and co-operation with organizations and
institutions having similar objects.
 The investigation and solution of scientific and regulatory issues
of common interest to the TSO industry.

Synopsis
Created at the end of 1999 to provide technical solutions for
the Information Exchanges between the Internal Energy
Market participants.
 Immediate orientation towards the process analysis
and XML implementations
 Introduced a methodology based on UN/CEFACT
developments of the time.
 Introduced a market role model to provide a
harmonized
language
between
all
market
participants.
 First process introduced in 2002.

Work carried out by TF EDI
TF EDI
 Baseline development
 ETSO Modelling Methodology (based on UN/CEFACT)
 Electricity Market Harmonised Role Model
 Energy Identification Coding Scheme (EIC)
 Integrated in off the shelf software products available from
major energy sector software suppliers covering the principal
information interchange business requirements:




ETSO Scheduling System
ETSO Settlement Process
ETSO Capacity Allocation and Nomination
ETSO Reserve Resource Process
 Collaboration with UCTE (Union for the Co-ordination of
Transmission of Electricity):
 UCTE System Operator to System Operator Scheduling
 UCTE Metered Data Exchange on tie-lines

Collaboration with IEC TC 57
TF EDI
 IEC TC 57, WG 13 & WG 16 proposed a NWIP on « Deregulated
Energy Market Communications : CIM Market Extension
(CME) ».
 ETSO SC approved (28/04/2006) to work with IEC on the
following subject:
– The "Collection of domain models of energy markets (Use
Cases, UML plus text) covering the wholesale (energy,
ancillary services, etc.) and retail, based on a modelling
methodology including regional profiles of existing markets
reflecting different business rules together with design and
extension rules. This item leads to data requirements for
information exchange"

High level objectives
TF EDI
 Leverage the best of both ETSO and IEC worlds




TSO Business process expertise from ETSO
Object & application modelling methodology from IEC
Move toward UN/CEFACT methodology
Expand the CME model to other key Stakeholders
 Derive a first release of CIM Market Extension for Europe




Identify the Core components involved
Map the ETSO documents to CIM Model
Support ETSO naming schemes
Provide a first CME Europe Model
 Continue working on Market Extensions for US style markets
 Maintain these standards using the IEC methodology:
 Inclusion of yearly model updates and versions
 Opening of the object models to specific local market rules
 Independence of the model versus specific Information Technologies.

Conclusion
TF EDI
 ETSO benefited greatly from the introduction of a methodology
based on UN/CEFACT.
 ETSO and IEC TC57 have introduced the core component
philosophy with the additional requirement for identifying
Market Profiles prior to business implementation.
 Based on these, ETSO has created 4 key Electricity market
business processes that have been successfully implemented
by major software developers. These have become the
European Profile for information interchange.
 Along with the Harmonised role model, the business process
form a common and homogeneous language for use
throughout Europe.
