DONG Energy is an integrated energy company with leading market positions in Denmark and other key areas of Northern Europe. DONG Energy A/S is a holding company registered in Denmark.

In the recent years DONG Energy has shifted focus from being a source of natural gas, whole seller, explorer and gas and oil producer to being an integrated company with activities within the entire value chain.

Founded in 1972
DONG Energy was founded as Dansk Naturgas A/S by the Danish state on 27 March 1972 (the name was changed to Dansk Olie og Naturgas A/S in 1973, to DONG in 2002 and to DONG Energy A/S in 2006). The company was created as a driving force for the development of energy activities in Denmark.

DONG Energy
The company has expanded substantially through organic growth and acquisitions both in Denmark and in Europe. Most significant was the acquisition of five Danish energy companies in 2005: Elsam, Energi E2, Nesa, KE Holding and Frederiksberg Elnet.

In parallel to these acquisitions DONG Energy acquired 10.34% of the gas filed Ormen Lange in February 2005. This acquisition was a major step in the direction of a change from oil to natural gas. Commercial production from the Ormen Lange field commenced in October 2007.
