In addition to the above named, submarine interconnectors Denmark has 400 kV, 220 kV and 150 kV AC transmission cables from Jutland to Germany. These cables can import 1,500 MW and export 1,780 MW of power. Denmark also has four AC (two 132 kV and two 400 kV) submarine cables connecting Zealand with Sweden. These can import 1,300 MW and export 1,700 MW of power. [2] [3] [4]

<span class="mw-page-title-main">Kontek</span> HVDC connector between Germany and Denmark

The Kontek HVDC is a 170-kilometre (110 mi) long, monopolar 400 kV high-voltage direct current cable between Germany and the Danish island Zealand. Its name comes from "continent" and the name of the former Danish power transmission company "Elkraft", which operated the power grid on the Danish islands Lolland, Falster and Zealand and had the abbreviation "ek". As of today, the cable is operated by Energinet.dk in Denmark and 50Hertz Transmission GmbH in Germany.

<span class="mw-page-title-main">Baltic Cable</span>

The Baltic Cable is a monopolar HVDC power line running beneath the Baltic Sea that interconnects the electric power grids of Germany and Sweden. Its maximum transmission power is 600 megawatts (MW).

<span class="mw-page-title-main">Skagerrak (power transmission system)</span>

Skagerrak is the name of a 1,700 MW high-voltage direct current (HVDC) transmission facility between Tjele (Denmark) and Kristiansand (Norway). It is owned and operated by Statnett in Norway, and Energinet in Denmark. The lines connect the hydroelectric-based Norwegian grid and the wind and thermal power-based Danish grid. In operation it enables more renewable energy in the energy mix, and more efficient use of electricity.

SwePol is a 254.05-kilometre (157.86 mi)-long monopolar high-voltage direct current (HVDC) submarine cable between the Stärnö peninsula near Karlshamn, Sweden, and Bruskowo Wielkie, near Słupsk, Poland. The link was inaugurated in 2000 and can transmit up to 600 MW power at a voltage of 450 kV.

<span class="mw-page-title-main">Submarine power cable</span> Transoceanic electric power line placed on the seabed

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.

<span class="mw-page-title-main">Energy in Denmark</span> Energy and electricity production, consumption, import and export in Denmark

Denmark has considerable sources of oil and natural gas in the North Sea and ranked as number 32 in the world among net exporters of crude oil in 2008. Denmark expects to be self-sufficient with oil until 2050. However, gas resources are expected to decline, and production may decline below consumption in 2020, making imports necessary. Denmark imports around 12% of its energy.

<span class="mw-page-title-main">Wind power in Denmark</span>

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. Furthermore, Denmark has - as of 2022 - the 2nd highest amount in the world of wind power generation capacity installed per capita, behind only neighboring Sweden.

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.

TenneT is a transmission system operator in the Netherlands and in a large part of Germany.

Nordic electricity market is a common market for electricity in the Nordic countries. It is one of the first free electric-energy markets in Europe and is traded in NASDAQ OMX Commodities Europe and Nord Pool Spot.

The Great Belt power link, also known as the Great Belt electricity link, is a high-voltage direct-current interconnection across the Great Belt between Funen and Zealand connecting two power transmission systems in Denmark.

<span class="mw-page-title-main">Anholt Offshore Wind Farm</span>

Anholt Offshore Wind Farm is a Danish offshore wind power wind farm in the Kattegat, between Djursland and Anholt island. With a nameplate capacity of 400 megawatts (MW), it is one of the largest offshore wind farm in the world and was the largest in Denmark from 2013 to 2019. A cable from the wind farm to Anholt replaces most of the diesel-powered electricity on the island.

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.

Viking Link is a 1,400 MW HVDC submarine power cable between the United Kingdom and Denmark completed in 2023.
