ENTSO-E, the European Network of Transmission System Operators for Electricity, represents 42 electricity transmission system operators (TSOs) from 35 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.

The role of Transmission System Operators has considerably evolved with the Third Energy Package. Due to unbundling and the liberalisation of the energy market TSOs have become the meeting place for the various players to interact on the market place.


ENTSO-E members share the objective of setting up the internal energy market and ensuring its optimal functioning, and of supporting the ambitious European energy and climate agenda. One of the important issues on today’s agenda is the integration of a high degree of Renewables in Europe’s energy system, the development of consecutive flexibility, and a much more customer centric approach than in the past.

ENTSO-E is committed to develop the most suitable responses to the challenge of a changing power system while maintaining security of supply. Innovation, a market based approach, customer focus, stakeholder focus, security of supply, flexibility, and regional cooperation are key to ENTSO-E’s agenda.

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

Through these deliverables, ENTSO-E is contributing 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 aware that such important tasks go hand in hand with a strong interaction with European institutions, ACER, and indeed as well with stakeholders.

Transparency is a key principle for ENTSO-E, and requires a constant listening, learning and improvement, in the interest of society.
