The European associations representing the distribution system operators (DSOs) – CEDEC, E.DSO, Eurelectric and GEODE – as well as ENTSO-E, representing the transmission system operators (TSOs), launch a report on the development and integration of new flexibility services in the electricity system and market. These services could support system operators to manage congestions in their grids caused by increased electrification and shares of decentralised resources. Since the same resources can also be used by TSOs, the interaction between congestion management and balancing is discussed in the report. Therefore, TSOs and DSOs propose a vision in their common report “An integrated approach to Active System Management”.
