PROFILE: ENTSO-E

ENTSO-E, the European Network of Transmission System Operators, represents 41 electricity transmission system operators (TSOs) from 34 countries across Europe. ENTSO-E was established and given legal mandates by the EU’s Third Legislative Package for the Internal Energy Market in 2009, which aims at further liberalising the gas and electricity markets in the EU.

ENTSO-E promotes closer cooperation across Europe’s TSOs to support the implementation of EU energy policy and achieve Europe’s energy & climate policy objectives, which are changing the very nature of the power system.

The main objectives of ENTSO-E centre on the integration of renewable energy sources (RES) such as wind and solar power into the power system, and the completion of the internal energy market (IEM), which is central to meeting the European Union’s energy policy objectives of affordability, sustainability and security of supply.

ENTSO-E contributes to the achievement of these objectives mainly through:

• the drafting of network codes
• the development of pan-European network plans (TYNDPs)
• the technical cooperation between TSOs
• the publication of summer and winter outlook reports for electricity generation
• the coordination of R&D plans.

ENTSO-E aims to be the focal point for all technical, market and policy issues relating to TSOs and the European network, interfacing with power system users, EU institutions, regulators and national governments.

Through these deliverables, ENTSO-E is helping to build the world’s largest electricity market, the benefits of which will not only be felt by all those in the energy sector but also by Europe’s overall economy, today and into the future.

ENTSO-E is entirely funded through membership fees paid to the association by its member TSOs.

Member Companies

​​​​European Transmission System Operators (TSOs) are entities operating independently from the other electricity market players and 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.

42 TSOs from 35 countries are members of ENTSO-E (the European Network of Transmission System Operators for Electricity).
