A leading role in European cooperation

RTE plays a key role in consolidating Europe’s energy market within an ecosystem of partners. In the forefront: its fellow transmission system operators (TSOs), all forming part of ENTO-E (European network of transmission system operators for electricity) and the Coreso technical coordination centre. The purpose of this coordination is to build and coordinate the operation of a robust and integrated European power system. In the leading position of Europe’s biggest high and ultra-high voltage network, RTE also works very closely together with electricity stock exchanges to coordinate cross-border exchanges. It is involved in numerous R&D programmes run in conjunction with European research centres and industrialists.

ENTSO-E: working together to build a secure and integrated system

RTE has been closely involved in the founding and running of ENTSO-E, the European network of transmission system operators for electricity. Founded in 2009 and given legal mandates by the Europe’s third energy package, ENTSO-E comprises 42 TSOs from 35 countries, going beyond the borders of the European Union. Hervé Laffaye, RTE’s deputy director in charge of international and European business, was appointed President of the ENTSO-E assembly in February 2019. His mandate, which began in June 2019, runs for two years.

ENTSO-E’s mandates, strengthened by the "Clean energy for all Europeans" package, include a number of major projects:

  • Support with the development of network codes. These codes are required in order to operate the synchronous power system on a continental scale, i.e. at the same 50-Hz frequency, to set up the internal energy market by establishing harmonised rules for all member states in areas ranging from grid operation and energy market coordination to the connection of generation and demand-side-response assets.
  • Preparation of the Ten-Year Network Development Plan (TYNDP), an essential tool for determining projects of mutual interest (PMI) and for developing cross-border infrastructures.
  • Development of IT systems supporting the transparency and coordination of a secure operating system for European electricity networks. 
  • Development of an integrated R&D roadmap that guides TSO projects towards the targets set by the European Union. These projects seek to address the essential need for the reduction of greenhouse gases. They also include grid security, sound market practices and the integration of new energy sources.

Coreso: coordinating grid operations

On the 4th of November 2006, the failure of a high-voltage line in Germany plunged about 15 million households into the dark, both in Germany and across the continent’s synchronous regions, more specifically in France and Spain. In order to better prepare for the grid security analyses and prevent such incidents, RTE and its Belgian counterpart Elia decided to set up Coreso, a technical coordination centre, which was then joined by the British, German and Italian TSOs. CORESO now consists of 9 TSOs (RTE, ELIA, NGSO, EirGRID, Soni, 50hz, TERNA, REE, REN). Other regional coordination centres were established right across Europe, driven by the European network codes.

Its goal: Coordinated analysis of power flows across Central Western Europe. Every day, CORESO works closely together with its members and the other regional centres in order to maximise interconnection capacities at the borders and to produce reliable security analyses on cross-border effects between the different national grids. This need is even greater in a single market, where measures must be taken to ensure that exchanges remain compatible with system security.

The “Clean Energy for all Europeans” package has brought about changes to the regional cooperation centres’ model. Renamed “regional coordination centres”, these structures will now operate within geographic areas known as “system operation regions”, currently being determined in accordance with the “Clean Energy” package.
