ENTSO-E is the European Network of Transmission System Operators for Electricity. ENTSO-E coordinates the cross-border system operations, system development and electricity market activities of 42 electricity transmission system operators (TSOs) which cover 35 countries. 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 legal mandates include the Europe-wide electricity network development plans, network codes and the transparency platform.

The ENTSO-E Secretariat in Brussels is focal point for technical, market and policy questions for all European TSOs in their cooperation with each other, in their joint fulfilment of their legal mandates, and in the intensive interactions with European Commission, regulatory agencies, associations representing network users and other stakeholders. The ENTSO-E Secretariat is a multinational team of more than 70 staff, including secondments from member companies.

The role of the TSOs and their cooperation in ENTSO-E is crucial to ensuring security of supply; completing the largest and most competitive electricity market in the world; and successfully introducing large volumes of renewable energy into the system. The scope and diversity of ENTSO-E’s work has grown rapidly and is expected to grow further with implementation of network codes and the EU’s Energy Union. The Advisor we are seeking will contribute to this further substantial development of ENTSO-E’s work.
