Redispatching [13.1.A]

Congestion management – redispatching
Regulation Article	TR article 13.1.a
Regulation text	Information relating to redispatching per market time unit, specifying: – the action taken (that is to say production increase or decrease, load increase or decrease); – the identification, location and type of network elements concerned by the action; – the reason for the action; – capacity affected by the action taken (MW).
Detailed description	For their control areas TSOs shall provide to ENTSO-E for publication: Information relating to redispatching per market time unit[1], specifying: - The action taken (the action consists of a list of production  increases or decreases, and if applicable a list of load increases or decreases); - The identification, location  and type of network elements (type of asset; concerned by the action); - The identification of the connecting TSO - The reason for the action (2 possibilities): “Load flow overload” (current problem), “Voltage level adjustment”; - Redispatched energy (MWh) resulting from changes of affected generation/load capacity. - The control area where energy is going - The control area where energy is taken from - the start and end date (day, hour) of the action; - comments. Although the Transparency Regulation requests the “capacity affected by the action taken (MW)”, ENTSO-E has decided to publish redispatched energy for generation and/or for load in MWh (energy rather than capacity) in order to improve the quality of the publications. Note: Action taken by TSO or TSOs who change the generation/load pattern [1]With regards to the internal redispatching, the information pertaining to congestion management measures in self-dispatch systems will be published. The information relating to congestion management measures in central dispatch systems (i.e. Italy, Poland, Greece, Ireland and Northern Ireland) cannot be published because it is not possible to distinguish between balancing and congestion management which are performed simultaneously.
Specification of calculation	The redispatched energy (MWh) resulting from changes of affected generation/load capacity is provided by separate publication for volumes of a) generation increase, b) generation decrease, c) load increase or d) load decrease i.e. the aggregated sum of generation/load increases separate from the aggregated sum of generation/load decreases. The identification, location and type of network elements concerned, i.e. the location of congestion causing the need for redispatch is provided by specifying the EIC of concerned network element as soon as the information becomes available. It may optionally be submitted at H+1 and should be updated on D+1.
Primary owner of the data	TSOs (either the initiator of the action or responsible TSO for its control area must send the information to the transparency platform)
Data provider	TSOs (the initiator of the action must send the information to the transparency platform)
Aggregation	No
Publication deadline for ENTSO-E	The information shall be published as soon as possible but no later than 1 hour after the operating period.
Updates	Yes
