The European Network of Transmission System Operators for Electricity (ENTSO-E) is an association of Europe's transmission system operators (TSOs) for electricity. It is a successor of ETSO, the association of European transmission system operators founded in 1999 in response to the emergence of the internal electricity market within the European Union.

History[edit]

On 27 June 2008, 36 European electricity transmission system operators (TSO) signed in Prague a declaration of intent to create the ENTSO-E.[1] ENTSO-E was established on 19 December 2008 in Brussels by 42 TSOs as a successor of six regional associations of the electricity transmission system operators.[2][3] ENTSO-E became operational on 1 July 2009. The former associations ETSO, ATSOI, UKTSOA, NORDEL, UCTE and BALTSO became a part of the ENTSO-E, while still offering data by their predecessors for public interest.[4]

Initiation[edit]

Creation of ENTSO-E was initiated by the adoption of the European Union third legislative package on the gas and electricity markets.[1] In 2003, the European Commission conducted a sector inquiry concerning the competition of electricity market in six European countries.[5] Examining competition in these countries, the final report stated serious issues to be solved.[6] It was noticed that the integration between member state's markets is still insufficient. Additionally, the absence of transparently available market information was assessed.[5] As a result, the third legislative package on the EU gas and electricity markets was adopted by the European Commission in September 2007.[7]

Main tasks[edit]

  • Elaboration and establishment of network codes[8]
  • Ensure coordination of network operation by common network operation tools[9]
  • Develop a ten-year network development plan[10]
  • Publish annual work programme, annual report and annual summer and winter generation adequacy outlooks[11]

Objectives[edit]

  • Security of supply[12][13]
  • Meeting the needs of the Internal Energy Market and facilitating market integration[14]
  • Promotion of relevant R&D and the public acceptability of transmission infrastructure[14]
  • Consultation with stakeholders and positions towards energy policy issues[14]

Members[edit]

The ENTSO-E now contains 41 TSOs from 34 countries, which now share an interconnected transmission grid in the EU.[15]

Regional structure[edit]

ENTSO-E is divided into five regional groups and 2 voluntary Regional Groups (Northern Europe and Isolated Systems), which derive from the historic background of the former associations.

Continental Europe[edit]

The regional group of Continental Europe includes the former members of the Union for the Co-ordination of Transmission of Electricity (UCTE). The UCTE was founded in 1951 as the Union for the Coordination of Production and Transmission of Electricity consisting of an interconnected companies from Switzerland, France and Germany. Over the time, most of TSOs of Continental Europe joined the association. In 1999, UCTE re-defined itself as an association of TSOs. Before merging to ENTSO-E, UCTE represented 29 transmission system operators of 24 countries operating the synchronous grid of Continental Europe.[16]

Ireland[edit]

The region of Ireland consists of EirGrid and System Operator for Northern Ireland (SONI), the former members of the Association of the Transmission System Operators of Ireland (ATSOI).[17]

United Kingdom[edit]

The region of the United Kingdom consists of the TSOs of the United Kingdom, former members of the UK Transmission System Operators Association (UKTSOA).[18]

Nordic[edit]

The Nordic region consists of Finland, Sweden, Norway and Eastern Denmark, the former members of the Nordic TSO association NORDEL. NORDEL was founded in 1963 for co-operation between the TSOs of Denmark, Finland, Iceland, Norway and Sweden for a further development of an harmonized Nordic electricity market.[19]

Baltic[edit]

The Baltic region consists of Estonia, Latvia and Lithuania. Before creation of the ENTSO-E, the Baltic TSOs were members of the Baltic Transmission System Operators association (BALTSO). BALTSO was founded on 30 March 2006.[20]

Northern Europe[edit]

The members of the Voluntary Regional Group Northern Europe (VRG NE) are the following TSOs:[21]

- Denmark (East): Energinet.dk

- Finland: Fingrid OyJ

- Germany: TenneT TSO GmbH (corresponding member)

- Germany: 50Hertz Transmission GmbH (corresponding member)

- Netherlands: TenneT TSO B.V.

- Norway: Statnett SF

- Poland: PSE Operator S.A.

- Sweden: Affärsverket Svenska Kraftnät

Isolated Systems[edit]

The members of the Voluntary Regional Group Isolated Systems (RG IS) are the following TSOs:[22]

- Cyprus: Cyprus Transmission System Operator

- Iceland: Landsnet hf

- Italy: Terna - Rete Elettrica Nazionale SpA

- Spain: Red Eléctrica de España: S.A.

Frequency[edit]

In order to ensure a working European power grid, the operating frequency is defined by a standard of 50 hertz. As electric generation and consumption differs, the power transmission grid has to be balanced. There should be the same amount of input and output. Nevertheless changes in the frequency may occur if supply or demand exceeds its counterpart. In case of too much supply the frequency will increase, while in case of too much demand it will decrease. The main task is to keep the frequencies of all five synchronous areas balanced around the 50 hertz standard to ensure a safe power supply.[23]

Electronic data interchange[edit]

An open European electricity market needs a considerable electronic data interchange between all market participants in order to improve the coordination between different inter-country systems. The aim of the ENTSO-E is to offer all participants the necessary information of the existing EDI standards and their specifications. In association with ebiX and EFET (European Federation of Energy Traders) ENTSO-E maintains a Harmonised role model for the European electricity market.[24]

System development[edit]

The ENTSO-E will publish a ten-year network development statement, which ought to ensure the reliability and security of electric energy supply in Europe. An adequate grid should be available for the functioning of the European electricity market. The committee will introduce technical rules and standards related to the planning of transmission systems and new technical concepts within R&D-activities. Furthermore it will focus on facilitating the exchange of information about efficient asset management, system technology and critical infrastructure protection among members. In order to fulfill its duties and tasks, the committee will investigate and develop long-term and medium-term system extension strategies, draw system studies and collect data relevant for system development.[25]
