Introduction
e.on was a German energy company that operated primarily in the production, transmission, and distribution of electricity and natural gas. Founded in 1999 through the merger of Westdeutsche Energieversorgung AG and Norddeutsche Energieversorgung AG, the company established its headquarters in Düsseldorf and grew to become one of the largest independent power producers in Germany. Over its history, e.on diversified its portfolio to include renewable energy assets, participated in large-scale energy trading, and pursued strategic acquisitions to expand its service offerings. In 2020, e.on merged with EnBW – Energie Baden-Württemberg AG, and its operations were integrated into the new entity, marking the end of e.on as an independent corporate brand.
History
Origins and Formation
The roots of e.on can be traced back to the 1960s when Westdeutsche Energieversorgung AG and Norddeutsche Energieversorgung AG were established as regional utilities in North Rhine-Westphalia. Both companies managed electricity and gas supply for their respective districts and were involved in local infrastructure development. In the late 1990s, amid a wave of consolidation in the German utilities sector, the two firms agreed to merge in order to increase operational efficiency and to broaden their geographic reach. The merger was finalized in 1999 and the newly formed entity adopted the name e.on, a stylized abbreviation of the German words for “energy” (Energie) and “on,” signifying continuity and modernity.
Expansion and Development
Following its establishment, e.on pursued aggressive expansion through both organic growth and strategic acquisitions. The company invested heavily in conventional power generation, including coal and gas-fired plants, to secure a stable generation base. Simultaneously, it recognized the emerging importance of renewable energy and began acquiring stakes in wind farms and solar parks across Germany and neighboring countries. In 2006, e.on entered the electricity retail market, offering tariff plans to residential and business customers. This diversification helped stabilize revenue streams and positioned the company as a comprehensive energy provider.
