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.
