Modification of the Belgian external constraint

Dear Market Participants,

In our message of 29 May 2018, we informed you that the Belgian External Constraint value for import is adapted from 4500 MW to 5500 MW for the Belgian bidding zone from delivery day 01/06/2018 (day-ahead market coupling 31/05/2018) for the CWE day-ahead Flow-Based market coupling.

In our message of 13 February 2019, we informed you that this Belgian External Constraint value for import is adapted considering the expected physical flow through Nemo Link Interconnector.

Today we inform you that the base value for adapting the Belgian External Constraint value considering the expected physical flow through Nemo Link Interconnector will no longer be 5500MW, but 6000MW.
This change in base value will be made from business day Saturday the 25th of May 2019 onwards and is valid for all time stamps and all days. This change will be applied from delivery day 25/05/2019 (day-ahead market coupling 24/05/2018) for the CWE day-ahead Flow-Based market coupling.

We would like to inform you once again that the Belgian External Constraint used during the CWE day-ahead Flow-Based market coupling can be found via our web site http://www.elia.be/en/grid-data/data-download (Section: data download / Category: “Interconnection” / CWE FB External Constraints).
