Ørsted has its origin in the Danish state-owned company Dansk Naturgas A/S. The company 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 the 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.

As of 2020, the company is the world's largest developer of offshore wind power, accounting for 29% of global installed capacity and producing 88% of its energy from renewable sources. The company has a goal of net-zero generation by the year 2025 and no carbon emissions by 2040.
