Careers at E.ON


E.ON aims to provide reliable and efficient energy solutions – including the provision of electricity, gas, and steam – to residential, commercial, industrial and public sector customers across Europe.

Business segments

E.ON has four core global units that are also reportable business segments:

  • Generation, comprising the operation of conventional power generation assets – including fossil, biomass, and nuclear facilities – across Germany, the UK, Sweden, France, and the Benelux countries;
  • Renewables, comprising the development, implementation and operation of renewable energy solutions;
  • Global Commodities, comprising the purchase and sale of electricity, natural gas, liquefied natural gas, oil, coal, freight, and carbon allowances on the wholesale market, as well as the management and development of assets at several phases of the gas value chain, such as pipelines, long-term supply contracts, and storage facilities; and
  • Exploration and Production, comprising the Company’s operation of oil and gas exploration and production projects.


E.ON was established in 2000 by way of a merger between VEBA and VIAG, two well-established energy operators. Both VIAG and VEBA were set up in the 1920s as holding companies for state-owned industrial businesses.  The two companies were privatised later in the 20th Century and were listed on the Deutsche Aktien-Index, going on to establish themselves among Europe’s leading commercial energy operators.

Following the 2000 merger, E.ON embarked on a series of acquisitions. The Company gained access to the UK and US markets through its 2001 purchase of Powergen, and in 2002 became the sole owner of German operator Ruhrgas. In 2008 E.ON completed the acquisition of a portfolio of assets in Italy, Spain, and France from Italy’s Enel and Spain’s Endesa, in total boosting its generating capacity by 12.2 GW. This expansion has continued, with the Company establishing a power generation network across Germany, the UK, Sweden, France, and the Benelux countries, and additional operations across Romania, Russia, Hungary, Italy, Spain, Poland, and the Czech Republic.

E.ON’s shares are traded on the Börse Frankfurt. It is one of the world’s largest energy groups, with a current market capitalisation of €16.60 billion.
