Congestion management
This section provides an overview of the congestion management actions performed by Elia, either for its own needs or to support a neighboring TSO

Commission Regulation (EU) n° 543/2013 on submission and publication of data in electricity markets defines the concepts of Redispatching and Countertrading as follows :
- “Redispatching” : Measure activated by one or several system operators by altering the generation and/or load pattern in order to change physical flows in the transmission system and relieve a physical congestion. Further distinction can be made between:
- Internal Redispatching : All redispatching bids are performed in the control area where the congestion is located.
- Cross-Border Redispatching : The redispatching bids are performed in different control areas.
- “Countertrading” : Cross zonal exchange initiated by system operators between two bidding zones to relieve physical congestion.
High level overview of the Channel Redispatching / Countertrading Actions by Elia
In accordance with the Channel CCR methodology for Coordinated Redispatching and Countertrading which requires that each Channel TSO should publish on their respective website a high-level overview of the RD and CT Action that could be activated to restore the balance of their grid after a redispatching/countertrading on a Channel Interconnector (Nemo Link in Elia's case), you will find this overview in this document.
