Document exchange between Market Participants. The ETSO Solution for the Internal Electricity Market in Europe. ETSO Task Force 14, “Electronic Data Interchange with Market Participants”.

By Mr. Maurizio MONTI – RTE (France) Keywords: ETSO, Electronic data interchange, role model, Internal European electricity Market, ETSO Identification Code (EIC), XML.

Summary: ETSO, European Transmission System Operators, was founded in 2001 and is composed of European TSOs also Members from UCTE (Union pour la Coordination du Transport de l’Electricité), Nordel (Nordic Countries Association), UKTSOA (UK) and ATSOI (Ireland). The opening of the European Electricity Market requires a considerable amount of Electronic Data Interchanges (EDI) between all Market Participants. Consequently ETSO Task Force 14 was set up in order to harmonise EDI and especially the documents to be exchanged. Since its creation, ETSO TF 14 has developed the following industrial standards in compliance with UN/CEFACT recommendations: EMM: ETSO Modelling Methodology. ERM: ETSO Role Model of the Electricity Market. EIC: ETSO Identification Coding Scheme to identify parties and domains in the IEM. ESS: ETSO Scheduling System for scheduling exchanges. ESP: ETSO Settlement Process for settlement information exchanges between parties.

ETSO standards are published as Implementation Guides to enable IT vendors to develop off the shelf software solutions. Implementation of the ETSO standards is underway particularly in the wholesale markets of Austria, Germany, France, Hungary, Poland, Switzerland and Spain. These countries have started moving in a direction enabling European traders to have a common process to deliver their schedules. This paper has the following objectives: To provide an overview of the ETSO standards, To provide a situation report on the actual European Implementation of the ETSO

standards, To present the ongoing activities of ETSO TF 14.

1 ETSO Organisation 1.1 ETSO (European Transmission System Operators) European Electricity utilities have been cooperating for decades, mainly in order to maximise the system's reliability and quality of supply, while optimising the use of primary energy and capacity resources. Four regional organisations have emerged from this cooperation: ATSOI, the association of TSOs in Ireland; UKTSOA, the United Kingdom TSOs association; NORDEL, the Nordic TSOs, and UCTE, the Union for the Coordination of Transmission of Electricity, the association of

CENTREL and the TSOs of the Continental countries of Western and Central Europe.

In 1999, ETSO was created as an association with ATSOI, UKTSOA, NORDEL and UCTE as founding association members. However, on 2001 June 29, ETSO became an International Association with direct membership of 32 independent TSOs from the 15 countries of the European Union plus Norway and Switzerland. Since then, other TSOs have joined ETSO either as full members or associated members. The networks represented by ETSO supply more than 400 million people with electric energy. The consumption of electric energy amounts roughly to 3,000TWh per year.

1.2 Description of the ETSO Organisation ETSO is governed by an Assembly representing both associated and member companies, and by a Steering Committee, in which each of the member countries is represented.Various Task Forces (TF) are in charge of specific issues limited in scope: TF Cross-Border Trade. TF Network Access and Congestion Management. TF Electronic Data Interchange. TF Tariffs. TF Balance Management. TF Renewable Energy Sources (RES). TF South-East Countries TSOs. TF Security of Supply and Adequacy of Power Systems.

1.3 Tasks of ETSO ETSO pursues scientific aims on a non-profit basis and has the following objectives: To study and to develop common principles regarding the harmonisation and

establishment of rules in order to enhance network operation and maintain transmission system security;

To facilitate the internal European Market for electricity; To communicate and to cooperate with organizations and institutions having similar

objectives; To investigate and to resolve scientific and regulatory issues of common interest to the

TSO industry. Two basic rules of functioning have been adopted by ETSO: Tacking coordinated actions by a permanent exchange of information and a strict respect

of mutual engagements. Taking action only when the objectives of the proposed action cannot be sufficiently

achieved by its members acting independently of ETSO, without impeding the realisation of the internal European market for electricity.

2 ETSO TF 14 2.1 Objectives The objectives of the ETSO TF 14 are to: Develop data interchange standards required to ensure the operational efficiency of the

business processes within the scope of ETSO. Assist TSOs implementing the standards. Model data interchange for the business process defined by other ETSO task forces. Provide EDI technical support to other TSO organisations to promote the use of ETSO

EDI standards for their internal data interchange. Provide guidelines for data interchange security between TSOs and between TSOs and

market participants.

