[TTN] Changes in CNE's for CORE Flowbased

by TenneT TSO BV

Dear Market Participants,

Some time ago a bypass consisting of merging of GT-KIJ380 Z (49T0000000000282) and CST-KIJ380 Z (49T0000000000339) into CST-GT380 Z (49T0000000002226) was realized to enable maintenance and grid upgrades. This has now finished and the old situation has been restored.

This will also result in the addition of the following CNE changes to Flowbased CORE starting on business day 2023-02-04:

* Crayestein-Geertruidenberg 380 Zwart with element name CST-GT380 Z and EIC 49T0000000002226 removed as CNE

* Geertruideberg-Krimpen a/d IJssel 380 Zwart with element name GT-KIJ380 Z and EIC 49T0000000000282 added as CNE

* Crayestein-Krimpen a/d IJssel 380 Z with element name CST-KIJ380 Z and EIC 49T0000000000339 added as CNE

The new CNE's will be added with applicable contingencies.

We trust to have informed you sufficiently.
