Capacity Curtailment on the border D2 -> DE from 18 to 22 December 2020 and on the border DE -> D2 from 18 to 21 December 2020
50Hertz and Energinet
Identification of affected Long Term Transmission Rights
DK2-DE/Kontek.
Triggering event :
Cable outage.
☒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, 176 MW Yearly and Monthly capacities for each hour over the whole curtailment period from 18-12-2020, 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 18-12-2020 until 21-12-2020, each day from 06:01 hrs. to 19:00 hrs.
Amount of LTTR remaining after curtailment :
On the border D2->DE: 64
On the border DE->D2: 200
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 not available until 22 December 2020, 18:00 hrs. due to an forced technical outage, whereas KF CGS will be only partly available from 18 to 21 December 2020, each day from 06:01 to 19:00 hrs. due to installation works in the proximity of the cables running between the German offshore wind farm Baltic 2 and the future Danish offshore wind farm Kriegers Flak.
Why alternative measures are not sufficient to avoid the expected violation of operational security limit(s) *?