2.2 Working method The methodology adopted by ETSO TF 14 includes a project management scheme ensuring that the ETSO Steering Committee approves the initialisation of work on a new standard and upon completion of work approves the finalised output before publication. ETSO specifications shall be implementable standards in order to enable IT-vendors to develop off the shelf software solutions that can support the ETSO specifications in all countries where it is used. ETSO TF 14 strives to achieve the proof of concept of all new standards through pilot implementations.

2.3 List of documents issued. All ETSO TF 14 documents are available on the ETSO TF 14 Web site, www.edi.etso-net.org. The main documents are: EMM: ETSO Modelling Methodology. ERM: ETSO Role Model of the Electricity Market. EIC: ETSO Identification Coding Scheme to identify parties and domains in the IEM. ESS: ETSO Scheduling System for scheduling exchanges. ESP: ETSO Settlement Process for settlement information exchanges between parties.

2.3.1 ETSO Modeling Methodology (EMM) The ETSO Modeling Methodology (EMM) for the automation of data interchange for business processes uses a project document to get approval from all TSOs during a Steering Committee Meeting on the requirements for a given business process. On approval of the project, the methodology follows a four stage milestone approach that ends up with an implementation guide for the process in question that includes the workflow and the automated documents and the corresponding rules required to support the workflow.

The ETSO methodology starts with a use case, then follows the Rational Unified Process (RUP) using UML activity and sequence diagrams to derive the information exchange requirements. UML class diagrams are then created to define the information model for the contents for each document needed to support the information exchange. The UML models in question are based on the UN/CEFACT Core Components philosophy for supporting information concepts. Then XML schemas are automatically generated from the UML class diagrams. ETSO has created 10 rules for converting from UML to XML. They will soon use the UN/CEFACT rule for automatic XML schema generation from an XMI document. It includes corresponding UML and XMI profiles from UN/CEFACT. 2.3.2 ETSO Role Model (ERM) An essential ingredient to the standardisation effort is the formalisation of the Role Model. It defines the roles and objects used in data interchange. Data interchange standards have to use the definitions from the Role Model whenever compatibility is required. Consequently, it is therefore also the platform for discussions between TF 14 and other ETSO task forces requiring data interchange and external groups defining data interchange. The ERM provides a model identifying all the roles that can be played for given domains within the electricity market. The roles are of a logical nature (such as a trade responsible party) acting within a given domain (such as a balance area). A role represents the external intended behaviour of a party. Businesses carry out their activities by performing roles, e.g. system operator, trader, etc. Roles describe external business interactions with other parties in relation to the goal of a given business transaction. The objective therefore of decomposing the electricity industry into a set of autonomous roles is to enable the construction of business processes where the relevant role participates to satisfy a specific business transaction. A business process may be defined as a formal specification of a set of business transactions having the same business goal. For example, the day ahead schedule business process. A business transaction may be defined as a predefined set of activities that is initiated by a role to accomplish an explicitly shared business goal and terminated upon recognition of one of the agreed conclusions by all the involved roles. The ERM is updated accordingly with the evolutions of the IEM. The following table provides a short list of some roles definitions:

Role Description Balance responsible party A party that has a contract providing financial security and identifying balance

responsibility with the Imbalance settlement responsible of the market balance area entitling the party to operate in the market. This is the only role allowing a party to buy or sell energy on a wholesale level. The meaning of the word "balance" in this context signifies that that the quantity contracted to provide or to consume must be equal to the quantity really provided or consumed. Such a party is often owned by a number of market players. Equivalent to "Program responsible party" in the Netherlands. Equivalent to "Balance group responsible " in Germany. Equivalent to "market agent" in Spain.

Balance supplier A party that markets the difference between actual metered energy consumption and the energy bought with firm energy contracts by the party connected to the grid. In addition the balance supplier markets any difference with the firm energy commitment [of the party connected to the grid] and the metered production. There is only one balance supplier for each metering point.

Role Description Billing agent The party responsible for invoicing a concerned party.

Note: This role has been introduced into the role model in order to underline the fact that the Imbalance settlement responsible has not the responsibility to invoice. However this role is not specific to the settlement process and may be used in other processes as required.

Consumer A party that consumes electricity. This is a type of party connected to the grid.

Consumption responsible party

A party who can be brought to rights, legally and financially, for any imbalance between energy bought and consumed for all associated metering points. This is a type of balance responsible party

Grid Operator A party that operates one or more grids. This role is sometimes called Distribution system operator.

Imbalance settlement responsible

A party that is responsible for settlement of the difference between contracted and realised quantities of energy products for the balance responsible parties in a market balance area.

