Since its launch, the BELPEX DAM was coupled with the two neighbouring Power Exchanges, APX in the Netherlands and EPEX Spot (formerly Powernext) in France.
In this Trilateral Market Coupling (TLC) the Power Exchanges implicitly made available the daily cross-border capacity between the Netherlands, Belgium and France. This capacity was provided by the Transmission System Operators Elia, RTE and TenneT.
The TLC has proven very successful in optimizing the use of the daily cross-border capacity and has been replaced by the CWE market coupling as of 9 November 2010.
Possible market outcomes from coupling France, Belgium and the Netherlands
Given the fact that the Trilateral Market Coupling involved two cross-border connections (FR-BE and BE-NL) which individually could be unconstrained coupled or constrained coupled, three possible market outcomes could be considered:

The basic concept of market coupling is explained on this page.
A more in-depth information on the market coupling concept can be found in the Trilateral Market Coupling Algorithm Appendix, which is annex to the Belpex Market Segment Procedure and can be found via this link.
Belpex' partners in the Tri-lateral Market Coupling concept were:
