European Market Coupling Company, EMCC or emcc, is a provider of congestion management services for cross-border electrical interconnectors. This is done by means of market coupling, in particular tight volume coupling.

Contents

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. It was established in Hamburg, Germany, in August 2008. [1]

Purpose and functioning

The purpose of EMCC is to promote an efficient electricity market between regions by using market coupling and to promote the integration of a Europe-wide wholesale electricity market.

EMCC calculates optimal electricity flows, based on available transmission capacities (ATC) from the TSOs and anonymous order books (OBK) from the exchanges. Afterwards, EMCC places market coupling bids at the PXs in order to achieve a power flow from the low-price area into the high-price area. Subsequently, EMCC creates schedules and carries out the financial settlement with the PXs. EMCC's calculation algorithm is based on the economic welfare criterion. [2]

Development

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. Baltic Cable between Sweden and Germany was integrated in May 2010. [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. The new scheme is called Interim Tight Volume Coupling (ITVC). It is based on the existing Nordic-German tight volume coupling and is a further enhancement. [5] [6]

On 9 November 2010, day-ahead market coupling for the extended region was launched. This region covers Belgium, France, Luxembourg, Germany, the Netherlands, the Nordic region and Estonia. It represents the world's largest single power market of 1,816 TWh, about 60% of European power consumption. [7] The second step adding the NorNed cable between Norway and the Netherlands started on 12 January 2011. [8]

The TSOs between Finland and Spain are preparing to operate a common electricity market in November 2013, [9] and in May 2014 Spain and Portugal were included. [10] Italy was added in February 2015. [11]

NorNed

NorNed is a 580-kilometre (360 mi) long high-voltage direct current submarine power cable between Feda in Norway and the seaport of Eemshaven in the Netherlands, which interconnects both countries' electrical grids. It was once the longest submarine power cable in the world. Budgeted at €550 million, and completed at a cost of €600m, the NorNed cable is a bipolar HVDC link with a voltage of ±450 kV and a capacity of 700 MW. NorNed is a joint project of the Norwegian transmission system operator Statnett and its Dutch counterpart TenneT. The cable system itself and the two converter stations were produced by ABB.

Submarine power cable Bundle of long-distance wires on the seabed for transmitting electricity

A submarine power cable is a transmission cable for carrying electric power below the surface of the water. These are called "submarine" because they usually carry electric power beneath salt water but it is also possible to use submarine power cables beneath fresh water. Examples of the latter exist that connect the mainland with large islands in the St. Lawrence River.

Estlink

Estlink is a set of HVDC submarine power cables between Estonia and Finland. Estlink 1 is the first interconnection between the Baltic and Nordic electricity markets followed by Estlink 2 in 2014. The main purpose of the Estlink connection is to secure power supply in both regions to integrate the Baltic and Nordic energy markets.

NordBalt

NordBalt is a submarine power cable between Klaipėda in Lithuania and Nybro in Sweden. The purpose of the cable is to facilitate the trading of power between the Baltic and Nordic electricity markets, and to increase the supply and energy security in both markets.

Wind power in Denmark Overview of wind power in Denmark

Denmark was a pioneer in developing commercial wind power during the 1970s, and today a substantial share of the wind turbines around the world are produced by Danish manufacturers such as Vestas—the world's largest wind-turbine manufacturer—along with many component suppliers. In Denmark's electricity sector wind power produced the equivalent of 47% of Denmark's total electricity consumption in 2019, an increase from 43.4% in 2017, 39% in 2014, and 33% in 2013. In 2012, the Danish government adopted a plan to increase the share of electricity production from wind to 50% by 2020, and to 84% by 2035. Denmark had the 4th best energy architecture performance in the world in 2017 according to the World Economic Forum, and the second best energy security in the world in 2019 according to the World Energy Council.

NordLink Power cable between Norway and Germany

NordLink is a subsea 1,400 megawatt (MW) HVDC power cable between Norway and Germany, opened in May 2021. The over 500 kilometres (310 mi) long cable operates at a voltage of 500 kV DC.

Synchronous grid of Continental Europe

The synchronous grid of Continental Europe is the largest synchronous electrical grid in the world. It is interconnected as a single phase-locked 50 Hz mains frequency electricity grid that supplies over 400 million customers in 24 countries, including most of the European Union. In 2009, 667 GW of production capacity was connected to the grid, providing approximately 80 GW of operating reserve margin. The transmission system operators operating this grid formed the Union for the Coordination of Transmission of Electricity (UCTE), now part of the European Network of Transmission System Operators for Electricity (ENTSO-E).

An interconnector is a structure which enables electricity to flow between electrical grids. An electrical interconnector allows electricity to flow between separate AC networks, or to link synchronous grids. They can be formed of submarine power cables or underground power cables or overhead power lines. The longest interconnection as of 2016 was the undersea NorNed link between Norway and the Netherlands, spanning nearly 600 km and delivering 700 MW of high voltage direct current power.

COBRAcable

COBRAcable is a ±320 kV, 700 MW HVDC submarine power cable pair between Eemshaven, the Netherlands and Endrup near Esbjerg, Denmark. The cable is jointly owned by Energinet.dk and TenneT. Its purpose is to improve the European transmission grid and thus increase the amount of variable wind power in the system while improving supply reliability. Its 700 MW capacity corresponds to an annual transmission capacity of 6.1 TWh.

Kriegers Flak is a 600 MW offshore wind farm under construction in the Baltic Sea on the Danish part of the reef of the same name. It will form part of a new 400 MW interconnector between Denmark and Germany.

The government of Denmark is planning to establish two large-scale offshore wind farm projects or "energy islands", one in the North Sea and one in the Baltic Sea, by the year 2030. In the North Sea, an artificial island will be constructed with the capacity to serve as a hub for up to 3 GW of offshore wind farms initially, and potentially up to 10 GW in the future. The artificial island may take the form of a sand island, steel platforms, or a large container lowered into place and filled with stone material, and would be located approximately 80 kilometres (50 mi) west of Jutland, at a water depth of 26–27 metres (85–89 ft). In the Baltic Sea, a hub will be built on the natural island of Bornholm that will be able to serve up to 2 GW of offshore wind farms.
