Published:

TSO(s) *:
50Hertz and Energinet

 

Identification of affected Long Term Transmission Rights
DK2-DE/Kontek and cable 154 between the head end platform of the offshore wind farm (OWF) Baltic 2 to the head end platform of the OWF Baltic 1 with both OWFs being connected to the Kriegers Flak Combined Grid Solution

 

Triggering event :
Cable outages.

 

☒Curtailment to ensure operation remains within Operational Security Limits​
☐Curtailment due to Force Majeure
☐Curtailment due to emergency situation
 

Affected volume in MW / hour for each concerned period :
On the border D2->DE, 240 MW Yearly and Monthly capacities for each hour over the whole curtailment period from 20-12-2020, 00:01 hrs. until 22-12-2020, 18:00 hrs.  

On the border DE->D2, 40 MW Yearly and Monthly capacities for each hour over the whole curtailment period from 20-12-2020, 00:01 hrs. until 22-12-2020, 18:00 hrs.  

  

Amount of LTTR remaining after curtailment :
On the border D2->DE: 0 MW

On the border DE->D2: 200 MW

 

Information on exact operational security limit(s) that are expected to be violated in the absence of curtailment *:
There is no alternative to the curtailment of the affected LTTRs.

Since 15 December 2020, the border DK2-DE is formed jointly by KONTEK and the Kriegers Flak Combined Grid Solution (KF CGS) and all the capacity on KF CGS that is not required for transporting the offshore wind power generated and fed-in by the German offshore windfarms Baltic 1 and Baltic 2 to the onshore transmission grid of 50Hertz, will be made available for cross-border electricity trade between Germany and Denmark, while maintaining operational security limits. A reliable and accurate forecast of the wind generation by the German OWFs can be made only on a day-ahead basis.

KONTEK continues to be completely unavailable until 22 December 2020, 18:00 hrs. and KF CGS has become partly unavailable on 17 December where each unavailability is due to a forced technical outage.
