The story
Founded by Prussia on Oct 1927.1
Early years
PreussenElektra was established in Berlin in 1927 when electricity suppliers Grosskraftwerk Hannover AG, Preussische Kraftwerke Oberweser AG, and Gewerkschaft Grosskraftwerk Main-Weser merged to form PreussenElektra. It operated two thermal power stations, Borken in Hesse and Ahlem in Hanover, and eight hydroelectric stations. The company was to oversee the electricity interests of the Prussian state. The Prussian state also owned the Nordwestdeutsche Kraftwerke AG (NWK), which merged with PreussenElektra in 1985, Ostpreussenwerke AG and the Überlandwerke and Strassenbahnen Hannover AG. Since 1929, PreussenElektra was owned by VEBA holding company.
In 1928–1931, in partnership with municipalities, PreussenElektra founded several regional electricity suppliers. These included Schleswig-Holsteinische Stromversorgungs-AG (now: Schleswig-Holstein Netz AG), Stromsversorgungs-AG Oldenburg-Friedland (now: EWE AG), Elektrizitäts-Aktiengesellschaft Mitteldeutschland (now: EAM GmbH & Co. KG), and Hannover-Braunschweigische Stromversorgungs-AG (now part of Avacon). PreussenElektra also acquired stakes in Braunschweigische Kohlen-Bergwerke AG, Westpreussische Überlandwerke Marienwerder GmbH, and Thüringer Gasgesellschaft (Thüga AG).
Nazi Germany (1933–1945)
In 1937, the annual electricity output of PreussenElektra exceeded 1 TWh. During World War II, the German electricity industry was targeted by Allied bombers. As a result, the construction of the hard coal station in Lahde was disrupted. After the war, PreussenElektra's assets in East Germany came under state control and the headquarters of PreussenElektra were moved from Berlin to Hanover in 1947.
