European Market Coupling Company
European Market Coupling Company, EMCC or emcc, provides congestion management on cross-border high-voltage lines in the area of transport network level. EMCC operates for one type of market coupling, the Tight Volume Coupling.
EMCC is a joint venture of the following transmission system operators ( TSOs ) and power exchanges ( PXs ) in North-West Europe: Energinet.dk, TenneT TSO, 50 Hertz Transmission, European Energy Exchange and Nord Pool Spot. EMCC was founded in August 2008 in Hamburg.
Object and function
Due to the market coupling EMCC supports an efficient, region -wide electricity market and promotes the integration of a Europe-wide wholesale electricity market.
EMCC calculates the optimal load flow on cross-border high-voltage lines. The calculation is based on the available capacity (ATC, Available Transmission Capacity) of the TSOs and the anonymous order books ( OBK, Order Book) of the stock exchanges. Subsequently, EMCC independent bids on the involved exchanges to a current flow from the low-price field to achieve the high-price area. Finally EMCC not create the schedules and executes the financial settlement with the stock exchanges through. EMCCs calculation algorithm is based on the principle of economic welfare.
Development
The market coupling on two high-voltage lines between Denmark and Germany / Austria was first launched in 2008 and stopped because the algorithms used by the stock exchanges and EMCC were not sufficiently coordinated again after ten days.
In November 2009, the Danish- German market coupling was successfully resumed with a convex optimization algorithm. Baltic Cable between Sweden and Germany / Austria was incorporated in May 2010.
In January 2010, EMCC was commissioned by the TSOs and exchanges in Central Western Europe ( CWE, Central Western Europe) and Scandinavia, to develop a system to integrate the CWE price coupling with the market splitting in the Nordic market. This new system is called the Interim Tight Volume Coupling ( ITVC ). It is based on the previous German - Scandinavian market coupling and represents an extension and improvement of the EMCC algorithm dar.
On 9 November 2010 the market coupling was started for the entire region with Belgium, France, Luxembourg, Germany, Austria, the Netherlands, Scandinavia and Estonia. With 1,816 TWh, it represents the world's largest integrated electricity market and covers about 60 % of Europe's electricity needs. The second step included the NorNed cable between Norway and the Netherlands was put into operation on January 12, 2011.
