Ørsted A/S (formerly DONG Energy) is a power company based in Fredericia, Denmark. It is the largest energy company in Denmark.
The company adopted its current name on 6 November 2017.
The Danish state-owned company Dansk Naturgas A/S was founded in 1972 to manage gas and oil resources in the Danish sector of the North Sea. After some years, the company was renamed to Dansk Olie og Naturgas A/S (DONG), meaning Danish Oil and Natural Gas. At the beginning of the decade of the 2000s, DONG started to expand itself into the electricity market by taking long positions in electricity companies. In 2005, DONG acquired and merged Danish electrical power producers Elsam and Energi E2 and public utility (electricity distribution) companies NESA, Københavns Energi and Frederiksberg Forsyning. The result of the merger was the creation of DONG Energy. The merger was approved by the European Commission on 14 March 2006.
In 2002, one of predecessors of DONG Energy named Elsam installed the 160 MW Horns Rev offshore wind farm, which was the first large scale offshore wind farm in the world.
In 2005, DONG Energy acquired 10.34% in the Ormen Lange gas field (operated by Shell). The share of gas reserves allocated to DONG Energy are approximately 40 billion cubic metres (1.4 trillion cubic feet).
In 2007, DONG Energy entered into the Dutch market. In 2010, it started a cooperation with Dutch nl:Nederlandse Energie Maatschappij. However, in 2014 DONG Energy withdrew its consumer activities from the Dutch market. In 2010, DONG divested Norwegian power companies Salten and Nordkraft. In September 2013, DONG Energy sold a power cable accessing the London Array wind farm to its partners, E.ON and Masdar for around $728 million.
In 2013, DONG Energy finished the construction of the 400 MW Anholt Offshore Wind Farm off the Danish island of Anholt in the Kattegat at a cost of 10 billion Danish kroner (EUR1.35 bln). DONG Energy was the only bidder in the process. As of 2012, DONG Energy had a wind turbine capacity of 794 MW and planned to add another 594 MW in 2013. In 2014 DONG Energy divested its last onshore wind turbines, focusing on offshore wind power. of which DONG Energy had 3,000 MW in 2015;
In 2017, DONG Energy completed decommissioning the world's first offshore wind farm, Vindeby Offshore Wind Farm. Also in 2017, the company decided to phase-out the use of coal for power generation, and it sold off its oil and gas business to Ineos for US$1.05 billion. After selling its oil and gas business the company announced its intention to change its name to Ørsted after the Danish scientist Hans Christian Ørsted, citing that DONG was inappropriate considering they had no oil and natural gas assets under ownership any more.
Before divestment of its oil and gas upstream assets to Ineos in 2017, DONG Energy's core areas of oil and gas exploration and production laid in southern part of the Norwegian North Sea and the Danish part of the North Sea, Barents Sea, west of Shetland, and in the mid Norway (gas production). The reserve base was expected to be 570 million barrels (91,000,000 m3) of oil equivalent. In 2016, it produced 100,000 barrels per day (16,000 m3/d) of oil equivalent.
In 2016, DONG Energy agreed to sell its oil and gas pipelines to Energinet.dk. It owned oil and gas pipelines which extend from the Danish part of the North Sea to Nybro and the Swedish gas transmission network (Nova Naturgas). DONG Energy co-owned the Tyra West - F3 pipeline pipelines, which create a link from the North Sea Danish section to the Netherlands natural gas hub in Den Helder, the DEUDAN pipeline from Jutland to north of Hamburg in Germany, and the Langeled pipeline from Nyhamna terminal in Norway to Easington in the UK. DONG Energy also owned a share of the Norwegian gas pipeline system.
