DONG Energy was founded in 2006 when six Danish energy companies merged: DONG, Elsam, ENERGI E2, Nesa, Copenhagen Energy, and Frederiksberg Forsyning.

Activities throughout the value chain
The merger brought together a wide breadth of experience, resources, and activities, including:

• Oil  and natural gas exploration and production
• Electricity generation at power stations and renewable energy facilities
• Gas and electricity distribution
• Sales and energy consulting

Oil and natural gas exploration and production
Since 1984, DONG has explored for and produced oil and natural gas. As a state-owned company, we have also established Denmark’s natural gas infrastructure. Subsequently, DONG has owned and operated the natural gas distribution grids in Southern Jutland, West Zealand, and South Zealand. In addition, DONG has established renewable energy facilities and, after electricity market deregulation, has actively participated in energy trading.
 

Power stations and international wind power projects
Elsam has more than 50 years of experience generating electricity at seven primary power stations and 14 small-scale power stations in Jutland and Funen. The same is true of ENERGI E2 which operated seven primary power stations and 10 small-scale power stations and international wind power projects in East Denmark. Since the 1970s, both companies have converted their production processes and facilities from solely oil-based to more diverse sources of energy. A few ways they diversified include:

• Introducing the world’s most efficient coal-fired process
• Recycling residual products from the process
• Amassing international cutting-edge expertise in wind energy
• Developing energy resources from waste and straw

Trading on North European energy markets
In step with energy market deregulation in the EU’s member states, DONG Energy has increased its own international activities significantly and is now an international energy company focussed on North European energy markets. We supply energy to customers in the Danish, Swedish, German, and Dutch markets and trade on European energy exchanges. We have access to long-term energy supplies and infrastructure in Denmark and abroad to ensure a convenient, flexible supply of energy.

Supplying electricity to North Zealand and Greater Copenhagen
The history of the three power utilities – Nesa, Copenhagen Energy and Frederiksberg Forsyning – goes back to the beginnings of power generation in the early 20th century. Since then, their power supply grid has grown to include all of North Zealand, the city of Roskilde, and Greater Copenhagen. After deregulation of the electricity market, they have also been selling electricity and related services to customers outside these grid districts and have developed a powerful profile in the fields of energy consultancy, customer service, and reliable energy supplies.
