European Market Coupling Company

EMCC is a joint venture of the following transmission system operators (TSOs) and electricity exchanges (PXs) in North-Western Europe: Energinet.dk, TenneT TSO GmbH, 50Hertz Transmission GmbH, European Energy Exchange AG, Nord Pool Spot AS.

EMCC calculates optimal electricity flows, based on available transmission capacities (ATC) from the TSOs and anonymous order books (OBK) from the exchanges.

[2] Market coupling on two interconnectors between Denmark and Germany first started in 2008 and was stopped after ten days as it became clear that the algorithms used by EMCC and the PXs were not perfectly aligned.

[3] Danish-German market coupling was relaunched successfully in November 2009 with a revised convex optimiser as algorithm.

[4] In January 2010, EMCC was asked by TSOs and PXs in the Central Western European (CWE) and Nordic region to develop a system to integrate CWE price coupling and Nordic market splitting.
