As one of the Regional Coordination Centres (RCCs), Coreso coordinates high-voltage electricity flows for European Transmission System Operators (TSOs) to support them ensuring the security of electricity supply on a European regional basis.

Our RCC activities consist in performing analyses, recommending and coordinating solutions for TSOs and partners in different areas in Europe. Combining their expertise 24 hours a day, 7 days a week, Coreso engineers do this by anticipating the operations both in the short term and the long term, from a year-ahead until intraday (few hours before real time).

The European electricity system being complex and highly interconnected, Coreso coordination role is essential to help TSOs guarantee a more efficient and secure transmission grid.
The development of renewable energies (which are by nature intermittent) as well as the increase in cross-border exchanges within the European electricity market make electricity flows increasingly variable. They are therefore much more difficult to predict and calculate than in the past. In this area, Coreso has demonstrated and continues to demonstrate daily a significant level of reliability and expertise. Besides, our added value in terms of proactive identification of situations likely to present a risk to the electrical system is critical. Indeed, risks can only be detected by building an overview beyond the national framework of each individual transmission network.

Europe aiming for green transition and digital transformation, Coreso is developing, implementing and delivering the regulated coordination services required by the network codes and the Clean Energy Package (CEP). Enhancing regional coordination, these regulations will enable member states to increase the integration of renewable energies while improving efficiency and competitiveness on the European electricity market.
