E.ON SE is a German electric utility company based in Essen, North Rhine-Westphalia, Germany. It is the world's largest investor-owned energy service provider. The name comes from the Greek word aeon which means age.
The company is a component of the Euro Stoxx 50 stock market index, DAX stock index and a member of the Dow Jones Global Titans 50 index.
It operates in over 30 countries and serves over 33 million customers. Its chief executive officer is Dr. Johannes Teyssen.
E.ON was created in 2000 through the merger of VEBA and VIAG. In 2016, it separated its conventional power generation and energy trading operations into a new company, Uniper, while retaining retail, distribution and nuclear operations. E.ON sold its stake in Uniper through a stock market listing and sold the remaining stock to the Finnish utility Fortum.
