The European Network of Transmission System Operators for Electricity speaks for all electric TSOs in the EU and others connected to their networks, with one voice for all regions, and for all their technical and market issues.

Transmission System Operators (TSOs) are responsible for the bulk transmission of electric power on the main high voltage electric networks. TSOs provide grid access to the electricity market players (i.e. generating companies, traders, suppliers, distributors and directly connected customers) according to non-discriminatory and transparent rules. In order to ensure the security of supply, they also guarantee the safe operation and maintenance of the system. In many countries, TSOs are in charge of the development of the grid infrastructure too. TSOs in the European Union internal electricity market are entities operating independently from the other electricity market players.

On 27 June 2008, 36 European electricity transmission system operators (TSO) signed in Prague a declaration of intent to create the ENTSO-E.

The 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.

The 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.

1. ATSOI - Association of the Transmission System Operators of Ireland

On 01 July 2009 ATSOI was wound up.

All operational tasks were transferred to ENTSO-E

2. BALTSO - Baltic Transmission System Operators

On 01 July 2009 BALTSO was wound up.

All operational tasks were transferred to ENTSO-E.

3. ETSO - European Transmission System Operators

On 01 July 2009 ETSO was wound up.

All operational tasks were transferred to ENTSO-E.

4. Nordel

On 01 July 2009 Nordel was wound up.

All operational tasks were transferred to ENTSO-E.

5. UCTE - Union for the Coordination of the Transmission of Electricity

On 01 July 2009 UCTE was wound up.

All operational tasks were transferred to ENTSO-E.

6. UKTSOA - UK Transmission System Operators Association

On 01 July 2009 UCTE was wound up.

All operational tasks were transferred to ENTSO-E.

In conclusion Europe’s electricity consumption is almost 3000 TWh per 1 year!

In Europe are near upon 500 milion consumers!The cost of electricity for 1 year is ≥ 240.000.000.000 Euro!

Elaboration and establishment of network codes

Ensure coordination of network operation by common network operation tools

Develop a ten-year network development plan

Publish annual work program, annual report and annual summer and winter generation adequacy outlooks

Security of supply

Meeting the needs of the Internal Energy Market and facilitating market integration

Promotion of relevant R&D and the public acceptability of transmission infrastructure

Consultation with Stakeholders and positions towards energy policy issues

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.

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 Harmonized role model for the European electricity market

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.
