PreussenElektra

During its existence, it was the electric utility for Schleswig-Holstein, Lower Saxony, and parts of North Rhine-Westphalia and Hesse.

[1] During World War II, the German electricity industry was targeted by Allied bombers.

[1] In 1957 PreussenElektra and NWK, together with other electricity utilities, founded a nuclear energy research company Studiengesellschaft für Kernkrafte GmbH.

In 1961–1962, NWK together with the Danish utility Det Jyskfynske Elsamarbedje (ELSAM; now part of Energinet) completed the 220 kV link from Flensburg to Aabenraa in Denmark.

At the same time VEAG was sold to Hamburgische Elektricitäts-Werke AG (HEW), now 50Hertz Transmission GmbH.

The PreussenElektra power grid was operated by the regional control center at the 220/110 kV substation in Lehrte near Hannover since 1929. Most of the electricity pylons were constructed together with the substation in the 1930s and have the typical Donaumast design used by the company.
