The European Day-Ahead Market Successfully Coupled


Today, ČEPS and OTE (in cooperation with other European nominated electricity market operators
and transmission system operators of the Interim Coupling project) successfully implemented
implicit cross-border transmission capacity allocation on the German, Austrian and Polish border.
Selling/buying electricity and securing the necessary cross-border transmission capacity will now
be done in a single process, which will make international electricity trading more effective and
will increase the liquidity of European day-ahead markets.

Until June this year, European day-ahead markets were operated as two separate coupled market areas
(MRC and 4M MC). In order to make a cross-border trade, one had to secure cross-border transmission
capacity and the electricity itself in two different places (so-called explicit auction). By implementing the
Interim Coupling project, explicit auctions were replaced by implicit allocation at six new borders (PLDE,
PL-CZ, PL-SK, CZ-DE, CZ-AT, HU-AT). Selling/buying electricity and securing the necessary crossborder
transmission capacity will now be done in a single process for all bidding zones of the project and
their respective borders. This marks a major milestone in the day-ahead market coupling, as bidding
zones of almost all EU Member States (including Norway) are now coupled.