Market operator The unique power exchange of trades for the actual delivery of energy that receives the bids from the Balance Responsible Parties that have a contract to bid. The market operator determines the market energy price for the market balance area after applying technical constraints from the system operator and the bilateral trade schedules from the Balance Responsible Parties.

Metered data aggregator A party responsible for the establishment and qualification of metered data from the Metered data collectors. This data is aggregated according to a defined set of market rules.

Party connected to grid A party that contracts for the right to consume or produce electricity at a metering point.

Producer A party that produces electricity This is a type of party connected to the grid.

Production responsible party

A party who can be brought to rights, legally and financially, for any imbalance between energy sold and produced for all associated metering points. This is a type of balance responsible party.

System operator A party that is responsible for a stable power system (including the organisation of physical balance) through a transmission grid in a geographical area. The SO will also determine and be responsible for cross border capacity and exchanges. Transmission as mentioned above means "the transport of electricity on the extra high or high voltage network with a view to its delivery to final customers or to distributors. Operation of transmission includes as well the tasks of system operation concerning its management of energy flows, reliability of the system and availability of all necessary system services." (Definition taken from the UCTE Operation handbook Glossary). Note: additional rules may be imposed through local market rules.

Trade responsible party A party that is selling and buying energy on a firm basis (a fixed volume per market time period). They should have a zero balance position before settlement. A power exchange without any privileged responsibilities acts as a trade responsible party This is a type of balance responsible party

The detailed role model is to be found in the Appendix. 2.3.3 ETSO Identification Code (EIC) Electronic Data Interchange in the European Electricity Market needs common identification schemes to be effective. Market Agents (Traders, producers, and qualified consumers) have the possibility to act in different TSO areas and TSOs have to exchange information amongst themselves concerning the market players in question. In order to do this a reliable identification scheme is necessary. The primary objects that need to be identified are:

Parties: TSOs, traders, producers, big consumers, power exchanges, grid operators, suppliers, agents and service providers Areas: Local grids where metering points are situated, balance areas consisting of a

number of local grids and control areas Metering Points: For production units, consumers cross border connections, etc. Unit: An entity whose generation or consumption is recorded at a metering point

The identification scheme is based on a fixed 16 length alphanumeric code: Two characters: Issuing Office, One character: Object (Party, Area, Metering, etc.), Twelve characters: Object code, One character: Check character.

Sixteen countries have already opened an ETSO Local Issuing Office to deliver a European Identification code to market participants and to domains. The ETSO Central Issuing Office manages about 1,000 EIC codes. It should be noted that two organisations EFET (European Federation of Energy Traders) and Edig@s (European Gas Utilities) have also implemented Issuing Offices. The list of the Issuing Offices is to be found in the Appendix.

2.4 Implementation Guides Opening of the electricity market has led to a tremendous growth of exchange between existing and new market actors, System Operators, Power Exchanges, Distribution Operators, Power Generators, Suppliers, Traders, Data Collectors, etc. Where this information was historically exchanged between different processes within a utility, now the same information is exchanged between different market actors. ETSO TF 14 has broken the market operations down into three phases: A planning phase, where balance responsible parties (e.g. trade responsible, production

responsible, consumption responsible parties, etc.) calculate in advance the consumption/production of all involved parties for the day ahead. At the conclusion of this phase the system operator informs each balance responsible party of what has been accepted of their schedules and informs the entity responsible for imbalance settlement, called the “imbalance settlement responsible” of all the schedules in question. An operation phase, where the schedule that has been determined during the planning

phase (finalised schedule) is executed. The system operator, to ensure system balance at any moment, handles any deviations between production, consumption and unforeseen congestion.

A settlement phase, where following the date of operation, the metered data aggregator sends the data to the imbalance settlement responsible. The imbalance settlement responsible, along with complementary data received from other sources, then carries out the imbalance settlement itself.

Currently two phases have been investigated by ETSO TF 14 and have resulted in the issuance of two implementation guides, the planning and settlement phases. The purpose of these guides are to make it possible for software vendors to develop an IT application for market players that can exchange information to all related parties in all countries. 2.4.1 ETSO Scheduling System (ESS) An implementation guide was developed for the ETSO Scheduling System (ESS). The initial conception of the guide has been based on the day ahead energy scheduling process in order to obtain a more generic specification of schedule process management. This process is very

closely related to other processes such as imbalance settlement, other scheduling processes, cross border tariffs, capacity allocation, etc. The guide is targeted basically towards business-to-business application interfaces using the full power of the acknowledgment process. However, it may be equally put into place in a more user orientated fashion through a web-based service where the key elements of the acknowledgement process are implicit in the service itself. The roles involved in this process are shown in the Appendix. 2.4.2 ETSO Settlement Process (ESP) A central part of any national legal requirement in the electricity market is that each party in the market shall be in balance. This means that the quantity of electricity produced and/or consumed must be equal to the quantity contracted in the market. The procedure to calculate any imbalance between what is contracted to, contracted from and what is really consumed/produced by a balance responsible party and the invoicing of any differences is called “imbalance settlement”.

ETSO TF 14 describes the document to carry out the exchange of information between the different parties involved in this process. The roles involved in this process are shown in the Appendix. 2.4.3 Status of Implementation The success of ETSO TF 14 products can be measured through the implementation of the ETSO recommendations. The status of implementation is the following: 2001: “Proof of Concept” of ESS in Belgium, France and Switzerland. 2001/12: Implementation of ESS v0.3 in France for Over The Counter (OTC)

transactions between Balance Responsible Parties. 2002/06: Implementation of ESS v1.0 in Hungary. 2003/12: Implementation of ESS v2.3 in Austria for all the schedules. 2004/06: Implementation of ESS v2.3 in Germany, Luxembourg and Switzerland for all

the schedules.

2004/07: Pilot Project of implementation of ESP v1.0 in France for exchange between Distribution Utilities and RTE and implementation of ESS v2.3 in France for the schedules between Balance Responsible Party and End-Consumer in Distribution Area. 2004/09: Implementation of ESS v2.3 in Poland for the international trade schedules.

2.4.4 Future Work As stated earlier the market operations were broken into three phases. ETSO TF 14 has started in December 2004 to work on the “operation phase”, i.e., the business process and documents related to the balance management.

The ETSO Reserve Resource Planning System

Al l actors that may play in the supply of primary, secondary and tert iary reserve have their units qualified by the TSO and if accepted are contracted as actors in the market

The TSO based on internal plans may tender out resource requirements. (e.g. on an annual basis - primary reserve, on a half yearly basis : secondary reserve and on a daily basis tertiary reserve

During the day ahead planning cycle the necessary reserves are ident ified to ensure network security taking into account technical constraint requirements

During operat ion Modified Unit reserve schedules may be provided for planning update. Addit ional tertiary resources may be act ivated as required.

At the end of the day resource usage is identified and any divergences with the planned resources are settled

The dark coloured use cases are the focus of the project

The above diagram outlines the different processes that are generally carried out within such markets. The focus of this new project is on the planning of reserve requirements from different resources that take place both during the day ahead planning phase and the operational phase where the initial plan has to be updated to cater for unforeseen events. One of the technical issues to be resolved at this level is ensuring that the market participant only sells the quantity of reserve that his qualified units are capable of supplying. The focus of this current project is on the use cases where resource requirements are planned. Within this process there are basically two roles participating:

The market participant who may in one case be supplying the reserves and in another case may be providing the daily market schedules of consumption and generation. The TSO who has to ensure that the network under its responsibility is capable of

ensuring the market requirements and satisfying its security requirements. In this context there may be TSO-TSO interactions.

3 Appendix 3.1 Implementation of ETSO Rules in Austria by Dr. Peter Bauhofer, A&B, Innsbruck Together with EURELECTRIC, EFET and ebIX, ETSO plays an important role for the harmonisation of data processes in the liberalised European electricity industry. National and international differences between data formats, processes in data interchange and quality management as well as the lack of common rules for identification and registration of market participants are considered to be the major handicaps for a well working liberalised market on an international basis. Since 1999 Austria has liberalised its electricity market step-wise. On October 1st, 2001 the market was open also for mass-customers on basis of a regulated grid access and a balance group system. From the very beginning on it was the goal to create almost complete market rules with detailed definitions for data processes and interchange. To guarantee a market start without any frictions and to avoid costs for new IT-systems it was important that all data processes could be done with the help of existing and proofed tools. The German KISS-EXCEL format for scheduling and the German EDIFACT/MSCONS-Format for metered data exchange were the key to a successful market start. Within a few months Austrian electricity market has become more and more international. Having started with 15 balance responsible parties in 2001, 41 are registered today and they getting more with the entrance of new countries to the European Community. It was a great first step when ETSO suggested in autumn 2002 to introduce with the EIC (ETSO Identification Coding Scheme) a common rule to identify balance responsible parties and further on balance groups all over Europe. This coding and registration have been done by the national ELIO (ETSO Local Issuing Offices) that are cooperating very closely with the ECIO (ETSO Central Issuing Office) in Brussels. Data interchange between ELIO and ECIO is done on basis of XML only. Together with Germany, Switzerland and Luxemburg Austria has introduced the registration and scheduling process on basis of EIC successfully in April 1rst 2004. EIC has proofed as a very practicable solution. After the introduction of EIC, the work of ETSO TF 14 succeeded in a suggestion for a common scheduling system based on XML standard: ESS (ETSO Scheduling System) was born. The introduction of this new system meant a lot of changes at the IT-systems of market participants in the Austrian market rules. Reflecting the ETSO papers in the 1st quarter of 2002 an experts’ group was formed together with the Austrian Association of Electricity Utilities (VEÖ) and the Austrian regulator. As an advantage of the regulated market system it was possible to introduce ESS in Austria within a very short time. Market rules were finished in May, ESS testing started on June 1st and the operational introduction was done from July 1st until December 2nd, 2003. Austrian imbalance settlement responsible parties and TSOs played a key role at the preparation and introduction of EIC and ESS. Imbalance Settlement is a central business process in a market system on basis of balance groups. Since 2001, in Austria imbalance settlement and reconciliation are working very successfully. It is a great honour, that Austria’s experts of the imbalance settlement

