The Mesh-Up: ENTSO-E and European TSO Cooperation in Operations, Planning, and R&D

The 41 European electricity transmission system operators (TSOs) from 34 countries across Europe are gathered under the umbrella of the European Network Transmission System Operators for Electricity (ENTSO-E) cooperative association to support security of supply, sustainability, and the development of a European internal energy market. Together they provide transmission service to 534 million citizens. Their cooperation is regulated by European Union (EU) Regulation (EC) 714/2009 on cross-border exchanges of electricity. As such, ENTSO-E is the focal point for all technical, market, and policy issues relating to TSOs and the European network; it interfaces with power system users, EU institutions, regulators, and national governments.
