E.ON SE is one of Europe's largest energy companies, headquartered in Essen, Germany. The company focuses on energy networks and customer solutions, operating electricity and gas distribution infrastructure across several European markets. Following the separation of its conventional power generation and energy trading business into Uniper in 2016, E.ON repositioned itself around networks, infrastructure, and retail energy services.
E.ON serves millions of customers across Europe, with significant operations in Germany, Sweden, the United Kingdom, the Czech Republic, Hungary, and Romania, among other markets. Its core activities include the operation of electricity distribution networks, energy retail, and increasingly, solutions tied to the energy transition - such as smart metering, electric vehicle charging infrastructure, and heat pump installations.
The company employs tens of thousands of people across its European operations. Its business is structured around two main segments: Energy Networks, which manages regulated grid infrastructure, and Customer Solutions, which supplies electricity, gas, and related services to residential and business customers. E.ON is listed on the Frankfurt Stock Exchange and is a constituent of the DAX index.
In recent years, E.ON has expanded its footprint in energy infrastructure through the acquisition of innogy's network and retail operations in 2020, significantly increasing its scale across Europe. The company has positioned itself as a key player in facilitating the broader shift toward decarbonised, distributed energy systems.
