Nienke Homan, a member of the Groningen Provincial Executive, Marijke van Beek, mayor of Eemsmond, and TenneT COO Ben Voorhorst together performed the opening ceremony by starting the first pile-driving procedure. The ceremony was also attended by representatives of Siemens, which is responsible for the project\u2019s electrical installations.\n\n<figure id=\"attachment_3054\" aria-describedby=\"caption-attachment-3054\" style=\"width: 1024px\" class=\"wp-caption alignnone\"><img loading=\"lazy\" decoding=\"async\" class=\"size-full wp-image-3054\" src=\"https:\/\/www.groningen-seaports.com\/wp-content\/uploads\/Eerste-paal-COBRAcable_kl-1.jpg\" alt=\"PHOTO: The first pile-driving ceremony for the green electricity highway between the Netherlands and Denmark in Eemshaven.\" width=\"1024\" height=\"683\" \/><figcaption id=\"caption-attachment-3054\" class=\"wp-caption-text\">PHOTO: The first pile-driving ceremony for the green electricity highway between the Netherlands and Denmark in Eemshaven.<\/figcaption><\/figure>\n\n<div class=\"section the_content has_content\">\n<div class=\"section_wrapper\">\n<div class=\"the_content_wrapper\">\n\nMinister Henk Kamp of Economic Affairs commented: \u2018The Cabinet is committed to reducing the demand for energy by implementing energy conservation measures and promoting the renewable generation of electricity and heat. The new high-voltage interconnector between the Netherlands and Denmark is important to achieving the Netherlands\u2019 energy objectives. This subsea cable link will increase the security of supply and will provide additional capacity for transporting renewably generated wind energy between the two countries.\u2019\n\n<strong>Sustainable international energy landscape<\/strong>\n\u2018The COBRAcable will play a key role in realizing a truly sustainable international energy landscape,\u2019 says TenneT COO Ben Voorhorst. \u2018Via this cable, the Netherlands and Denmark will be able to exchange electricity in a convenient, safe and environmentally friendly manner. For instance, the Netherlands will be able to important more renewable wind energy from Denmark. During periods of little wind, the cable will increase the security of electricity supplies in Denmark. The interconnector will also be designed in such a way as to enable the connection of an offshore wind farm at a later stage.\u2019\n\n<strong>About the COBRAcable<\/strong>\nThe COBRAcable will have a capacity of 700 MW, will be approx. 325 kilometres long, and will run from Eemshaven (the Netherlands) to Endrup (Denmark) via the German sector of the North Sea. The connection will be constructed as a High-Voltage Direct Current (HVDC) cable, since the use of DC technology minimizes transmission losses over long distances and therefore virtually eliminates any loss of renewable electricity. Two onshore converter stations \u2013 one in the Netherlands and one in Denmark \u2013 are needed to connect the cable to the existing grids.\n\nThese stations will convert the electricity from direct to alternating current or vice versa (depending on the transmission direction), and will feed it into the Dutch or Danish onshore transmission grid in order to supply electricity to homes and businesses.\n\n<strong>Role of Siemens<\/strong>\nSiemens is responsible for constructing the electrical installations in the converter stations in the Netherlands and Denmark. The company will also undertake the civil engineering of the converter station in the Netherlands. \u2018We are looking forward to helping to construct this innovative European electricity connection together with TenneT, Energinet.dk and Prysmian,\u2019 said Bernard Fortuyn, a member of the Managing Board of Siemens Netherlands. \u2018Siemens is currently working on no less than five of these \u201celectricity highways\u201d in Europe. If we include the COBRAcable, we will help bring 4.6 gigawatts of capacity online in the coming years. In this way Siemens is making a significant contribution to integrating the different national electricity systems into a single European grid.\u2019\n\n<strong>Other subsea electricity cables<\/strong>\nThe COBRAcable is not the first subsea electricity connection constructed by TenneT. In 2008 the TSO completed the NorNed cable between the Netherlands and Norway (capacity: 700 MW, length: 580 km). This was followed in 2011 by the BritNed cable between the Netherlands and the UK (capacity: 1,000 MW, length: 260 km). In addition to the new COBRAcable, TenneT is currently also working on the NordLink project, a 1,400 MW subsea cable link between Germany and Norway that is expected to be completed in 2020.\n\n<strong>EU support<\/strong>\nThe COBRAcable is a cross-border project of European significance. The European Commission has therefore allocated a subsidy to this project under the EU Economic Recovery Plan, and has designated the COBRAcable as a Project of Common Interest (PCI). This preferential status is assigned to energy infrastructure projects that meet a number of specific criteria.\n\n<strong>Facts and figures<\/strong>\n<ul>\n \t<li>High-Voltage Direct Current (HVDC) link with a total length of 325 km<\/li>\n \t<li>Capacity: 700 MW; voltage level: 320 kV<\/li>\n \t<li>Connection sites to the onshore grid: converter stations in Eemshaven (Netherlands) and Endrup (Denmark)<\/li>\n \t<li>Scheduled to enter into service in 2019<\/li>\n<\/ul>\n<\/div>\n<\/div>\n<\/div>\n","protected":false},"excerpt":{"rendered":"<p>Cable has 700 MW capacity for exchange of renewable energy, sufficient to meet the annual electricity needs of approx. 700,000 Dutch households Cross-border electricity connection (interconnector) will improve security of supply, help stabilize energy prices in both countries, and facilitate realization of climate change targets New step in integration of European energy markets Today TenneT&#8230;<\/p>\n","protected":false},"author":3,"featured_media":2065,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"_kad_blocks_custom_css":"","_kad_blocks_head_custom_js":"","_kad_blocks_body_custom_js":"","_kad_blocks_footer_custom_js":"","_kad_post_transparent":"","_kad_post_title":"","_kad_post_layout":"","_kad_post_sidebar_id":"","_kad_post_content_style":"","_kad_post_vertical_padding":"","_kad_post_feature":"","_kad_post_feature_position":"","_kad_post_header":false,"_kad_post_footer":false,"_kad_post_classname":"","footnotes":""},"categories":[45],"tags":[],"class_list":["post-12734","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-energy"],"yoast_head":"<!-- This site is optimized with the Yoast SEO plugin v27.9 -
