2- Impact of RE integration on operational processes within the Elia TSO (adequacy and congestion management)

3- Flexibility of the electrical system in the context of RES integration: needs and different means

4- Flexibility of the power system in the framework of RES integration: role of interconnections and regional integration: Regional integration of the European balancing model

5-Stability analysis for a system with a high RE shares

6-Role of new technologies in a context of RE integration: impact and necessary studies

7- Political role and positioning of the TSO as a trusted actor in the context of energy transition

The final session served to recall the main conclusions, key elements and lessons learnt on the local impact and definition of TSO priorities.
