Purposes of ETSO

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.

TF EDI

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.

Collaboration with IEC TC 57

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

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

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.
