The business model of PNE AG includes planning, building, financing, operating and selling of wind farms.
The company received the permission for the first own offshore project "Borkum Reef Ground" approximately four years after examination by the competent Bundesamt für Seeschifffahrt und Hydrographie (Federal Maritime and Hydrographic Agency) in February 2004.
This group included the "Windpark Marschland GmbH" in 1995, which changed its name in 1998 to Plambeck Neue Energien AG as a company limited by shares (Aktiengesellschaft).
Wolfgang von Geldern accompanied Norbert Plambeck during the Initial public offering and belonged to the Board from 1998 until 2008.
In August 2019 Morgan Stanley Infrastructure announced an offer at €4 per share or €306m to acquire PNE AG.