responsible parties are introduced to contribute their experiences in ETSO TF 14 in particular with an international focus on data quality management. The current status of work gives hope, that also this ETSO-expertise of the imbalance settlement project will give another fundamental process rule for a common European market within the near future.

3.2 Implementation of ETSO Rules in France by Mr. Marc Berrier, RTE, France Since 1999, France has opened its electricity market on a step by step basis following the European Directive: 1999: eligible sites (about 500) having more than 16GWh of consumption, i.e., about

30% of the total load; 2002: eligible sites (about 1,000) having more than 9GWh of consumption; 2003: eligible sites (about 3,100) having more than 7GWh of consumption about 37.5%

of the total load; 2004: eligible sites (about 3.5 Millions) for all industrial consumers about 75% of the

total load; 2007: all end consumers.

To enable the opening of the electricity market, RTE has very early on developed the activities related to “over the counter” (OTC) exchanges. To make the OTC market more fluid, RTE decided in September 2001 to implement data exchanges with the Balance Responsible Parties using ETSO ESS recommendations (version 0.3). This implementation was initially carried out for the day ahead gate closure. This implementation was a success and quickly, RTE was required to open intra day gates. Nowadays, there are up to six intra day gates. The yearly volume of energy exchanges amounts to about 160TWh in 2004. The standardisation of the information exchanges was a key factor in the success of this product. In 2003, RTE contributed actively with ETSO TF 14 to draft the Settlement Implementation Guide, ESP. The definition of the Energy Account Report (EAR) as the XML document to support settlement data exchanges, was another key factor in the successful market opening for industrial consumers. Especially since Distribution Utilities (as Metered Data Aggregator) were involved in the full settlement process. About 200 Distribution Utilities in France have to supply RTE (as Imbalance Settlement Responsible) with all the data relative to the consumption and generation of the Balance Responsible Parties acting on their networks. All these exchanges of information are automated through the use of ETSO ESP Implementation Guide. The standardisation of the information exchanges by ETSO enabled to shorten the discussions with the Distribution Utilities to define the exchange process as well as the document content to be considerably shorten. Although, the ETSO ESP Implementation Guide was only published in March 2004, all the actors were ready by July 1st to supply RTE with the data for the Settlement process. Distribution Utilities were proactive in this implementation as they considered the automation an indispensable value added process. This implementation also required RTE to become an ETSO Local Issuing Office in order to assign ETSO Identification Codes (EIC) not only for the Balance Responsible Parties, but also for Distribution Utilities (as Metered Data Aggregator) and for all eligible customers buying blocks of energy from a Supplier. In addition, EIC codes were defined for each Distribution Utility network. This has led RTE to manage about 400 new EIC codes in addition to the existing EIC codes already provided by other ETSO Local Issuing Offices for their Balance Responsible Parties.

For 2005, RTE will continue to actively support ETSO TF 14 recommendations. One of the major steps will be the move from ESS v0.3 to ESS v2.3 for all the transactions related to OTC market. As a major actor for Import/Export of energy in the Internal European Market, RTE is in discussion with other TSOs to implement ETSO recommendations for cross border transactions. RTE will also actively contribute to the work carried out by ETSO TF 14 in the field of generation schedules taking also into account the already existing work from IEC TC 57 WG 13 (Common Information Model – IEC 61970).
