Since its founding, EWE has been deeply connected to its regions and has grown into an experienced energy supplier over the decades. The company’s roots date back to 1930, when the newly established Oldenburgische Stromversorgungs AG (Oldag) merged with Weser-Ems-Stromversorgungs AG (Wesag) to form Stromversorgungs AG Oldenburg-Ostfriesland (Strosag). This company later evolved into EWE AG, which remains predominantly in municipal ownership today.
In the 1960s, EWE entered the natural gas supply sector, laying a crucial foundation for its future development. In 1962, EWE launched its first natural gas supply operations and, in 1975, signed its first import contract for Dutch natural gas, becoming the leading gas supplier in the Oldenburg region and later in Brandenburg.
